2、 Detailed explanation of pin functions
▲ Note:When the DIO port outputs data, it is an N-tube open drain output. When reading keys, an external pull-up resistor of 1K-10K is required. Our company recommends a 10K pull-up resistor. DIO
Control the action of the N tube at the falling edge of the clock, and the reading is unstable at this time. You can refer to Figure 2, and the reading only stabilizes at the rising edge of the clock.
The 48 pins of CXLE88175 each undertake critical functions, and a correct understanding of their definition is the foundation of hardware design.
2.1. Key pin description:
• DIO (pin 24)Bidirectional data cable, used for input and output of serial data, requires external connection of 10kΩ Pull up the resistor.
• SCLK (pin 25)Serial clock input, controlling data synchronization.
• STB (pin 26)Chip selection signal, used to initialize communication sequence.
• SEG1-SEG15 (pins 37-48, 1-3)Segment driven output, used to control the display of LED segments.
• GRID1-GRID8 (pins 5-6, 8-11, 13-14): Bit driven output, controls digital tube bit selection.
• KEY1-KEY8 (pins 32-35, 15-18)Touch button input port, grounded when not in use.
• OMS (pin 22)Output mode selection (suspended for serial mode, grounded for parallel mode).
• LSC (pin 21)Low power mode selection (suspended as normal mode, grounded as ultra-low power mode).
2.2. Design considerations:
• All unused touch button input ports must be grounded to avoid interference.
• The VDD and GND pins should be fully connected, and decoupling capacitors should be placed near the chip to enhance stability.
• It is recommended to parallel 100pF capacitors for communication lines (DIO, SCLK, STB) to suppress high-frequency noise.
3、 Instruction System and Communication Protocol
The first byte input by DIO after the falling edge of STB is used as an instruction. After decoding, take the highest B7 and B6 bits to distinguish between them
Same instruction.
If the STB is set to a high level during instruction or data transmission, serial communication is initialized, and the instruction or data being transmitted is invalid
The instructions or data transmitted in advance remain valid.
CXLE88175 achieves display and button function configuration through three basic commands:
3.1. Data Command Settings (Command Header: 01xx xx00)
This instruction is used to set data write and read, and bits B1 and B0 do not allow setting 01 or 11.
3.1.1 Used to select data read/write mode:
• 0100 0000Write data to the display register
• 0100 0010Read key data
3.1.2 Supports automatic address addition or fixed address mode, facilitating continuous or single point data operations.
3.2. Display control commands (instruction header: 10xx xxxx)
This instruction is used to set the display switch and adjust the display brightness. There are 8 levels of brightness available for adjustment.
• Control display switch and brightness adjustment, supporting 8-level brightness (duty cycle 1/16 to 14/16).
• For example:1000 1111Indicates enabling display and setting the highest brightness.
3.3. Address Command Settings (Instruction Header: 11xx xxxx)
This instruction is used to set the address of the display register. The maximum effective address is 16 bits (C0H-CFH). If the address is set to D0H or higher, the number is
It is ignored until a valid address is set. When powered on, the address is set to C0H by default.
• Set the storage address for displaying data, with a valid address range of C0H to CFH, totaling 16 bytes.
3.4. Key points of communication timing:
• Data is written on the rising edge of SCLK and read on the falling edge.
• The first byte after the falling edge of STB is the instruction, followed by data.
• When reading the button, it is necessary to continuously read 4 bytes of data, and it cannot be skipped or read across bytes.
3.5. Display Register Address
This register stores data transmitted from external devices to CXLE88175 through a serial interface, with a maximum effective address of 16 bytes from C0H-CFH
The units correspond to the SEG and GRID pins of the chip, and the specific allocation is shown in the table below:
When writing LED display data, operate according to the display address from low to high and the data byte from low to high.
▲ Attention:When writing LED display data, operate from low bit address to high bit address and from low bit to high bit byte; Not in use
There are SEG output ports used, write 0 in the corresponding BIT address bit.
4、 Example of Digital Tube Driver Configuration
CXLE88175 can drive a common cathode or common anode digital tube, and the following are typical connection methods:
4.1. Common cathode digital tube driver
Figure 3 shows the schematic diagram of the connection of the common cathode digital tube. If the digital tube displays“ 0” Just need to open from the lower bits to the C0H (GRID1) address
Just start writing 0x3F data. At this point, C0H corresponds to the data of each SEG1-SEG8 as shown in the table below.
• The SEG pin is connected to the LED anode, and the GRID pin is connected to the cathode.
• Display“ 0” Write data 0x3F to address C0H (corresponding to SEG1-SEG6 lighting up).
4.2. Gongyang Digital Tube Driver
Figure 4 shows the schematic diagram of the connection of the Gongyang digital tube. If the digital tube displays“ 0” To address units C0H (GRID1), C2H (GRID2)
Write data 01H in C4H (GRID3), C6H (GRID4), C8H (GRID5), CAH (GRID6), and all other address CCH (GRID7) units
Write data 00H. The corresponding data for each SEG1-SEG8 is shown in the table below.
▲ Attention:Whether driving a common cathode digital tube or a common anode digital tube, the SEG pin can only be connected to the anode of the LED, and the GRID pin can only be connected to the cathode of the LED,
Cannot be reversed.
• The GRID pin is connected to the LED anode, and the SEG pin is connected to the cathode.
• Display“ 0” When writing, corresponding data needs to be written to multiple GRID addresses, such as C0H, C2H, etc. Write 01H.
4.3. Important Notice：
• SEG can only connect to the LED anode, while GRID can only connect to the cathode. Reverse connection may cause chip damage.
• If using blue or white LED (with a voltage drop of about 3V), it is recommended to use a power supply voltage of 5V.
5、 Detailed explanation of touch button functions
5.1 The touch button function of CXLE88175 has the following intelligent features:
• auto-calibrationAutomatically obtain benchmark values after power on, and regularly update them when there is no operation to adapt to environmental changes.
• Anti interference designBuilt in anti voltage fluctuation function to avoid false triggering caused by power supply jitter.
• timeout protectionPress the button for more than 64 seconds to automatically reset and prevent accidental locking.
• Sensitivity adjustmentEach KEY pin can be connected to an external 0-25pF capacitor, allowing for flexible adjustment of sensing sensitivity.
5.2. Output mode selection:
Reading and receiving one BIT are both performed on the rising edge of the clock.
▲ Attention:1. When reading data, it is necessary to set instructions from the 8th rising edge of the serial clock CLK to read data from the falling edge of CLK
Waiting time Twait (minimum 2μ S). Please refer to the timing characteristic table for specific parameters.
• Serial mode (OMS suspended)Output a 16 bit data packet containing key status, checksum, and stop bits.
• Parallel mode (OMS grounded)Output a 4-digit binary code through BIN0-BIN3, representing only a single key.
CXLE88175 also provides parallel interface functionality, allowing key value transfer with external devices. When selecting the parallel interface as the output type, touch
Touching the key value can only reflect one key, not multiple keys at the same time. When there is no touch key pressed, BIN3-BIN0 are all at high level. When there is any
When the button is pressed, BIN3 is at a low level and can be used to wake up the host. BIN2 to BIN0 represent the pressed key values, as shown in the table below:
5.3. Key Scan and Key Scan Data Register
The maximum supported key scan matrix for this chip is 8× 1bit, As shown in Figure 5:
The storage address for key scan data is shown in the table below. First, send the command to read the key, and then start reading the key data BYTE1— BYTE4, Read data from low position on
Start outputting. When the buttons corresponding to the K and KS pins of the chip are pressed, the BIT bit in the corresponding byte is 1.
▲ Attention:1. CXLE88175 can read up to 4 bytes and does not allow multiple reads.
2. Read data bytes can only be read sequentially from BYTE1-BYTE4 and cannot be read across bytes. For example, hardware K0 and KS8
When the corresponding button is pressed, in order to read the data of this button, it is necessary to read the 8th bit of the 4th byte before reading the data.

5.4.5）Touch button function description
The built-in touch button function of CXLE88175 provides a simple and reliable way to meet the need for 8 touch buttons. Only a very small amount is needed
External components can be used to implement touch key applications, providing a two-wire serial interface and binary parallel output for easy communication with external MCUs
Sensitivity adjustment, simply add a capacitor to the touch input pin to adjust different sensitivities. Built in anti voltage fluctuation
Function can also save the cost of an LDO (voltage regulator module).
CXLE88175 offers 2 options to increase application flexibility
1. Working mode
To reduce power consumption. Once any key is touched, the CXLE88175 chip's touch scanning function can be activated, entering working mode and outputting a button shape
The chip has two working modes, standby mode and working mode. If no button is touched within 8 seconds after the system is powered on, it will automatically enter standby mode,
When all keys have not been pressed, 8 Enter standby mode again in seconds.
2. Maximum button duration
To minimize unintentional key detection such as accidentally touching the sensing electrode, the chip is equipped with a maximum key duration function internally.
When a touch button is pressed, the internal timer starts counting. Once the button is pressed for too long, exceeding approximately 64 seconds, the touch chip will
Ignore the state of the touched key, recalibrate, obtain a new reference value, and reset the output state to the initial state.
3. Automatic calibration function
After power on, the chip will initialize and obtain the first reference value. If it is not pressed within 1 second in normal mode or 32 seconds in standby mode
When the key is pressed, the touch chip will automatically calibrate the reference value after a fixed time period, so that the reference value can be dynamically adjusted according to the external environment
The change.
4. Voltage fluctuation resistance function
The chip has built-in anti voltage fluctuation function, which can prevent touch button misoperation caused by transient voltage drop due to high peripheral current driving,
No need to add an LDO (voltage regulator module) to handle voltage drop issues.
5. Sensitivity adjustment
The size and floor area of the electrode (directly below the electrode), or the sensitivity can be adjusted by changing the thickness of the insulation material. At the same time, CXLE88175 provides touch input pins
Adjusting the sensitivity of touch buttons according to user needs is a very important consideration in most applications. It can be achieved by changing the PCB circuit
Adjust different sensitivity requirements by adding capacitors.
6. Serial interface
The chip is equipped with a serial interface that allows for simple communication with external devices. When the touch chip detects that the touch key is pressed, it will
BIN3 pin outputs a low level, which can wake up the host. After receiving the low level, the host inputs a clock signal through BIN2 pin and reads back from BIN3 pin
Key value. When a low level is input at pin BIN2, the touch chip prepares data, and after pin BIN2 sends a high level, the host reads data from line BIN3.
Read data in groups of 8 clock signals each time. You can also directly read the key value through polling without waiting for the Start bit. When data is read incorrectly
At this time, it takes about 6ms to read again.
When the BIN2 pin receives a clock signal, the touch chip will generate a 16 bit data byte and remove it from the BIN3 pin. Among them, Bit11
Bit8 generates a checksum to represent the total number of touched keys. For example, the checksum is“ 0010” This means that two keys have been touched. to
So which button is touched, you can check the status of Bit7 to Bit0 bits. Bit7~Bit0 are used to indicate whether the corresponding touch keys Key8~Key1 are
Touched. If it is 0, it indicates that the corresponding key has been touched, and if it is 1, it indicates that the corresponding key has not been touched.
Start bit: When the button state changes, the Data pin outputs a low potential to wake up the host, and the host reads the key value.
Bit0：Key1 Status (0=touch, 1=touch); Untouched)
Bit1：Key2 Status (0=touch, 1=touch); Untouched)
Bit2：Key3 Status (0=touch, 1=touch); Untouched)
Bit3：Key4 Status (0=touch, 1=touch); Untouched)
Bit4：Key5 Status (0=touch, 1=touch); Untouched)
Bit5：Key6 Status (0=touch, 1=touch); Untouched)
Bit6：Key7 Status (0=touch, 1=touch); Untouched)
Bit7：Key8 Status (0=touch, 1=touch); Untouched)
Bit11-8: Checksum --“ 0” The total number of touched keys.
Bit15~Bit12: Stop bit, always“ 1010B”
