These features make CXLE88176 particularly suitable for applications that require high-precision display combined with key input, such as smart meters, industrial control panels, medical equipment, etc.
2、 Detailed explanation of pin functions
2.1 The 24 pins of CXLE88176 have clear functions and a reasonable layout for hardware design:
| Pin Name | pin number | Functional Description |
|---|---|---|
| DOUT/DIN | one | Serial data input/output, N-tube open drain output, requires external 10kΩ pull-up |
| SCLK | two | Serial clock input, rising edge reads data, falling edge outputs data |
| STB | three | Chip selection signal, falling edge initialization communication |
| KI | four | Key scan data input |
| SEG1/KS1~SEG10/KS10 | 6~15 | Segment output/key scan multiplexing, built-in 5.2kΩ pull-down resistor |
| SEG11 | sixteen | Segment output, built-in 5.2kΩ pull-down resistor |
| SEG12/GRID7~SEG14/GRID5 | 17~19 | Segment/bit multiplexing output, software configuration required |
| GRID1~GRID4 | 20~21,23~24 | Bit output, built-in 4kΩ pull-up resistor |
| VDD | five | Positive pole of power supply (4V~7V) |
| GND | twenty-two | power ground |
2.2. Design considerations：
• Unused KEY pins should be grounded to avoid interference caused by suspension.
• It is recommended to parallel 100pF capacitor filtering for communication lines (DIN, SCLK, STB).
• 100 μ F electrolytic capacitors and 0.1 μ F ceramic capacitors should be arranged near the power pins for decoupling.
3、 Display Register and Instruction System
3.1. Display Register Address Mapping
The display register of CXLE88176 consists of 14 bytes (00H~0DH), each byte is divided into high 4 bits (HU) and low 4 bits (HL), which control the display content of SEG and GRID respectively. When writing data, operations should be performed in the order of address from low to high and data from low to high.
This register stores data transmitted from external devices to CXLE88176 through a serial interface, with a maximum effective address of 14 byte units from 00H-0DH,
Corresponding to the SEG and GRID pins of the chip respectively, the specific allocation is shown in Figure (2): When writing LED display data, the data should be written from low to high according to the display address
Byte operation from low to high.
▲ Attention: The value stored in the chip display register at the moment of power on may be random and uncertain. In this case, the customer directly sends a screen on command,
There may be display garbled characters. So our company suggests that the customer perform a power on reset operation on the display register, that is, to reset the 14 bit video memory address after power on
All data 0x00 is written in (00H-0DH).
3.2 Important NoticeAfter power on, the display register content is random. It is recommended to first write 0x00 to reset all 00H~0DH before sending the display data to avoid garbled characters.
3.3. Instruction Classification and Format
The instruction is sent through the first byte after the falling edge of the STB, and the top two bits (B7, B6) are used to distinguish the instruction type:
| B7 | B6 | command type |
|---|---|---|
| 0 | 0 | Display mode settings |
| 0 | one | Data command settings |
| one | 0 | Display control commands |
| one | one | Address Command Settings |
3.3. Display mode setting instruction
Used to configure the number of display segments and digits, such as“ 0000 0111” Represents a 7-bit 11 segment mode. When executing this command, the display will be forcibly turned off, and a display on command needs to be sent later.
This instruction is used to set the number of selected segments and bits (4-7 bits, 11-14 segments). When the instruction is executed, the display is forcibly turned off. In
When the display mode remains unchanged, the data in the video memory will not be changed, and the display control command controls the display switch. When powered on, the default display mode is 7 digits and 11 segments.
3.4. Data command settings
Used to select data read/write mode:
• 0100 0000Write display register
• 0100 0010Read key data
• Support automatic address addition（0100 0100）Or fixed address mode（0100 0110）
3.5. Display control commands
Control the display switch and brightness, such as“ 1000 1111” Indicates that the display is turned on and the brightness is 14/16 duty cycle.
3.6. Address Command Settings
Set the storage address for displaying data, with a valid range of 00H~0DH.
4、 Practical application of digital tube driver
4.1. Common cathode digital tube driver
SEG pin is connected to the LED anode, and GRID is connected to the cathode. Display“ 0” When writing 0x3F (binary 0011 1111) to address 00H, corresponding SEG1~SEG6 lights up.
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 order to the 00H (GRID1) address
Just start writing 0x3F data. At this point, 00H corresponds to the data of each SEG1-SEG8 as shown in the table below.
4.2. Gongyang Digital Tube Driver
GRID is connected to the anode, SEG is connected to the cathode. Display“ 0” Write 01H to addresses such as 00H, 02H, and 04H, and write 00H to all other addresses.
Figure 4 shows the schematic diagram of the connection of the Gongyang digital tube. If the digital tube displays“ 0” To address the address unit
Write data 01H in 00H (GRID1), 02H (GRID2), 04H (GRID3), 06H (GRID4), 08H (GRID5), and 0AH (GRID6) respectively, and write the remaining addresses
All 0CH (GRID7) units are written with data 00H. The data corresponding to each SEG1-SEG8 is shown in the table below.
▲ Note: 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
Can be reversed.
4.3. Key RemindersSEG can only be connected to the anode, while GRID can only be connected to the cathode. Reverse connection may cause damage to the chip. When using a blue light digital tube (with a voltage drop of about 3V), it is recommended to supply a voltage of 5V.
5、 Keyboard scanning function and anti-interference design
CXLE88176 supports 10× 1 matrix key scanning, key data is read through 5 bytes (BYTE1~BYTE5), each byte containing two valid key states (B0, B3 bits). When reading keys, they must be read in order and cannot cross bytes.
5.1. Composite button problems and solutions：
When multiple buttons are pressed simultaneously, if they share the SEG line, it may cause a display short circuit. The solutions include:
• Arrange the composite buttons on different K-lines;
• Connect a diode in series between the SEG line and the button;
• Suggest using a combination of the same KS line and different K-lines as a composite button.
5.2. Key Scan and Key Scan Data Register:
The maximum supported key scan matrix for this chip is 1× 10bit, as shown below
The storage address for key scan data is shown below. First, send the read key command, and then start reading 5-byte key data BYTE1— BYTE5, Read data from low order
Start outputting, where B7 and B6 bits are invalid bits and the fixed output is 0. When the buttons corresponding to the K and KS pins of the chip are pressed, the BIT bit in the corresponding byte is 1.
▲ Note: 1. CXLE88176 can read a maximum of 5 bytes and does not allow multiple reads.
2. Read data bytes can only be read sequentially from BYTE1-BYTE5 and cannot be read across bytes. For example, on the hardware, K2 corresponds to KS10
When the key is pressed, in order to read the data of this key, it is necessary to read the 5th bit of the 5th byte before reading the data.
5.3. Key Reuse:The issue with composite buttons: SEG1/KS1-SEG10/KS10 is a combination of display and button scanning. Taking Figure (5) as an example, display the required
To turn on D1 and turn off D2, SEG1 needs to be set to“ 0” , SEG2 is“ 1” If S1 and S2 are simultaneously pressed, it is equivalent to SEG1 and SEG2 being short circuited
D1 and D2 are both illuminated.
Solution:
1. In terms of hardware, the keys that need to be pressed simultaneously can be set on different K-lines as shown in Figure (6)
twoTheThe series diode is shown in Figure (7).
▲ Note: It is recommended to use the same KS but different K keys as composite keys.
6、 Constant current drive characteristics and heat dissipation design
The constant current output stability of CXLE88176 is strong, and the linear operating range requires the SEG pin and GND voltage difference to be less than 4V. Its output current hardly changes with VDS, making it suitable for wide voltage range display requirements.
Calculation of heat dissipation power：
Actual power consumption formula:
Ensure that PD (act)<; PD(max)， Among them, PD (max)=(Tj - Ta)/Rth (j-a). Reasonable selection of duty ratio and output current should be made during design to avoid overheating.
