GENERAL DESCRIPTIONPtf嘉泰姆

The CXLC8LT0481 is an 8-bit single chip micro-controller. Its memory capacity includes 80*8 bits SRAM and 2K *13 bits ROM. Other features include timer RTC, timer TCC, 4 groups I/O port. It can also provide the interrupt function and the wakeup function from sleep and idle mode. A programmable sound generator is integrated in  CXLC8LT048. It has touch sensor function and LCD driver function. The LCD driver is capable of driving up to 32 segments and up to 4 commons. The LCD driver supports 1/2 bias, 1/3bias and 1/3 duty, 1/4 duty.Ptf嘉泰姆
