The CXLC8LP129B is an 8-bit single chip micro-controller, it is one of CXLC8 series products. Its memory capacity includes 144 bytes SRAM, 4K *14 bits OTP ROM. Other features include timer RTC, timer TCC, four groups I/O Port (P1.0~P1.7, P2.0~P2.7, P3.0~P3.5, P4.0~P4.7), a resistor to frequency converter, a programmable sound generator and a LCD module are built in the chip. The LCD module is capable of driving up to 32 segments and up to 4 commons and it supports 1/2 bias and 1/3 bias.(128 dots = 4com* 32seg).
