The CX8PB53B is a low-cost, high speed, high noise immunity, OTP-based 8-bit CMOS microcontrollers. It employs a RISC architecture with only 42 instructions. All instructions are single cycle except for program branches which take two cycles. The easy to use and easy to remember instruction set reduces development time significantly.
The CX8PB53B consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),Oscillator Start-up Timer(OST), Watchdog Timer, OTP, SRAM, tri-state I/O port, I/O pull-high/open-drain/pull-down control, Power saving SLEEP mode, real time programmable clock/counter, Interrupt, Wake-up from SLEEP mode, and Code Protection for OTP products
