         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.Jz2嘉泰姆

        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. There are three oscillator configurations to choose from, including  the power-saving LF (Low Frequency) oscillator and cost saving RC oscillator.Jz2嘉泰姆

         The CX8PB53B address 1K×13 of program memory.Jz2嘉泰姆

          The CX8PB53B can directly or indirectly address its register files and data memory. All special function registers including the program counter are mapped in the data memory  Jz2嘉泰姆
