一.产品概述bGD嘉泰姆

         The CX8PA76 is a low-cost, high speed, high noise immunity, OTP-based 8-bit CMOS microcontrollers. It  employs a RISC architecture with 54 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 significantlybGD嘉泰姆

          The CX8PA76 consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),Watchdog Timer, OTP, SRAM, tri-state I/O port, I/O pull-high control,Power saving SLEEP mode, 5 real time programmable clock/counter, Interrupt, Wake-up from SLEEP mode, and Code Protection for OTP products.There are eight oscillator configurations to be chosen from, including the power-saving LF (Low Frequency) oscillator and cost saving internal RC oscillator.bGD嘉泰姆

        The CX8PA76 address 2K×16 of program memory.bGD嘉泰姆

        The CX8PA76 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.bGD嘉泰姆

        The CX8PA76 provides total 9 channel 12bit AD converter with ±2LSB resolution.  bGD嘉泰姆
