The CX8P73B is a low-cost, high speed, high noise immunity, EPROM-based 8-bit CMOS microcontrollers. It employs a RISC architecture with 33 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 CX8P73B consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),Watchdog Timer, EPROM, SRAM, tri-state I/O port, I/O pull-high control, Power saving SLEEP mode, 3 real time programmable clock/counter, Interrupt, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are five oscillator configurations to be chosen from, including the power-saving LF (Low Frequency) oscillator and cost saving internal RC oscillator.
The CX8P73B address 1K×14 of program memory.
The CX8P73B 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.
The CX8P73B provides total 11 channel 10bit AD converter with ±2LSB resolution
Total 11 channel 10bit AD converter with ±2LSB resolution
All instructions are single cycle except for program branches which are two-cycles
14-bit wide instructions
