CB12 1K EPROM/ROM 8-Bit MCU with I/O type
GENERAL DESCRIPTION
The CB12 series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bit CMOS microcontrollers. It employs a RISC architecture with only 38 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 CB12 series consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),Oscillator Start-up Timer(OST), Watchdog Timer, EPROM/ROM, SRAM, tri-state I/O port, Power saving SLEEP mode, real time programmable clock/counter, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are three oscillator configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator.
The CB12 address 1K×13 of program memory.
The CB12 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.
