MK6A12P General Description

The MK6A12P is an 8 bit RISC high performance microcontroller. It is equipped with 1Kx14bits OTP(One Time Programmable) ROM, 48 Bytes RAM, Timer/Counter, Interrupt, LVR(Low Voltage Reset) and I/O ports in a single chip.

MK6A12P Feature

*  ROM size: 1K x 14 bits

*  RAM: 48 x 8 bits

*  STACK: 6 Levels

*  One instruction is built by 4 system clock.

*  Reset mode:

- Power-On reset
