PIC12C67X 8Bit CMOS Microcontrollers

PIC12C67X 8Bit CMOS Microcontrollers
A new range of 8 pin DIP or SOIC OTP microcontrollers suited to the user seeking a general
purpose device without the added cost of unnecessary peripherals and the associated large pin
counts. They have between 512 and 2048 words of program memory and between 25 and 128
bytes of user RAM.
