PIC12C5XX
8-Pin, 8-Bit CMOS Microcontroller
Devices included in this Data Sheet:
PIC12C508 and PIC12C509 are 8-bit microcontrollers
packaged in 8-lead packages. They are based on the
Enhanced PIC16C5X family.
High-Performance RISC CPU:
• Only 33 single word instructions to learn
• All instructions are single cycle (1 µs) except for
program branches which are two-cycle
• Operating speed: DC - 4 MHz clock input
DC - 1 µs instruction cycle
