8-Pin, 8-Bit CMOS Microcontroller with
EEPROM Data Memory
Devices:
PIC12CE518 and PIC12CE519 are 8-bit microcontrol-
lers 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

- EXTRC: External low-cost RC oscillator
- XT: Standard crystal/resonator
- LP: Power saving, low frequency crystal
CMOS Technology:
• Low-power, high-speed CMOS EPROM/
EEPROM technology
• Fully static design
• Wide temperature range:
- Commercial: 0°C to +70°C
- Industrial: -40°C to +85°C
- Extended: -40°C to +125°C
• Wide operating voltage range:
-Commercial: 3.0V to 5.5V
-Industrial: 3.0V to 5.5V
-Extended: 4.5V to 5.5V
• Low power consumption
- < 2 mA typical @ 5V, 4 MHz
- 15 µA typical @ 3V, 32 kHz
- < 1 µA typical standby current
