PIC12 Family PIC12CE5xx Series Microcontrollers 8位微控制器 :

The PIC12CE5XX from Microchip Technology is a family of low-cost, high performance, 8-bit, fully static, EEPROM/EPROM/ROM-based CMOS microcontrollers. It employs a RISC architecture with only 33 single word/single cycle instructions. All instructions are single cycle (1 ms) except for program branches which take two cycles.

• Internal 4 MHz RC oscillator with programmable calibration
• EPROM: Up to 1Kx12, RAM: Up to 41B
• 8-bit ADC
• In-circuit serial programming
• 8-bit real time clock/counter (TMR0) with 8-bit programmable prescaler
• Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation
• Power saving SLEEP mode
• All instructions are single cycle (1 µs) except for program branches which are two-cycle
• 5-I/O pins
• Applications: Personal Care Appliances, Security System, Low-Power Remote Transmitters/ Receivers
