PIC12 Family PIC12F5xx Series Microcontrollers 8位微控制器:

The PIC12F5xxdevices from Microchip Technology are low-cost, high-performance, 8-bit, fully-static, Flash-based CMOS microcontrollers. They employ a RISC architecture with only 33 single-word/ single-cycle instructions. All instructions are single cycle (200 ​μs) except for program branches, which take two cycles.

• In-Circuit Serial Programmin (ICSP)
• Only 33 Single-Word Instructions
• In-Circuit Debugging (ICD) Support, Power-On Reset (POR)
• 8-bit Real-Time Clock/Counter
• Watchdog Timer (WDT) with Dedicated On-Chip RC Oscillator for Reliable Operation
• 6 General Purpose Input Output Pins
• Multiplexed MCLR Input Pin, Internal Weak Pull-ups on I/O Pins
• High current sink/source for direct LED drive
• Wake-on-change, Weak pull-ups
• Applications: Personal Care Appliances, Security System, Low-Power Remote Transmitters/ Receivers
