Description
This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS Flash/EEPROM-based 8-bit microcontroller packs Microchip’s powerful PIC® architecture into an 18-pin package. The same device can be used for prototyping and production and the end application can be easily updated without removing the device from the end product via the ICSP. Easily adapted for automotive, industrial, appliances low power remote sensors, electronic locks and security applications.
• Only 35 single word instructions to learn • All instructions single-cycle except for program branches which are two-cycle • Operating speed: DC – 20 MHz clock input DC – 200 ns instruction cycle • 1024 words of program memory • 68 bytes of Data RAM • 64 bytes of Data EEPROM • 14-bit wide instruction words • 8-bit wide data bytes • 15 Special Function Hardware registers • Eight-level deep hardware stack • Direct, indirect and relative addressing modes • Four interrupt sources: – External RB0/INT pin – TMR0 timer overflow – PORTB<7:4> interrupt-on-change – Data EEPROM write complete
