描述 Description

GENERAL DESCRIPTION
The PIC16C505 from Microchip Technology is a low cost, high-performance, 8-bit, fully static, EPROM/ROM-based CMOS microcontroller. It employs 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. The PIC16C505 delivers performance an order of magnitude higher than its competitors in the same price category. The 12-bit wide instructions are highly symmetrical resulting in a typical 2:1 code compression over other 8-bit microcontrollers in its class. The easy to use and easy to remember instruction set reduces development time significantly.High-Performance RISC CPU:
• Only 33 instructions to learn
• Operating speed:
   - DC - 20 MHz clock input
   - DC - 200 ns instruction cycle
• Direct, indirect and relative addressing modes for
   data and instructions
• 12-bit wide instructions
• 8-bit wide data path
• 2-level deep hardware stack
• Eight special function hardware registers
• Direct, indirect and relative addressing modes for
   data and instructions
• All single cycle instructions (200 ns) except for
   program branches which are two-cyclePeripheral Features:
