PIC16F83-04/SO

18引脚闪存/ EEPROM的8位微控制器 18-pin Flash/EEPROM 8-Bit Microcontrollers

GENERAL DESCRIPTION

The PIC16F8X is a group in the PIC16CXX family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers. This group contains the following devices:

• PIC16F83

• PIC16F84

• PIC16CR83

• PIC16CR84

All PICmicro™ microcontrollers employ an advanced RISC architecture. PIC16F8X devices have enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with a separate 8-bit wide data bus. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches which require two cycles. A total of 35 instructions reduced instruction set are available. Additionally, a large register set is used to achieve a very high performance level.
