Microchip PIC16F630/676 Microcontroller User Reference Manual
This document is the user reference manual for the Microchip PIC16F630/676 high-performance RISC microcontroller. It provides specific information on the device, including its architecture, memory organization, and peripheral modules. The manual is intended to be used in conjunction with the PICmicro Mid-Range Data Sheet (DS33023_CN) for a complete understanding of the chip structure and operation.
The PIC16F630/676 features a 35-instruction set where all instructions except branches are single-cycle. It supports a wide operating voltage range of 2.0V to 5.5V and offers various power-saving modes. Key peripherals include an 8-bit Timer0, an enhanced 16-bit Timer1, a comparator, and a 10-bit A/D converter (on the PIC16F676 only). The device includes 1K x 14 words of Flash program memory and 128 bytes of EEPROM data memory. This manual is written in Chinese.
