12F629 pdf datasheet


12F629 is 8-Bit CMOS Microcontroller. An 8-bit CMOS microcontroller refers to a microcontroller that has an 8-bit central processing unit (CPU) and utilizes complementary metal-oxide-semiconductor (CMOS) technology in its design.

CMOS technology is widely used in integrated circuits due to its low power consumption and high noise immunity characteristics. It allows for efficient use of power, making CMOS microcontrollers suitable for applications where power efficiency is crucial, such as battery-powered devices.

An 8-bit CMOS microcontroller typically includes other essential components, such as random-access memory (RAM), read-only memory (ROM) or flash memory for program storage, input/output (I/O) ports, timers, and various peripherals. These components allow the microcontroller to perform a wide range of tasks and interface with other devices.

This document contains device specific information for the 12F629, PIC12F629/675. Additional information may be found in the PICmicroTM Mid-Range Reference Manual (DS33023), which may be obtained from your local Microchip Sales Representative or downloaded from the Microchip web site. The Reference Manual should be considered a complementary document to this Data Sheet, and is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules.

The PIC12F629 and PIC12F675 devices are covered by this Data Sheet. They are identical, except the PIC12F675 has a 10-bit A/D converter. They come in 8-pin PDIP, SOIC, and MLF-S packages. Figure 1-1 shows a block diagram of the PIC12F629/675 devices. Table 1-1 shows the Pinout Description.
