Microchip PIC16F870 8-Bit Flash Microcontroller 28-Pin SDIL

The Microchip PIC16F870 8-Bit Flash Microcontroller is a mid-range 8-bit microcontroller from the PIC16 family, providing 3.5kB of program memory in a 28-pin SDIL package.

The PIC16F870 combines high performance with straightforward programming. It features a CMOS flash-based architecture and executes instructions in 200 nanoseconds, with only 35 single-word instructions to learn. This makes it an accessible option for both novice and experienced embedded systems developers.

Key Features

• 3.5kB of program memory and 128 bytes of data RAM
• 64 bytes of EEPROM data memory for non-volatile storage of configuration parameters
• 5-channel, 10-bit analogue-to-digital (A/D) converter for sensor interfacing and measurement
• Maximum operating frequency of 20MHz
• Operating voltage range of 2V to 5.5V
• 22 I/O pins and USART interface for peripheral and serial communication
• 8-level hardware stack for efficient subroutine handling
• Hardware interrupt management
• Power-Saving SLEEP mode, Power-On Reset (POR) and Watchdog Timer (WDT)
• In-Circuit Serial Programming (ICSP) and in-circuit debugging via two pins
• Operating temperature range of -40°C to 85°C

Applications

Suited to prototyping and production, the PIC16F870 is designed for embedded systems, sensor interfacing and measurement, and power-constrained designs. In-circuit programming and debugging allow development, testing and firmware updates without removing the chip from the circuit board, which simplifies the development process.

Packaging and Dimensions

The microcontroller is supplied in a through-hole 28-pin SDIL package. The listed dimensions are width 3.3, depth 1.5 and height 4.3, with a weight of 0.001 gm.
