MICROCHIP PIC16F870 8-bit Flash Microcontroller, 28-Pin SDIL

The MICROCHIP PIC16F870-I/SP is a powerful mid-range, 8-bit microcontroller from the widely recognised PIC16 family, combining high performance with straightforward programming. It features a robust CMOS flash-based architecture, enabling 200 nanosecond instruction execution for efficient real-time processing. With only 35 single-word instructions to learn, it offers an accessible entry point for both novice and experienced embedded systems developers.

This device packs a comprehensive set of features into a compact 28-pin package. It provides 3.5kB of program memory and 128 bytes of data RAM, alongside a versatile 5-channel, 10-bit analogue-to-digital (A/D) converter for precise sensor interfacing and measurement applications. Capable of operating at a maximum frequency of 20MHz across a wide voltage range of 2V to 5.5V, it offers excellent flexibility for various power-constrained designs.

Key technical features include an 8-level hardware stack for efficient subroutine handling, hardware interrupt management, and extensive power management options such as a Power-Saving SLEEP mode, Power-On Reset (POR), and a Watchdog Timer (WDT). The 64 bytes of EEPROM data memory allow for non-volatile storage of configuration parameters. A significant advantage is the In-Circuit Serial Programming (ICSP) and in-circuit debugging capability via two pins, which greatly simplifies development, testing, and firmware updates without removing the chip from the circuit board.

Encased in a through-hole 28-pin SDIL package, this microcontroller is well-suited for prototyping and production. Its 22 I/O pins and USART interface provide ample connectivity for peripherals and serial communication. With an operating temperature range of -40°C to 85°C, it is engineered for reliability in demanding environments.

Ideal for a wide spectrum of applications, the PIC16F870 is a versatile
