Microchip PIC16LF873A-I/SS 8-Bit Flash Microcontroller Data Sheet
The PIC16LF873A-I/SS is a high-performance, low-power 8-bit microcontroller from Microchip Technology, built on the versatile PIC® architecture. This device is part of the popular PIC16F87X family and is housed in a 28-pin Shrink Small Outline Package (SSOP), making it suitable for space-constrained applications. It is designed to operate across an extensive voltage range of 2.0V to 5.5V, which is a hallmark of its LF (Low-voltage/Low-power) designation, enabling robust performance in battery-powered and portable devices.
At its core, the microcontroller features an enhanced Harvard architecture with a RISC-based CPU. It can execute most instructions in a single cycle, achieving a throughput of up to 5 MIPS at 20 MHz. The PIC16LF873A contains 8 KB of Flash program memory, which supports up to 10,000 erase/write cycles, offering significant flexibility for application development and field updates. It is also equipped with 368 bytes of RAM and 256 bytes of EEPROM data memory for storing critical variables and data that must be retained during power loss.

A key strength of this MCU is its rich set of integrated peripherals. It includes three timer modules (Timer0, Timer1, and Timer2), two Capture/Compare/PWM (CCP) modules for precise control of waveforms and signals, and a 10-bit Analog-to-Digital Converter (ADC) with up to 5 input channels. For serial communication, it provides a Master Synchronous Serial Port (MSSP) that can be configured for either I²C or SPI protocols and a Universal Synchronous Asynchronous Receiver Transmitter (USART) for RS-232 and RS-485 communications.
The device is designed for ultra-low-power operation, supporting multiple power-saving modes, including Sleep mode, where current consumption can drop to just microamps. This makes it ideal for applications where power efficiency is paramount. Furthermore, its robust design includes features like a built-in Watchdog Timer (WDT) and Brown-out Reset (BOR) for enhanced reliability in electrically noisy environments.
