Microchip PIC16LF819-I/SO: A Comprehensive 8-Bit Flash Microcontroller Data Sheet and Product Overview

The Microchip PIC16LF819-I/SO is a high-performance, low-power 8-bit microcontroller built on Microchip’s robust PIC® architecture. This device is engineered to deliver a powerful yet efficient processing core, making it an ideal solution for a wide array of embedded control applications, including consumer electronics, sensor interfaces, battery-powered devices, and automotive systems.

Housed in a compact 20-pin SOIC (SO) package, the PIC16LF819-I/SO is designed for space-constrained applications. Its core feature is the Enhanced Mid-Range core with a 16-level deep hardware stack and an impressive 49 instructions. The microcontroller operates at a maximum frequency of 20 MHz, enabling execution of most instructions in a single clock cycle for optimized throughput and performance.

A key advantage of this MCU is its nanowatt-technology power management. This technology enables extremely low power consumption through multiple dynamically selectable power modes, including Run, Idle, and Sleep. This makes it exceptionally suited for battery-operated and power-sensitive applications where energy efficiency is paramount.

The device boasts a substantial amount of on-chip memory. It features 3.5 KB (2048 words) of self-programmable Flash program memory, which allows for flexible field firmware updates. Additionally, it includes 256 bytes of EEPROM data memory for storing critical application parameters without loss during power cycles and 256 bytes of SRAM for data handling.

The peripheral set integrated into the PIC16LF819-I/SO is rich and versatile, reducing the need for external components and simplifying design. Notable peripherals include:

10-bit Analog-to-Digital Converter (ADC) with up to 11 input channels.

Capture, Compare, and PWM (CCP) module for timing and waveform generation.

Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) for serial communication (RS-232, RS-485, LIN).

Master Synchronous Serial Port (MSSP) that can be configured as either I²C or SPI for communication with other peripherals.

Two 8-bit timers and one 16-bit timer.

The integration of these features into a single package provides a highly capable and self-contained control unit for complex designs.

ICGOODFIND Summary:

The Microchip PIC16LF819-I/SO stands out as a highly integrated, low-power 8-bit microcontroller solution. Its combination of ample Flash memory, a rich set of peripherals (including ADC, EUSART, and MSSP), and advanced power management nanowatt-technology makes it a superior choice for developers designing efficient, compact, and cost-effective embedded systems for a multitude of industries.
