Microchip PIC16LF76-I/SO 8-Bit Microcontroller Data Sheet and Technical Specifications

The Microchip PIC16LF76-I/SO is a high-performance, low-power 8-bit microcontroller built on Microchip’s versatile PIC® architecture. This device is engineered to deliver a powerful yet efficient embedded control solution, making it suitable for a wide range of applications, including industrial systems, consumer electronics, sensor interfaces, and battery-powered devices.

Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, the PIC16LF76-I/SO is designed for space-constrained applications requiring surface-mount assembly. The "LF" designation signifies its core capability for low-voltage and low-power operation, a critical feature for portable and power-sensitive designs.

Core Architecture and Performance

At its heart, this microcontroller features an enhanced Harvard architecture with a RISC (Reduced Instruction Set Computing) core. The CPU operates at a maximum frequency of 20 MHz, enabling the execution of most instructions in a single clock cycle. This results in a high throughput of up to 5 MIPS (Million Instructions Per Second), providing responsive performance for complex control tasks.

Memory Configuration

The PIC16LF76 offers a substantial memory footprint for its class:

8 KB of Flash Program Memory: This provides ample space for application code and offers high endurance for repeated reprogramming.

368 bytes of RAM: Used for data storage and manipulation during runtime.

256 bytes of EEPROM Data Memory: This non-volatile memory is ideal for storing critical data such as calibration constants, user settings, or event logs that must be retained even when power is removed.

Advanced Peripheral Integration

A key strength of this microcontroller is its rich set of integrated peripherals, which reduces system component count and overall design complexity:

Analog-to-Digital Converter (ADC): A 10-bit ADC with up to 5 channels allows for precise measurement of analog signals from sensors.

Timers/Counters: It includes three timers/counters (Timer0, Timer1, and Timer2) for applications requiring timing generation, event counting, or capture/compare operations.

Communication Interfaces: The device supports multiple serial communication protocols:

MSSP (Master Synchronous Serial Port): Configurable as either I²C or SPI for communication with peripherals like memory chips, sensors, and other microcontrollers.

USART (Universal Synchronous Asynchronous Receiver Transmitter): Provides a dedicated channel for RS-232, RS-485, and other serial communication standards.

Capture/Compare/PWM (CCP) Modules: Two CCP modules provide flexibility for generating pulse-width modulated (PWM) signals to control motor speed, LED intensity, or for capturing the timing of external events.

Low-Power Characteristics

Operating from a supply voltage range of 2.0V to 5.5V, the PIC16LF76 is optimized for extended battery life. It features multiple power-saving modes, including Sleep mode, where power consumption is reduced to minimal levels (typically in the nanoampere range), allowing the microcontroller to wake on an interrupt or reset.

Development Support

A robust ecosystem of development tools supports the PIC16LF76-I/SO, including the MPLAB® X Integrated Development Environment (IDE), the PICKit™ programmmer/debugger, and a wide array of software libraries and application notes, which significantly accelerate the design and debugging process.

ICGOODFIND Summary:

The Microchip PIC16LF76-I/SO is a highly capable and power-efficient 8-bit microcontroller that combines strong processing performance with an extensive suite of integrated peripherals. Its low-voltage operation, substantial memory, and robust communication interfaces make it an excellent choice for designers tackling complex embedded control challenges, particularly in portable and power-conscious applications.
