Updated: 2026-07-24

Overview

The PIC16LF628A-I/SS is an 8-bit microcontroller manufactured by Microchip Technology. It is part of the PIC16F series, known for its low-power consumption and robust performance in embedded applications. The device integrates flash memory for program storage, EEPROM for data retention, and a range of peripherals, making it suitable for diverse control tasks. With a wide operating voltage range (2.0V to 5.5V), the PIC16LF628A-I/SS is ideal for battery-powered and portable devices. Its compact SSOP package (20 pins) allows for space-efficient designs, while its low-power modes extend battery life in energy-sensitive applications.

Structure and Working Principle

The PIC16LF628A-I/SS is built around a RISC-based 8-bit CPU core, offering efficient instruction execution and low power consumption. It includes 3.5 KB of flash memory for program storage, 224 bytes of RAM, and 128 bytes of EEPROM for non-volatile data storage. The microcontroller also features timers, comparators, and a USART module for serial communication. Power management is a key aspect of its design, with sleep modes and watchdog timers to minimize energy use. The device operates on an internal or external oscillator, providing flexibility in clock source selection. Its I/O pins are configurable for digital input/output, analog input, or peripheral interfacing.

Key Features

The PIC16LF628A-I/SS stands out for its low-power operation, with typical current consumption as low as 20 µA in sleep mode. Its flash memory supports in-circuit serial programming (ICSP), enabling easy firmware updates without removing the chip from the circuit. The microcontroller also includes hardware-based interrupts and a built-in voltage reference for analog applications. Other notable features include a wide temperature range (-40°C to +85°C), making it suitable for industrial environments. The device's small footprint and integration of peripherals reduce the need for external components, lowering system cost and complexity.

Application Areas

The PIC16LF628A-I/SS is widely used in embedded systems, such as home automation devices, sensor nodes, and small control units. Its low-power capabilities make it a popular choice for battery-operated products like remote controls, wearable devices, and portable medical instruments. In industrial settings, the microcontroller is employed in motor control, instrumentation, and monitoring systems. Its reliability and ease of integration also make it suitable for consumer electronics, including toys, small appliances, and LED lighting controllers.

Maintenance and Precautions

Proper handling of the PIC16LF628A-I/SS is essential to avoid electrostatic discharge (ESD) damage. Use grounded workstations and anti-static packaging during assembly and testing. Ensure the power supply voltage remains within the specified range to prevent malfunction or permanent damage. For firmware development, utilize Microchip's MPLAB X IDE and compatible programmers/debuggers. Regularly update development tools and firmware to leverage the latest features and bug fixes. Avoid exposing the device to extreme temperatures beyond its rated range.

B2B Procurement Guide

When sourcing the PIC16LF628A-I/SS, verify the supplier's authenticity to avoid counterfeit products. Microchip Technology or authorized distributors like Digi-Key, Mouser, and Arrow Electronics are reliable sources. Consider bulk purchasing for cost savings, but ensure proper storage to maintain component integrity. Evaluate lead times and minimum order quantities (MOQs) to align with production schedules. For prototyping or small batches, sample kits may be available. Check for compliance with industry standards and RoHS directives if environmental regulations apply to your application.
