Overview

The PIC16LF1503-I/SL is an 8-bit microcontroller designed for extremely low-power operation, featuring 3.5KB of Flash memory and a 20MHz clock speed. This 'LF' variant is optimized for low-voltage applications, drawing as little as 30 uA/MHz at 1.8V. It integrates essential peripherals like a 10-bit ADC and multiple PWM channels into a compact 14-pin SOIC package.

Why Choose This Part

The component offers an excellent balance of cost and power efficiency, featuring a factory-calibrated internal oscillator and automatic context saving for interrupts. Its 'eXtreme Low Power' (XLP) characteristics make it ideal for systems where standby current must be minimized, while the self-programmable Flash allows for field firmware updates.

Applications

Battery-Powered Handheld Devices
Utilizes the ultra-low power consumption and wide voltage range for extended life in portable tools and instruments.
Household Sensor Nodes
Acts as a primary controller for environmental sensors, utilizing the 8-channel 10-bit ADC for analog data collection.
PWM Power Control
Manages simple motor control or LED dimming using integrated PWM peripherals and the 20MHz internal oscillator.
Signal Conditioning
Provides basic logic and threshold monitoring for analog signals in industrial system front-ends.

Getting Started

Development is supported by the Microchip MPLAB X IDE and the XC8 C Compiler. For hardware debugging and programming, use an MPLAB PICkit 4 or Snap in-circuit debugger via the two-pin ICSP interface. The 14-pin SOIC footprint is breadboard-friendly when used with a standard DIP adapter or small breakout board.

Also Consider

ATtiny404 MCHPMicrochip Technology - Offers a modern AVR core with 4KB Flash and more flexible peripheral routing in a similar 14-pin package.
PIC16F1503-I/SL MCHPMicrochip Technology - Standard 'F' version for applications requiring a higher operating voltage range up to 5.5V instead of the LF version's lower limits.
