Overview

The PIC16F1503-I/ST is a versatile 8-bit microcontroller from Microchip's Enhanced Mid-range family, featuring Functional Safety (FuSa) readiness in a compact 14-TSSOP package. Operating at up to 20MHz with 2KB of Flash, it integrates essential mixed-signal peripherals including an 8-channel 10-bit ADC and low-power management features. This MCU is optimized for cost-sensitive applications requiring efficient 1.8V to 5.5V operation and hardware-based safety monitoring.

Why Choose This Part

This microcontroller offers a high-endurance Flash memory for frequent data logging and a 16-level deep hardware stack for complex firmware execution. Its Core Independent Peripherals allow for reduced CPU overhead, while the wide operating voltage range simplifies power supply design in diverse environments.

Applications

Appliance Control
Small household appliances requiring basic logic, temperature monitoring via the integrated indicator, and PWM-based motor or heater control.
Industrial Safety Monitoring
Utilizes the Low-Power Brown-out Reset (LPBOR) and Extended Watchdog Timer (WDT) for reliable operation in functional safety environments.
Sensor Interface
Serves as a bridge for analog sensors using the 10-bit ADC and communicating results over I2C or SPI interfaces.
Portable Electronics
Benefit from low power consumption (30uA/MHz at 1.8V) and a small footprint for battery-operated handheld devices.
