Overview

The PIC10F202 is an ultra-compact 8-bit microcontroller featuring a RISC architecture and a 4MHz internal oscillator. It is designed for simple, cost-sensitive control logic in applications where space is extremely limited, providing 768 bytes of program memory in a tiny 6-pin SOT-23 package.

Why Choose This Part

The primary advantage is its footprint-to-functionality ratio, offering a high-performance RISC CPU and internal oscillator in a 6-pin SOT-23 package. It operates over a wide voltage range of 2V to 5.5V and consumes as little as 100nA in sleep mode, making it ideal for battery-powered logic.

Applications

Simple Timing Circuits
Replacing discrete logic or 555 timers in delay-on or delay-off circuits.
Safety Interlocks
Implementing basic power-on reset (POR) or watchdog timer (WDT) monitoring for system safety.
Interface Level Shifting
Providing basic signal inversion or protocol translation between low-speed logic levels.
Input Debouncing
Managing mechanical switch inputs and providing clean digital outputs to a primary processor.
Status Indicators
Driving status LEDs with specific blink patterns or pulse-width modulation sequences.
