MCHPATTINY2313-20PU
Microchip Technology
AVR AVR® ATtiny Microcontroller IC 8-Bit 20MHz 2KB (1K x 16) FLASH 20-PDIP
NRND24,461 in stock
Overview
The ATTINY2313-20PU is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 2KB of flash memory and 128 bytes of EEPROM. Its 20-pin PDIP package makes it a staple for through-hole prototyping and legacy system maintenance where a high I/O-to-memory ratio is required.
Why Choose This Part
The 20-pin PDIP form factor is ideal for rapid breadboarding and socketed applications. It offers a robust set of peripherals, including a hardware USART and an analog comparator, despite its small 2KB flash footprint.
Applications
Legacy System Retrofitting
Replacing discontinued or older 8051-style microcontrollers in existing through-hole PCB designs.
Interface Bridging
Utilizing the full-duplex USART and USI for translating data between different serial communication protocols.
Educational Prototyping
Serving as an accessible entry point for learning register-level AVR programming on breadboards without surface-mount soldering.
Simple Motor Controllers
Managing small DC motors or servos using its onboard timers and PWM capabilities in space-constrained enclosures.
