ATTINY2313A-PU

Overview

The ATTINY2313A-PU is an 8-bit AVR microcontroller in a 20-pin PDIP package. It features 2 kB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates at frequencies up to 20 MHz with supply voltages ranging from 1.8 V to 5.5 V. It includes two Timer/Counters, four PWM channels, a full-duplex USART, and a Universal Serial Interface (USI). The unit supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• In-system programmable non-volatile memory including Flash, EEPROM, and SRAM with data security lock bits.
• Integrated peripheral set featuring dual timer/counters, multiple PWM channels, and serial communication interfaces.

Applications

• Embedded control systems requiring low power consumption
• Industrial monitoring applications within specified temperature ranges
• General-purpose I/O expansion using available interrupt sources

Procurement Notes

Verify the specific ordering code against current Microchip documentation to ensure compatibility with required speed grades and voltage ranges. Confirm that the PDIP package type aligns with the target PCB footprint and assembly processes. Check for any recent product change notifications regarding lead finish or manufacturing site updates before finalizing procurement plans.

Selection Notes

Select this component when a cost-effective 8-bit solution with sufficient I/O lines and standard serial interfaces is required. Consider the ATtiny4313 if larger memory capacity is needed, as it shares the same pinout and feature set but offers increased storage. Ensure the design accommodates the 20-pin DIP form factor constraints.

Part Context

This part belongs to the ATtiny family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It utilizes the enhanced RISC architecture optimized for performance per watt. The device is designed for embedded applications where small size and low power are critical, offering a balance of processing capability and peripheral integration.
