ATTINY2313A-MU

Overview

The ATTINY2313A-MU is an 8-bit AVR microcontroller featuring 2 KB of In-System Programmable Flash, 128 Bytes of EEPROM, and 128 Bytes of SRAM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes 18 programmable I/O lines, two Timer/Counters, a full-duplex USART, USI, and an on-chip analog comparator. It is housed in a 20-pad Very Thin Quad Flat No Lead (VQFN) package.

Feature Summary

• Advanced RISC architecture achieving up to 20 MIPS throughput at 20 MHz
• Supports low-power Idle, Power-down, and Standby modes
• Includes debugWIRE for single-wire on-chip debugging
• Features internal calibrated oscillator and programmable Brown-out Detection

Applications

• Battery-powered measurement systems
• Direct interface circuits without signal conditioning
• Embedded control applications requiring ISP programming

Procurement Notes

Verify the specific ordering suffix 'MU' corresponds to the 20-pad VQFN package with matte tin lead finish as defined in the manufacturer's ordering guide. Confirm that the industrial temperature range (-40°C to +85°C) meets the operational requirements of the target environment before finalizing procurement.

Selection Notes

Select this component when a compact 20-pin surface-mount solution is required for 8-bit processing tasks. The VQFN package offers thermal enhancement via an exposed pad. Ensure the design accommodates the 1.8 V to 5.5 V operating range and utilizes the available 18 I/O lines for system connectivity.

Part Context

This part belongs to the ATtiny2313A series within the Microchip AVR family. It shares architectural similarities with the ATtiny4313 but differs in memory capacity, offering 2 KB Flash compared to the 4 KB variant. The device is manufactured using high-density non-volatile memory technology compatible with standard SPI programming interfaces.

Replacement Considerations

Public confirmed substitute part numbers include ATTINY2313A-MMH.
