ATTINY2313-20MU

Overview

The ATTINY2313-20MU is an 8-bit AVR microcontroller featuring a 20-pad QFN/MLF package. It includes 2K bytes of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports up to 20 MIPS throughput at 20 MHz with a supply voltage range of 2.7V to 5.5V. It provides 18 programmable I/O lines, two timers/counters, a full-duplex USART, USI, and an on-chip analog comparator.

Feature Summary

• AVR RISC architecture with single-clock-cycle execution for high efficiency
• In-system programmable non-volatile memory including Flash, EEPROM, and SRAM
• Integrated communication interfaces such as USART and Universal Serial Interface (USI)
• Multiple power-saving modes including Idle, Power-down, and Standby

Applications

• Embedded control systems requiring low power consumption
• Industrial applications operating within the industrial temperature range
• Battery-powered devices utilizing efficient sleep modes
• General-purpose digital logic replacement or expansion

Procurement Notes

Verify the specific speed grade suffix '20' indicates operation up to 20 MHz at 2.7V to 5.5V. Confirm the 'MU' suffix corresponds to the 20-pad QFN/MLF package type. Check current lifecycle status as older revisions may be marked Not Recommended for New Designs. Ensure compatibility with existing PCB footprints for the MLF package.

Selection Notes

Select this component when a small form factor is required due to the QFN/MLF packaging. Choose this part over PDIP or SOIC variants if surface mount density is a priority. Verify that the 2.7V minimum operating voltage meets system requirements, as lower voltage variants exist. Consider the 18 available I/O lines against application pin count needs.
