ATTINY2313A-MUR

Overview

The ATTINY2313A-MUR 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 timers/counters, a full-duplex USART, and a Universal Serial Interface (USI). It is housed in a 20-pad MLF package (4 x 4 mm) with a matte tin lead finish and is supplied in tape and reel packaging.

Feature Summary

• Advanced RISC architecture achieving up to 20 MIPS throughput at 20 MHz
• Supports low-power Idle, Power-down, and Standby modes
• Includes on-chip debug capabilities via debugWIRE interface
• Features internal calibrated oscillator and programmable watchdog timer

Applications

• Embedded control systems requiring low power consumption
• Battery-operated devices utilizing multiple sleep modes
• Applications necessitating serial communication via USART or USI
• Industrial environments operating within the -40°C to +85°C temperature range

Procurement Notes

Verify that the specific ordering suffix 'R' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the matte tin lead finish specification aligns with soldering compatibility requirements. Ensure the MLF package dimensions match the intended PCB footprint design constraints.

Selection Notes

Select this component when a compact surface-mount solution is required for memory-constrained applications. The MLF package offers a small form factor suitable for space-limited designs. Consider the 20 MHz speed grade if higher processing throughput is needed compared to lower-speed variants.

Part Context

This part belongs to the ATtiny2313A series, which shares architectural similarities with the ATtiny4313 but differs in memory capacity. The series utilizes the high-density non-volatile memory technology from Microchip. It is designed as a cost-effective solution for embedded control tasks using the AVR enhanced RISC architecture.

Replacement Considerations

ATtiny2313A-MU serves as a tray-packaged alternative within the same package type.
