ATTINY2313-20MUR

Overview

The ATTINY2313-20MUR is an 8-bit AVR microcontroller featuring a 20-pad MLF package. It includes 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 20 MHz at a supply voltage range of 2.7 V to 5.5 V. It provides 18 programmable I/O lines and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• AVR high-performance RISC architecture with up to 20 MIPS throughput at 20 MHz
• In-system self-programmable Flash memory with data security lock bits
• Full-duplex USART and Universal Serial Interface (USI) for communication
• On-chip debugWIRE interface for single-wire debugging and programming

Applications

• Embedded control systems requiring low power consumption
• Industrial applications operating in extreme temperature environments
• Battery-powered devices utilizing multiple power-saving sleep modes
• General-purpose digital logic and signal processing tasks

Procurement Notes

Verify the specific speed grade suffix '20' corresponds to the required 20 MHz performance at the target operating voltage. Confirm that the 'U' suffix indicates the MLF package type and 'R' indicates tape and reel packaging. Ensure the component meets RoHS compliance requirements for your manufacturing process.

Selection Notes

Select this model when a 20 MHz operational speed is necessary alongside the specific 20-pad MLF form factor. Consider the 2.7 V minimum supply voltage requirement compared to the ATtiny2313V variant if lower voltage operation is needed. Evaluate the 18 available I/O lines against system pin count requirements.

Part Context

This component belongs to the ATtiny2313 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with other members like the ATtiny2313A but maintains distinct speed grades and package options. The MLF package offers a compact footprint suitable for space-constrained PCB designs.

Replacement Considerations

ATtiny2313-20MU serves as a direct tube-packaged alternative with identical electrical specifications.
