ATTINY2313-20SUR

Overview

The ATTINY2313-20SUR is an 8-bit AVR microcontroller featuring a 20-pin SOIC package with tape and reel packaging. 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 integrates peripherals such as two Timer/Counters, a full-duplex USART, USI, and an analog comparator.

Feature Summary

• AVR RISC architecture delivering up to 20 MIPS throughput at 20 MHz
• In-system self-programmable Flash memory with high endurance
• Full-duplex USART and Universal Serial Interface (USI) for communication
• Low-power operation with Idle, Power-down, and Standby modes

Applications

• Embedded control systems requiring serial communication
• Battery-powered devices utilizing low-power sleep modes
• Industrial applications operating within the industrial temperature range
• Systems requiring in-circuit debugging via debugWIRE

Procurement Notes

Verify the specific suffix 'SUR' indicates tape and reel packaging on the official Microchip ordering guide. Confirm the speed grade corresponds to the 20 MHz variant operating between 2.7 V and 5.5 V. Ensure the component meets RoHS compliance requirements if specified for the project. Check for any end-of-life or not recommended for new design notices associated with this specific revision.

Selection Notes

Select this model when a 20 MHz processing speed is required at voltages starting from 2.7 V. Choose the SUR package variant specifically for automated surface-mount assembly processes requiring tape and reel delivery. Consider the ATtiny2313V series if operation at lower voltages down to 1.8 V is necessary, noting the reduced maximum speed limits for that variant.

Part Context

This component belongs to the ATtiny2313 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares the core architecture with variants like the ATtiny2313A but differs in speed grades and packaging options. The family is designed for cost-effective embedded control applications using the enhanced RISC architecture.

Replacement Considerations

ATtiny2313-20SU is the same electrical specification in tube packaging. ATtiny2313-20MU offers the same performance in MLF packaging.
