ATTINY2313A-SU

Overview

The ATTINY2313A-SU is an 8-bit AVR microcontroller in a 20-lead SOIC package. It features 2 KBytes of In-System Programmable Flash, 128 Bytes of EEPROM, and 128 Bytes of SRAM. The device operates at up to 20 MHz with a supply voltage range of 1.8 V to 5.5 V. It includes 18 programmable I/O lines, two Timer/Counters, a full-duplex USART, USI, and debugWIRE support.

Feature Summary

• Advanced RISC architecture achieving nearly 1 MIPS per MHz throughput
• In-system self-programmable non-volatile memory for Flash and EEPROM
• Full-duplex USART and Universal Serial Interface (USI) for communication
• On-chip debugging via single-wire debugWIRE interface

Applications

• Embedded control systems requiring low power consumption
• Applications utilizing ISP programming via SPI port
• Systems needing serial communication through USART or USI
• Devices operating within industrial temperature ranges

Procurement Notes

Verify the specific suffix 'SU' corresponds to the 20-lead Small Outline Integrated Circuit (SOIC) package type. Confirm that the speed grade matches the required operational frequency for the target supply voltage. Ensure compliance with RoHS directives as indicated by the Pb-free manufacturing process. Check for any specific revision notes regarding errata or feature updates before finalizing procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for 8-bit processing tasks. The SOIC package offers a balance between pin count and board space efficiency. Consider the 20 MHz maximum clock speed against the available power budget. Verify that the 18 available I/O lines meet the peripheral connection requirements without necessitating external multiplexing.

Part Context

This part belongs to the ATtiny2313A family, which shares architectural similarities with the ATtiny4313 but differs in memory capacity. The ATtiny2313A specifically provides 2 KBytes of Flash compared to the 4 KBytes found in the ATtiny4313 variant. Both devices utilize the same enhanced RISC core and peripheral set, differing primarily in storage size.

Replacement Considerations

ATtiny2313A-MU: Identical electrical specifications and functionality, packaged in a 20-pad MLF format instead of SOIC.
