ATTINY2313-20SI

Overview

The ATtiny2313-20SI is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 2K bytes of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 2.7V to 5.5V. It includes 18 programmable I/O lines, two Timer/Counters, a full-duplex USART, USI, and an analog comparator. The component is housed in a 20-pin SOIC package.

Feature Summary

• AVR high-performance RISC architecture with single-cycle execution
• In-system self-programmable Flash memory
• Full-duplex USART and Universal Serial Interface (USI)
• On-chip debugging via debugWIRE interface

Applications

• Embedded control systems
• Serial communication interfaces
• General-purpose I/O expansion

Procurement Notes

Verify the specific speed grade suffix '20' corresponds to the required 20 MHz operational frequency at the target supply voltage. Confirm the 'SI' suffix indicates the 20-lead Small Outline Integrated Circuit (SOIC) package type. Ensure the procurement specification matches the industrial temperature range requirements for the application environment.

Selection Notes

Select this component when a low-power 8-bit solution with integrated serial communication capabilities is required. The device supports both internal and external interrupt sources and offers multiple power-saving modes. Consider the available I/O count and memory size relative to the application's code and data storage needs before finalizing the selection.

Part Context

This part belongs to the ATtiny2313 family within the AVR microcontroller portfolio. It shares architectural similarities with other devices in the series but is distinguished by its specific memory configuration and package options. The device utilizes Atmel's high-density non-volatile memory technology for program and data storage.

Replacement Considerations

Public confirmed substitute part numbers include ATtiny2313-20SU and ATtiny2313-20SJ.
