ATTINY2313-20PI

Overview

The ATTINY2313-20PI is an 8-bit AVR microcontroller manufactured by Microchip Technology, housed in a 20-pin PDIP package. It features 2K bytes of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates at speeds up to 20 MHz with a supply voltage range of 2.7V to 5.5V. Key peripherals include two Timer/Counters (one 8-bit, one 16-bit), four PWM channels, a full-duplex USART, a Universal Serial Interface (USI), and an on-chip Analog Comparator.

Feature Summary

• High-performance RISC architecture executing most instructions in a single clock cycle
• In-system self-programmable Flash memory for code updates via SPI
• Multiple power-saving modes including Idle, Power-down, and Standby
• On-chip debugging capability via the debugWIRE single-wire interface

Applications

• Embedded control systems requiring low pin count
• Battery-powered devices utilizing low-power sleep modes
• Simple serial communication interfaces using USART or USI
• Basic motor control applications leveraging PWM outputs

Procurement Notes

Verify the specific speed grade suffix matches the required operating frequency and voltage range. Confirm the package type corresponds to the intended PCB layout. Check current production status as older variants may be discontinued or not recommended for new designs. Ensure programming tools support the target revision level.

Selection Notes

Select this component when a cost-effective 8-bit solution with sufficient I/O lines and basic timers is needed. Consider the 20MHz maximum frequency limit for timing-critical tasks. Evaluate if the 128-byte RAM constraint fits application data requirements. Verify that the PDIP package is suitable for the manufacturing process.

Part Context

This part belongs to the ATtiny family of 8-bit AVR microcontrollers designed for performance and power efficiency. It shares architectural similarities with other members like the ATtiny4313 but offers distinct memory configurations. The PDIP variant provides through-hole mounting options suitable for prototyping and specific industrial enclosures.
