ATTINY4313-SU

Overview

The ATTINY4313-SU is an 8-bit AVR microcontroller in a 20-lead SOIC package. It features 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. The device operates at speeds up to 20 MHz with a supply voltage range of 1.8V to 5.5V. It includes 18 programmable I/O lines, two Timer/Counters, four PWM channels, a USART, USI, and an Analog Comparator.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• In-system self-programmable non-volatile memory with data security programming lock capabilities.
• Comprehensive peripheral set including dual timers, full-duplex USART, Universal Serial Interface, and analog comparator.
• Supports multiple low-power operating modes including Idle, Power-down, and Standby.

Applications

• Embedded control systems requiring in-system reprogrammability
• Battery-powered devices utilizing low-power consumption modes
• Serial communication interfaces using USART or USI protocols

Procurement Notes

Verify the ordering suffix 'SU' corresponds to the 20-lead Small Outline Integrated Circuit (SOIC) package configuration. Confirm the speed grade matches the required operational frequency and voltage constraints. Ensure compliance with industrial temperature range specifications if applicable to the deployment environment.

Selection Notes

Select this component when 4K Flash and 256-byte data memories are required compared to the smaller ATtiny2313A variant. Consider the 20-pin SOIC package for surface mount assembly requirements. Evaluate the 20 MHz maximum speed against system timing needs within the specified voltage ranges.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares core functionality with the ATtiny2313A but offers doubled memory capacities. The series is designed for cost-effective embedded control applications with flexible I/O and serial interface options.

Replacement Considerations

ATtiny4313-SUR provides the same functional specifications in a tape and reel packaging format instead of tube packaging.
