ATTINY4313-MU

Overview

The ATTINY4313-MU is an 8-bit AVR microcontroller featuring a 20-pad MLF/VQFN package. It includes 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. The device supports up to 20 MIPS throughput at 20 MHz with operating voltages from 1.8V to 5.5V. It provides 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 efficiency
• In-system self-programmable non-volatile memory with data security lock bits
• Integrated debugWIRE on-chip debugging and SPI programming interface
• Multiple software-selectable low-power sleep modes including Idle and Power-down

Applications

• Embedded control systems requiring low power consumption
• Industrial applications within the specified temperature range
• Battery-powered devices utilizing multiple sleep modes
• Systems needing serial communication via USART or USI

Procurement Notes

Verify the specific ordering suffix corresponds to the required package type and lead finish. Confirm that the speed grade matches the intended supply voltage and operational frequency requirements. Ensure compliance with RoHS directives and check for any specific handling precautions related to the MLF/VQFN package during assembly.

Selection Notes

Select this component when 4K bytes of program memory are necessary compared to the 2K byte variant. Consider the MLF/VQFN package for surface mount applications requiring a compact footprint. Evaluate the 1.8V to 5.5V operating range against system power constraints and verify that the 18 available I/O lines meet interface requirements.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares peripheral features with the ATtiny2313A but offers double the memory capacity. The family is designed for cost-effective embedded control solutions with high code efficiency and low power consumption.

Replacement Considerations

ATtiny4313-MMH serves as a direct substitute offering the same specifications in a VQFN package.
