ATTINY4313-MMHR

Overview

The ATTINY4313-MMHR is an 8-bit AVR microcontroller featuring a 20-pad VQFN package. It includes 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 supports industrial temperatures from -40°C to +85°C and offers low-power consumption modes.

Feature Summary

• Advanced RISC architecture achieving up to 20 MIPS throughput at 20 MHz
• On-chip debugging via debugWIRE interface
• Flexible timer/counters with four PWM channels
• Universal Serial Interface (USI) and full-duplex USART

Applications

• Embedded control systems requiring in-system programming
• Low-power applications utilizing idle or power-down modes
• Industrial environments operating within the specified temperature range

Procurement Notes

Verify the specific ordering suffix MMHR corresponds to the required tape and reel packaging configuration. Confirm that the NiPdAu lead finish meets your assembly process requirements. Ensure the component matches the industrial temperature grade specifications for your intended operational environment.

Selection Notes

Select this model when 4K bytes of program memory are necessary, distinguishing it from the 2K byte ATtiny2313A variant. Consider the VQFN package dimensions for PCB layout constraints. Evaluate the 20 MHz speed grade against the available supply voltage levels to ensure stable operation.

Part Context

This component belongs to the ATtiny family based on the AVR enhanced RISC architecture. It shares pinouts and peripheral features with the ATtiny2313A but provides double the memory capacity. The device integrates non-volatile memory technologies allowing for flexible reprogramming capabilities.

Replacement Considerations

ATtiny4313-MMH serves as a direct alternative differing only in lead finish specification.
