ATTINY2313A-MMH

Overview

The ATTINY2313A-MMH is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 2 KBytes of In-System Programmable Flash, 128 Bytes of EEPROM, and 128 Bytes of internal SRAM. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. It includes 18 programmable I/O lines, two Timer/Counters, a full-duplex USART, and a Universal Serial Interface (USI). The component is housed in a 20-pad Very Thin Quad Flat No Lead Package (VQFN) with dimensions of 3 x 3 mm.

Feature Summary

• Advanced RISC architecture achieving up to 20 MIPS throughput at 20 MHz with most instructions executing in a single clock cycle.
• Integrated non-volatile memory including self-programmable Flash, EEPROM, and SRAM for data retention and program storage.
• Comprehensive peripheral set featuring dual Timer/Counters, four PWM channels, an analog comparator, and debugWIRE on-chip debugging.
• Supports multiple low-power operating modes including Idle, Power-down, and Standby to optimize energy consumption.

Applications

• Embedded control systems requiring compact form factors
• Battery-powered devices utilizing low-power sleep modes
• Industrial monitoring applications within industrial temperature ranges
• Communication interfaces using USART or USI protocols

Procurement Notes

Verify the specific ordering suffix MMHR if tape and reel packaging is required, as MMH typically denotes tube packaging. Confirm RoHS compliance and lead finish specifications (NiPdAu) against current datasheet revisions. Ensure design compatibility with the 20-pad VQFN footprint and exposed pad soldering requirements. Check for any obsolete status notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a balance of processing speed and power efficiency is needed in a small package. The 20 MHz speed grade supports operation across the full 1.8 V to 5.5 V voltage range. Consider the ATtiny4313 if larger memory capacity is required, as it shares the same pinout and peripherals but offers increased Flash and RAM sizes. Verify that the 18 available I/O lines meet the interface requirements.

Part Context

This part belongs to the ATtiny2313A family, which shares architectural similarities with the ATtiny4313. The primary distinction lies in memory size, with the ATtiny2313A offering 2 KB Flash compared to the 4 KB in the ATtiny4313. Both devices utilize the same 20-pin packages and peripheral configurations, allowing for potential pin-compatible upgrades in designs requiring more storage space.

Replacement Considerations

ATtiny2313A-MMHR serves as the tape and reel variant of this component. ATtiny4313-MMH provides a pin-compatible upgrade with doubled memory resources while maintaining identical peripheral sets and package dimensions.
