ATTINY48-MMHR

Overview

The ATTINY48-MMHR is an 8-bit AVR microcontroller featuring 4K bytes of in-system programmable Flash, 64 bytes of EEPROM, and 256 bytes of SRAM. It utilizes a high-performance RISC architecture with up to 1 MIPS throughput at 12 MHz. The device operates within a voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to +85°C. It includes two flexible timer/counters, a 6-channel 10-bit ADC, SPI, and I²C interfaces.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• High endurance non-volatile memory segments with data retention capabilities
• Integrated peripheral features including timers, ADC, and serial interfaces
• Multiple power-saving modes for optimized energy consumption

Applications

• Embedded control systems requiring low power operation
• Sensor nodes utilizing the integrated ADC and temperature sensor
• Industrial applications operating within extended temperature ranges
• Battery-powered devices leveraging multiple sleep modes

Procurement Notes

Verify the specific suffix MMHR corresponds to the required tape and reel packaging configuration. Confirm that the component meets all relevant environmental compliance standards for the intended deployment region. Ensure compatibility with existing design tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this model when 4KB Flash capacity suffices for application code requirements. Consider the 28-pin QFN package constraints regarding PCB layout and thermal dissipation. Evaluate if the 6-channel ADC resolution meets signal processing needs compared to higher channel count alternatives.

Part Context

This component belongs to the ATtiny48/88 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny88 but offers reduced memory resources. The device is designed for cost-sensitive embedded applications requiring reliable performance and low power consumption.

Replacement Considerations

ATtiny48-MU serves as a direct pin-compatible alternative in different package configurations.
