ATTINY48-MMH

Overview

The ATTINY48-MMH is an 8-bit AVR microcontroller featuring a high-performance RISC core with single-cycle instruction execution. It integrates 4K bytes of In-System Programmable Flash, 64 bytes of EEPROM, and 256 bytes of SRAM. The device supports a maximum clock frequency of 12 MHz at 4.5V to 5.5V, operating within a supply voltage range of 1.8V to 5.5V. It includes two flexible Timer/Counters, a 6-channel 10-bit ADC, SPI, and TWI interfaces. The component is housed in a 28-pad QFN package and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Advanced RISC architecture enabling near 1 MIPS per MHz throughput through single-clock cycle execution.
• High endurance non-volatile memory segments with 10,000 Flash write/erase cycles and 100,000 EEPROM cycles.
• Integrated peripheral features including debugWIRE on-chip debugging, programmable Watchdog Timer, and analog comparator.
• Three software-selectable power-saving modes: Idle, ADC Noise Reduction, and Power-Down.

Applications

• Embedded control systems requiring low-power operation
• Battery-powered portable devices
• Industrial monitoring applications

Procurement Notes

Verify the specific suffix MMH corresponds to the 28-pad QFN package variant when sourcing. Confirm that the procurement documentation explicitly references the ATtiny48/88 datasheet (Document Number 8008S) for electrical characteristics. Ensure compliance with RoHS directives as indicated in manufacturer specifications. Cross-reference ordering information with official Microchip Technology distributors to validate part authenticity.

Selection Notes

Select this model for designs requiring 4KB of program memory and 256 bytes of RAM in a compact surface-mount form factor. It is suitable for applications needing multiple I/O lines and analog-to-digital conversion capabilities without the complexity of larger MCU families. Consider the 12 MHz speed grade relative to the system's power budget and timing requirements.

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 capacity. The device utilizes Atmel's high-density non-volatile memory technology and is designed for cost-effective embedded solutions.

FAQ

What is the function of the PC6 pin?

PC6 serves as the RESET input. If the RSTDISBL fuse is programmed, it functions as a general-purpose I/O pin.

How does the device handle power consumption during sleep?

It offers three sleep modes: Idle stops the CPU while peripherals run; ADC Noise Reduction minimizes switching noise; Power-Down disables all chip functions except external interrupts or hardware resets.
