ATTINY48-MU

Overview

The ATTINY48-MU is an 8-bit AVR microcontroller manufactured by Microchip Technology, housed in a 32-lead Thin Quad Flat Package (TQFP). It features 4K bytes of In-System Programmable Flash, 64 bytes of EEPROM, and 256 bytes of SRAM. The device operates on a supply voltage ranging from 1.8V to 5.5V and supports clock frequencies up to 12MHz at the upper voltage limit. It includes 28 programmable I/O lines, two timer/counters, a 6-channel 10-bit ADC, and standard serial interfaces.

Feature Summary

• Advanced RISC architecture with single-clock-cycle execution for high throughput
• In-system self-programmable flash memory with software security lock bits
• Integrated debugWIRE system for on-chip debugging via SPI port
• Multiple power-saving modes including Idle, ADC Noise Reduction, and Power-Down

Applications

• Embedded control systems requiring low power consumption
• Industrial applications utilizing the industrial temperature range
• Battery-powered devices leveraging extended data retention capabilities
• Smart energy and sensor interface modules

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 32-lead TQFP configuration. Confirm that the selected revision matches the required firmware development tools and programming interface specifications.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required within a compact surface-mount package. Consider the ATtiny48 over the ATtiny88 if the application requires less program memory but maintains identical peripheral sets. Evaluate the 12MHz speed grade against the operating voltage requirements to ensure stable performance across the intended environmental conditions.

Part Context

This part belongs to the ATtiny48/88 family of 8-bit AVR microcontrollers based on enhanced RISC architecture. The series is designed for cost-effective embedded solutions, offering high endurance non-volatile memory segments and flexible peripheral options. It shares core architectural features with other members of the tinyAVR family while differing primarily in memory capacities and pin counts.

Replacement Considerations

Direct substitutes include the ATtiny48-MU variant with identical specifications. Cross-referencing with the ATtiny88-MU is possible if additional memory resources are needed without changing the physical footprint.
