ATTINY24A-MUR

Overview

The ATTINY24A-MUR is an 8-bit AVR microcontroller featuring 2KB of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 20MHz at 4.5V–5.5V. The device includes a 10-bit ADC with 8 single-ended channels, two PWM-capable timers, and a Universal Serial Interface. It utilizes a 20-pin QFN/MLF package and functions across industrial temperature ranges.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Non-volatile memory segments with high endurance for Flash and EEPROM
• Integrated analog-to-digital converter with programmable gain stages
• Multiple low-power operating modes including Idle and Power-down

Applications

• In-system programming via SPI interface
• Touch sensing applications using QTouch Library

• Battery-powered devices utilizing extended data retention

Procurement Notes

Verify the specific speed grade suffix against the required operating voltage and frequency constraints. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the industrial temperature rating matches the environmental specifications of the target application before finalizing procurement orders.

Selection Notes

Select this component when a compact 20-pin form factor is necessary alongside 2KB of program memory. Consider the ATTINY24A-MUR for designs requiring precise analog signal acquisition through its differential ADC pairs. Evaluate the trade-off between processing speed and power consumption based on the available sleep modes and static operation characteristics.

Part Context

This microcontroller belongs to the ATtiny family, which emphasizes low power and high performance. The device is manufactured using high-density non-volatile memory technology. It shares architectural similarities with other members like the ATtiny44A and ATtiny84A, differing primarily in memory capacities and specific pin configurations.

Replacement Considerations

Direct substitutes include ATTINY24A-MU and ATTINY24A-MMH. Verify pin compatibility and memory sizes when replacing with ATTINY44A or ATTINY84A variants.
