ATTINY24-20MUR

Overview

The ATTINY24-20MUR is an 8-bit AVR microcontroller featuring a 2 KB In-System Programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 2.7 V to 5.5 V. The device includes one 8-bit and one 16-bit Timer/Counter with PWM channels, an 8-channel 10-bit ADC, and a Universal Serial Interface. It utilizes a 20-pin QFN/MLF package (20M1) in tape and reel format.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory with high endurance ratings
• Integrated analog-to-digital converter with programmable gain stages
• Multiple software-selectable low-power sleep modes

Applications

• Industrial control systems requiring robust I/O handling
• Battery-powered embedded devices utilizing low power consumption modes
• Sensor interface applications leveraging the 10-bit ADC capabilities
• General-purpose logic replacement in cost-sensitive designs

Procurement Notes

Verify that the specific ordering code matches the required speed grade and voltage range for the target application environment. Confirm the package type corresponds to the PCB footprint specifications. Ensure compliance with RoHS directives if restricted substances are a constraint for the manufacturing process. Cross-reference the datasheet revision history for any known errata relevant to the silicon revision being procured.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required within a compact form factor. The 20 MHz speed grade supports higher throughput operations compared to lower speed variants. The industrial temperature range ensures reliability in demanding environmental conditions. Consider the available I/O lines and peripheral count against system requirements before finalizing the selection.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny44 and ATtiny84, differing primarily in memory capacity. The series is designed for applications needing efficient code execution and minimal external components.

Replacement Considerations

ATtiny24V-20MUR offers a wider voltage range starting from 1.8 V. ATtiny44-20MUR provides increased memory capacity while maintaining the same pinout and core features.
