ATTINY24A-MU

Overview

The ATTINY24A-MU is an 8-bit AVR microcontroller featuring 2 KB of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates within a voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 20 MHz at the upper voltage limit. The device includes a 10-bit ADC with eight single-ended channels, two timer/counters with PWM capabilities, and a Universal Serial Interface. It utilizes a 20-pin Very Thin Quad Flat No Lead (VQFN) package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Non-volatile memory segments including self-programmable Flash and EEPROM with specified endurance ratings.
• Integrated analog peripherals comprising a 10-bit ADC with programmable gain and an on-chip analog comparator.
• Multiple low-power operating modes including Idle, ADC Noise Reduction, Standby, and Power-down.

Applications

• In-system programming via SPI interface
• Touch sensing interfaces using QTouch Library
• Industrial temperature range monitoring

Procurement Notes

Verify the specific speed grade suffix against the required operating voltage and temperature range. Confirm the package type matches the design footprint. Ensure compliance with RoHS directives as indicated in ordering information. Check for tape and reel availability if automated assembly is required. Validate that the manufacturing data aligns with project timelines.

Selection Notes

Select this component when a compact 8-bit solution with integrated analog conversion is needed. The VQFN package suits space-constrained designs. Consider the 20 MHz speed capability relative to the supply voltage constraints. Evaluate power consumption requirements across different sleep modes. Ensure development tools support the AVR instruction set.

Part Context

This part belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers. These devices share a common enhanced RISC core and peripheral set, differing primarily in memory sizes. The ATTINY24A variant specifically provides 2 KB of Flash memory. The family supports industrial temperature ranges and offers multiple package options for diverse form factors.
