ATTINY24A-MM8R

Overview

The ATTINY24A-MM8R 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 speeds up to 20MHz at 4.5V–5.5V. The device includes one 8-bit and one 16-bit Timer/Counter with PWM channels, a 10-bit ADC with programmable gain, and a Universal Serial Interface. It utilizes a 20-pin VQFN package and functions across industrial temperature ranges.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• High endurance non-volatile memory segments for program and data storage
• Integrated analog-to-digital converter with differential channel pairs and programmable gain
• On-chip debug system supporting in-system programming via SPI

Applications

• In-system programmable logic control
• Analog signal acquisition using the 10-bit ADC
• PWM-based motor or lighting control applications
• Serial communication interfaces utilizing USI

Procurement Notes

Verify the specific speed grade suffix against the required operating voltage and temperature range. Confirm the MM8R suffix corresponds to the 20-pin VQFN tape and reel packaging format. Ensure the ordering code matches the intended industrial temperature specifications before finalizing procurement.

Selection Notes

Select this component when a compact 20-pin form factor is required alongside 2KB of program memory. The VQFN package suits space-constrained designs. Consider the 20MHz maximum frequency capability at higher supply voltages for performance requirements. Verify that the 128-byte RAM allocation meets application stack and variable needs.
