Overview
The ATTINY24A-MM8 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 one 8-bit and one 16-bit Timer/Counter with PWM channels, a 10-bit ADC with 8 single-ended channels, 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 for high throughput efficiency.
- Non-volatile memory segments including self-programmable Flash and EEPROM with high endurance ratings.
- Integrated peripheral set comprising dual timer/counters, a 10-bit ADC with programmable gain, and analog comparator.
- Supports multiple low-power operating modes including Idle, Standby, and Power-down to minimize energy consumption.
Applications
- In-system programming via SPI interface
- Touch sensing interfaces using QTouch Library
- Industrial control systems requiring robust non-volatile data storage
Procurement Notes
Verify the specific speed grade suffix corresponds to the required operating frequency and voltage conditions. Confirm the MM8 package designation matches the intended PCB footprint and thermal requirements. Ensure the component meets RoHS compliance standards if applicable to the manufacturing process. Cross-reference the ordering code with the manufacturer's current availability list to confirm active status.
Selection Notes
Select this model when a compact 20-pin form factor is required alongside 2KB of program memory. The MM8 suffix indicates a Very Thin Quad Flat No Lead package suitable for space-constrained designs. Consider the 20MHz speed grade only if the supply voltage remains within the 4.5V to 5.5V range. Evaluate power consumption needs against the available sleep modes for battery-operated applications.
Part Context
This component belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. The family shares similar core features but varies in memory capacity and pin counts. The ATtiny24A specifically offers 2KB Flash, distinguishing it from the higher-capacity variants while maintaining compatibility with standard AVR development tools and instruction sets.
