ATTINY24A-MF

Overview

The ATTINY24A-MF 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 4.5–5.5 V. The device includes a 10-bit ADC with eight 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 options
• Multiple low-power operating modes including idle and power-down

Applications

• In-system programming via SPI interface
• On-chip debugging using debugWIRE system
• Touch sensing applications supported by QTouch Library
• Industrial control systems requiring robust non-vatile storage

Procurement Notes

Verify the specific speed grade suffix corresponds to the required operational frequency for your target supply voltage. Confirm that the matte tin lead finish indicated by the 'F' suffix meets your soldering process requirements. Ensure the 20-pad QFN package dimensions align with your PCB footprint design guidelines before finalizing procurement orders.

Selection Notes

Select this component when a compact 8-bit solution with integrated analog features is required. The 20 MHz speed grade provides sufficient processing throughput for time-critical tasks while maintaining low power consumption. Consider the available I/O lines and timer configurations to ensure adequate peripheral support for the intended application logic without external components.

Part Context

This part belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. These devices are manufactured using high-density non-volatile memory technology. The family shares common core features but differs in memory capacities and pin counts to suit various embedded system constraints.
