ATTINY24A-SSF

Overview

The ATTINY24A-SSF 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 at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes one 8-bit and one 16-bit Timer/Counter with two PWM channels each, a 10-bit ADC with eight single-ended channels, and a Universal Serial Interface. It utilizes a 14-pin SOIC package and supports 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 specified endurance ratings.
• Integrated peripheral set comprising dual timer/counters, a 10-bit analog-to-digital converter, and a Universal Serial Interface.
• Supports multiple low-power operating modes including Idle, ADC Noise Reduction, Standby, and Power-down.

Applications

• In-system programming via SPI interface
• On-chip debug system using debugWIRE
• Pin change interrupt handling on available I/O lines

Procurement Notes

Verify the specific speed grade suffix corresponds to the required operational frequency at your target supply voltage. Confirm that the SSF suffix indicates the correct industrial temperature rating and matte tin lead finish. Ensure the ordering code matches the exact package dimensions and pinout configuration required for your PCB layout design.

Selection Notes

Select this component when a compact 8-bit solution with moderate program memory and integrated analog conversion is required. The device offers a balance of processing speed and power consumption suitable for battery-operated systems. Consider the availability of internal oscillators and programmable watchdog timers for simplified circuit designs 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. The family shares common core features but differs in memory sizes and pin counts. The ATTINY24A specifically provides 2 KB of Flash memory, positioning it as a cost-effective option for applications requiring basic control logic and limited data storage capabilities.
