ATTINY24A-SSFR

Overview

The ATTINY24A-SSFR 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 supply 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 14-pin SOIC package and functions across an industrial temperature range of -40°C to +125°C.

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.
• Multiple software-selectable power-saving modes including Idle, ADC Noise Reduction, Standby, and Power-down.

Applications

• In-system programming via SPI port
• On-chip debug system using debugWIRE
• Industrial temperature environment control

Procurement Notes

Verify the specific speed grade suffix corresponds to the required operating frequency for your target voltage. Confirm the SSFR designation indicates the tape and reel packaging format suitable for automated assembly processes. Ensure the industrial temperature rating aligns with your environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-pin-count solution with integrated non-volatile memory and analog capabilities is required. The 14-pin SOIC form factor suits space-constrained designs. Consider the trade-off between processing speed and power consumption based on the available sleep modes and static operation characteristics defined in the datasheet.

Part Context

This part belongs to the ATtiny24A/44A/84A family of low-power CMOS 8-bit microcontrollers. These devices are manufactured using high-density non-volatile memory technology and share a common core architecture. Variations within the family differ primarily in program memory size while maintaining similar peripheral sets and pin configurations.
