ATTINY424-SSF

Overview

The ATtiny424-SSF is an 8-bit microcontroller from the Microchip tinyAVR 2 family, featuring a 14-pin SOIC package. It includes 4 KB of Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 12-bit ADC with PGA, two USARTs, SPI, TWI, and a Real-Time Counter.

Feature Summary

• Features a high-performance low-power AVR CPU with hardware multiplier and vectored interrupts.
• Includes a 12-bit differential ADC with Programmable Gain Amplifier (PGA) for accurate analog conversion.
• Supports flexible inter-peripheral signaling via an integrated Event System.
• Provides multiple sleep modes including Idle, Standby, and Power-Down for optimized power consumption.

Applications

• Battery-powered sensor nodes
• Industrial control systems
• Smart home appliances

Procurement Notes

Verify the specific ordering suffix 'SSF' corresponds to the SOIC-150 package and Tape & Reel carrier type as defined in the datasheet naming convention. Confirm that the temperature grade matches the required operational environment, as variants exist for industrial (-40°C to +85°C) and extended (-40°C to +125°C) ranges. Ensure compatibility with the UPDI programming interface requirements.

Selection Notes

Select this component when a compact 14-pin form factor is required alongside advanced analog capabilities like the PGA-equipped ADC. Consider the tinyAVR 2 family's vertical migration path if future upgrades to higher pin counts or memory sizes are anticipated without code modification. Evaluate the 20 MHz performance against the specific speed grades available at different supply voltages.

Part Context

This part belongs to the tinyAVR 2 family, which emphasizes low power and high performance in small packages. The ATtiny424 variant specifically offers 4 KB of Flash, suitable for applications requiring moderate program storage in a constrained footprint. It shares architectural similarities with other members of the series, facilitating development across the product line.
