ATTINY824-SSU

Overview

The ATTINY824-SSU is an 8-bit AVR microcontroller from the tinyAVR 2 family, housed in a 14-pin SOIC package. It features 8 KB of Flash memory, 1 KB of SRAM, and 128 B 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. It includes a 12-bit ADC with up to 15 channels, three 16-bit timers/counters, two USARTs, SPI, and TWI interfaces. The industrial temperature grade covers -40°C to +85°C.

Feature Summary

• Features a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access.
• 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 versatile communication options including dual USARTs, SPI, and TWI with multiple speed modes.

Applications

• Industrial control systems requiring robust peripheral integration
• Battery-powered devices utilizing low-power architecture
• Sensor interface modules using differential ADC capabilities
• General-purpose embedded applications within the tinyAVR 2 ecosystem

Procurement Notes

Verify the specific suffix 'SSU' corresponds to the 14-pin SOIC package and the -40°C to +85°C industrial temperature range. Confirm that the ordering information matches the official Microchip datasheet DS40002311A. Ensure compatibility with existing designs by checking pinout alignment with other members of the tinyAVR 2 family.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is required without code modification. Consider the 14-pin form factor if space is limited compared to 20 or 24-pin variants. Evaluate the 12-bit ADC resolution against simpler 10-bit alternatives if higher precision is necessary for signal conditioning tasks.

Part Context

This device belongs to the tinyAVR 2 family, which offers full pin and feature compatibility across different memory sizes. The ATTINY824 provides a balance of processing power and memory capacity suitable for mid-range applications. It shares architectural similarities with the ATtiny424 and ATtiny826/827 series.

Replacement Considerations

ATtiny424-SSU: Lower Flash capacity (4 KB). ATtiny826-SSUR: Higher pin count (20-pin SOIC). ATtiny824-MU: Different package type (VQFN).
