ATTINY824-SSFR

Overview

The ATTINY824-SSFR is an 8-bit microcontroller from the Microchip tinyAVR 2 family, housed in a 14-pin SOIC package. It features an AVR CPU with hardware multiplier operating at up to 20 MHz. The device includes 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. Key peripherals include a 12-bit differential ADC with PGA supporting up to 15 channels, three 16-bit timers/counters, USART, SPI, and TWI interfaces. It operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges.

Feature Summary

• Integrates a high-performance low-power AVR CPU with single-cycle I/O access and a two-cycle hardware multiplier.
• Includes a 12-bit differential Analog-to-Digital Converter (ADC) with Programmable Gain Amplifier (PGA) for accurate analog signal acquisition.
• Features an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL) with programmable Look-Up Tables.
• Supports flexible clock options including lockable internal oscillators and external crystal inputs, alongside multiple sleep modes for power optimization.

Applications

• Low-power sensor nodes requiring precise analog measurement
• Industrial control systems utilizing event-driven peripheral communication
• Battery-operated devices needing extended data retention and low standby current

Procurement Notes

Verify the specific suffix 'SSFR' corresponds to the 14-pin SOIC package and tape & reel packaging configuration. Confirm that the industrial temperature grade (-40°C to +125°C) aligns with your operational environment requirements. Ensure compatibility with the UPDI programming interface for development and production flashing.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is required without code modification. Choose this part if the design demands a 12-bit ADC with PGA and up to 15 input channels on a compact 14-pin footprint. Consider this MCU for applications needing robust analog capabilities combined with standard digital interfaces like USART and SPI.

Part Context

This device belongs to the tinyAVR 2 family, which offers pin and feature compatibility across variants. The ATTINY824 provides 8 KB of Flash, distinguishing it from the 4 KB ATtiny424 while sharing the same 14-pin package architecture. It serves as a scalable solution within the series, allowing horizontal or vertical migration based on memory and pin count needs.

Replacement Considerations

ATtiny424-SSFR: Lower Flash capacity (4 KB). ATtiny826-SSFR: Higher pin count (20-pin). ATtiny827-SSFR: Higher pin count (24-pin). Verify package dimensions and pinout compatibility before substitution.
