ATTINY804-SSFR

Overview

The ATTINY804-SSFR is an 8-bit AVR microcontroller from the tinyAVR 0-series, featuring a hardware multiplier and running at up to 20 MHz. It includes 8 KB of in-system self-programmable Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. The device operates within a voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to 125°C. Key peripherals include a 16-bit Timer/Counter Type A, a Real-Time Counter, USART, SPI, TWI, a 10-bit ADC, and an Analog Comparator. It utilizes a Single-Pin Unified Program and Debug Interface (UPDI) for programming.

Feature Summary

• Features a flexible low-power architecture with Core Independent Peripherals and an Event System for CPU-independent inter-peripheral signaling.
• Includes Configurable Custom Logic (CCL) with programmable look-up tables and automated CRC memory scan capabilities.
• Supports multiple sleep modes including Idle, Standby, and Power-Down with full data retention.
• Provides external interrupt capability on all general-purpose I/O pins.

Applications

• Industrial control systems requiring functional safety features
• Battery-powered devices utilizing low-power architecture
• Sensor interfaces using analog-to-digital conversion
• Communication nodes using serial protocols

Procurement Notes

Verify the specific suffix SSFR indicates tape and reel packaging when ordering. Confirm the industrial temperature grade (-40°C to 125°C) matches application requirements. Ensure the 14-SOIC package dimensions align with PCB layout constraints. Cross-reference the datasheet revision DS40002312A for any silicon errata or clarifications relevant to production.

Selection Notes

Select this component for applications needing a balance of processing speed and peripheral richness in a compact package. Consider the 20 MHz maximum clock speed and 8 KB program memory capacity against project demands. Evaluate the availability of specific peripherals like the 16-bit TCA or RTC if required by the design. Compare against other members of the tinyAVR 0-series for pin count and memory variations.

Part Context
