ATTINY804-SSNR

Overview

The ATTINY804-SSNR is an 8-bit AVR microcontroller from the tinyAVR 0-series, manufactured by Microchip Technology. It features a single-cycle CPU with hardware multiplier running at up to 20 MHz. The device includes 8 KB of in-system self-programmable Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. It operates within a voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges. The component is housed in a 14-pin SOIC package.

Feature Summary

• Integrates a flexible low-power architecture with Core Independent Peripherals (CIPs) for predictable inter-peripheral signaling via the Event System.
• Includes multiple analog peripherals such as a 10-bit ADC, Analog Comparator, and multiple voltage references for accurate signal processing.
• Supports automated CRC memory scan and Configurable Custom Logic (CCL) to reduce CPU load and enhance system reliability.

Applications

• Industrial control systems requiring reliable data integrity checks
• Battery-powered devices utilizing low-power sleep modes
• Sensor interfaces using analog-to-digital conversion

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the procurement channel provides original manufacturer documentation. Ensure compliance with RoHS directives if applicable to your manufacturing process. Check for any specific handling requirements related to moisture sensitivity levels.

Selection Notes

Select this model when a balance of moderate program memory and high-speed processing is needed in a compact form factor. Consider the availability of the Single-Pin Unified Program and Debug Interface (UPDI) for simplified development. Evaluate the peripheral count against application requirements to ensure optimal pin utilization without unnecessary complexity.

Part Context

This component belongs to the tinyAVR 0-series family, designed for applications needing efficient code execution and low power consumption. It shares architectural similarities with other members like the ATtiny806 and ATtiny807 but differs in memory size and package options. The series emphasizes ease of use through the UPDI interface and advanced peripheral integration.

Replacement Considerations

Direct substitutes within the same package and pinout include the ATtiny804-SSU or ATtiny804-MHU. Verify compatibility regarding speed grades and operating voltage ranges before substitution.
