ATTINY404-SSF

Overview

The ATTINY404-SSF is an 8-bit AVR microcontroller from the tinyAVR 0-Series family, manufactured by Microchip Technology. It features a 20 MHz CPU, 4 KB of In-system self-programmable Flash memory, 256 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 clock speeds up to 20 MHz depending on the supply voltage. It includes a 10-bit ADC with 115 ksps sampling rate, multiple timers (TCA, TCB, RTC), communication interfaces (USART, SPI, TWI), and Configurable Custom Logic (CCL). The component is housed in a 14-pin SOIC package and supports industrial temperature ranges.

Feature Summary

• Integrates Core Independent Peripherals including Event System and SleepWalking for low-power operation
• Features a Single Pin Unified Program Debug Interface (UPDI) for programming and debugging
• Includes advanced analog capabilities such as a 10-bit ADC and five selectable internal voltage references
• Supports flexible clock options with high-accuracy internal oscillators

Applications

• Low-power sensor nodes utilizing sleep modes
• Industrial control systems requiring robust I/O and communication
• Battery-operated devices leveraging picoPower technology
• Applications necessitating precise timing via Real-Time Counter

Procurement Notes

Verify the specific suffix 'SSF' against official Microchip documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the required operating voltage and clock speed specifications for your application environment. Cross-reference the datasheet revision to confirm current availability and any potential design-in notices.

Selection Notes

Select this model when 4 KB of Flash and 256 bytes of SRAM are required within a 14-pin footprint. Consider the ATTINY404-SSF over the ATTINY204 variant if larger memory capacity is needed. Evaluate the need for industrial temperature ratings and specific package constraints before finalizing the part number selection.

Part Context

This component belongs to the ATtiny204/404 series within the tinyAVR 0-Series family. It shares architectural similarities with other members like the ATTINY414 but offers distinct memory configurations and peripheral sets tailored for cost-sensitive, space-constrained embedded applications.

Replacement Considerations

Consult official substitution lists for direct replacements. Verify pinout and electrical characteristics match before integrating alternative components.
