ATTINY404 in ATtiny Family
The ATTINY404 is a member of the tinyAVR 0-series from Microchip Technology, featuring the 8-bit AVR processor with hardware multiplier. Operating at up to 20MHz, this sub-family is designed for high-performance, low-power applications where physical footprint and cost are critical constraints. It integrates flexible peripheral intelligence through the Event System, allowing inter-peripheral communication without CPU intervention, which significantly enhances deterministic response times and power efficiency in compact embedded systems.
Variants in This Sub-Family
Variants within the ATTINY404 sub-family primarily differ by temperature grade and qualification standards. Standard industrial-grade parts support -40C to 85C, while extended-range and automotive-qualified versions (AEC-Q100) are available for harsher environments. Package options typically center on the 14-pin SOIC and TSSOP footprints. While the core 4KB Flash and 256B SRAM remain constant across this specific sub-family number, ordering codes dictate factory-programmed configurations or specialized testing for functional safety compliance.
