ATTINY404 in Microchip tinyAVR Family
The ATTINY404 is a member of Microchip Technology's tinyAVR 0-series, an 8-bit microcontroller family designed to bridge the gap between traditional low-pin-count MCUs and high-performance AVR devices. Utilizing the AVR RISC architecture, these chips operate at up to 20MHz and are optimized for low power consumption and deterministic execution. They are commonly employed in cost-sensitive industrial, automotive, and consumer applications where flexible peripheral sets and functional safety features are required in a compact 14-pin footprint.
Variants in This Sub-Family
Variants within the ATTINY404 sub-family primarily differ based on their temperature ratings and packaging options. Common packages include the 14-pin SOIC and TSSOP formats. Ordering codes such as 'SSNR' indicate specific temperature grades (e.g., -40 to +105 Celsius) and tape-and-reel packaging specifications. While the core 4KB Flash and 256B SRAM memory configuration remains consistent across this specific model, certain variants are qualified for automotive applications under the AEC-Q100 standard.
