Product Description
The Microchip ATTINY404-SSN is a high-performance 8-bit AVR microcontroller engineered for embedded and general-purpose control applications. Designed in a 14-pin SOIC surface mount package, this microcontroller operates at frequencies up to 20MHz, delivering reliable and efficient processing power for a range of industrial and commercial scenarios.
With 4kB of onboard Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM, the ATTINY404 enables secure code storage and versatile data handling. Its AVR RISC architecture, combined with a hardware multiplier and a comprehensive set of 135 instructions, supports fast and flexible execution in embedded tasks. The device is equipped with 12 programmable I/O lines, ensuring compatibility for custom hardware configurations.
The ATTINY404 supports a broad operating voltage from 1.8V to 5.5V, making it adaptable in both modern low-power designs and traditional 5V systems. Multiple power management sleep modes such as idle, standby, and power-down help reduce consumption when processing demands are low. Key analog peripherals include 10-channel 10-bit ADCs with voltage reference, a comparator, as well as two 16-bit timers for precise timing and event management functionalities.
Robust safety features such as Power-On Reset (POR), Brown-Out Detection (BOD), a Watchdog Timer (WDT), and Cyclical Redundancy Check (CRC/SCAN) are built-in, ensuring consistent operation and data integrity. Programming and debugging are streamlined via a single-pin Unified Program and Debug Interface (UPDI), enhancing workflow efficiency for developers.
Physically, the component features a compact 8.74mm × 3.9mm × 1.5mm form factor, suitable for densely populated PCBs. It is compatible with industrial standards, including RoHS compliance, and operates across a temperature range from - 40°C to 125°C.
Common application areas include industrial controls, instrumentation, consumer electronics, and laboratory equipment, where reliable performance, programmable interfaces, and low power consumption are paramount.
Selecting the Microchip ATTINY404-SSN ensures access to a versatile, robust, and compact microcontroller ideally suited for demanding industrial, automation, and embedded electronic solutions.
