The Puya PY25Q256HB‑Auto is a 256 Mbit (32 MB) automotive-grade serial NOR flash memory developed for high-reliability systems found in modern vehicles and industrial equipment. Compliant with AEC‑Q100 Grade 2, it operates across an extended temperature range of –40 °C to +125 °C, ensuring stable performance in harsh environments.

Featuring support for SPI, Dual I/O, and Quad I/O interfaces, the device offers rapid data throughput with clock speeds up to 133 MHz—essential for performance-critical applications like ECUs, ADAS, infotainment, and gateway modules. Operating at 2.7 V–3.6 V, it aligns seamlessly with standard automotive voltage rails.

To ensure long-term reliability, it delivers 100,000 program/erase cycles, 5-year data retention, and comprehensive protection with block lock, software/hardware write protection, and a physical /WP pin. Its deep power-down mode reduces standby current, optimizing energy efficiency even in large-scale flash systems.

The chip is available in compact SOP‑16 and WSON8 packages tailored for automotive PCB layouts, providing flexibility and ease of integration.
