W74M12JWZPIQ TR

The W74M12JWZPIQ TR is a 128 Mbit non-volatile NAND flash memory device in Winbond's SpiFlash® family. It provides a 16M × 8 memory organization with a Quad I/O SPI interface and is built for authenticated storage and integrity protection using on-chip cryptographic features.

Designed for embedded and IoT applications that require multi-layer authentication and protection of code or data, the device combines HMAC-SHA-256 hardware acceleration and monotonic flash counters with a low-voltage 1.7 V–1.95 V operating range and a compact 8-lead package.

Key Features

• Security & Authentication — Integrated HMAC-SHA-256 crypto accelerator and four separate monotonic flash counters that are HMAC-signed by individual secret keys for message integrity and replay resistance.
• Memory — 128 Mbit NAND flash arranged as 16M × 8, providing non-volatile code and data storage with flash memory format.
• Interface — SPI Quad I/O memory interface supporting Quad SPI operation for higher throughput; specified clock frequency up to 104 MHz.
• Power — Low-voltage operation across a 1.7 V to 1.95 V supply range suitable for low-power embedded systems.
• Package — Available in compact 8-lead WSON (6 × 5 mm) package; package case referenced as 8-WDFN with exposed pad for thermal performance.
• Operating Range — Industrial-temperature operation from −40°C to 85°C (TA) for deployment in a wide range of environments.

Typical Applications

• Emerging IoT — Adds multi-layered authenticity to IoT devices by combining HMAC-SHA-256 and monotonic counters to protect firmware and telemetry against cloning and replay attacks.
• Mobile Accessories — Secure storage of keys and authentication data for accessory pairing and integrity checks in portable designs where low-voltage operation is required.
• Home Automation & Smart Home — Protects device identity and firmware integrity in home gateways, controllers, and modules that require authenticated updates and anti-cloning measures.
• Industrial Control — Provides authenticated code/data storage and monotonic counters for system-level protections in industrial modules and control electronics.

Unique Advantages

• Built-in Hardware Authentication: HMAC-SHA-256 accelerator enables on-chip cryptographic operations without relying on external processors.
• Monotonic Flash Counters: Four independent, HMAC-signed counters provide anti-replay and timestamping capability to strengthen message authenticity.
• Low-Voltage Operation: 1.7 V–1.95 V supply allows integration into low-power and battery-operated systems.
• Compact, Thermally-Supportive Package: 8-lead WSON (6×5 mm) with exposed pad aids thermal management in space-constrained PCBs.
• High-Speed SPI Interface: Quad I/O SPI with up to 104 MHz clock frequency supports faster flash access than standard single I/O modes.
• Established Manufacturer Support: Part of Winbond's SpiFlash® family with in-house wafer fabrication and product resources for design integration.
