W74M12JWZEIQ

The W74M12JWZEIQ is a 128 Mbit non-volatile NAND Flash device in the Winbond SpiFlash® family, organized as 16M × 8 and implemented with a SPI – Quad I/O interface. It combines high-density flash storage with on-die authentication features to support secure code and data storage in embedded systems.

Targeted at emerging IoT, mobile accessories, home automation and industrial control applications, the device delivers multi-layer authentication capabilities—including a hardware HMAC-SHA-256 crypto accelerator and monotonic flash counters—to strengthen integrity and resist replay or cloning attacks.

Key Features

• Memory — 128 Mbit NAND Flash organized as 16M × 8 for code and data storage in embedded systems.
• Security — Standard HMAC-SHA-256 crypto accelerator and four separate monotonic flash counters, each HMAC-signed by individual secret keys, enabling verification of integrity, authenticity and timestamping of stored values.
• Interface & Performance — SPI – Quad I/O memory interface with a clock frequency rating of 104 MHz for high-throughput serial access.
• Power — Low-voltage operation with a supply range of 1.7 V to 1.95 V, suitable for 1.8 V system domains.
• Package & Mounting — Available in an 8-WSON (8 × 6 mm) package with an exposed pad; listed package case: 8-WDFN exposed pad.
• Temperature Range — Industrial ambient range of −40 °C to 85 °C (TA) for use across typical embedded environments.

Typical Applications

• Emerging IoT — Adds multi-layer authentication and secure storage for connected sensors and devices to protect firmware and device identity.
• Mobile Accessories — Protects firmware and enables anti-cloning measures for accessories that require validated hardware/software provenance.
• Home Automation — Stores authenticated configuration and firmware updates to maintain system integrity in smart home controllers and modules.
• Industrial Control — Provides authenticated counters and secure storage for equipment that requires tamper resistance and validated events.
• Smart Home — Enables device-level root of trust and IP/software protection for consumer automation endpoints.

Unique Advantages

• Built-in cryptographic acceleration: On-die HMAC-SHA-256 hardware block simplifies implementation of authenticated storage and message signing.
• Monotonic flash counters: Four independent counters, each HMAC-signed by unique secret keys, enable tamper-resistant event logging and replay protection.
• Quad SPI performance: Quad I/O SPI interface at up to 104 MHz supports fast serial transfers for firmware and data operations.
• Low-voltage operation: 1.7 V to 1.95 V supply supports integration into 1.8 V system rails to minimize power domain complexity.
• Compact package: 8-WSON (8 × 6 mm) with exposed pad provides a small footprint and thermal path for PCB assembly.
• Designed for IoT authenticity: Feature set explicitly targets multi-layered authentication needs such as PCBA anti-copy, anti-cloning, IP/software protection and root-of-trust implementations.

Why Choose IC FLASH 128MBIT SPI/QUAD 8WSON?

The W74M12JWZEIQ positions secure flash storage and authentication primitives in a single compact SPI-Quad Flash device, enabling designers to add multi-layer authenticity without separate cryptographic components.
