W74M25JVZEIQ TR

The W74M25JVZEIQ TR is a 256 Mbit non-volatile NAND Flash device in the Winbond W74M Authentication Flash family. It combines Flash storage (32M × 8 organization) with integrated authentication primitives to strengthen code and data integrity in connected devices.

Designed for applications requiring multi-layer authenticity and anti-cloning measures, the device targets emerging IoT, mobile accessories, home automation, industrial control and smart home systems by providing on-chip authentication capabilities alongside standard SPI/Quad I/O memory access.

Key Features

• Security Engine  Includes a standard HMAC-SHA-256 crypto accelerator and 4 separate Monotonic Flash Counters that are HMAC-signed by individual secret keys, enabling multi-layer authentication and resistance to replay attacks.
• Memory  256 Mbit FLASH - NAND organized as 32M × 8, suitable for authentication data, code protection and secure storage.
• Interfaces  Supports SPI with Quad I/O, QPI and DTR modes for flexible host interfacing and higher throughput options.
• Performance  Clock frequency up to 80 MHz with an access time of 6 ns for responsive flash access under supported interface modes.
• Power  Operates from a 2.7 V to 3.6 V supply range, compatible with common 3 V system rails.
• Package  Available in an 8-lead WDFN with exposed pad (listed as 8-WSON, 8×6 mm supplier package), providing a compact footprint for space-constrained PCBA layouts.
• Operating Range  Specified for an ambient temperature range of −40 °C to 85 °C (TA).

Typical Applications

• Emerging IoT  Adds multi-layered device authentication and secure storage for connected sensors, gateways and edge modules requiring protection against cloning and replay attacks.
• Mobile Accessories  Secures firmware and accessory identity with on-chip HMAC-SHA-256 and monotonic counters to prevent unauthorized duplication of modules.
• Home Automation & Smart Home  Provides authenticated storage for device credentials and firmware integrity checks in smart locks, controllers and sensors.
• Industrial Control  Stores secure boot or configuration data with authenticated counters and flash-based non-volatile memory for control modules operating across a wide temperature range.
• IP and Module Protection  Supports PCBA anti-copy and anti-cloning use cases by combining non-volatile storage with on-chip authentication primitives.

Unique Advantages

• Built-in Authentication Engine: Provides a standard HMAC-SHA-256 crypto accelerator on-chip for authenticated operations without adding external cryptographic hardware.
• Monotonic Counters for Replay Resistance: Four HMAC-signed monotonic flash counters enable integrity checks and timestamping with resistance to replay attacks.
• Flexible High-Speed Interfaces: Quad I/O, QPI and DTR support with up to 80 MHz clock frequency offers designers multiple interface modes for performance tuning.
• Compact, Board-Level Friendly Package: Supplied in an 8-lead exposed-pad WDFN/WSON (8×6 mm) package for small form-factor designs requiring secure non-volatile storage.
• Wide Supply and Temperature Range: Operates from 2.7 V to 3.6 V and −40 °C to 85 °C, allowing integration into a broad set of 3 V systems and ambient environments.
• Backed by Memory Expertise: Part of Winbond’s W74M product family and supported by Winbond’s manufacturing and memory design capabilities as described in the product brief.
