W74M12FVSSIQ TR

The W74M12FVSSIQ TR is a 128 Mbit serial NAND Flash memory device in Winbond's SpiFlash® family. It provides serial SPI and Dual/Quad I/O SPI interface options and includes on-device secure authentication functionality.

Designed for space- and pin-constrained systems, the device supports code shadowing to RAM, execute-in-place (Dual/Quad SPI XIP), and general storage of voice, text and data while operating from a single 2.7 V to 3.6 V supply.

Key Features

• Memory — 128 Mbit FLASH (organized as 16M × 8) using NAND FLASH technology for non-volatile code and data storage.
• Interface — Standard SPI with Dual and Quad I/O SPI options (Serial Clock, Chip Select, I/O0–I/O3) for expanded throughput on supported read instructions.
• Performance — Product specification lists a clock frequency of 80 MHz; the datasheet references SPI clock operation up to 104 MHz for fast Dual/Quad I/O read modes.
• Security & Authentication — Built-in authentication flash operations including root key register write, HMAC key update, monotonic counter operations and an authentication status/data read path; three 256-byte security registers are provided.
• Device Identification & Standards — Supports JEDEC standard manufacturer/device ID and SFDP register, plus a 64-bit unique serial number for device traceability.
• Power — Single-supply operation from 2.7 V to 3.6 V for compatibility with common 3V systems.
• Package & Temperature — Available in an 8-pin SOIC (0.209", 5.30 mm width) package; specified operating temperature range is −40°C to 85°C (TA).

Typical Applications

• Embedded firmware storage — Serial Flash density and SPI/Quad I/O support code shadowing and storage of firmware images for microcontroller-based systems.
• Execute-in-place (XIP) — Dual/Quad SPI read modes enable executing code directly from flash where system architectures support XIP.
• Data and multimedia storage — Suitable for storing voice, text and other data in space-constrained products needing non-volatile storage.
• Secure authentication and key storage — On-device authentication operations, HMAC key handling and monotonic counter support provide mechanisms for secure device authentication and related functions.

Unique Advantages

• Compact surface-mount footprint: 8-SOIC package (208-mil) provides a small, industry-standard form factor for board-level integration.
• Flexible serial interface: Standard SPI plus Dual/Quad I/O modes increase effective throughput on supported read instructions without changing the serial bus topology.
• Integrated security primitives: Authentication flash features (root key, HMAC, monotonic counter and status/data read) reduce the need for separate secure elements for many authentication tasks.
• Traceability features: JEDEC ID, SFDP support and a 64-bit unique serial number simplify device identification and system provisioning.
• Wide operating range: 2.7 V–3.6 V supply and −40°C to 85°C operating temperature suit a broad set of commercial and industrial applications.
