W74M12FVZPIQ

The W74M12FVZPIQ is a 128‑Mbit serial flash memory device from Winbond's SpiFlash® family. It implements NAND-based non-volatile flash organized as 16M x 8 and supports SPI with Dual/Quad I/O and on‑device secure authentication functions.

Designed for space-constrained embedded systems, the device operates from a single 2.7 V to 3.6 V supply, supports execute-in-place (XIP) via Dual/Quad SPI, and is offered in a compact 8-pin package with an exposed pad for thermal performance.

Key Features

• Memory Capacity & Organization — 128 Mbit total capacity, organized as 16M x 8 for byte-oriented access.
• Memory Technology — NAND flash non-volatile memory format suitable for code and data storage.
• Serial Interface — SPI with Dual and Quad I/O support to increase throughput for read operations.
• High-Speed SPI — Datasheet documents support for SPI clock frequencies up to 104 MHz for standard, Dual and Quad fast read operations.
• Secure Authentication — On-device authentication features including HMAC key handling, monotonic counter, and dedicated authentication commands and status registers.
• Device Identification & Security — JEDEC-standard manufacturer/device ID support, a 64-bit unique serial number, and three 256-byte security registers.
• Voltage & Temperature — Single-supply operation from 2.7 V to 3.6 V; industrial temperature range of −40 °C to 85 °C (TA).
• Package — Available in an 8-pin exposed-pad package (8-WDFN / 8-WSON, 6 × 5 mm) for compact PCB integration and improved thermal dissipation.

Typical Applications

• Embedded Firmware Storage — Stores boot code and firmware images for microcontroller-based systems where small footprint non-volatile memory is required.
• Execute-in-Place (XIP) — Dual/Quad SPI supports executing code directly from flash (XIP) to reduce RAM requirements for code shadowing.
• Data and Media Storage — Retains voice, text or general data in space-constrained devices requiring non-volatile storage.
• Secure Key/Identity Storage — On-chip authentication features and unique serial number make it suitable for device identity, secure boot or authenticated storage functions.

Unique Advantages

• Quad I/O Throughput — Dual/Quad SPI modes increase effective data rates for read access, enabling faster code fetch and data transfer when used with supporting controllers.
• Built‑in Authentication — HMAC-related commands, monotonic counter and security registers provide hardware-level primitives for secure authentication and protected operations.
• Compact, Thermally Aware Package — 8-pin exposed-pad package (8-WDFN / 8-WSON, 6 × 5 mm) reduces PCB area while supporting thermal management in compact designs.
• JEDEC Compatibility — Supports JEDEC-standard manufacturer/device ID and SFDP for interoperability with standard SPI flash tooling and firmware.
• Wide Supply and Temperature Range — 2.7 V–3.6 V supply and −40 °C to 85 °C operating range suit a broad set of industrial and commercial embedded applications.
