Product details
Overview
W25N512GVFIR TR from Winbond is a 512M-bit (64MB) Serial SLC NAND Flash memory with Dual/Quad SPI interface, organized as 32,768 × 2,048-byte pages and 512 × 128KB erasable blocks. It supports 166MHz SPI clock, 50MB/s continuous read transfer rate, on-chip 1-bit ECC, and operates from 2.7V–3.6V across –40°C to +105°C. It enables code shadowing, XIP execution, and data storage in space-constrained embedded systems.
For engineers reviewing the W25N512GVFIR TR datasheet, W25N512GVFIR TR pinout, W25N512GVFIR TR application, or W25N512GVFIR TR equivalent, key selection considerations include BUF-mode default (Buffer Read), TFBGA-24 package compatibility, Quad I/O timing compliance, and ECC-enabled NAND manageability for industrial firmware storage.
Technical Context
The W25N512GVFIR TR implements a serial NAND architecture with dual-mode read operation: Buffer Read (default at power-up) and Continuous Read (BUF=0). Its command set includes standard, dual, and quad SPI instructions - supporting Fast Read Quad I/O (6Bh/6Ch) up to 664MHz equivalent bandwidth and 128KB block erase (D8h) with bad block management via LUT access (A5h).
It integrates volatile and OTP-configurable registers: Protection Register (SR-1) with BP[3:0], WP-E, SRP[1:0]; Configuration Register (SR-2) with ECC-E, BUF, OTP-L, and ODS[1:0]; and Status Register-3 reporting ECC-1/0, P-FAIL/E-FAIL, and BUSY. Write protection combines hardware (/WP, /HOLD) and software (SR bits) layers with power-supply lock-down capability.

| Interface Speed | Up to 166 MHz SPI clock; 332 MHz (Dual I/O) or 664 MHz (Quad I/O) effective throughput |
| Data Transfer Rate | 50 MB/s continuous read in Continuous Read Mode - eliminates per-page "Page Data Read" overhead |
| Voltage & Temp | 2.7 V to 3.6 V supply; –40°C to +105°C industrial temperature range (confirmed for F/R/T suffix variants) |
| ECC & Reliability | On-chip 1-bit ECC per 528-byte sector; 100,000 program/erase cycles; 10-year data retention with ECC active |
| Power Consumption | 25 mA active, 10 µA standby, 1 µA deep power-down - enables low-energy boot and firmware update scenarios |
| OTP & Identity | Ten 2KB OTP pages, one 2KB Unique ID page, one 2KB parameter page - supports secure device binding and calibration storage |
Pinout & Package
W25N512GVFIR TR uses the 24-ball TFBGA 8×6-mm package (package code B, 5×5 ball array), with 8 functional terminals and multiple NC balls. Pin assignments follow JEDEC-standard ball layout optimized for high-density PCB routing and thermal dissipation in industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | CLK | Input: Serial clock for all SPI modes; timing-critical path requiring controlled impedance and minimal skew |
| B3 | GND | Ground reference for all I/O and core logic; must be low-inductance connection to minimize noise coupling |
| B4 | VCC | Primary 2.7–3.6V power supply; requires local 1µF + 0.1µF decoupling near ball for stable read/write operation |
| C2 | /CS | Active-low chip select; must transition high→low before instruction acceptance; tracks VCC during power sequencing |
| C4 | /WP (IO2) | I/O: Hardware write protect input (active-low) when WP-E=1; otherwise IO2 for Quad SPI data |
| D2 | DO (IO1) | I/O: Data output in Standard/Dual SPI; bidirectional IO1 in Dual/Quad mode - shared with status/data reads |
| D3 | DI (IO0) | I/O: Data input in Standard SPI; bidirectional IO0 in Dual/Quad mode - primary instruction/address entry point |
| D4 | /HOLD (IO3) | I/O: Active-low hold input suspends ongoing SPI transfer; otherwise IO3 for Quad SPI - no /HOLD function in Quad mode |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode (BUF=0) | Enables single-command sequential access across full memory array - eliminates inter-page command latency for firmware loading |
| Configurable ECC Enable (ECC-E) | On-chip 1-bit error correction per 528-byte sector - reduces host-side ECC processing burden and improves system-level reliability |
| Bad Block Management (BBM) | Hardware-accelerated invalid block tracking via dedicated A1h/A5h commands and internal LUT - simplifies NAND driver development |
| OTP Page Support (10 × 2KB) | One-time programmable memory for calibration data, security keys, or production configuration - immune to field rewrites |
| Flexible Write Protection | Combines /WP pin control, SR-1 BP bits (block-level), SRP bits (register lock), and power-supply lock-down - multi-layer security for firmware partitions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NAND flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25N512GVFIM TR | Same die, identical specs, but in 8-pad WSON 8×6-mm (package code E) instead of TFBGA-24 | Requires PCB redesign for smaller footprint and different thermal profile; no /HOLD or /WP pins exposed | Select for cost-sensitive consumer designs where TFBGA assembly complexity is prohibitive |
| MT29F512G08CFAAAWP-IT:F | 512Gb SLC NAND with ONFI 3.2 interface; parallel x8 bus, not SPI; higher density but incompatible protocol | Requires NAND controller with ONFI timing engine and ECC offload - not drop-in for SPI-based hosts | Choose only when migrating to controller-based NAND architecture with dedicated ECC hardware |
Compared with W25N512GVFIR TR, the W25N512GVFIM TR offers identical functionality in a simpler WSON package but sacrifices /WP and /HOLD pins and thermal performance; the MT29F512G08CFAAAWP-IT:F provides greater density and speed but mandates full NAND controller integration - neither is pin- or command-compatible.

FAQ
What is the default read mode for W25N512GVFIR TR at power-up?
The W25N512GVFIR TR powers up in Buffer Read Mode (BUF=1) by default, as indicated by its "R" suffix in the part numbering scheme. This mode requires explicit "Page Data Read" (13h) commands before each page access. To enable Continuous Read Mode, the BUF bit in Configuration Register (SR-2) must be cleared to 0 via Write Status Register (1Fh) instruction.
Does W25N512GVFIR TR support Quad SPI commands like Fast Read Quad I/O?
Yes, W25N512GVFIR TR fully supports Quad SPI operation including Fast Read Quad I/O (EBh) and Fast Read Quad I/O with 4-Byte Address (ECh), achieving up to 664MHz equivalent bandwidth. All IO0–IO3 pins (DI, DO, /WP, /HOLD) function as bidirectional data lines in Quad mode, though /WP and /HOLD lose their dedicated control functions during Quad transfers.
How is bad block management implemented in W25N512GVFIR TR?
W25N512GVFIR TR implements hardware-assisted bad block management using an internal Look-Up Table (LUT). The A1h instruction marks blocks as invalid, and A5h reads the full LUT contents. The LUT-F status bit (SR-3) indicates table full condition. This eliminates need for host-side bad block tables and simplifies driver development for embedded Linux or bare-metal systems.
What is the role of the /WP and /HOLD pins on W25N512GVFIR TR?
On W25N512GVFIR TR, /WP (IO2) and /HOLD (IO3) serve dual roles: in Standard/Dual SPI mode, they act as active-low hardware controls for write protection and transfer suspension; in Quad SPI mode, they become general-purpose I/O lines (IO2/IO3). Their functionality is gated by the WP-E bit (SR-1) and H-DIS bit (SR-2), respectively.
Can W25N512GVFIR TR be used for Execute-in-Place (XIP) applications?
Yes, W25N512GVFIR TR supports XIP via Dual/Quad SPI interfaces, leveraging its 166MHz clock and Fast Read Dual/Quad I/O instructions (BBh/ECh) to deliver sufficient bandwidth for direct code execution. Continuous Read Mode further enhances XIP performance by enabling seamless sequential access across page boundaries without command reissuance.
