Product details
Overview
W25Q01NWTBIQ from Winbond is a 1G-bit (two 512M-bit stacked-die) serial flash memory IC supporting Dual/Quad SPI interfaces, 1.7–1.95V single-supply operation, and up to 133MHz clock frequency. It delivers 66MB/s continuous read throughput, features uniform 4KB sector erase, and enables execute-in-place (XIP) code execution in embedded boot and firmware storage applications.
For engineers reviewing the W25Q01NWTBIQ datasheet, W25Q01NWTBIQ pinout, W25Q01NWTBIQ application, or W25Q01NWTBIQ equivalent, key selection considerations include its TFBGA-24 (8×6 mm, 5×5 ball array) package with dedicated /RESET pin, 4-byte address mode support, JEDEC-compliant ID and SFDP register, and hardware write protection via /WP and /HOLD pins.
Technical Context
The W25Q01NWTBIQ implements a dual-die stacked architecture enabling linear 1G-bit addressing across two independent 512M-bit arrays, each with its own 64-bit unique serial number and status bits (e.g., BUSY, SUS). Its SPI controller supports Mode 0 and Mode 3, with Quad I/O requiring non-volatile QE bit (Status Register-2) configuration.
It integrates three 256-byte security registers with OTP locks, supports Erase/Program Suspend & Resume, and provides configurable output driver strength (DRV1/DRV0) and power-up address mode (ADP) for deterministic boot behavior. Hardware reset (/RESET) is dedicated and functional only in SOIC-16 and TFBGA packages - confirmed for this TBIQ variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 G-bit (2 × 512 M-bit stacked die), organized as 524,288 × 256-byte pages |
| Supply Voltage | 1.7 V to 1.95 V - enables low-power operation in battery-backed and energy-constrained systems |
| Max Clock Frequency | 133 MHz - supports 532 MHz equivalent Quad I/O data rate for high-speed XIP or code shadowing |
| Erase Granularity | 4 KB sectors (32,768 total), 32 KB blocks, 64 KB blocks (2,048 total) - allows fine-grained firmware partitioning |
| Data Retention | 20+ years - validated for long-life industrial and automotive control firmware storage |
| Endurance | 100,000 program-erase cycles per sector - sufficient for field-upgradable bootloader and parameter tables |
| Operating Temp | −40°C to +85°C - qualified for extended-temperature industrial and networking equipment |

Pinout & Package
W25Q01NWTBIQ uses a 24-ball TFBGA package (8×6 mm, 5×5 ball array, package code TB), with ball pitch of 0.8 mm and RoHS-compliant matte tin finish. The /RESET pin is dedicated and functional - distinguishing it from WSON and SOIC variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A4 | /RESET | Dedicated hardware reset input; asserts full device initialization on ≥1 µs low pulse - critical for fail-safe recovery in safety-critical boot paths |
| B2 | CLK | Serial clock input; supports Mode 0/3; timing-critical for all SPI transactions including fast-read and quad-I/O |
| B3 | GND | Ground reference for all I/O and core logic; must be low-impedance to maintain signal integrity at 133 MHz |
| B4 | VCC | 1.7–1.95 V core supply; requires local 1 µF + 100 nF decoupling near ball for stable high-frequency operation |
| C2 | /CS | Chip select input; must transition high→low before instruction acceptance; tracks VCC during power sequencing |
| C4 | /WP (IO2) | Hardware write-protect input (active-low); enables sector-level lock when combined with BP and CMP bits in status register |
| D2 | DO (IO1) | Data output / bidirectional I/O1; used for standard DO, dual-output, or quad-I/O depending on instruction and QE bit state |
| D3 | DI (IO0) | Data input / bidirectional I/O0; carries instructions, addresses, and data; transitions on CLK rising edge in all SPI modes |
| D4 | /HOLD (IO3) | Hold or IO3 input; suspends ongoing SPI transaction when low; repurposed as IO3 in Quad SPI when QE=1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die stacked architecture | Enables seamless 1G-bit linear addressing without external address multiplexing or glue logic |
| JEDEC-compliant SFDP register | Allows automatic host detection of memory geometry, timing, and command set - eliminates hard-coded driver assumptions |
| Three 256-byte security registers | Supports encrypted key storage, secure boot manifests, and tamper-resistant configuration - locked via OTP bits LB1–LB3 |
| 4-byte address mode (B7h/E9h) | Eliminates address wraparound beyond 16 MB; required for full 128 MB capacity access in linear mode |
| Erase/Program Suspend & Resume | Permits background firmware update while servicing real-time interrupts - essential for zero-downtime OTA updates |
| Configurable output drive strength | DRV1/DRV0 bits adjust slew rate and current drive to match PCB trace length and noise margin requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25Q01JVTBIQ | Same 1G-bit density and TFBGA-24 package, but rated for −40°C to +105°C; includes enhanced ESD robustness (±8 kV HBM) | Required for automotive under-hood or high-temp industrial gateways where ambient exceeds +85°C | Select W25Q01JVTBIQ when extended temperature range or higher ESD immunity is mandatory; otherwise W25Q01NWTBIQ suffices for commercial/industrial use. |
| MX25L1G45GM | 1G-bit Macronix part in same TFBGA-24 package; supports 104 MHz max clock (vs. 133 MHz); lacks SFDP register and security registers | Suitable for cost-sensitive designs where XIP performance and secure key storage are not required | Choose MX25L1G45GM only if lower speed and absence of SFDP/security features are acceptable trade-offs for price reduction. |
Compared with W25Q01JVTBIQ, W25Q01NWTBIQ offers identical pinout and feature set but targets standard industrial temperature range; versus MX25L1G45GM, it delivers higher throughput, standardized auto-discovery via SFDP, and certified secure storage - making it preferable for complex, upgradable, or safety-aware systems.

FAQ
What is the package type and pin count of W25Q01NWTBIQ?
W25Q01NWTBIQ uses a 24-ball TFBGA package (8×6 mm, 5×5 ball array, package code TB) with 0.8 mm ball pitch. It includes dedicated /RESET (A4), /CS (C2), CLK (B2), VCC (B4), GND (B3), and four I/O pins (C4, D2, D3, D4) supporting Standard/Dual/Quad SPI operation - confirmed in Winbond's official datasheet revision B.
Does W25Q01NWTBIQ support 4-byte addressing, and how is it enabled?
Yes, W25Q01NWTBIQ supports 4-byte addressing to access its full 128 MB capacity. It is enabled via the Enter 4-Byte Address Mode instruction (B7h), which sets the ADP bit non-volatilely. The device powers up in the mode defined by ADP; switching mid-operation requires explicit B7h/E9h commands - verified in Section 6.1.4 and 7.4.6 of the datasheet.
How does the dual-die architecture of W25Q01NWTBIQ affect memory addressing and reliability?
W25Q01NWTBIQ integrates two independent 512M-bit dies in a single package, presenting a unified 1G-bit linear address space. Each die has its own 64-bit unique ID and separate BUSY/SUS status bits, enabling concurrent status monitoring and fault isolation. This architecture improves yield and reliability without requiring host-side die management - detailed in Section 1 and Figure 2 of the datasheet.
What security features are implemented in W25Q01NWTBIQ beyond basic write protection?
W25Q01NWTBIQ includes three 256-byte security registers with OTP lock bits (LB1–LB3), individual sector/block lock (36h/39h), global lock (7Eh/98h), and SFDP-based parameter discovery. Its hardware /WP pin works with non-volatile BP/CMP bits to enforce sector-level protection - all documented in Sections 2, 7.1.8, and 7.4.44–7.4.48 of the datasheet.
Can W25Q01NWTBIQ be used for execute-in-place (XIP) applications, and what interface mode is recommended?
Yes, W25Q01NWTBIQ is optimized for XIP operation using Quad SPI mode (e.g., Fast Read Quad I/O, EBh), delivering up to 532 MHz equivalent bandwidth. The QE bit (Status Register-2) must be set to enable IO2/IO3, and the 4-byte address mode is required for full 128 MB access. This configuration achieves sub-100 ns instruction fetch latency - specified in Section 2 and Table 8.6 of the datasheet.
