Product details
Overview
W29N01HVSINA from Winbond is a 1G-bit (128MB) SLC NAND Flash memory operating at 2.7V–3.6V, organized into 1,024 blocks of 64 pages each (2,112 bytes/page), supporting standard NAND command set including Copy Back, with industrial temperature range (−40°C to +85°C) and 100,000 program/erase cycles - used in embedded storage for code shadowing, firmware updates, and media data logging in space-constrained industrial controllers.
For engineers reviewing the W29N01HVSINA datasheet, W29N01HVSINA pinout, W29N01HVSINA application, or W29N01HVSINA equivalent, this page delivers verified package mapping (48-pin TSOP1), confirmed timing values (25ns sequential read, 250μs page program), real-world endurance (100K cycles with 1-bit/528-byte ECC), and validated alternative options for industrial-grade NAND replacement scenarios.
Technical Context
The W29N01HVSINA implements a multiplexed x8 interface using five dedicated control signals (CLE, ALE, #CE, #WE, #RE) to manage command, address, and data transfers over shared I/O[0–7] pins. Its internal architecture includes a 2,112-byte data register, column/row decoders, high-voltage generator, and status register with open-drain RY/#BY output for operation monitoring.
It supports ONFI-compliant identification (via READ ID at address 20h), parameter page access (ECh), and deterministic timing modes: random read (25μs), sequential read (25ns), page program (250μs typ.), and block erase (2ms typ.). Write protection is hardware-enforced via active-low #WP, and standby current is 10μA typ. at 3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 G-bit / 128 MB total capacity - sufficient for boot code, firmware images, and log buffers in resource-limited microcontrollers. |
| Page size | 2,112 bytes (2,048 main + 64 spare) - enables ECC metadata storage per page without external overhead. |
| Block size | 135,168 bytes (64 × 2,112) - defines minimum erasable unit; impacts wear leveling granularity and update latency. |
| Read speed | 25 ns sequential cycle time - supports high-throughput streaming of firmware or media data from contiguous pages. |
| Program time | 250 μs typical page program - determines write latency for small firmware patches or configuration updates. |
| Endurance | 100,000 P/E cycles (with 1-bit/528-byte ECC) - sets usable lifetime for frequent field-upgrade applications. |
| Data retention | 10 years at 85°C - ensures long-term reliability in unpowered industrial deployments. |
| Operating voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V supply rails and tolerant of brown-out conditions. |
Pinout & Package
W29N01HVSINA is packaged in a 48-pin TSOP1 (Package Code S), 12 mm × 20 mm footprint, with all power (Vcc/Vss) and signal pins arranged for standard PCB layout compatibility and thermal management in dense embedded modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low enable: places device in standby (10 μA) when high; required low state for all operations. |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and data - synchronizes all input transfers. |
| #RE | Read Enable | Falling-edge triggered serial data output; column address auto-increments per pulse for sequential reads. |
| ALE | Address Latch Enable | Signals I/O bus content as row/column address during rising edge of #WE. |
| CLE | Command Latch Enable | Signals I/O bus content as command byte (e.g., 00h, 80h, 60h) during rising edge of #WE. |
| #WP | Write Protect | Hardware lock: disables all program/erase when pulled low - prevents accidental corruption during power transitions. |
| RY/#BY | Ready/Busy | Open-drain status indicator: low during active operations (read/program/erase); requires external pull-up. |
| I/O[0–7] | Bidirectional Data Bus | Multiplexed path for commands (1 byte), addresses (4 bytes), and data (2,112 bytes/page). |
| Vcc | Power Supply | 2.7–3.6 V primary supply; all Vcc pins must be connected - no floating power terminals permitted. |
| Vss | Ground | Reference ground; all Vss pins must be connected - critical for noise immunity and timing stability. |
Key Features
| Feature | Design Value |
|---|---|
| SLC NAND architecture | Guarantees consistent 100,000 P/E cycles and 10-year data retention - essential for mission-critical firmware storage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F1G08ABAEAH4-IT:E | 1Gb x8 SLC NAND, 3.3V, 48-ball VFBGA, 25ns read, but requires 1.8V I/O interface and different command timing margins. | Targeted for mobile/embedded SoCs with dual-voltage I/O; not drop-in compatible due to VI/O mismatch and timing skew. | Select only if host controller supports 1.8V I/O signaling and timing revalidation is feasible. |
| TC58CVG1S3HRAIJ | 1Gb x8 SLC NAND, 3.3V, 48-pin TSOP1, identical pinout and voltage, but rated for −25°C to +85°C (not industrial grade). | Limited to commercial/extended temp applications; lacks guaranteed −40°C startup and retention compliance. | Acceptable for cost-sensitive non-industrial designs where full industrial qualification is not mandated. |
Compared with W29N01HVSINA, MT29F1G08ABAEAH4-IT:E demands I/O voltage redesign and timing validation, while TC58CVG1S3HRAIJ omits −40°C qualification - making W29N01HVSINA the sole option meeting full industrial spec with TSOP1 drop-in compatibility.

FAQ
What is the exact memory organization of the W29N01HVSINA?
The W29N01HVSINA contains 1,024 erasable blocks, each consisting of 64 programmable pages of 2,112 bytes (2,048 main + 64 spare). Total capacity is 138,412,032 bytes (128 MB), with block size = 135,168 bytes and page size fixed at 2,112 bytes. This structure is confirmed in Section 6.1 and Table 6.1 of the official datasheet.
Does W29N01HVSINA support ONFI standards?
Yes, W29N01HVSINA supports ONFI identification via the READ ID command (90h) with address 20h, returning four-byte ONFI signature (4Fh, 4Eh, 46h, 49h) as specified in Table 9.2. However, it does not implement full ONFI 1.0+ timing or feature sets - only basic identification and parameter page (ECh) compliance.
What is the purpose of the 64-byte spare area in each page of W29N01HVSINA?
The 64-byte spare area in each 2,112-byte page of W29N01HVSINA is reserved for error management functions - primarily storing ECC parity bits, logical-to-physical block mapping metadata, and wear-leveling counters. It is inaccessible during normal read/write operations unless explicitly accessed via RANDOM DATA OUTPUT within the same page.
Can W29N01HVSINA be used with a 1.8V I/O interface?
No, W29N01HVSINA is strictly a 3.3V device with VI/O tied to Vcc (2.7–3.6V). Its I/O[0–7], CLE, ALE, #CE, #WE, #RE, #WP, and RY/#BY pins operate at 3.3V logic levels. Interfacing with 1.8V controllers requires level-shifting circuitry - the device itself does not support dual-voltage I/O.
How does hardware write protection (#WP) function on W29N01HVSINA?
When the #WP pin of W29N01HVSINA is driven low, all program and erase operations are immediately disabled - regardless of command sequence or timing. This hardware lock persists until #WP returns high, providing fail-safe protection against corruption during power transitions, resets, or software faults.
