Product details
Overview
W29N01GZDIBA from Winbond is a 1G-bit (128MB) single-level cell (SLC) NAND Flash memory operating at 1.7–1.95V, organized into 1,024 erasable blocks of 135,168 bytes each (64 × 2,112-byte pages), with 2,048-byte main data + 64-byte spare area per page. It supports X8/X16 bus width, sequential and random cache read, copy-back, OTP programming, and ONFI-compatible command set for embedded code shadowing, solid-state storage, and media data retention in space-constrained industrial systems.
For engineers reviewing the W29N01GZDIBA datasheet, W29N01GZDIBA pinout, W29N01GZDIBA application, or W29N01GZDIBA equivalent, key selection considerations include its 48-ball VFBGA package, 100,000 program/erase cycles with 1-bit/528-byte ECC, 25μs random read latency, 300μs typical page program time, and industrial temperature range (−40°C to +85°C).
Technical Context
The W29N01GZDIBA implements a standard NAND interface with multiplexed 8-/16-bit I/O bus and five dedicated control signals (CLE, ALE, #CE, #WE, #RE) for command, address, and data latching. Its internal architecture includes a cache register, data register, high-voltage generator, and status register, enabling pipelined read/write operations and hardware-managed bad-block handling.
It supports ONFI-compliant features including GET/SET FEATURES (EFh/EEh), OTP area access (A0h/AFh/A5h), and block lock via vendor-specific commands. The device uses open-drain RY/#BY for operation status indication and DNU/N.C. pins strictly defined per VFBGA48 layout - no floating Vcc/Vss connections permitted.
Key Specifications

Pinout & Package
W29N01GZDIBA is housed in a 48-ball Very Fine-Pitch Ball Grid Array (VFBGA) package measuring 8 mm × 6.5 mm with 0.8 mm ball pitch and 0.45 mm ball diameter (Package Code D). All Vcc and Vss balls must be connected; DNU and N.C. balls are strictly unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable: places device in standby (10 μA) when high; required low for all operations |
| #WE | Write Enable | Rising-edge latch control for commands, addresses, and input data - synchronizes all write-phase transfers |
| #RE | Read Enable | Rising-edge initiates serial output from data register; falling-edge timing (tREA) defines data valid window |
| CLE | Command Latch Enable | High enables command latching on next #WE rising edge - isolates command phase from address/data phases |
| ALE | Address Latch Enable | High enables address latching on next #WE rising edge - separates column/row addressing cycles |
| #WP | Write Protect | Active-low hardware lock: disables all program/erase when asserted - prevents accidental corruption |
| RY/#BY | Ready/Busy | Open-drain status indicator: low = active operation (read/program/erase); requires external pull-up |
| I/O[0–7] | Bidirectional Data Bus | Multiplexed path for commands (8-bit), addresses (4-cycle), and data (X8 mode); IO8–IO15 are N.C. in X8 |
| Vcc | Power Supply | 1.7–1.95 V core supply - all four Vcc balls must be connected for stable operation |
| Vss | Ground | Reference ground - all three Vss balls must be connected; floating grounds cause timing violations |
Key Features
| Feature | Design Value |
|---|---|
| ONFI-Compatible Command Set | Supports standardized NAND commands (00h/30h, 80h/10h, 60h/D0h) plus extended features (EFh/EEh, A0h/AFh) for interoperability with mainstream controllers |
| Cache Read & Program | Reduces average read latency to ≤35 ns (sequential) and accelerates multi-page writes by buffering data internally before committing to array |
| Copy-Back Operation | Enables page-to-page relocation within same die without host data transfer - critical for wear leveling and garbage collection efficiency |
| OTP Area Support | One-time programmable region accessible via A0h/AFh/A5h commands - used for secure keys, calibration data, or factory configuration locking |
| Hardware Write Protection | Dedicated #WP pin provides physical, non-volatile lock against unintended program/erase - independent of software state or power loss |
| Industrial Temperature Range | Guaranteed operation from −40°C to +85°C - qualified for automotive infotainment, industrial HMIs, and outdoor IoT gateways |

FAQ
What is the operating voltage range for W29N01GZDIBA?
The W29N01GZDIBA operates over a strict 1.7 V to 1.95 V supply range. This narrow 1.8 V nominal window ensures optimal SLC cell performance, low leakage, and compatibility with modern low-power SoCs. Operation outside this range may cause command timeout, data corruption, or premature endurance failure. All four Vcc balls must be properly decoupled per Winbond's layout guidelines.
Does W29N01GZDIBA support both X8 and X16 bus configurations?
Yes, W29N01GZDIBA supports both X8 and X16 data bus widths. In X8 mode, only I/O[0–7] are active; I/O[8–15] are No Connect. In X16 mode, all 16 I/O lines function, halving address cycle count for row/column access. Bus width is determined by hardware strap or initialization sequence - no internal register setting required. Pin assignment remains identical in both modes.
How does the Ready/Busy (RY/#BY) signal behave during W29N01GZDIBA operations?
RY/#BY is an open-drain output that goes low during any active operation - including page read, program, block erase, cache read, copy-back, and OTP access - and returns high upon completion. Its assertion timing aligns with tR (read), tPROG (program), and tBERS (erase) specifications. External pull-up is mandatory; Winbond specifies ≥10 kΩ for reliable noise immunity in industrial EMI environments.
What is the purpose of the spare area in each 2,112-byte page of W29N01GZDIBA?
The 64-byte spare area in each W29N01GZDIBA page is reserved for error correction codes (ECC), logical-to-physical block mapping, wear-leveling counters, and bad-block flags. With 1-bit/528-byte ECC mandated for the 100,000-cycle endurance rating, this area enables robust correction of bit errors accumulated over time. Host firmware or controller must manage spare-area content per ONFI specification.
Can W29N01GZDIBA be used in automotive applications?
W29N01GZDIBA is rated for industrial temperature (−40°C to +85°C) and qualified per JEDEC standards, but it is not AEC-Q100 qualified. It is suitable for under-hood-adjacent or cabin-mounted automotive subsystems (e.g., infotainment head units, ADAS display buffers) where ambient temperature stays within spec and vibration/shock profiles meet industrial-grade expectations. For engine-control or safety-critical domains, AEC-Q100-certified alternatives are required.
