Product details
Overview
W29N08GZBIBA from Winbond is an 8G-bit (1GB) single-supply 1.8V SLC NAND Flash memory in 63-ball VFBGA package, organized as 8,192 erasable blocks of 135,168 bytes each, with 64 pages per block and 2,112-byte pages (2048+64 byte spare). It supports x8/x16 bus width, two-plane operations, Copy Back, and ONFI-compatible command set for embedded storage in space-constrained systems.
For engineers reviewing the W29N08GZBIBA datasheet, W29N08GZBIBA pinout, W29N08GZBIBA application, or W29N08GZBIBA equivalent, key selection criteria include 1.8V operation, 25μs random read latency, 250μs typical page program time, 2ms block erase time, 100,000 P/E cycles with 1-bit/528-byte ECC, and industrial temperature support (–40°C to +85°C).
Technical Context
This device implements a standard NAND interface with multiplexed I/O bus and five dedicated control signals (CLE, ALE, #CE, #RE, #WE) for command/address/data latching. Its internal architecture includes dual-plane memory array, cache register, data register, and high-voltage generator enabling concurrent operations across planes.
It executes ONFI-standard commands including PAGE READ (00h-30h), TWO PLANE READ (00h-00h-30h), RANDOM DATA OUTPUT (05h-E0h), PAGE PROGRAM (80h-10h), TWO PLANE PROGRAM, BLOCK ERASE (60h-D0h), and enhanced status reporting (78h), all compliant with 1.8V timing specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 8G-bit (1,073,741,824 bytes) total capacity, realized via chip-stacked die configuration |
| Supply Voltage | 1.7V–1.95V operation; enables low-power design in battery-backed or energy-sensitive embedded systems |
| Page Size | 2,112 bytes (2048 main + 64 spare); spare area reserved for ECC metadata and bad-block management |
| Block Size | 135,168 bytes (64 × 2,112-byte pages); defines minimum erasable unit for wear leveling and firmware updates |
| Random Read Time | 25μs max; determines latency for small-data access in boot code or configuration retrieval |
| Page Program Time | 250μs typical; impacts firmware update speed and logging throughput in real-time applications |
| Endurance | 100,000 program/erase cycles with 1-bit/528-byte ECC; specifies usable lifetime under sustained write workloads |
| Data Retention | 10 years at 25°C; guarantees nonvolatile storage integrity without refresh in offline or archival use cases |
Pinout & Package
W29N08GZBIBA uses a 63-ball Very Fine-Pitch Ball Grid Array (VFBGA) package (package code B), footprint compatible with JEDEC MO-276AA, dimensions 9.0 mm × 11.0 mm × 1.0 mm (max), suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable; places device in standby (20μA) when high, required for multi-chip select arbitration |
| #RE | Read Enable | Controls serial output timing; valid data appears after tREA (25ns) from falling edge, increments column address |
| #WE | Write Enable | Latches commands, addresses, and data on rising edge; synchronizes all input transfers to NAND protocol |
| ALE | Address Latch Enable | Signals that I/O bus carries row/column address; enables address register capture during #WE rise |
| CLE | Command Latch Enable | Signals that I/O bus carries command byte (e.g., 00h, 80h, 60h); enables command register capture during #WE rise |
| RY/#BY | Ready/Busy Output | Open-drain status indicator; low = active operation (read/program/erase), high = ready for next command |
| #WP | Write Protect | Hardware lock; low disables all program/erase commands, preventing accidental corruption during power transitions |
| I/O[0–7] | Bidirectional Data Bus | Multiplexed path for commands (8-bit), addresses (5-cycle), and data (2112-byte pages); supports x8 mode only in this variant |
| Vcc / Vss | Power / Ground | Four Vcc and four Vss balls ensure stable 1.8V supply delivery and noise immunity in high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Two-plane operation | Enables concurrent read/program between even- and odd-numbered block planes, doubling effective bandwidth for sequential access |
| Copy Back command | Permits page-to-page relocation within same die without external buffering, reducing host RAM overhead in garbage collection |
| ONFI-compliant interface | Ensures interoperability with standard NAND controllers and avoids proprietary driver development in Linux/Yocto BSPs |
| 1.8V-only operation | Eliminates need for dual-voltage regulators; simplifies power design and reduces BOM cost in portable and IoT edge devices |
| Industrial temperature range | Rated –40°C to +85°C; validated for deployment in automotive infotainment, industrial HMIs, and outdoor telemetry units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F8G08ABABH4-IT | 8G-bit, 3.3V operation; different voltage domain, no 1.8V compatibility; uses 48-pin TSOP1 package | Requires level-shifting circuitry and separate 3.3V rail; unsuitable for 1.8V-only designs or space-constrained layouts | Select only if existing board already supports 3.3V NAND and TSOP1 footprint; not drop-in for W29N08GZBIBA |
| TC58NVG2S3HTAI0 | 8G-bit, 1.8V, x8 interface; Toshiba (Kioxia) part with identical VFBGA-63 package and ONFI 2.3 compliance | Same pinout and command set; differs in timing parameters (e.g., 30μs random read vs. 25μs) and ECC requirements (4-bit BCH) | Valid alternative where layout reuse is critical; verify timing margins and ECC engine compatibility before substitution |
Compared with MT29F8G08ABABH4-IT, W29N08GZBIBA eliminates voltage translation complexity; compared with TC58NVG2S3HTAI0, it offers faster random read and simpler ECC (1-bit/528-byte), easing integration in resource-limited microcontrollers.

FAQ
What is the operating voltage range for W29N08GZBIBA?
W29N08GZBIBA operates strictly within 1.7V to 1.95V. It is not 3.3V-tolerant and requires a dedicated 1.8V power rail. Operation outside this range may cause data corruption or permanent damage. The device draws 13mA typical during active read/write and only 20μA in CMOS standby mode, making it suitable for low-power embedded systems.
Does W29N08GZBIBA support x16 bus width?
No, W29N08GZBIBA (package code B, suffix 'BI') is configured for x8 operation only. Although the datasheet references x16 pin assignments for the same VFBGA package, this specific part number is specified and tested exclusively for 8-bit data interface. Attempting x16 mode will result in undefined behavior and is not supported.
What is the meaning of 'Z' in W29N08GZBIBA?
The 'Z' in W29N08GZBIBA denotes the device's feature set and revision level per Winbond's ordering nomenclature - specifically indicating support for ONFI 2.3 commands, two-plane operation, Copy Back, and industrial temperature grade (–40°C to +85°C). It distinguishes this variant from earlier 'W' or 'X' versions with differing command subsets or qualification levels.
How many valid blocks does W29N08GZBIBA guarantee?
W29N08GZBIBA guarantees a minimum of 7,936 valid blocks (out of 8,192 total) at shipment, with up to 256 initial invalid blocks pre-mapped per datasheet Table 12-1. Bad block management is handled transparently via the spare area and standard ONFI parameter page; no host-side remapping logic is required for basic operation.
Is W29N08GZBIBA pin-compatible with other Winbond NAND parts in VFBGA-63?
W29N08GZBIBA shares the same 63-ball VFBGA mechanical footprint and pinout as other Winbond W29N08GW/Z variants in package code B, including identical signal placement for #CE, #RE, #WE, CLE, ALE, RY/#BY, #WP, I/O[0–7], Vcc, and Vss. However, functional compatibility depends on command set support and timing - always validate against the target controller's NAND driver stack.
