Winbond Electronics Corporation W29N08GWBIBF TR

Overview

W29N08GWBIBF 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 × 64 pages × 2,112 bytes/page (2,048B main + 64B spare), supporting x8/x16 bus width, two-plane operations, and ONFI-compatible command set for embedded storage. It delivers 25μs random read, 250μs typical page program, and 2ms typical block erase - optimized for code shadowing, firmware storage, and media buffering in space-constrained industrial systems.

For engineers reviewing the W29N08GWBIBF datasheet, W29N08GWBIBF pinout, W29N08GWBIBF application, or W29N08GWBIBF equivalent, key selection criteria include its 1.7–1.95V supply range, 100,000-program/erase cycle endurance with 4-bit/528-byte ECC, industrial temperature rating (−40°C to +85°C), and dual-plane concurrent operation support for improved throughput in boot and logging applications.

Technical Context

The W29N08GWBIBF implements a standard NAND interface with multiplexed I/O bus and five dedicated control signals (CLE, ALE, #CE, #RE, #WE) to manage command, address, and data latching via edge-triggered protocols. Its internal architecture includes a cache register, data register, high-voltage generator, and dual-plane NAND array enabling simultaneous read/write/erase across planes.

It supports ONFI 2.3–compatible commands including COPY BACK, READ PARAMETER PAGE (ECh), SET/GET FEATURES (EFh/EEh), and READ UNIQUE ID (EDh), with programmable features at addresses 80h and 81h. Block lock and OTP functions are available but require direct coordination with Winbond per datasheet note.

FAQ

What is the operating voltage range for the W29N08GWBIBF?

The W29N08GWBIBF operates from 1.7 V to 1.95 V, with nominal 1.8 V supply. This narrow range simplifies power design in battery-powered or energy-harvested systems and eliminates need for level shifters when interfacing with 1.8V logic. All DC and AC specifications in the datasheet are characterized across this full range, including 20 μA standby current at 1.8V.

Does the W29N08GWBIBF support both x8 and x16 bus widths?

Yes, the W29N08GWBIBF supports configurable x8 or x16 data bus width depending on system controller configuration and package variant. The 63-ball VFBGA (B-code) version used in W29N08GWBIBF implements both modes via internal configuration bits - x16 mode doubles data throughput per cycle but requires full 16-bit I/O routing on PCB.

What is the significance of the "B" in the part number W29N08GWBIBF?

The "B" in W29N08GWBIBF denotes the 63-ball VFBGA package (package code B) per Winbond's ordering nomenclature. It distinguishes this variant from the 48-pin TSOP1 version (code S) and confirms mechanical compatibility with fine-pitch BGA footprints measuring 9 mm × 11 mm - critical for layout reuse in space-constrained industrial modules.

How does the W29N08GWBIBF handle bad block management?

The W29N08GWBIBF implements factory-marked invalid blocks and supports dynamic bad block detection via READ STATUS (70h) and READ PARAMETER PAGE (ECh). Host firmware must scan initial blocks at power-on and maintain a bad block table; the device provides dedicated commands (e.g., COPY BACK) to relocate data from failing blocks without external RAM buffering.

Is the W29N08GWBIBF compatible with ONFI 2.3 standards?

Yes, the W29N08GWBIBF is fully ONFI 2.3–compliant, supporting mandatory commands (READ ID, READ STATUS, RESET), optional features (COPY BACK, TWO PLANE), and parameter page (ECh) with standardized timing and feature descriptors. This ensures plug-and-play integration with ONFI-aware controllers and simplifies driver development across platforms.
