Winbond Electronics Corporation W29N02GWBIBA TR

Overview

W29N02GWBIBA TR from Winbond is a 2G-bit (256MB) SLC NAND Flash memory operating at 1.7–1.95V, organized into 2,048 erasable blocks of 135,168 bytes each (64 pages × 2,112 bytes/page), with x8/x16 bus interface and standard NAND command set including Copy Back and Two-Plane operations. It targets embedded storage in space-constrained, low-power systems such as industrial HMIs and boot code storage.

For engineers reviewing the W29N02GWBIBA TR datasheet, W29N02GWBIBA TR pinout, W29N02GWBIBA TR application, or W29N02GWBIBA TR equivalent, key selection criteria include its 1.8V operation, 25μs random read latency, 250μs typical page program time, 100,000 P/E cycle endurance with 1-bit/528-byte ECC, and support for TSOP1 and VFBGA packages.

Technical Context

This device implements a standard NAND architecture with multiplexed I/O bus, five dedicated control signals (CLE, ALE, #CE, #RE, #WE), and status monitoring via open-drain RY/#BY. It supports both x8 and x16 data widths, enabling flexible system integration without bus width conversion logic.

Two-plane operation allows concurrent read/write/erase across even- and odd-numbered block planes, doubling effective throughput for sequential access patterns. The internal cache register enables pipelined page reads and writes, while the spare area (64 bytes/page) is reserved for ECC metadata and bad-block management.

Key Specifications

Pinout & Package

W29N02GWBIBA TR is packaged in a 63-ball Very Fine Pitch Ball Grid Array (VFBGA) with 0.5mm pitch, footprint size 9mm × 11mm, suitable for high-density PCB layouts. Pin assignments differ between x8 and x16 configurations; this part uses x8 mode per ordering code 'B' and 'I' in the suffix.

FAQ

What is the operating voltage range for W29N02GWBIBA TR?

W29N02GWBIBA TR operates from 1.7V to 1.95V, with nominal 1.8V supply. This narrow range ensures compatibility with modern low-voltage SoC I/O rails and eliminates need for voltage translation. All DC and AC specifications - including 13mA active read current and 10μA standby - are guaranteed across this full range, as verified in Section 10.2 of the datasheet.

Does W29N02GWBIBA TR support both x8 and x16 bus widths?

W29N02GWBIBA TR supports both x8 and x16 configurations, but the 'B' package code and 'I' temperature grade indicate this specific variant is configured for x8 operation. Pin assignment differs between modes (see Figures 3-2 and 3-3), and bus width is determined at power-on via internal configuration registers - no hardware strap pins are used. The x16 mode requires different I/O ball mapping and is not enabled on W29N02GWBIBA TR.

What is the endurance rating of W29N02GWBIBA TR and under what conditions?

W29N02GWBIBA TR guarantees 100,000 program/erase cycles when used with 1-bit-per-528-byte ECC correction, as stated in Feature section footnote (1) and Table 10-7. This rating applies across the full industrial plus temperature range (-40°C to +105°C) and assumes proper wear leveling by the host controller. Without ECC, endurance drops significantly and is not characterized.

How does the Two-Plane operation in W29N02GWBIBA TR improve performance?

Two-Plane operation in W29N02GWBIBA TR allows independent read, program, or erase actions on even- and odd-numbered block planes simultaneously - for example, reading from Plane 0 while programming to Plane 1. This concurrency reduces effective latency for sequential access patterns and increases sustained throughput by up to 2×, as confirmed in Sections 9.1.2 and 9.2.4 of the datasheet.

Is W29N02GWBIBA TR compatible with standard NAND controllers?

Yes, W29N02GWBIBA TR implements the standard NAND command set defined in ONFI 1.0 and JEDEC JESD-68, including mandatory commands (00h, 30h, 80h, 10h, 60h, D0h) and optional features like Copy Back (35h/85h) and Two-Plane (00h-00h-30h). Its timing parameters (e.g., tREA = 25μs, tR = 25ns) meet ONFI timing classes, ensuring interoperability with off-the-shelf NAND controllers.
