Winbond Electronics Corporation W29N01HVBINF

Overview

W29N01HVBINF 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), with x8 multiplexed I/O interface and standard NAND command set. It delivers 25ns sequential read cycle time, 250μs typical page program time, and supports Copy Back, Read ID, and Parameter Page commands for embedded storage in space-constrained systems.

For engineers reviewing the W29N01HVBINF datasheet, W29N01HVBINF pinout, W29N01HVBINF application, or W29N01HVBINF equivalent, this device serves as a drop-in replacement for industrial-grade NAND in boot code storage, firmware update partitions, and media buffering-where 100,000 P/E cycles, 10-year data retention, and TSOP1/VFBGA packaging are required.

Technical Context

The W29N01HVBINF implements a standard NAND architecture with separate Command Latch Enable (CLE) and Address Latch Enable (ALE) signals, enabling time-multiplexed command/address/data transfer over an 8-bit I/O bus. Its control logic interprets ONFI-compatible commands including PAGE READ (00h/30h), BLOCK ERASE (60h/D0h), and READ PARAMETER PAGE (ECh).

It features dedicated status signaling via open-drain RY/#BY and hardware write protection via #WP, with all Vcc/Vss pins requiring connection per design. The device uses Single-Level Cell technology and supports random data access within a loaded page using 05h/E0h sequences after initial page load.

Key Specifications

Pinout & Package

W29N01HVBINF is packaged in a 63-ball Fine-Pitch Ball Grid Array (VFBGA, Package Code B), 9 mm × 11 mm footprint, suitable for high-density PCB layouts. All Vcc and Vss balls must be connected; DNU and N.C. balls are unconnected and must remain floating.

FAQ

What is the operating temperature range for W29N01HVBINF?

W29N01HVBINF is rated for industrial temperature operation from –40°C to +85°C. This range is validated per its datasheet specifications and supports deployment in harsh environments such as factory automation controllers, outdoor smart meters, and medical equipment without thermal derating. The device maintains full functionality-including 100,000 P/E cycles and 10-year data retention-across this entire range.

Does W29N01HVBINF support ONFI standards?

Yes, W29N01HVBINF supports ONFI 1.0 identification via the READ ID command (90h followed by address 20h), returning 'ONFI' ASCII signature bytes. It also implements the ONFI Parameter Page (ECh command) with standardized fields for geometry, timing, and feature flags-enabling interoperability with ONFI-aware controllers and simplifying initialization in multi-vendor designs.

How many I/O pins does W29N01HVBINF use for data, address, and command transfer?

W29N01HVBINF uses eight bidirectional I/O pins (I/O[0–7]) for time-multiplexed transfer of commands (1 byte), addresses (four 8-bit cycles), and data (2,112 bytes per page). This x8 interface eliminates the need for parallel address buses and reduces pin count versus parallel NOR, making it ideal for compact MCU-based systems with limited GPIO resources.

What is the purpose of the RY/#BY pin on W29N01HVBINF?

The RY/#BY pin on W29N01HVBINF is an open-drain output that signals device busy status: it pulls low during active operations (page read, program, block erase) and returns high upon completion. This allows the host controller to poll or interrupt on state change-ensuring precise timing control without fixed delays-and is essential for deterministic firmware update sequences in safety-critical applications.

Can W29N01HVBINF be used without external ECC hardware?

W29N01HVBINF does not include on-die ECC; it relies on external controller-based ECC (e.g., 1-bit/528-byte Hamming or BCH). Its endurance and retention specs assume proper ECC implementation. While functional without ECC for non-critical data, Winbond specifies 100,000 P/E cycles and 10-year retention only when used with compliant ECC-so external ECC is mandatory for production deployments meeting datasheet guarantees.
