Winbond Electronics Corporation W29N08GVSIAA TR

Overview

W29N08GVSIAA from Winbond is an 8G-bit (1GB) single-supply 3.3V SLC NAND Flash memory in 48-pin TSOP1 package, organized as 8,192 blocks × 64 pages × 2,112 bytes/page (2,048B main + 64B spare), supporting standard ONFI-compatible command set including two-plane read/program, cache operations, and copy-back. It targets embedded storage in space-constrained industrial systems requiring reliable code shadowing and media data retention.

For engineers reviewing the W29N08GVSIAA datasheet, W29N08GVSIAA pinout, W29N08GVSIAA application, or W29N08GVSIAA equivalent, key selection criteria include its 25μs random read latency, 250μs typical page program time, 100,000 P/E cycle endurance with 1-bit/528-byte ECC, industrial temperature range (–40°C to +85°C), and x8 multiplexed I/O interface compatibility with legacy NAND controllers.

Technical Context

This device implements a single-die SLC NAND architecture with dedicated logic control, high-voltage generator, and dual-cache register design enabling concurrent two-plane operations. Its command protocol relies on CLE/ALE latching via rising edge of #WE, with RY/#BY open-drain status signaling and #WP-driven hardware write protection.

Memory organization follows strict ONFI-aligned addressing: column addresses A0–A11 in first two cycles, row addresses A12–A30 across next three cycles, and full 2,112-byte page access with 64-byte spare area reserved for ECC metadata. Block erase (60h-D0h) and page program (80h-10h) are atomic, non-interruptible operations governed by status register polling.

Key Specifications

Pinout & Package

W29N08GVSIAA uses a 48-pin TSOP1 package (12 mm × 20 mm, package code S), with all Vcc and Vss pins requiring direct connection to power/ground per datasheet layout rules. N.C. pins are unconnected internally; DNU pins must remain floating.

FAQ

What is the operating voltage range for W29N08GVSIAA?

W29N08GVSIAA operates from 2.7V to 3.6V on a single Vcc supply, with all DC and AC specifications guaranteed across this range. This allows direct integration into 3.3V systems without regulators or level shifters, and maintains full functionality down to 2.7V during brown-out conditions common in industrial power rails.

Does W29N08GVSIAA support hardware write protection?

Yes, W29N08GVSIAA includes a dedicated #WP (Write Protect) pin that, when driven low, disables all program and erase operations-including block erase, page program, and copy-back-regardless of command sequence. This provides fail-safe protection against corruption during power-up/down or ESD events.

What NAND interface standard does W29N08GVSIAA comply with?

W29N08GVSIAA implements the ONFI 1.0–compatible command set and timing protocol, including standard commands (00h, 30h, 80h, 10h, 60h, D0h) and extended features like cache read (31h), two-plane operations, and copy-back (35h/85h). It does not require ONFI-specific initialization but remains interoperable with ONFI-aware controllers.

How is endurance specified for W29N08GVSIAA, and what ECC is required?

W29N08GVSIAA guarantees 100,000 program/erase cycles when used with 1-bit-per-528-byte ECC correction, as defined in the datasheet's endurance note. This reflects real-world SLC behavior under typical error-correction schemes used in Linux MTD/UBI or vendor FTL implementations-not a theoretical maximum.

What package type is used for W29N08GVSIAA, and are all pins electrically functional?

W29N08GVSIAA uses a 48-pin TSOP1 package (package code S), with 24 functional I/O and control pins (including #CE, #RE, #WE, CLE, ALE, #WP, RY/#BY, and I/O[0–7]), plus multiple Vcc and Vss pins requiring connection. N.C. and DNU pins are not internally bonded and must be left unconnected per datasheet layout guidance.
