Winbond Electronics Corporation W29N01HZSINF TR

Overview

W29N01HZSINF TR from Winbond is a 1G-bit (128MB) Single-Level Cell (SLC) NAND Flash memory operating at 1.7–1.95V, organized into 1,024 erasable blocks of 135,168 bytes each (64 pages × 2,112 bytes), with 2,048-byte main data + 64-byte spare area per page. It supports x8/x16 bus width and is used for code shadowing, firmware storage, and media buffering in space-constrained embedded systems.

For engineers reviewing the W29N01HZSINF TR datasheet, W29N01HZSINF TR pinout, W29N01HZSINF TR application, or W29N01HZSINF TR equivalent, this page delivers verified electrical specs, TSOP1/VFBGA pin mapping, ONFI-compatible command set support, SLC endurance (100K P/E cycles), and industrial temperature operation (–40°C to +85°C).

Technical Context

The W29N01HZSINF TR 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 2,112-byte data register, column/row decoders, high-voltage generator, and status register accessible via READ STATUS (70h) command.

It executes full ONFI-aligned operations including PAGE READ (00h–30h), PAGE PROGRAM (80h–10h), BLOCK ERASE (60h–D0h), COPY BACK, RANDOM DATA INPUT/OUTPUT, and READ PARAMETER PAGE (ECh). Write protection is hardware-enforced via active-low #WP, and device readiness is signaled open-drain on RY/#BY.

Key Specifications

Pinout & Package

W29N01HZSINF TR is packaged in a 48-pin TSOP1 (12 mm × 20 mm, package code S), with all Vcc and Vss pins requiring connection per datasheet requirement. Pin functions are electrically identical across x8 and x16 variants; this variant uses x8 bus configuration.

FAQ

What is the operating voltage range for W29N01HZSINF TR?

The W29N01HZSINF TR operates from 1.7 V to 1.95 V. This narrow 1.8V nominal range ensures compatibility with modern low-power microcontrollers and SoCs without requiring additional voltage regulation. All DC and AC specifications-including 13 mA read current and 25 µs random read-are guaranteed across this full range. Operating outside this window may cause functional failure or accelerated wear.

Does W29N01HZSINF TR support ONFI commands?

Yes, W29N01HZSINF TR supports the standard ONFI command set, including PAGE READ (00h–30h), PAGE PROGRAM (80h–10h), BLOCK ERASE (60h–D0h), READ STATUS (70h), RESET (FFh), and extended commands like READ PARAMETER PAGE (ECh) and COPY BACK. These are fully documented in the datasheet's Command Table (Table 8.1) and validated for interoperability with ONFI-aware controllers.

What package type is used by W29N01HZSINF TR?

W29N01HZSINF TR uses a 48-pin TSOP1 package (12 mm × 20 mm, package code S), as confirmed in Section 3.1 and Figure 3-1 of the datasheet. It is not offered in VFBGA variants under this specific part number-only the SINF suffix denotes the TSOP1 industrial-grade version. Pin assignments match the x8 bus configuration shown in the 48-pin TSOP1 diagram.

How many program/erase cycles does W29N01HZSINF TR guarantee?

W29N01HZSINF TR guarantees 100,000 program/erase cycles when used with 4-bit-per-528-byte ECC, as specified in the Features section (page 7) and Electrical Characteristics (Table 10.7). This endurance rating applies across the full industrial temperature range (–40°C to +85°C) and is measured per block-not per page-ensuring predictable wear behavior in firmware update scenarios.

Is hardware write protection available on W29N01HZSINF TR?

Yes, W29N01HZSINF TR includes a dedicated active-low #WP (Write Protect) pin (Pin 37 in TSOP1). When held low, it disables all program and erase operations globally-regardless of command sequence-providing hardware-level immunity against firmware corruption due to software faults or ESD events. This function is detailed in Section 4.6 and Mode Selection Table (Table 7.1).
