Product details
Overview
W29N01HWSINF 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 blocks of 64 pages each (2,112 bytes/page), with 25μs random read access and 250μs typical page program time. It supports x8 bus width in 48-pin TSOP1 package and targets embedded code storage, firmware boot images, and media buffering in space-constrained industrial systems.
For engineers reviewing the W29N01HWSINF TR datasheet, W29N01HWSINF TR pinout, W29N01HWSINF TR application, or W29N01HWSINF TR equivalent, this page delivers verified electrical specs, validated TSOP1 pin mapping, confirmed SLC endurance (100,000 P/E cycles), real-world timing behavior (tR = 25μs, tPROG = 250μs), and functionally matched alternatives for industrial-temperature NAND replacement.
Technical Context
The W29N01HWSINF TR implements standard ONFI-compatible NAND command protocol using five dedicated control signals (#CE, #RE, #WE, CLE, ALE) and multiplexed I/O[0–7] for command, address, and data transfer. Its internal architecture includes a 2,112-byte data register, column/row decoders, high-voltage generator, and status register - enabling full support for PAGE READ (00h/30h), PAGE PROGRAM (80h/10h), BLOCK ERASE (60h/D0h), COPY BACK, and READ STATUS (70h) operations.
It operates across -40°C to +85°C (Industrial grade), features hardware write protection via #WP, open-drain RY/#BY for operation status monitoring, and requires no external Vpp supply. The device uses 4-bit/528-byte ECC for its 100,000-cycle endurance rating and guarantees 10-year data retention under specified conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 G-bit / 128 MB total capacity; enables compact firmware/image storage without external expansion. |
| Supply Voltage | 1.7 V to 1.95 V; compatible with modern low-voltage SoC I/O domains and reduces system power overhead. |
| Page Size | 2,112 bytes (2,048B main + 64B spare); spare area reserved for ECC metadata and bad-block management. |
| Block Size | 135,168 bytes (64 × 2,112B); defines minimum erasable unit for wear leveling and firmware update partitioning. |
| Random Read Time | 25 μs max; determines latency for small-code fetches (e.g., boot loader startup, interrupt handlers). |
| Page Program Time | 250 μs typical; sets minimum interval between successive page writes in logging or configuration update use cases. |
| Endurance | 100,000 program/erase cycles (with 4-bit/528-byte ECC); supports long-life industrial logging and field-updatable firmware. |
| Data Retention | 10 years at 85°C; ensures reliability in unpowered storage during extended deployment or transport. |
Pinout & Package
W29N01HWSINF TR is supplied in 48-pin TSOP1 (Package Code S), 12 mm × 20 mm footprint, with all Vcc and Vss pins requiring connection per datasheet requirement. Pin functions are validated per Figure 3-1 and Table 3.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low global enable; places device in standby (10 μA) when high, enabling multi-chip select arbitration. |
| #RE | Read Enable | Controls serial data output timing; valid data appears after tREA (25 ns) from falling edge. |
| #WE | Write Enable | Latches commands, addresses, and data on rising edge; defines setup/hold timing windows for reliable bus interface. |
| CLE | Command Latch Enable | Signals I/O bus content as command byte (e.g., 00h, 80h); required before issuing any NAND operation. |
| ALE | Address Latch Enable | Signals I/O bus content as address byte; used for column/row addressing across four cycles. |
| RY/#BY | Ready/Busy Output | Open-drain status indicator; low during active program/erase/read, enabling polling or interrupt-driven flow control. |
| #WP | Write Protect Input | Hardware lock: drives all program/erase operations inactive when pulled low; prevents accidental corruption. |
| I/O[0–7] | Bidirectional Data Bus | Multiplexed path for commands (8-bit), addresses (4×8-bit), and data (2,112-byte pages); eliminates separate address/data buses. |
Key Features
| Feature | Design Value |
|---|---|
| SLC NAND Architecture | Guarantees deterministic 100,000 P/E cycles and 10-year retention - critical for industrial firmware storage where MLC/TLC would fail prematurely. |
| Standard NAND Command Set | Full ONFI-compatible instruction set (00h/30h read, 80h/10h program, 60h/D0h erase) ensures drop-in compatibility with existing NAND controllers and drivers. |
| Copy Back Operation | Enables page-to-page relocation within same die without host RAM buffering - reduces wear during garbage collection and improves system-level write efficiency. |
| Hardware Write Protection | #WP pin provides physical, non-volatile lock against unintended firmware overwrite - essential for field-deployed devices with remote update capability. |
| Low-Power Standby | 10 μA CMOS standby current minimizes quiescent drain in battery-backed or energy-harvesting applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SLC NAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MT29F1G08ABAEAH4-IT:E | 1 G-bit SLC NAND in 48-ball VFBGA; 25 μs random read, but 300 μs typical page program; requires 1.7–1.95 V. | Smaller footprint (8 mm × 9 mm vs. TSOP1's 12 mm × 20 mm); no TSOP1 option available. | Select when board space is constrained and BGA assembly is supported; verify #WP and RY/#BY timing alignment with host controller. |
| TC58CVG1S3HRAIJ | 1 G-bit SLC NAND in 48-pin TSOP1; 25 μs random read, 200 μs typical page program; 2.7–3.6 V supply only. | Higher voltage requirement incompatible with 1.8 V SoCs; identical pinout but different DC/AC timing margins. | Use only in legacy 3.3 V designs; not suitable for direct replacement in 1.8 V systems like those targeting W29N01HWSINF TR. |
Compared with MT29F1G08ABAEAH4-IT:E and TC58CVG1S3HRAIJ, the W29N01HWSINF TR uniquely combines TSOP1 packaging, 1.8 V operation, and 250 μs program time - making it the only drop-in option for space-aware, low-voltage industrial boards requiring proven manufacturability and thermal robustness.

FAQ
What is the operating temperature range for W29N01HWSINF TR?
W29N01HWSINF TR is rated for Industrial temperature range: -40°C to +85°C. This specification is confirmed in Section 2 (Features) and Table 15.1 (Ordering Information) of the official datasheet. The part number suffix "INF" explicitly denotes Industrial grade, and thermal performance is validated across the full range per JEDEC JESD22-A108 testing protocols. W29N01HWSINF TR maintains full functionality and timing compliance within these limits.
Does W29N01HWSINF TR support x16 bus width?
No, W29N01HWSINF TR does not support x16 bus width. The "S" in the part number denotes 48-pin TSOP1 package, which is x8-only per Figure 3-1 and Section 3.1. While the broader W29N01HZ/WxxNF family includes x16 variants in VFBGA packages (e.g., "D" and "B" codes), the W29N01HWSINF TR variant is strictly x8. Attempting x16 operation will result in undefined behavior and bus contention.
What is the exact page size and spare area allocation for W29N01HWSINF TR?
W29N01HWSINF TR has a page size of 2,112 bytes: 2,048 bytes for main data storage and 64 bytes for spare area. This is explicitly defined in Section 2 (Features) and Section 6.1 (Array Organization). The spare area is reserved for ECC metadata, logical-to-physical mapping, and bad-block flags - and is inaccessible to host software during normal read/write operations.
Is W29N01HWSINF TR pin-compatible with other Winbond W29N01HZ-series parts?
W29N01HWSINF TR shares identical pinout and signal definitions with all other 48-pin TSOP1 variants in the W29N01HZ/WxxNF family (e.g., W29N01HWSINJ TR), as confirmed by Figure 3-1 and Table 3.1. However, it is not pin-compatible with VFBGA variants (48-ball "D", 63-ball "B") due to differing ball/pin counts and layouts. Electrical timing and command behavior remain consistent across the family.
What ECC strength is required to achieve the rated 100,000 P/E cycles for W29N01HWSINF TR?
A 4-bit error correction per 528-byte sector is required to achieve the rated 100,000 program/erase cycles for W29N01HWSINF TR. This is stated in the footnote to Section 2 (Features): "Endurance specification is based on 4bit/528 byte ECC." Host controller or NAND flash controller must implement BCH or RS decoding capable of correcting up to 4 bits per sector to meet the datasheet's endurance guarantee.
