Product details
Overview
W29GL128CL9T TR from Winbond is a 128-Mbit (16 MB) parallel NOR Flash memory IC with uniform 128k-byte sectors, 90 ns random access time, 25 ns page access time, and single 3.0 V supply (2.7–3.6 V) operation. It supports byte/word mode via #BYTE pin, includes a 32-word write buffer and 8-word page read buffer, and is used in embedded boot code storage, firmware update storage, and BIOS/UEFI nonvolatile memory in industrial control and networking equipment.
For engineers reviewing the W29GL128CL9T TR datasheet, W29GL128CL9T TR pinout, W29GL128CL9T TR application, or W29GL128CL9T TR equivalent, key selection considerations include sector protection granularity, deep power-down current (≤1 µA), CFI interface compatibility, EVIO voltage flexibility (1.65–VCC), and hardware write-protection via #WP/ACC pin.
Technical Context
This device implements a parallel asynchronous interface with dedicated #CE, #OE, and #WE controls, supporting both byte (x8) and word (x16) data bus configurations via the #BYTE pin. Its architecture features 128 uniform sectors of 128 KB each, a secured silicon sector for permanent device identification, and dual-sector protection mechanisms-individual non-volatile lock bits and dynamic volatile protection.
Functional operation relies on command-based instruction sets executed via address/data latching on falling/rising edges of #WE or #CE. Embedded algorithms handle program, sector erase, chip erase, suspend/resume, and write buffer programming-all monitored via DQ5 polling or RY/#BY status output. CFI mode enables host system auto-configuration through standardized geometry and interface queries.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL128S11TFI010 | 128 Mbit, 110 ns access, 3.0 V, 64-ball LFBGA only; no deep power-down mode | Lacks deep power-down (ICC = 30 µA vs. 1 µA); no EVIO pin-requires fixed 3.3 V I/O | Choose if board uses LFBGA64 footprint and power budget allows higher standby current |
| MX29GL128FTEI-90G | 128 Mbit, 90 ns access, 3.0 V, TSOP56; supports CFI but no Secured Silicon Sector | No factory/customer-lockable security sector; lacks #WP/ACC acceleration function | Choose if security sector and programming acceleration are not required; lower cost alternative |
Compared with W29GL128CL9T TR, S29GL128S11TFI010 trades ultra-low deep power-down for LFBGA-only availability, while MX29GL128FTEI-90G omits security and acceleration features but matches access speed and TSOP packaging-making it suitable for cost-sensitive, non-secure boot applications.

FAQ
What is the pin count and package type of the W29GL128CL9T TR?
The W29GL128CL9T TR uses a 56-pin TSOP-I (Thin Small Outline Package) with 14 mm × 20 mm dimensions, RoHS-compliant and lead-free. This package matches industry-standard parallel Flash footprints and supports socket-based prototyping and legacy PCB designs without layout changes.
Does the W29GL128CL9T TR support both x8 and x16 data bus widths?
Yes, the W29GL128CL9T TR supports configurable bus width via the #BYTE pin: when #BYTE = VIH, it operates in 16-bit word mode (A22–A0 addressing); when #BYTE = VIL, it operates in 8-bit byte mode (A22–A-1, with DQ15 serving as A-1). This flexibility allows seamless integration into 8-bit or 16-bit microcontroller interfaces.
What is the purpose of the #WP/ACC pin on the W29GL128CL9T TR?
The #WP/ACC pin on the W29GL128CL9T TR serves dual functions: at VIL, it hardware-protects the top or bottom sector regardless of software protection settings; at VIH with VHH applied, it accelerates internal programming timing-reducing production burn-in time. This pin enables both field safety and manufacturing throughput optimization.
How does the Secured Silicon Sector function in the W29GL128CL9T TR?
The Secured Silicon Sector in the W29GL128CL9T TR is a dedicated 128-word (256-byte) region that can be permanently programmed and locked either at factory (for unique serial numbers) or by the customer (for cryptographic keys). Once locked, it cannot be erased or rewritten-even with full chip erase-ensuring tamper-resistant identity storage.
Is CFI (Common Flash Interface) supported by the W29GL128CL9T TR?
Yes, the W29GL128CL9T TR fully supports CFI mode, allowing host systems to auto-detect memory geometry, timing parameters, and command sets via standardized query commands. This eliminates hardcoded Flash driver dependencies and simplifies firmware portability across different NOR Flash vendors and densities.
