Product details
Overview
W29GL128CL9T 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 read access, and single 3.0 V supply (2.7–3.6 V) operation. It supports byte/word mode via #BYTE pin, features hardware write protection via #WP/ACC, and delivers embedded erase/program operations with suspend/resume capability for real-time firmware updates in industrial controllers.
For engineers reviewing the W29GL128CL9T datasheet, W29GL128CL9T pinout, W29GL128CL9T application, or W29GL128CL9T equivalent, key selection criteria include sector architecture compatibility, CFI interface support, deep power-down current (≤1 µA), EVIO voltage flexibility (1.65–VCC), and TSOP-56 package footprint for legacy board reuse.
Technical Context
This device implements a uniform 128-sector architecture (each 128 KB), with dual-mode addressing (A22–A0 in word mode, A22–A-1 in byte mode) and EVIO-controlled I/O voltage referencing. Its instruction set includes Auto Select for manufacturer/device ID, CFI query mode, and secure silicon sector access using factory- or customer-programmable 256-byte lockable region.
Embedded algorithms handle chip/sector erase and buffer programming with status reporting via DQ5 toggling and RY/#BY output. Hardware reset (#RESET), ready/busy signaling, and #WP/ACC pin enable both acceleration (VHH applied) and top/bottom sector protection independent of software settings.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR Flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL128S11TFI010 | 128 Mbit, 110 ns access, 3.0 V, 56-pin TSOP; lacks EVIO and deep power-down mode | No voltage-flexible I/O; higher standby current (10 µA) limits battery-powered use | Choose for cost-sensitive designs where EVIO and ultra-low sleep current are not required |
| MX29GL128FHT2I-90G | 128 Mbit, 90 ns access, 3.0 V, 56-pin TSOP; supports CFI but no secured silicon sector | Missing factory-lockable 256-byte security region; no hardware-based serial number binding | Prefer when full CFI compatibility is needed but cryptographic identity storage is handled externally |
Compared with S29GL128S11TFI010 and MX29GL128FHT2I-90G, W29GL128CL9T uniquely combines 90 ns speed, EVIO voltage scaling, deep power-down, and secured silicon-making it optimal for space-constrained, battery-aware, and security-critical embedded systems requiring long-term firmware integrity.

FAQ
What is the operating voltage range for W29GL128CL9T?
W29GL128CL9T operates from 2.7 V to 3.6 V DC on VCC. Its EVIO pin accepts 1.65 V to VCC, allowing I/O logic levels to be independently scaled-enabling direct interfacing with 1.8 V or 2.5 V controllers without level shifters. This dual-voltage flexibility is confirmed in Section 8.2 and 7.2.20 of the datasheet.
Does W29GL128CL9T support CFI (Common Flash Interface)?
Yes, W29GL128CL9T fully supports CFI mode per JEDEC JESD68. Entering CFI mode via Auto Select command sequence (Table 7-9) returns standardized geometry, interface, and vendor-specific data-enabling OS-agnostic flash drivers to auto-detect density, sector layout, and command sets without hardcoded assumptions.
How does the secured silicon sector work in W29GL128CL9T?
The secured silicon sector in W29GL128CL9T is a dedicated 256-byte (128-word) region that can be permanently locked at factory (99h/89h codes) or by the customer post-production (19h/09h). Once locked, it stores immutable data such as electronic serial numbers or cryptographic keys-verified via dedicated read instructions in Table 7-2 and Section 7.4.
What is the purpose of the #WP/ACC pin on W29GL128CL9T?
The #WP/ACC pin on W29GL128CL9T serves dual roles: when pulled low, it hardware-protects the top or bottom sector regardless of software protection settings; when driven high with VHH (12 V), it accelerates programming time by >50%, improving throughput during system-level programming. Both functions are detailed in Sections 2, 5, and 7.2.21.
Can W29GL128CL9T perform read operations during an erase or program cycle?
Yes, W29GL128CL9T supports Erase Suspend and Program Suspend commands. When issued, the device pauses the active operation within 20 µs and enters Erase-Suspended Read mode-allowing reads or writes to non-erasing sectors. Resuming requires explicit Erase Resume or Program Resume, as defined in Sections 7.2.10 and 7.2.12.
