Product details
Overview
W29GL128CL9B 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 read access, and single 3.0 V supply (2.7–3.6 V). It supports byte/word mode via #BYTE pin, includes hardware write protection (#WP/ACC), and delivers >100,000 program/erase cycles for embedded boot code and firmware storage in industrial controllers.
For engineers reviewing the W29GL128CL9B TR datasheet, W29GL128CL9B TR pinout, W29GL128CL9B TR application, or W29GL128CL9B TR equivalent, key selection criteria include TSOP-56 package compatibility, CFI interface support for firmware abstraction, deep power-down mode (5 µA), and sector erase suspend/resume capability for real-time system responsiveness.
Technical Context
This device implements a parallel asynchronous interface with dedicated control pins (#CE, #OE, #WE, #RESET, RY/#BY) and supports both byte (DQ[7:0]) and word (DQ[15:0]) data widths selected by #BYTE. Its architecture features 128 uniform 128 KB sectors, a 32-word write buffer to reduce multi-word programming time, and an 8-word page read buffer enabling fast sequential access within a 16-byte page.
Functional operation relies on command-based instruction sequences written to specific address/data latches - including Read ID, Sector Erase, Buffer Write, and CFI Query - with status monitored via DQ5 polling or RY/#BY output. Enhanced Variable IO (EVIO) allows input/output voltage thresholds to track EVIO pin voltage (1.65 V to VCC), ensuring interoperability across mixed-voltage systems.

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, PLCC-56 package; no EVIO or deep power-down mode | Lacks sector suspend/resume and CFI-enhanced query; requires firmware adaptation for ID detection | Preferred where PLCC socketing is mandatory and low-power modes are unused |
| MX29GL128FHT2I-90G | 128 Mbit, 90 ns access, 3.0 V, TSOP-56; supports CFI but no Secured Silicon Sector or #WP/ACC acceleration | No factory-programmable serial number or hardware-accelerated programming; lower production throughput | Selected when cost sensitivity outweighs secure identity and accelerated programming needs |
Compared with W29GL128CL9B TR, S29GL128S11TFI010 offers socket compatibility but sacrifices real-time erase suspend and low-power operation, while MX29GL128FHT2I-90G matches speed and package but omits secured silicon and VHH acceleration - making W29GL128CL9B TR optimal for secure, high-throughput, and power-constrained embedded designs.

FAQ
What is the package type and pin count of the W29GL128CL9B TR?
The W29GL128CL9B TR uses a 56-pin TSOP-I (Thin Small Outline Package) with 14 mm × 20 mm body dimensions and standard parallel Flash pinout. This package is compatible with JEDEC MO-142AB and supports surface-mount reflow assembly. The 'L9B' suffix specifically denotes the TSOP-56 variant with lead-free finish and tape-and-reel packaging (TR), confirmed in Winbond's ordering guide revision H.
Does the W29GL128CL9B TR support both 8-bit and 16-bit data bus configurations?
Yes, the W29GL128CL9B TR supports configurable bus width via the #BYTE pin: when #BYTE = VIH, it operates in 16-bit word mode using A22–A0 and DQ15–DQ0; when #BYTE = VIL, it operates in 8-bit byte mode using A22–A-1 (with DQ15 repurposed as A-1) and DQ7–DQ0. This dual-mode capability allows seamless integration into both legacy 8-bit microcontrollers and modern 16-bit processors without hardware redesign.
How does the Secured Silicon Sector function in the W29GL128CL9B TR?
The W29GL128CL9B TR includes a dedicated 256-byte Secured Silicon Sector that can be factory-programmed with a unique 16-byte electronic serial number or customer-programmed for permanent device identification. Once locked, this sector is immune to erase commands and provides tamper-resistant storage for cryptographic keys or calibration data - a feature absent in most commodity parallel Flash devices and critical for medical and automotive certification.
What is the purpose of the EVIO pin on the W29GL128CL9B TR?
The EVIO (Enhanced Variable I/O) pin on the W29GL128CL9B TR sets the reference voltage for all input thresholds and output drive levels, allowing the device to interface reliably with mixed-voltage systems. When EVIO is biased between 1.65 V and VCC, address, control, and data pins automatically adapt their logic levels - eliminating external level shifters in designs combining 1.8 V, 2.5 V, or 3.3 V controllers with the 3.0 V W29GL128CL9B TR.
Can the W29GL128CL9B TR perform erase operations while servicing read requests?
Yes, the W29GL128CL9B TR supports Erase Suspend/Resume functionality: issuing an Erase Suspend command pauses an ongoing sector erase within ≤20 µs, allowing immediate high-priority reads or writes to other unerased sectors. After completion, an Erase Resume command restarts the suspended erase from the exact point of interruption - a capability essential for real-time embedded systems requiring deterministic latency guarantees during firmware updates.
