Product details
Overview
W29GL064CT7S from Winbond is a 64 Mbit (8 MB) parallel NOR Flash memory with uniform 64 KB sectors, 70 ns random access time, and 25 ns page read speed, operating from a single 3.0 V supply (2.7–3.6 V). It supports byte/word configuration via #BYTE pin, hardware write protection and acceleration via #WP/ACC, and CFI-compliant identification for firmware-transparent system integration in embedded boot code storage.
For engineers reviewing the W29GL064CT7S datasheet, W29GL064CT7S pinout, W29GL064CT7S application, or W29GL064CT7S equivalent, key selection criteria include sector architecture (H/L vs T/B), deep power-down current (≤1 µA), erase/program endurance (>100,000 cycles), data retention (>20 years), and EVIO voltage flexibility (1.65 V to VCC) for mixed-voltage interface design.
Technical Context
The W29GL064CT7S implements a parallel asynchronous interface with dedicated #CE, #OE, and #WE controls, supporting both byte (x8) and word (x16) data bus modes selected by the #BYTE pin. Its internal architecture includes a 16-word write buffer and 8-word page read buffer to accelerate sequential programming and burst reads.
It features dual-sector protection mechanisms - Enhanced Sector Protect using Dynamic (volatile) and Individual (non-volatile) lock registers, plus a factory-programmable 256-byte Secured Silicon Sector with electronic serial number. CFI mode enables standardized parameter interrogation without vendor-specific firmware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 MB); supports boot code, firmware, and configuration storage in resource-constrained embedded systems. |
| Access Time | 70 ns random read; ensures fast instruction fetch for microcontroller boot sequences without wait states. |
| Page Read Speed | 25 ns; reduces latency during sequential code execution or table lookups in real-time applications. |
| Erase/Program Endurance | >100,000 cycles; suitable for field-upgradable firmware with frequent reprogramming in industrial controllers. |
| Data Retention | >20 years at 85°C; guarantees long-term reliability in automotive and telecom infrastructure deployments. |
| Deep Power-Down Current | ≤1 µA; enables ultra-low-power sleep modes in battery-backed or energy-harvesting edge devices. |
| Supply Voltage Range | 2.7–3.6 V; compatible with standard 3.3 V logic rails while tolerating brown-out conditions down to 2.7 V. |
Pinout & Package
W29GL064CT7S is packaged in a 48-pin TSOP (12 × 20 mm), configured as a Bottom/Top Boot Sector variant per ordering code T7S. Pin functions are defined for parallel x8/x16 operation with hardware reset (#RESET), ready/busy status (RY/#BY), and enhanced variable I/O control (EVIO).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| #CE | Chip Enable | Active-low chip select; enables device for read/write when asserted with valid #OE/#WE timing. |
| #OE | Output Enable | Controls output buffer tri-state; must be low during read to drive DQ[15:0] with valid data. |
| #WE | Write Enable | Latches address/data on rising edge; initiates program/erase commands when combined with #CE. |
| #BYTE | Bus Width Select | Low = x8 mode (A21–A−1, DQ[7:0]); High = x16 mode (A21–A0, DQ[15:0]). |
| #WP/ACC | Write Protect / Acceleration | VIL protects top/bottom two sectors; VIH + VHH enables accelerated programming for production throughput. |
| RY/#BY | Ready/Busy Status | Open-drain output; low during active program/erase, high when operation completes or in read mode. |
| EVIO | Enhanced Variable I/O Supply | Sets input/output voltage thresholds (1.65 V to VCC); allows interfacing with mixed-voltage host logic. |
| DQ15/A−1 | Bi-directional Data / Address | In x8 mode: A−1 (LSB address); in x16 mode: DQ15 (MSB data); eliminates need for external address multiplexing. |
Key Features
| Feature | Design Value |
|---|---|
| 16-Word Write Buffer | Reduces total programming time for multi-word updates by up to 4× versus single-word writes. |
| Secured Silicon Sector | 256-byte factory-lockable region with 16-byte electronic serial number for secure device identity and anti-cloning. |
| CFI Compliance | Enables automatic detection of device geometry, timing, and command sets via standardized query mode-no firmware modification required. |
| Enhanced Sector Protect | Combines volatile DPB and non-volatile IPB registers to support dynamic field reconfiguration and permanent sector locking. |
| Erase/Program Suspend | Allows interrupting long erase/program operations to service high-priority reads, then resuming without data loss. |
Applications
| Industrial PLC Firmware Storage | Automotive Infotainment Boot Code |

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 |
|---|---|---|---|
| S29GL064S90TFI010 | 64 Mbit, 90 ns access, 3.0 V, 56-pin TSOP; lacks deep power-down mode and EVIO support. | Higher access latency limits use in time-critical boot paths; no low-power sleep mode for always-on networking gear. | Select when legacy board layout uses 56-pin footprint and deep power-down is unnecessary. |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, 3.0 V, 48-pin TSOP; supports CFI but no Secured Silicon Sector or erase suspend/resume. | No hardware-based device identity or field-interruptible erase-unsuitable for medical or secure OTA applications. | Choose for cost-sensitive industrial HMI designs where security and suspend features are not required. |
Compared with S29GL064S90TFI010 and MX29GL640EHTI-90G, the W29GL064CT7S delivers faster 70 ns access, deep power-down for energy-constrained nodes, and Secured Silicon Sector for traceable device identity-making it optimal for next-generation embedded systems demanding performance, security, and power efficiency.

FAQ
What is the package type and pin count for W29GL064CT7S?
The W29GL064CT7S uses a 48-pin TSOP (Thin Small Outline Package) with dimensions 12 mm × 20 mm. This package corresponds to the Bottom/Top Boot Sector configuration indicated by the 'T7S' suffix in the part number, and is verified in Winbond's official datasheet revision H, Figure 3-3-4 and Table 10-1.
Does W29GL064CT7S support both x8 and x16 data bus widths?
Yes, W29GL064CT7S supports configurable x8 or x16 operation via the #BYTE pin: when #BYTE = VIL, it operates in x8 mode with DQ[7:0] active and A−1 used as LSB address; when #BYTE = VIH, it operates in x16 mode with DQ[15:0] active and standard A21–A0 addressing. This is confirmed in Section 5 (Pin Description) and Table 7-1 of the datasheet.
What is the purpose of the EVIO pin on W29GL064CT7S?
The EVIO (Enhanced Variable I/O) pin on W29GL064CT7S sets the voltage threshold for all address, control, and data I/O pins, allowing operation across 1.65 V to VCC. This enables interoperability with mixed-voltage host systems-for example, interfacing with 1.8 V logic while powered from 3.3 V-without level shifters. The function is documented in Section 2 (Features) and Section 5 (Pin Description) of the datasheet.
How does the Secured Silicon Sector work in W29GL064CT7S?
The Secured Silicon Sector in W29GL064CT7S is a dedicated 256-byte region that can be factory-locked or customer-lockable. It stores a unique 16-byte electronic serial number and supports permanent, tamper-resistant identification. Once locked, it cannot be erased or rewritten. This feature is detailed in Section 7.4 and Table 7-12 of the W29GL064C datasheet.
What are the key timing differences between W29GL064CT7S and older 90 ns parallel Flash devices?
W29GL064CT7S offers 70 ns random access time and 25 ns page read speed-significantly faster than legacy 90 ns parts like S29GL064S90TFI010. Its accelerated programming (2× industry standard) and faster erase (1.5×) reduce firmware update windows. These values are specified in Section 1 (General Description) and Table 8-5 of the datasheet.
