Product details
Overview
S29GL064S80TFV040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, industrial temperature range (–40°C to +85°C), and TSOP-48 packaging - used for boot code storage in embedded controllers and firmware updates in industrial HMIs.
For engineers reviewing the S29GL064S80TFV040 datasheet, S29GL064S80TFV040 pinout, S29GL064S80TFV040 application, or S29GL064S80TFV040 equivalent, key selection criteria include sector architecture (uniform vs. boot), VIO voltage flexibility (1.65 V to VCC), JEDEC software compatibility, and Secure Silicon Region programmability for device identity binding.
Technical Context
This device implements a parallel asynchronous interface with separate CE#, OE#, and WE# controls, supporting both 16-bit word and 8-bit byte modes via BYTE# input. Its MIRRORBIT™ 65-nm process enables hot-hole erase and hot-electron programming with 100,000 erase cycles per sector and 20-year data retention.
The architecture includes dedicated hardware features: RESET# for operation abort and system reset synchronization, RY/BY# for cycle completion signaling, and WP#/ACC for factory- or field-programmable first/last sector protection independent of software lock settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 words × 16 bits), organized as 128 uniform 64-KB sectors |
| Access Time | 70 ns - determines minimum read cycle duration for synchronous host interface timing |
| Write Buffer Size | 128-word (256-byte) - reduces multi-word programming overhead by batching writes |
| ECC Support | On-die hardware ECC - corrects single-bit errors transparently during read operations |
| VIO Range | 1.65 V to VCC - allows I/O voltage independence from core supply for mixed-voltage system interfacing |
| Endurance | 100,000 erase cycles per sector - defines maximum field reprogramming count before wear-out |
| Data Retention | 20 years typical at 85°C - specifies guaranteed data integrity under industrial thermal stress |
Pinout & Package

| A0–A21 | Address Inputs | 22-bit address bus selecting one of 4,194,304 words (16-bit wide) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data path; BYTE# enables 8-bit mode by masking DQ8–DQ15 |
| CE# | Chip Enable | Active-low chip select; device enters standby when deasserted |
| OE# | Output Enable | Active-low control for data bus output drivers during read cycles |
| WE# | Write Enable | Active-low strobe latching address/data for program/erase command execution |
| RESET# | Hardware Reset | Active-low signal terminating ongoing operations and returning device to read mode |
| RY/BY# | Ready/Busy Output | Open-drain status indicator: low = operation in progress, high = ready |
| WP#/ACC | Write Protect / Accelerated Program | Low = protects first/last sector; high-voltage = enables accelerated programming |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory- or customer-lockable area with permanent electronic serial number for secure device identification |
| Program/Erase Suspend | Allows host to pause active programming or erasing to read/write other sectors - critical for real-time firmware update scenarios |
| Unlock Bypass Mode | Reduces multi-word programming command overhead from 4 to 2 write cycles - cuts host CPU intervention time by 50% |
| Advanced Sector Protection | Combines persistent lock bits and password-based sector locking - prevents unauthorized firmware modification without physical access or valid credentials |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFV040 | 90 ns access time; same density, package, and feature set | Lower performance grade suitable for cost-sensitive non-real-time firmware storage | Select when 70 ns timing margin is unnecessary and BOM cost reduction is prioritized |
| MX29GL640EHTI-90G | Macronix part with 90 ns access, no Secure Silicon Region, CFI-compatible but lacks password sector protection | Acceptable for basic firmware storage where cryptographic identity binding is not required | Choose only if Secure Silicon Region and persistent sector lock bits are not mandated by system security policy |
Compared with S29GL064S80TFV040, the -90 variant trades 20 ns speed for lower cost without functional loss, while the Macronix alternative omits secure identity and advanced protection - making it unsuitable for safety-critical or tamper-resistant designs.

FAQ
What is the function of the WP#/ACC pin on S29GL064S80TFV040?
The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector regardless of software lock settings; when driven to elevated voltage (typically 9 V), it enables accelerated programming for faster production-line firmware loading. This pin operates independently of VCC and remains active during power transitions.
Does S29GL064S80TFV040 support byte-wide data access?
Yes - the device supports 8-bit mode using the BYTE# input. When BYTE# is asserted low, DQ0–DQ7 become active for byte-level reads/writes while DQ8–DQ15 are disabled. This enables compatibility with 8-bit microcontrollers without external data bus multiplexing logic.
How does the Secure Silicon Region differ from standard flash sectors?
The Secure Silicon Region is a dedicated 128-word (256-byte) area that can be permanently locked at factory or by the user. Once protected, no further writes or erases are possible - even with valid passwords or unlock sequences. It contains a factory-programmed 8-word electronic serial number accessible only via specific command sequences.
Can S29GL064S80TFV040 operate with VIO = 1.8 V while VCC = 3.0 V?
Yes - the VIO input sets all I/O voltage thresholds independently of VCC. With VIO = 1.8 V, address, control, and data pins operate at 1.8 V logic levels while the core remains powered at 3.0 V. This allows seamless interfacing with 1.8 V FPGAs or ASICs without level shifters, provided VIO stays within 1.65 V to VCC.
