Product details
Overview
S29GL064S90FHI040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, and 65-nm MIRRORBIT™ technology. It features uniform 32-Kword (64-KB) sectors, on-chip ECC for single-bit error correction, and industrial temperature range (–40°C to +85°C). Used in boot code storage for embedded controllers and firmware update storage in industrial gateways.
For engineers reviewing the S29GL064S90FHI040 datasheet, S29GL064S90FHI040 pinout, S29GL064S90FHI040 application, or S29GL064S90FHI040 equivalent, key selection criteria include sector architecture (uniform vs. boot), VIO voltage flexibility (1.65 V to VCC), hardware reset (RESET#) and ready/busy (RY/BY#) signaling, and secure silicon region programmability.
Technical Context
This device implements a parallel interface with 16-bit data bus (BYTE# configurable for 8-bit mode), JEDEC-compliant command set, and CFI support for host auto-identification. It uses hot-electron injection for programming and hot-hole assisted erase per sector.
Hardware-level protection includes WP#/ACC pin-based first/last sector lock, low-VCC write inhibit, and persistent sector protection via lock register. Erase and program suspend/resume enable concurrent read operations during background flash operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 words × 16-bit), organized as 128 uniform 64-KB sectors |
| Access Time | 70 ns - enables direct execution (XIP) from flash in real-time microcontroller boot paths |
| VIO Range | 1.65 V to VCC - supports mixed-voltage I/O interfacing without level shifters |
| ECC Capability | On-die hardware single-bit error correction - eliminates need for external ECC logic in safety-critical firmware storage |
| Endurance | 100,000 erase cycles per sector - suitable for field-updatable firmware with infrequent but critical reprogramming |
| Data Retention | 20 years typical - ensures long-term reliability in unattended industrial equipment |
| Temperature Range | –40°C to +85°C (Industrial) - validated for deployment in factory automation PLCs and motor drives |
Pinout & Package
Package: 48-lead TSOP (Type I, standard pitch, 12 mm × 20 mm × 1.2 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 64-Mb addressing (A0–A20 for word access; A21 selects upper/lower byte when BYTE# active) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; direction controlled by WE# and OE#; BYTE# enables 8-bit mode using DQ0–DQ7 only |
| CE# | Chip Enable | Active-low chip select; device enters standby when CE# high; required assertion for all read/write/erase commands |
| OE# | Output Enable | Active-low control for data bus output driver; used during read cycles to gate output without disabling chip |
| WE# | Write Enable | Active-low strobe for command latching and write operations; initiates internal command execution on rising edge |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing erase/program and returns device to reading state; tied to system reset for boot recovery |
| RY/BY# | Ready/Busy Output | Open-drain status signal; low = operation in progress; high = ready - replaces software polling for deterministic timing |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware lock of first/last sector; high + elevated voltage = accelerated programming mode for production line throughput |
| BYTE# | Bus Width Select | Low = 16-bit mode; high = 8-bit mode (DQ0–DQ7 only); enables compatibility with 8-bit microcontrollers |
| VIO | I/O Supply Voltage | Independent 1.65–VCC input setting logic thresholds for all address/data/control pins - decouples I/O voltage from core VCC |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory-programmable area with permanent lock - stores immutable device ID, calibration data, or cryptographic keys |
| Program/Erase Suspend | Pause active programming or erasing to service interrupts or read other sectors - enables real-time OS coexistence without flash stalls |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts firmware update time by ~50% in host-controlled writes |
| CFI Compliance | JEDEC-standard Common Flash Interface - allows generic flash drivers to auto-detect geometry, timings, and command sets at boot |
| Hardware Sector Protection | Configurable lock of any sector combination via persistent or password-protected registers - prevents accidental overwrite of bootloader or configuration sectors |

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 |
|---|---|---|---|
| S29GL064S90TFI020 | Same die, 90 ns access time, 56-pin TSOP package, no VIO pin (fixed 3.0 V I/O) | Lacks VIO flexibility and secure silicon region; lower performance margin for XIP | Select only if board layout requires 56-pin TSOP and I/O voltage is fixed at 3.0 V |
| S29GL064S10TFI020 | Same die, 100 ns access time, 56-pin TSOP, industrial temp, no VIO or secure silicon | No hardware ECC, no suspend/resume, no password protection - reduced security and real-time capability | Acceptable only for cost-sensitive, non-safety-critical firmware storage with relaxed timing |
Compared with S29GL064S90FHI040, the alternatives lack VIO voltage independence, secure silicon region, and hardware ECC - making them unsuitable for safety-certified, mixed-voltage, or long-life industrial deployments where data integrity and flexible I/O are mandatory.

FAQ
What is the function of the VIO pin on S29GL064S90FHI040?
The VIO pin sets the input threshold and output drive voltage for all address, control, and data pins independently of VCC. It accepts 1.65 V to VCC, enabling direct interfacing with 1.8 V or 2.5 V microcontrollers without external level shifters. This decoupling simplifies mixed-voltage board design and reduces BOM count.
Does S29GL064S90FHI040 support both 8-bit and 16-bit data bus modes?
Yes. When BYTE# is high, the device operates in 8-bit mode using only DQ0–DQ7; when BYTE# is low, it operates in full 16-bit mode. This dual-mode capability allows reuse of the same flash across 8-bit legacy MCUs and 16-bit upgrade paths without PCB redesign.
How does the Secure Silicon Region differ from standard sectors?
The Secure Silicon Region is a dedicated 128-word (256-byte) sector that can be permanently locked at factory or by customer via command sequence. Once locked, no further writes or erases are possible - unlike standard sectors protected by software registers, which remain reconfigurable.
Is hardware ECC enabled by default, and what does it correct?
Yes, internal ECC is always active during read operations. It detects and corrects any single-bit error per 512-bit word (i.e., per 64-byte chunk), eliminating soft errors caused by alpha particles or voltage fluctuations. No host-side ECC calculation or overhead is required.
