Product details
Overview
S29GL064N90TFI040 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and operates across VIO = 1.65–3.6 V for flexible I/O voltage control - used in industrial control firmware storage and boot code retention.
For engineers reviewing the S29GL064N90TFI040 datasheet, S29GL064N90TFI040 pinout, S29GL064N90TFI040 application, or S29GL064N90TFI040 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, hardware reset (RESET#), Ready/Busy# status signaling, and support for Program/Erase Suspend & Resume operations in embedded systems.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It uses separate CE#, WE#, and OE# controls and supports both word (16-bit) and byte (8-bit via BYTE#) configurations.
The command interface complies fully with JEDEC JESD21-C and includes CFI (Common Flash Interface) for host auto-identification. Sector protection combines Persistent Sector Protection (PPB lock bit) and Password Sector Protection, while the Secured Silicon Sector provides 256-byte factory-locked identity space accessible only via dedicated command sequence.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words) - defines maximum firmware image size and boot partition capacity. |
| Access Time | 90 ns at VCC = 2.7–3.6 V - enables direct execution from flash (XIP) in real-time microcontroller applications. |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over product lifetime without wear leveling. |
| Data Retention | 20 years at 125°C - ensures long-term reliability in automotive engine control units and industrial PLCs. |
| VIO Range | 1.65–3.6 V - allows interoperability with 1.8 V or 3.3 V logic domains without level shifters. |
| Page Read Buffer | 8-word (16-byte) - reduces sequential read latency during code fetch or configuration table access. |
| Write Buffer Size | 16-word (32-byte) - accelerates multi-word programming in bootloader update routines. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 (DQ15/A-1) enables 16-bit mode with MSB aliasing. |
| DQ0–DQ15 | Data/Address Multiplexed I/O | 16-bit bidirectional data bus; DQ15 doubles as A-1 in word mode for extended addressing. |
| CE#, WE#, OE# | Chip/Write/Output Enable Controls | Independent active-low enables allow precise timing control for burst reads and page writes without bus contention. |
| RESET# | Hardware Reset Input | Asynchronous reset terminates ongoing program/erase and restores device to read mode - critical for safe boot recovery. |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating internal operation progress - eliminates need for polling in interrupt-driven firmware. |
| WP#/ACC | Write Protect / Accelerated Program Input | Low-active write protect for top/bottom sector; high-voltage mode (ACC) cuts programming time by ~30% in production test. |
| BYTE# | Bus Width Select | Configures 16-bit (high) or 8-bit (low) data interface - enables compatibility with legacy 8-bit microcontrollers. |
| VIO | I/O Voltage Reference | Defines input threshold and output drive strength independently of VCC - decouples core logic from system I/O voltage domain. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory-locked region with 16-byte electronic serial number - enables secure device authentication and anti-cloning in certified industrial modules. |
| Program/Erase Suspend | Allows interruption of active programming or erasing to service higher-priority reads - essential for real-time OS coexistence with firmware updates. |
| CFI Compliance | Standardized parameter table accessible via command sequence - permits automatic flash detection and driver initialization in Linux U-Boot and bare-metal BSPs. |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles - improves throughput in manufacturing flash programming stations. |
| Persistent Sector Protection | Non-volatile PPB lock bit prevents accidental sector unlock - eliminates risk of corruption during power-loss events in unattended remote equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same density and 90 ns speed, but uses 64-ball Fortified BGA (LAA064) instead of 48-pin TSOP; no BYTE# pin. | Targeted for space-constrained telecom modules where board area > pin count flexibility. | Select when footprint reduction and thermal performance outweigh need for 8-bit bus compatibility. |
| MX29GL640EHT2I-90G | 64 Mbit, 90 ns, 3 V, but lacks Secured Silicon Sector and Password Sector Protection; uses different command set. | Suitable for cost-sensitive consumer devices where security features are not required. | Choose only if CFI compliance and basic sector erase suffice - avoid where firmware authenticity or regulatory traceability is mandated. |
Compared with S29GL064S90TFI020, the S29GL064N90TFI040 offers superior design flexibility via BYTE# and TSOP ease-of-handling, while MX29GL640EHT2I-90G trades security and command compatibility for lower unit cost - making the original part optimal for regulated, updatable, and I/O-flexible embedded systems.

FAQ
What is the function of the WP#/ACC pin on S29GL064N90TFI040?
The WP#/ACC pin serves dual functions: when pulled low, it write-protects the top or bottom sector regardless of software protection settings; when driven to VCC + 0.5 V (typically 3.6–4.2 V), it activates accelerated programming mode, reducing typical word-program time by approximately 30%. This dual-role pin is electrically isolated from VCC and requires external voltage boosting circuitry for ACC operation.
Does S29GL064N90TFI040 support 8-bit data bus operation?
Yes, the device supports 8-bit operation via the BYTE# pin: when BYTE# is low, DQ0–DQ7 function as an 8-bit data bus with DQ15–DQ8 disabled; when high, it operates as a full 16-bit bus. This mode is fully compatible with JEDEC-standard 8-bit microcontrollers and eliminates need for external data bus multiplexing logic.
How is the Secured Silicon Sector accessed and protected?
The Secured Silicon Sector is a 256-byte region (128 words) pre-programmed with a unique 16-byte electronic serial number at factory. Access requires issuing the dedicated Enter Secured Silicon Sector command (0x00, 0x00, 0x00, 0x00, 0x00, 0x00); once locked via command 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, no further writes or erases are possible - even with VPP applied - ensuring permanent identity binding.
Can S29GL064N90TFI040 be used in systems with mixed 1.8 V and 3.3 V I/O domains?
Yes, the VIO pin accepts 1.65–3.6 V, allowing independent configuration of I/O voltage levels. With VIO = 1.8 V, inputs recognize 1.8 V logic thresholds and outputs drive 1.8 V-compatible loads, while VCC remains at 3.0 V for core flash operation - enabling direct interfacing with 1.8 V FPGAs or ASICs without level shifters.
