Product details
Overview
S29GL256N90TFIR10 from Cypress Semiconductor is a 256 Mbit (33,554,432-byte), 3.0 V single-power-supply NOR Flash memory using 110 nm MirrorBit technology, organized in 256 × 128 Kbyte sectors, with 90 ns access time, 25 ns page read time, and 1 µA standby current. It serves as non-volatile program/data storage in boot code execution, firmware update, and embedded control systems.
For engineers reviewing the S29GL256N90TFIR10 datasheet, S29GL256N90TFIR10 pinout, S29GL256N90TFIR10 application, or S29GL256N90TFIR10 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with 128-word ESN, Enhanced VersatileI/O™ (VIO = 1.65–3.6 V), and hardware reset (RESET#) for system-level boot reliability.
Technical Context
This device implements a sector-erase NOR Flash architecture with separate CE#, WE#, and OE# controls, enabling concurrent read/program/erase operations via Program Suspend and Erase Suspend features. It supports both 8-bit and 16-bit data bus modes via BYTE# input and uses hot-electron injection for programming and hot-hole assisted erase.
The CFI-compliant interface allows automatic device identification by host systems, while Persistent Sector Protection and Password Sector Protection provide in-system, command-enabled write/erase security without external components. VIO voltage scaling enables interoperability across 1.8 V and 3.0 V host environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (33,554,432 bytes), organized as 256 × 128 Kbyte sectors - defines firmware image capacity and partitioning granularity. |
| Access Time | 90 ns at VCC = 3.0–3.6 V, VIO = 3.0–3.6 V - ensures fast boot code fetch timing in real-time embedded systems. |
| Page Read Time | 25 ns - reduces latency during sequential instruction fetch from buffered 8-word/16-byte read buffer. |
| Standby Current | 1 µA typical - enables ultra-low power retention in battery-backed or energy-constrained applications. |
| Erase Cycles | 100,000 per sector typical - supports field firmware updates over extended product lifetime. |
| Data Retention | 20 years typical - guarantees long-term integrity of stored boot code and calibration data. |
| VIO Range | 1.65 V to VCC - allows direct interfacing with mixed-voltage SoCs without level shifters. |
Pinout & Package
Package: 56-pin TSOP (Thin Small Outline Package), standard industrial footprint compatible with legacy PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A23 | Address Inputs | 24-bit address bus supporting full 256 Mbit addressing; A23 is MSB for this density. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; BYTE# selects 8-bit mode for narrower bus interfaces. |
| CE# | Chip Enable | Active-low chip select; enables device for read/write when asserted with valid address. |
| OE# | Output Enable | Active-low output gate; controls data bus drivers during read cycles only. |
| WE# | Write Enable | Active-low write strobe; latches addresses/data during command and programming sequences. |
| WP#/ACC | Write Protect / Accelerated Program | Low = sector protection; high + VCC = accelerated programming for production throughput. |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing operations and restores device to ready state. |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active erase/program cycle completion. |
| VIO | I/O Voltage Reference | Sets logic thresholds for all address/control/data pins - enables 1.8 V or 3.0 V system compatibility. |
| BYTE# | Bus Width Select | High = 16-bit mode; low = 8-bit mode (DQ0–DQ7 only active). |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word electronic serial number - enables secure device identity and immutable boot code storage. |
| Enhanced VersatileI/O™ | VIO pin sets all input/output voltage thresholds (1.65–3.6 V) - eliminates need for external level shifters in mixed-voltage designs. |
| Program/Erase Suspend | Pause active programming or erasing to read/program other sectors - enables real-time firmware updates without halting system operation. |
| CFI Compliance | Standardized JEDEC query table accessible via command sequence - allows automatic flash detection and configuration in generic bootloader software. |
| Password Sector Protection | 64-bit user-defined password required to unlock protected sectors - prevents unauthorized firmware modification in deployed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S90TFIR20 | Successor device; same density and 90 ns speed, but built on 90 nm process with improved ECC support and extended temperature range (–40°C to +105°C). | Supports automotive AEC-Q100 Grade 2 qualification; includes enhanced CFI revision for newer bootloader compatibility. | Select for new designs requiring longer lifecycle support, higher reliability, or extended thermal operation. |
| MX29GL256FHT2I-90G | Macronix pin-compatible alternative; identical 256 Mbit/90 ns TSOP package, but lacks Secured Silicon Sector and uses different command set for password protection. | Lower cost option where secure serial number and factory-lockable sector are not required. | Select when budget constraints outweigh need for cryptographic identity or permanent secure storage. |
Compared with S29GL256N90TFIR10, the S29GL256S90TFIR20 offers longer manufacturer support and broader environmental specs, while MX29GL256FHT2I-90G provides cost-effective drop-in replacement where security features are secondary.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in microcontrollers, connectivity solutions, and non-volatile memory, headquartered in San Jose, California.

FAQ
Is S29GL256N90TFIR10 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and has been superseded by the S29GL256S series. While functional and available through legacy channels, new projects should use S29GL256S90TFIR20 for guaranteed long-term supply, updated qualification, and enhanced features like improved ECC and extended temperature range.
What is the role of the WP#/ACC pin in normal operation versus production programming?
In normal operation, pulling WP#/ACC low protects the first or last sector from accidental writes. During production programming, applying VCC to WP#/ACC enables accelerated programming mode, reducing individual word programming time by ~30% and improving throughput on automated flash programmers - a feature intended for factory use but usable in-field if needed.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at the factory or by the user. Once locked, no further writes or erases are possible-even with valid commands or passwords. It contains an 8-word electronic serial number and is used for immutable device identity, secure boot keys, or calibration constants that must survive all future firmware updates.
Can S29GL256N90TFIR10 operate in a 1.8 V I/O system?
Yes, via the VIO pin. When VIO is supplied at 1.8 V (within 1.65–3.6 V range), all address, control, and data pins conform to 1.8 V logic thresholds-enabling direct connection to 1.8 V SoCs or FPGAs without level shifters. VCC remains at 3.0–3.6 V for core memory operation, maintaining full performance and reliability.
