Product details
Overview
S29GL256N11FFI023 from Cypress Semiconductor is a 256 Mbit (33,554,432-byte), 16-bit wide, single-supply 3.0 V page flash memory fabricated on 110 nm MirrorBit technology, featuring 90 ns access time, 25 ns page read time, and 100,000 erase cycles per sector - deployed in embedded boot code storage, firmware update partitions, and industrial control configuration memory.
For engineers reviewing the S29GL256N11FFI023 datasheet, S29GL256N11FFI023 pinout, S29GL256N11FFI023 application, or S29GL256N11FFI023 equivalent, key selection criteria include JEDEC-compliant command set compatibility, VIO-adjustable I/O voltage (1.65–3.6 V), Secured Silicon Sector with 128-word serial ID, and hardware reset (RESET#) support for system boot integrity.
Technical Context
This device implements a sector-erase architecture with 256 independent 128 Kbyte sectors, enabling selective reprogramming without disturbing adjacent data. It supports both byte- and word-mode operations via BYTE# control and uses hot-electron injection for programming and hot-hole assisted erase.
Its Enhanced VersatileI/O™ interface decouples VIO from VCC, allowing simultaneous operation in mixed-voltage systems (e.g., 3.3 V core / 1.8 V I/O). Status monitoring relies on DQ7 polling, DQ6 toggle bits, and RY/BY# output - all compliant with Common Flash Interface (CFI) standards for host auto-detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (16,777,216 words × 16-bit), organized as 256 × 128 Kbyte sectors - enables full firmware image storage with sector-level update granularity. |
| Access Time | 90 ns (VCC = 3.0–3.6 V, VIO = 3.0–3.6 V) - meets real-time boot latency requirements for industrial microcontrollers. |
| Page Read Time | 25 ns - accelerates sequential instruction fetch during execution-in-place (XIP) scenarios. |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over 10+ years in deployed equipment. |
| Data Retention | 20 years at 125 °C - ensures long-term reliability in automotive under-hood and industrial high-temp environments. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V - allows interoperability with 1.8 V logic buses while maintaining 3 V core operation. |
| Standby Current | 1 µA typical - reduces quiescent power in battery-backed or always-on edge nodes. |
Pinout & Package
Package: 56-pin TSOP (Thin Small Outline Package), standard footprint compatible with legacy PCB layouts and automated assembly processes.
| 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/IO Bidirectional Bus | 16-bit parallel interface; BYTE# selects 8-bit mode for legacy 8-bit microcontroller compatibility. |
| CE#, OE#, WE# | Chip/Output/Write Enable Controls | Independent gating enables precise timing control for multi-device memory maps and burst reads. |
| RESET# | Hardware Reset Input | Asynchronous active-low signal that aborts ongoing erase/program and restores ready state - critical for safe boot recovery. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator tied to system interrupt or polling loop to synchronize host software with flash operations. |
| VIO | I/O Voltage Reference | Configures input thresholds and output drive levels across entire pin set - eliminates level-shifter components in mixed-voltage designs. |
| WP#/ACC | Write Protect / Accelerated Program | Low-active write protection for top/bottom sector; high-voltage mode shortens program time during factory programming. |
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 identification and immutable boot loader storage. |
| Program/Erase Suspend | Allows pausing active program/erase to service higher-priority reads from other sectors - essential for real-time OS firmware updates without blocking application threads. |
| Password Sector Protection | 64-bit user-defined password prevents unauthorized sector erase/write - satisfies IEC 62443-3-3 requirement for authenticated firmware modification. |
| CFI Compliance | Standardized query table at address 0x0055 allows runtime detection of geometry, timing, and command set - simplifies BSP development across multiple flash vendors. |
| Persistent Sector Protection | Non-volatile lock bits retain protection state across power cycles - eliminates need for boot-time reconfiguration of protected sectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S11FFI020 | Successor part using 90 nm process; 100 ns access time; supports deeper sleep modes and enhanced CFI revision. | Designed for new designs requiring extended lifecycle support and lower active current (22 mA vs. 25 mA). | Select when designing new platforms with ≥5-year production horizon and need Cypress's current-generation support. |
| MX29GL256FHI-90G | Macronix pin-compatible alternative; same 90 ns access, 256 Mbit density, TSOP-56 package; lacks Secured Silicon Sector and password protection. | Used where cost sensitivity outweighs security features; requires external authentication for firmware integrity. | Choose for cost-optimized industrial controls where cryptographic verification is handled externally. |
Compared with S29GL256N11FFI023, the S29GL256S11FFI020 offers longer manufacturer support and improved power efficiency but requires minor timing adjustments, while the MX29GL256FHI-90G delivers identical performance at lower cost but omits hardware-based security features essential for regulated applications.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in memory, microcontrollers, and connectivity solutions for industrial, automotive, and consumer markets.
The S29GL-N family was designed for high-reliability embedded systems requiring JEDEC-standard flash with hardware security, mixed-voltage I/O flexibility, and long-term data retention - targeting mission-critical firmware storage where field upgradeability and tamper resistance are mandatory.
FAQ
Is S29GL256N11FFI023 still in production?
No - Cypress officially retired the S29GL-N family in 2016 and recommends migration to the S29GL-S series (e.g., S29GL256S). However, Aetrix Electronics maintains limited legacy inventory with full traceability and supports existing designs through last-time-buy programs and controlled distribution channels.
What is the function of the WP#/ACC pin?
The WP#/ACC pin serves dual roles: when pulled low, it protects the top or bottom sector from accidental writes; when driven to 5.5 V (via external charge pump), it enables accelerated programming for faster factory throughput. Its voltage-tolerant design allows safe use in 3 V systems with optional HV boost circuitry.
Can S29GL256N11FFI023 operate with 1.8 V I/O while VCC is at 3.3 V?
Yes - the Enhanced VersatileI/O™ architecture lets VIO be set independently from VCC. With VIO = 1.8 V and VCC = 3.3 V, all inputs (address, control, DQ) recognize 1.8 V logic thresholds and outputs drive to 1.8 V levels, eliminating external level shifters in mixed-voltage SoC interfaces.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region with permanent lock capability: once locked, no further writes or erases are possible, even with valid commands. It contains a factory-programmed 8-word electronic serial number and supports customer-defined data - used for device binding, license enforcement, and anti-cloning in certified equipment.
