Product details
Overview
S29GL256N11FAI010 from Cypress Semiconductor is a 256 Mbit (33,554,432-byte), 16-bit parallel NOR Flash memory using 110 nm MirrorBit technology, operating from a single 3.0 V supply with 110 ns access time and 25 ns page read time. It features flexible sector architecture (256 × 128 KB sectors), Secured Silicon Sector with 128-word electronic serial number, and JEDEC-compliant command set for embedded boot code storage in industrial control systems.
For engineers reviewing the S29GL256N11FAI010 datasheet, S29GL256N11FAI010 pinout, S29GL256N11FAI010 application, or S29GL256N11FAI010 equivalent, key selection criteria include 3.0 V single-supply operation, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, sector erase suspend/resume capability, and CFI compliance for host system auto-configuration.
Technical Context
This device implements a parallel asynchronous interface with separate CE#, OE#, and WE# controls, supporting both word (16-bit) and byte (8-bit via BYTE#) configurations. Its architecture includes on-chip voltage generators for erase/program, a state machine-driven command execution engine, and dual status reporting via DQ7 polling and RY/BY# output.
The Enhanced VersatileI/O™ (VIO) input sets I/O voltage levels (1.65–3.6 V), enabling interoperability with 1.8 V or 3 V host buses. Sector protection is implemented through persistent lock bits, password-protected regions, and hardware WP#/ACC acceleration-enabling secure, high-throughput factory programming without external HV sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (16,777,216 words × 16-bit) |
| Access Time | 110 ns max at VCC = 2.7–3.6 V, VIO = 2.7–3.6 V - defines minimum bus cycle timing for reliable read operations |
| Page Read Time | 25 ns - enables burst reads of up to 8 words from internal buffer, reducing sequential access latency |
| Erase Endurance | 100,000 cycles per sector - supports field firmware updates over extended product lifetimes |
| Data Retention | 20 years typical - ensures long-term integrity of boot code and calibration data without refresh |
| Supply Voltage | Single 3.0 V (2.7–3.6 V) for read, program, and erase - eliminates need for auxiliary voltage rails |
| Standby Current | 1 µA typical - minimizes power draw during system sleep modes in battery-backed applications |
Pinout & Package
Package: 56-pin TSOP (Thin Small Outline Package), standard industrial footprint compatible with automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A23 | Address Inputs | 24-bit address bus supporting full 256 Mbit addressing (A23 valid); A22 is MSB for this density |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; BYTE# selects 8-bit mode (DQ0–DQ7 only) |
| CE# | Chip Enable | Active-low chip select; device enters standby when deasserted during read/write |
| OE# | Output Enable | Active-low control for data bus drivers; enables read data output without affecting internal state |
| WE# | Write Enable | Active-low strobe for latching addresses/data during command sequences and programming |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing erase/program and returns device to read mode |
| RY/BY# | Ready/Busy Output | Open-drain status signal: low = operation in progress, high = ready for next command |
| VIO | I/O Voltage Reference | Sets input threshold and output drive level (1.65–3.6 V); decouples I/O logic from core VCC |
| WP#/ACC | Write Protect / Acceleration | Low = hardware sector protection (first/last sector); high + VCC = accelerated program timing |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with unique 8-word electronic serial number for secure device identification |
| Program/Erase Suspend | Allows interruption of active program/erase in one sector to perform read/program in another - critical for real-time firmware update scenarios |
| CFI Compliance | Enables automatic detection of device geometry, timing, and command set by host BIOS/bootloader without hard-coded parameters |
| Password Sector Protection | 64-bit user-defined password required to unlock protected sectors - prevents unauthorized firmware modification in deployed systems |
| Enhanced VersatileI/O™ | VIO pin configures all I/O thresholds and drive strength to match host bus voltage (1.65–3.6 V), eliminating level shifters |

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 |
|---|---|---|---|
| S29GL256S11TFI010 | Successor part with 65 nm process; 90 ns access time, lower active current (20 mA), same 56-pin TSOP package | Requires updated timing margins in legacy designs; supports higher throughput in new controllers | Select for new designs requiring improved speed/power; verify RESET# timing compatibility with host MCU |
| MX29GL256FHTI-90G | Micron pin-compatible replacement; identical 110 ns access, same sector map, but no Secured Silicon Sector or password protection | Lacks electronic serial number and password-based sector locking - unsuitable for security-sensitive deployments | Use where cost optimization is primary and security features are not required; validate CFI descriptor table alignment |
Compared with S29GL256N11FAI010, the S29GL256S11TFI010 delivers faster access and lower power at the cost of revised reset timing, while the MX29GL256FHTI-90G matches timing but omits silicon-level security - making the original optimal for legacy systems needing certified secure boot storage.

FAQ
Is S29GL256N11FAI010 still in production?
No - Cypress officially retired the S29GL-N family in 2016 and recommends migration to the S29GL-S (65 nm) or S29GL-T (45 nm) families. However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle support including last-time buy planning and cross-reference assistance for qualified replacements.
What is the function of the WP#/ACC pin?
The WP#/ACC pin serves two roles: when pulled low, it hardware-protects the first or last memory sector; when driven high with VCC applied, it enables accelerated programming by increasing internal pump current - reducing write time by ~30% during factory programming without altering command sequences.
Can S29GL256N11FAI010 operate with a 1.8 V I/O interface?
Yes - the VIO pin accepts 1.65–3.6 V, allowing full 16-bit I/O operation at 1.8 V logic levels when VIO = 1.8 V. Address, control, and data pins automatically adapt thresholds and drive strength; VCC remains at 3.0 V for core memory operation, maintaining full 110 ns access performance.
Does this device support byte-write operations?
No - the S29GL256N11FAI010 is a 16-bit-wide device. Byte writes are emulated via BYTE# pin assertion, which restricts data bus access to DQ0–DQ7 and maps them to the lower byte of each 16-bit word; true independent 8-bit writes are not supported - all programming occurs in 16-bit units.
