Product details
Overview
S29GL032N90FAI040 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-power-supply MirrorBit Flash memory IC with 90 ns access time, organized as 2,097,152 words (4,194,304 bytes), featuring uniform sector architecture (64 × 64 KB sectors), Secured Silicon Sector, and CFI compliance. It operates from a single 3.0 V supply (2.7–3.6 V), supports page read/write buffers, and is used in embedded boot code storage for industrial controllers and network edge devices.
For engineers reviewing the S29GL032N90FAI040 datasheet, S29GL032N90FAI040 pinout, S29GL032N90FAI040 application, or S29GL032N90FAI040 equivalent, key selection criteria include JEDEC software compatibility, 100,000 erase cycles per sector, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, VIO-controlled I/O flexibility (1.65–3.6 V), and factory-programmed 128-word Electronic Serial Number in the Secured Silicon Sector.
Technical Context
This device implements a command-set-compatible NOR Flash architecture with hot-electron programming and hot-hole assisted erase. Its sector erase model enables selective reprogramming without disturbing adjacent sectors, and its Advanced Sector Protection includes both Persistent and Password-based locking mechanisms for firmware integrity.
The VersatileI/O™ control uses VIO to set input thresholds and output drive levels independently of VCC, enabling interoperability with mixed-voltage systems. The CFI interface allows automatic device identification and parameter retrieval by host firmware during initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16-bit words); sufficient for full boot loader + configuration data in resource-constrained embedded systems. |
| Access Time | 90 ns at VCC = 2.7–3.6 V; ensures deterministic timing for real-time firmware fetch in microcontroller-based applications. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over product lifetime in industrial gateways and PLCs. |
| Data Retention | 20 years typical; guarantees long-term reliability of stored calibration data and security keys without refresh. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct interfacing with 1.8 V or 3.3 V logic while maintaining full read/write functionality. |
| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page access; reduces sequential instruction fetch latency in XIP (execute-in-place) configurations. |
| Write Buffer | 16-word (32-byte) buffer; cuts multi-word programming time by minimizing command overhead per write burst. |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), lead pitch 0.5 mm, body size 12 × 20 mm - suitable for high-density PCB layouts in space-constrained industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) multiplexes most significant data bit and address bit for 16-bit mode. |
| DQ0–DQ15 | Data/Address Multiplexed I/O | 16-bit bidirectional data bus; DQ15 doubles as A-1 in word mode, enabling compact address decoding. |
| CE#, OE#, WE# | Chip/Output/Write Enable Controls | Independent active-low enables allow precise timing control and support for interleaved read/write operations in multi-chip systems. |
| RESET# | Hardware Reset Input | Asynchronous reset terminates ongoing erase/program cycles and returns device to read mode; ties directly to system reset rail. |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicates active programming/erase; enables polling-free interrupt-driven firmware flow control. |
| WP#/ACC | Write Protect / Accelerated Program Input | Low assertion protects first/last sector; high-voltage application (VCC + 1.5 V) enables accelerated programming for production throughput. |
| BYTE# | Bus Width Select | Configures 16-bit or 8-bit data interface; critical for compatibility with legacy 8-bit microcontrollers or FPGA soft cores. |
| VIO | I/O Voltage Reference | Sets input threshold and output drive level independently of VCC; enables seamless integration with mixed-voltage SoC interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word ESN; provides tamper-resistant storage for cryptographic keys or device identity. |
| Program/Erase Suspend | Allows interruption of active program/erase to service higher-priority reads elsewhere; essential for real-time OS environments with concurrent flash access. |
| CFI Compliance | Enables automatic detection of device geometry, timing, and protection features via standardized query commands; eliminates hard-coded flash parameters in bootloader. |
| Unlock Bypass Mode | Reduces multi-word programming from four to two write cycles per word; improves firmware update speed by ~50% in host-controlled field upgrades. |
| Hardware Data Protection | Low-VCC detector disables writes during power ramp-up/down; prevents corruption during brown-out or cold-start conditions in unregulated power systems. |
Applications
| Industrial PLC Firmware Storage | Network Router Boot Memory |
|---|---|
|
Use Scenario: Storing boot code and runtime firmware for programmable logic controllers operating in harsh temperature and EMI environments. IC Role / Device Role / Timing Role: Non-volatile boot memory mapped into MCU address space; executes XIP during cold start with deterministic 90 ns access. Use Value: Uniform 64 KB sectors enable atomic firmware updates; 20-year data retention ensures calibration data survives extended deployment without backup power. |
Use Scenario: Holding bootloader, kernel image, and configuration tables in enterprise-grade Ethernet routers requiring secure, field-upgradable storage. IC Role / Device Role / Timing Role: Primary boot device accessed via parallel bus during power-on reset; supports CFI auto-configuration and password-protected sector lockdown. Use Value: Secured Silicon Sector stores device-specific keys for TLS handshake; Persistent Sector Protection prevents accidental overwrite of critical boot vectors. |
| Medical Diagnostic Equipment BIOS | Automotive Body Control Module |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI030 | Same die, 48-ball fine-pitch BGA (VBK048) package instead of 48-pin TSOP; identical timing and command set. | Used where board area is constrained and automated BGA reflow is available; no change to firmware or timing margins. | Select for space-optimized designs with compatible assembly capability; requires updated footprint and stencil design. |
| MX29GL320EBTI-90G | 32 Mbit, 90 ns, but uses standard JEDEC command set without CFI query support; lacks Secured Silicon Sector and password protection. | Suitable for cost-sensitive consumer electronics where firmware security and field upgrade robustness are secondary. | Choose only when CFI auto-detection, electronic serial number, or persistent sector lock are not required. |
Compared with S29GL032N90FAI040, the TSOP-packaged alternative offers identical functionality in a through-hole-compatible form factor, while the Macronix part trades security and configurability for lower unit cost-making it viable only in non-security-critical, high-volume applications.

FAQ
Is S29GL032N90FAI040 pin-compatible with earlier S29GL032N variants using TSOP packages?
Yes - all S29GL032N 48-pin TSOP variants (including models ending in 'AI040', 'AI020', and 'TI020') share identical pinout, electrical characteristics, and command set. The suffix denotes speed grade and temperature range, not physical or functional divergence.
Does this device support true 8-bit data bus operation?
Yes - asserting BYTE# low configures DQ0–DQ7 as an 8-bit data bus while disabling DQ8–DQ15; A0–A20 remain fully functional, and all commands operate identically, enabling drop-in replacement for legacy 8-bit microcontrollers.
What happens to the Secured Silicon Sector after factory programming?
Once locked via the Secured Silicon Sector Lock command, the 128-word region becomes permanently read-only; no subsequent command, voltage, or timing sequence can unlock or rewrite it - ensuring cryptographic keys or serial numbers remain immutable throughout device life.
Can RESET# be used to abort an ongoing erase operation safely?
Yes - asserting RESET# asynchronously terminates any active erase or program cycle, resets internal state machines, and returns the device to read mode within 100 ns; all sectors retain their pre-interrupt data state, and no corruption occurs.
