Product details
Overview
S29GL032N90FFI023 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit-wide single-supply MirrorBit Flash memory organized as 2,097,152 words (4,194,304 bytes), featuring 90 ns access time, 25 ns page read time, and uniform sector architecture with sixty-four 32 Kword (64 KB) sectors. It operates from a single 3.0 V supply (2.7–3.6 V), supports JEDEC-compliant command set, and is used for boot code storage and firmware updates in industrial control systems.
For engineers reviewing the S29GL032N90FFI023 datasheet, S29GL032N90FFI023 pinout, S29GL032N90FFI023 application, or S29GL032N90FFI023 equivalent, key selection criteria include uniform sector erase capability, Secured Silicon Sector with factory-programmed 128-word ESN, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), and hardware reset (RESET#) with RY/BY# status signaling.
Technical Context
This device implements hot-electron injection programming and hot-hole assisted sector erase within a 110 nm MirrorBit process. Its architecture includes separate CE#, WE#, and OE# controls, enabling true concurrent read-while-write via Program Suspend/Resume and Erase Suspend/Resume features.
The Secured Silicon Sector provides 256-byte factory-locked or customer-lockable space with 8-word electronic serial number; Advanced Sector Protection supports both Persistent and Password-based locking modes, with CFI compliance enabling automatic host system identification and configuration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI020 | Same die, 48-ball fine-pitch BGA (VBK048) package instead of 48-pin TSOP; no WP#/ACC pin - uses dedicated WP# only | Preferred for space-constrained PCBs where board area is prioritized over manual rework accessibility | Select when using automated BGA assembly and requiring smaller footprint; verify thermal pad grounding per VBK048 mechanical spec |
| MX29GL32EHXFI-90G | Macleod 32 Mbit Flash; 90 ns access but lacks Secured Silicon Sector and Password Sector Protection; different command set | Suitable for cost-sensitive consumer applications where security features are not required | Choose only if CFI compatibility and advanced protection are unnecessary; requires full firmware driver rewrite due to non-JEDEC command differences |
Compared with S29GL032N90FFI023, the TSOP-packaged alternative offers identical functionality and full pin/command compatibility, while the Macronix part sacrifices security and suspend features for lower unit cost - making it viable only in non-certified, non-updatable deployments.

FAQ
Does S29GL032N90FFI023 support byte-wide data access?
Yes - when BYTE# is asserted LOW, the device operates in 8-bit mode using DQ0–DQ7 only, with DQ15 functioning as A-1 to select upper/lower byte addressing. This enables compatibility with 8-bit microcontrollers and legacy bus architectures without external data multiplexing.
What is the function of the WP#/ACC pin in normal operation?
In normal operation, WP#/ACC serves dual roles: pulled LOW to protect the first or last sector from accidental writes/erases, or driven HIGH with VHH (12 V) to accelerate programming throughput during manufacturing. No external high-voltage source is needed for standard operation - VHH is only required for ACC mode.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 256-byte region (128 words) that can be permanently locked after factory or customer programming. Once secured, no further writes or erases are possible - even with valid unlock commands - ensuring immutable device identity or calibration data remains tamper-proof.
Is S29GL032N90FFI023 compatible with legacy S29GL032P designs?
No - S29GL032N uses the newer 110 nm MirrorBit process and revised command set versus the older S29GL032P (90 nm). Key incompatibilities include absence of VPP pin, different RESET# behavior, and updated CFI query structure; migration requires firmware and timing validation per Infineon AN98525 Rev. *B.
