Product details
Overview
S29GL032N90FAI033 from Infineon Technologies (formerly Cypress) is a 32-Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed 16-byte electronic serial number. It operates from 2.7–3.6 V VCC and 1.65–3.6 V VIO, supporting boot code storage in industrial controllers and firmware retention in network edge devices.
For engineers reviewing the S29GL032N90FAI033 datasheet, S29GL032N90FAI033 pinout, S29GL032N90FAI033 application, or S29GL032N90FAI033 equivalent, key selection criteria include JEDEC-compliant command set, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, 100,000 erase cycles per sector, CFI compliance for host auto-configuration, and WP#/ACC-accelerated programming for production throughput.
Technical Context
This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase. Its sector-based erase model supports independent erasure of 64 uniform 64 KB sectors without affecting adjacent data, enabling robust firmware update partitioning.
The VersatileI/O™ control uses VIO to define all input thresholds and output drive levels, allowing interoperability with mixed-voltage systems. Command execution relies on internal latching of addresses/data during write cycles, eliminating external address/data bus hold timing constraints.
Key Specifications

| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page read time - reduces sequential instruction fetch latency |
| Write Buffer | 16-word (32-byte) buffer - cuts multi-word programming time by >50% vs. single-word writes |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 32 Mbit addressing; A-1 used as DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; DQ15 doubles as A-1 for x16 configuration |
| CE# | Chip enable (active low) | Enables device for read/write; must be asserted before OE# or WE# for valid operation |
| OE# | Output enable (active low) | Gates output drivers; used for read operations only |
| WE# | Write enable (active low) | Controls write/erase command latching and data programming timing |
| WP#/ACC | Write protect / accelerated program input | Low = protects first/last sector; high voltage = accelerates programming for production test |
| RESET# | Hardware reset (active low) | Aborts ongoing erase/program and returns device to read mode; tied to system reset |
| RY/BY# | Ready/Busy output (active low) | Indicates active programming/erase; used for hardware polling instead of software status reads |
| BYTE# | Bus width select | High = x16 mode; low = x8 mode (DQ0–DQ7 only active); enables flexible memory mapping |
| VIO | I/O supply voltage | Sets input thresholds and output drive strength independently from VCC |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word (16-byte) electronic serial number - provides immutable device identity for secure boot and anti-counterfeiting |
| Program/Erase Suspend & Resume | Allows interruption of active programming or erase to service higher-priority reads from other sectors - essential for real-time OS firmware updates |
| CFI Compliance | Standardized query table at fixed address enables automatic detection and parameter loading by host BIOS/bootloader - eliminates hard-coded flash timing tables |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word - increases production programming throughput by ~33% |
| Persistent Sector Protection | Non-volatile lock bits disable program/erase permanently until cleared via dedicated unlock sequence - prevents accidental corruption of critical boot sectors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI020 | Same die, 48-ball fine-pitch BGA (VBK048) package; no WP#/ACC pin - lacks hardware-accelerated programming | Used where board space is constrained and production programming occurs off-line, not in-system | Select when footprint reduction outweighs need for in-field accelerated programming |
| MX29GL32EHXFI-90G | Micron 32 Mbit NOR Flash; 90 ns access, but uses different command set (non-CFI compliant) and lacks Secured Silicon Sector | Deployed in cost-sensitive consumer gateways where secure identity is not required | Select only if host firmware can be modified to support Micron-specific commands and security is handled externally |
Compared with S29GL032N90FAI033, the BGA variant sacrifices WP#/ACC functionality for compactness, while the Micron alternative trades CFI compatibility and secure silicon for lower unit cost - neither offers identical combination of hardware reset, RY/BY# signaling, and factory-locked identity.

FAQ
What is the function of the WP#/ACC pin on S29GL032N90FAI033?
The WP#/ACC pin serves dual roles: when held low, it protects the first or last sector from accidental program/erase; when driven to VCC + 2.5 V (up to 4.5 V), it enables accelerated programming for faster production testing. This voltage-level switching is internally detected and does not require external circuitry beyond a simple voltage translator during manufacturing.
Does S29GL032N90FAI033 support both x8 and x16 data bus widths?
Yes - the BYTE# pin selects bus width: high enables full 16-bit operation (DQ0–DQ15 active), while low configures x8 mode (DQ0–DQ7 only). In x8 mode, DQ15 functions as A-1 for extended addressing. This flexibility allows use in legacy 8-bit microcontrollers or modern 16-bit SoCs without redesigning the memory interface.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector is pre-programmed with a unique 16-byte electronic serial number at the factory and permanently locked using fuse-based protection. Once locked, no command sequence can modify its contents. Customers may also program and lock custom data into this region using the Enter/Exit Secured Silicon Sector command sequence, followed by a permanent lock command that disables further writes.
Can S29GL032N90FAI033 be used in systems with 1.8 V I/O interfaces?
Yes - the VIO pin accepts 1.65–3.6 V, so applying 1.8 V to VIO configures all inputs to recognize 1.8 V logic thresholds and drives outputs to 1.8 V levels. VCC remains at 3.0 V (2.7–3.6 V range) for core memory operation. This dual-supply decoupling enables seamless integration with 1.8 V FPGAs or ASICs while maintaining full flash performance.
