Product details
Overview
S29GL032N90BFI040 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 electronic serial number. It operates from 2.7–3.6 V VCC and 1.65–3.6 V VIO, and is used in industrial control firmware storage where deterministic boot code integrity and long-term data retention are required.
For engineers reviewing the S29GL032N90BFI040 datasheet, S29GL032N90BFI040 pinout, S29GL032N90BFI040 application, or S29GL032N90BFI040 equivalent, key selection criteria include JEDEC-compliant command set, hardware write protection via WP#/ACC, CFI compliance for host auto-configuration, and 100,000 erase cycles per sector with 20-year data retention.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It supports both uniform and boot-sector configurations, though S29GL032N90BFI040 is specifically a uniform-sector model with 64 identical 64 KB sectors.
It features VersatileI/O™ control: all input thresholds and output drive levels scale with VIO (1.65–3.6 V), enabling interoperability with mixed-voltage systems. Command execution uses standard microprocessor write timing, with status reported via DQ7 polling, DQ6 toggle bits, or RY/BY# signal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 32 Mbit (4,194,304 bytes), organized as 2,097,152 × 16-bit words |
| Access time | 90 ns max at VCC = 2.7–3.6 V - guarantees deterministic read latency for real-time boot code fetch |
| Sector architecture | 64 uniform 64 KB sectors - enables granular firmware updates without disturbing adjacent code regions |
| Erase endurance | 100,000 cycles typical per sector - supports field firmware upgrades over product lifetime |
| Data retention | 20 years typical at 125°C - validated for extended operation in industrial temperature environments |
| Supply voltage | VCC = 2.7–3.6 V; VIO = 1.65–3.6 V - allows direct interface to 1.8 V, 2.5 V, or 3.3 V logic without level shifters |
| Page buffer | 8-word (16-byte) read buffer and 16-word (32-byte) write buffer - reduces sequential multi-word programming overhead |
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 4 MB addressing space; A-1 (DQ15/A-1) multiplexed for byte/word mode selection |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel data path; DQ15 doubles as A-1 for BYTE#-controlled 8-bit mode |
| CE# | Chip enable | Active-low chip select; device enters standby when CE# high and addresses stable |
| OE# | Output enable | Active-low control for data output gating; decouples read timing from CE# assertion |
| WE# | Write enable | Active-low strobe for command latching and write operations; initiates internal program/erase sequences |
| WP#/ACC | Write protect / accelerated program | Low = hardware sector lock (first/last sector); high + VHH = accelerated programming for production throughput |
| RY/BY# | Ready/Busy indicator | Open-drain active-low output signaling completion of program/erase; eliminates need for polling in time-critical systems |
| RESET# | Hardware reset | Active-low asynchronous reset terminating any ongoing operation; synchronizes device state during system power-up |
| BYTE# | Bus width configuration | Low = 16-bit mode; high = 8-bit mode using DQ0–DQ7 only; enables flexible host interface design |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 256-byte factory- or customer-lockable region with 16-byte electronic serial number - provides immutable device identity for secure boot and anti-cloning |
| Advanced Sector Protection | Persistent and password-based protection modes - prevents accidental or unauthorized firmware overwrite without explicit unlock sequence |
| Program/Erase Suspend & Resume | Allows interrupting a sector operation to read/program another sector - enables concurrent firmware update and runtime code execution |
| CFI compliance | Standardized query structure (0x00–0x52) enabling automatic detection and configuration by host BIOS/bootloader - eliminates hard-coded flash parameters |
| Unlock Bypass Program | Two-cycle command sequence instead of four - cuts multi-word programming time by ~50% in production programming workflows |
Applications

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 - no TSOP pins, 8.15 × 6.15 mm footprint | Used where board space is constrained and reflow-compatible BGA assembly is available | Select when PCB layout requires BGA density and thermal profile supports 260°C peak reflow |
| MX29GL320EBTI-90G | 32 Mbit, 90 ns, 3 V Macronix device - JEDEC command compatible but lacks Secured Silicon Sector and Password Sector Protection | Acceptable for cost-sensitive industrial applications where cryptographic device identity is not required | Choose only if advanced security features are unnecessary and supply chain diversification is prioritized |
Compared with S29GL032N90BFI040, the BGA variant offers smaller footprint but requires different assembly infrastructure, while the Macronix part trades security features for broader distributor availability and lower unit cost in non-secure use cases.

FAQ
Is S29GL032N90BFI040 pin-compatible with earlier S29GL032N variants in TSOP packages?
Yes - S29GL032N90BFI040 uses the 48-pin TSOP Type I footprint defined in the Cypress/Infineon datasheet (001-98525 Rev. *B), matching mechanical and electrical pinout of all S29GL032N-x90Bxx TSOP variants. Pin functions, drive strengths, and timing parameters are identical across speed grades within the same package type.
Does this device require external high-voltage circuitry for programming?
No - S29GL032N90BFI040 operates from a single 3.0 V supply for all read, program, and erase functions. The WP#/ACC pin accepts VHH (typically 9–12 V) only to accelerate programming in production; standard 3 V operation fully supports field programming without external HV generators.
What is the role of the BYTE# pin, and how does it affect data bus width?
BYTE# selects between 16-bit and 8-bit data bus operation: when low, DQ0–DQ15 function as a full 16-bit bus; when high, only DQ0–DQ7 are active and DQ8–DQ15 are tri-stated, enabling compatibility with 8-bit microcontrollers or reduced-pin-count interfaces without hardware redesign.
Can the Secured Silicon Sector be reprogrammed after factory locking?
No - once the Secured Silicon Sector is permanently locked (via command sequence or factory setting), its 256-byte contents - including the 16-byte electronic serial number - become read-only and immune to erase or program commands. Unlocking is physically impossible; the sector remains intact through all subsequent device operations.
