Product details
Overview
S29GL032N90FFA040 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 3.0-V single-power-supply MirrorBit Flash memory organized as 2,097,152 words (4,194,304 bytes), featuring 90 ns access time, 64 KB uniform sector architecture (64 sectors), and Secured Silicon Sector with factory-programmable 128-word electronic serial number. It operates across VCC = 2.7–3.6 V and VIO = 1.65–3.6 V, and is used in embedded boot code storage for industrial controllers requiring deterministic read latency and field-upgradable firmware.
For engineers reviewing the S29GL032N90FFA040 datasheet, S29GL032N90FFA040 pinout, S29GL032N90FFA040 application, or S29GL032N90FFA040 equivalent, key selection criteria include JEDEC-compliant command set compatibility, hardware write protection via WP#/ACC, CFI compliance for host auto-configuration, and support for program/erase suspend-resume operations in real-time systems.
Technical Context
This device implements a 16-bit wide data bus (with BYTE# configurable for 8-bit mode), uses hot-electron injection for programming and hot-hole assisted erase per sector, and supports both uniform and boot-sector architectures - though the S29GL032N90FFA040 variant is uniform (64 × 64 KB sectors). Its VersatileI/O™ control ties all input/output voltage thresholds to VIO, enabling mixed-voltage system interfacing.
Command execution relies on internal latching of addresses and data during write cycles; status is monitored via DQ7 polling, DQ6/DQ2 toggle bits, or RY/BY# output. Advanced protection includes Persistent Sector Protection (PPB-based) and Password Sector Protection, both implemented in dedicated lock registers accessible only through defined command sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16-bit words); sufficient for full boot loader + configuration tables in resource-constrained microcontrollers. |
| Access Time | 90 ns at VCC = 2.7–3.6 V; enables direct execution from flash (XIP) in systems with ≤11 MHz bus timing budgets. |
| Sector Architecture | 64 uniform 64 KB sectors; simplifies firmware partitioning and OTA update management without boot-sector complexity. |
| Erase Endurance | 100,000 cycles per sector; supports >10 years of field firmware updates at one sector rewrite per month. |
| Data Retention | 20 years at 125°C; validated for automotive under-hood and industrial high-temperature environments. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct interface to 1.8 V or 3.3 V I/O domains without level shifters. |
| Standby Current | 1 µA typical; meets ultra-low-power requirements for battery-backed or energy-harvesting edge nodes. |
Pinout & Package
Package: 48-pin TSOP (Type 1, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) multiplexed for byte-mode selection. |
| DQ0–DQ15 | Data/Address Bus | 16-bit bidirectional data bus; DQ15 doubles as A-1 in byte mode when BYTE# = low. |
| CE# | Chip Enable | Active-low chip select; device enters standby when CE# high, enabling multi-device memory mapping. |
| OE# | Output Enable | Active-low read strobe; decouples read timing from CE#, allowing overlapping address setup. |
| WE# | Write Enable | Active-low write strobe; initiates command latching or data programming based on address sequence. |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector lock (first/last sector); high + VHH = accelerated programming for production throughput. |
| RY/BY# | Ready/Busy Output | Open-drain active-low signal indicating ongoing program/erase; eliminates need for polling in interrupt-driven systems. |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates any operation and returns device to read mode for safe reboot recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with unique 8-word electronic serial number; enables secure device identity binding in IoT gateways. |
| Program/Erase Suspend-Resume | Pause active programming or erasing to service higher-priority reads from other sectors; essential for real-time OS firmware updates. |
| CFI Compliance | Standardized query structure at address 0x55, enabling automatic detection and parameter loading by bootloader without hard-coded offsets. |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word; cuts flash programming time by ~40% in production test. |
| Hardware Data Protection | On-chip VCC detector inhibits writes during brown-out; prevents corruption during power ramp-up/down in unregulated power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-Mbit parallel NOR Flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29GL32EHXFI-90G | 90 ns access, 48-pin TSOP, but lacks Secured Silicon Sector and Password Sector Protection; uses standard JEDEC-only command set. | No hardware-enforced device identity or password-protected sector locking; requires external security controller for secure boot. | Select when cost sensitivity outweighs secure identity needs and legacy JEDEC-only toolchains are in use. |
| S29GL032S90TFI010 | Same MirrorBit core, but 56-pin TSOP package with additional NC pins; identical timing and feature set except no WP#/ACC dual function (separate WP# and ACC pins). | Requires PCB redesign for pinout; supports same suspend/resume and CFI features but offers no VIO flexibility advantage in 56-pin variant. | Select only when board layout accommodates 56-pin TSOP and separate WP#/ACC routing is preferred for noise isolation. |
Compared with MX29GL32EHXFI-90G and S29GL032S90TFI010, the S29GL032N90FFA040 uniquely integrates factory-programmable electronic serial number and dual-mode WP#/ACC in a 48-pin TSOP, delivering secure identity and production-accelerated programming without package or command-set trade-offs.

FAQ
Is S29GL032N90FFA040 compatible with legacy Cypress S29GL032N designs?
Yes - this part retains identical pinout, command set, timing parameters, and electrical characteristics as the original Cypress S29GL032N90FFA040. Infineon guarantees full form-fit-function compatibility, including identical AC/DC specifications and CFI query responses, ensuring drop-in replacement without design revision.
What is the function of the WP#/ACC pin during normal operation versus programming?
When held low, WP#/ACC permanently protects the first or last sector against accidental erase/write. When driven high with VHH (≈9 V), it activates accelerated programming mode, reducing individual word programming time by ~30% - intended for high-throughput manufacturing, not field use.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with a unique 8-word electronic serial number at the factory. Once locked via command sequence, it becomes permanently read-only and immune to bulk erase - providing tamper-resistant device identity for secure boot and licensing.
Can S29GL032N90FFA040 operate in 8-bit data bus mode?
Yes - asserting BYTE# low configures DQ0–DQ7 as the data bus while DQ8–DQ15 become high-impedance; A-1 functionality moves to DQ15. This enables compatibility with 8-bit microcontrollers without external data bus multiplexing logic.
