Product details
Overview
S29GL032N90TFA043 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 100,000 erase cycles per sector. It operates across VCC = 2.7–3.6 V and VIO = 1.65–3.6 V, and is commonly used in industrial control firmware storage where deterministic boot code integrity and long-term data retention are required.
For engineers reviewing the S29GL032N90TFA043 datasheet, S29GL032N90TFA043 pinout, S29GL032N90TFA043 application, or S29GL032N90TFA043 equivalent, key selection criteria include uniform sector erase capability, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware reset (RESET#) support for safe boot recovery.
Technical Context
This device implements a command-set-compatible JEDEC-standard Flash interface with dual-mode operation: 16-bit wide data bus only, or configurable 8/16-bit via BYTE# input. Internal architecture includes hot-electron injection programming and hot-hole assisted sector erase, supported by on-chip voltage generators for VPP and timing control.
It integrates VersatileI/O™ logic where all input/output voltage levels are referenced to VIO (1.65–3.6 V), enabling interoperability with mixed-voltage systems. Status reporting uses DQ7 Data# Polling, DQ6/DQ2 toggle bits, and dedicated RY/BY# output - all synchronized to CE# and OE# timing windows defined in AC Characteristics tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16-bit words); supports firmware image storage up to ~4 MB in embedded boot applications. |
| Access Time | 90 ns at VCC = 2.7–3.6 V; enables direct execution from flash (XIP) in microcontroller-based systems with ≤11 MHz bus timing. |
| Sector Architecture | 64 uniform 32 Kword (64 KB) sectors; allows granular firmware updates without full chip erase, reducing field upgrade downtime. |
| Erase Endurance | 100,000 cycles per sector; validated for industrial equipment requiring >10 years of field firmware patching. |
| Data Retention | 20 years at 125°C junction temperature; ensures reliability in automotive under-hood or industrial high-temp environments. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; permits direct interfacing with 1.8 V I/O controllers while maintaining 3.3 V core read/write margins. |
| Standby Current | 1 µA typical; reduces system power budget in battery-backed or energy-harvesting edge devices during idle states. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pinout conforms to Figure 1 in datasheet Rev. *B (page 5), with NC pins present on S29GL064N but functional on S29GL032N.
| 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/word mode selection. |
| DQ0–DQ15 | Data/Address Bus | 16-bit bidirectional data bus; DQ15 doubles as A-1 for 8-bit mode when BYTE# = low. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent three-control interface enables concurrent memory mapping and avoids bus contention in multi-device systems. |
| WP#/ACC | Write Protect / Accelerated Program | Hardware lock for first/last sector; applying 5.5 V enables faster factory programming without software command overhead. |
| RESET# | Hardware Reset Input | Asynchronous active-low signal that terminates ongoing erase/program and restores device to read mode within 100 ns. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator tied to system interrupt line; asserts low during internal operations, eliminating polling latency. |
| BYTE# | Bus Width Select | Configures DQ bus as 8-bit (BYTE# = low) or 16-bit (BYTE# = high); critical for legacy 8-bit microcontroller compatibility. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word ESN; provides immutable device identity for secure boot authentication and anti-cloning. |
| Advanced Sector Protection | Persistent and Password Sector Protection modes; prevents accidental or unauthorized firmware overwrite in deployed systems without external security ICs. |
| Program/Erase Suspend | Allows host to pause active program/erase in one sector and read/program another; essential for real-time OS environments requiring background updates. |
| CFI Compliance | Standardized query table at address 0x0055; enables automatic detection and configuration by bootloader or flash translation layer (FTL) firmware. |
| VersatileI/O™ Control | VIO-referenced inputs/outputs decouple I/O voltage from VCC; simplifies integration with 1.8 V FPGAs or 3.3 V MCUs in same design. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI043 | Same die, 48-pin TSOP, but with industrial temperature range (–40°C to +85°C) vs. commercial (0°C to +70°C) for S29GL032N90TFA043. | Required for outdoor or uncontrolled-ambient deployments; not suitable for cost-sensitive consumer-grade designs. | Select when extended temperature qualification is mandated by system-level environmental specs. |
| MX29GL32EHXFI-90G | Micron 32 Mbit parallel NOR Flash; 90 ns access, 64 KB sectors, but lacks Secured Silicon Sector and CFI query table. | Acceptable for non-secure, non-autoconfigurable applications; requires custom driver development instead of CFI-based generic FTL. | Choose only if Secured Silicon and CFI are not required, and Micron's supply chain offers better lead time or pricing. |
Compared with S29GL032N90TFI043, the A043 variant trades temperature margin for lower cost in benign environments; versus MX29GL32EHXFI-90G, it delivers certified secure identity and plug-and-play host compatibility at the expense of slightly higher unit price.

FAQ
Is S29GL032N90TFA043 compatible with legacy Cypress S29GL032N designs?
Yes - it is a direct drop-in replacement with identical pinout, command set, timing parameters, and electrical characteristics. Infineon continues to manufacture and support this part under the original ordering number, including full documentation and cross-reference compatibility with prior Cypress design files and reference schematics.
Does this device support 8-bit data bus operation?
Yes, via the BYTE# input: when pulled low, the device operates in 8-bit mode using DQ0–DQ7, with DQ15 functioning as A-1 for address extension. This enables seamless integration with 8-bit microcontrollers without external data bus multiplexing logic.
What is the function of the WP#/ACC pin beyond write protection?
When a 5.5 V voltage is applied to WP#/ACC, it activates accelerated programming mode, reducing individual word programming time by up to 40%. This feature is intended for high-throughput manufacturing but can also be used in-field for rapid firmware deployment where timing constraints permit.
How is the Secured Silicon Sector protected after factory programming?
Once locked, the 128-word Secured Silicon Sector becomes permanently read-only - no command sequence, voltage condition, or physical interface can modify its contents. The 8-word Electronic Serial Number is pre-programmed and verified at wafer test; lock status is indicated by persistent bit settings readable via CFI query or dedicated command sequence.
