Product details
Overview
S29GL032N90FFIS23 from Infineon Technologies (formerly Cypress) is a 32-Mbit (4,194,304-byte), 16-bit-wide single-power-supply MirrorBit Flash memory IC with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed 128-word 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 S29GL032N90FFIS23 datasheet, S29GL032N90FFIS23 pinout, S29GL032N90FFIS23 application, or S29GL032N90FFIS23 equivalent, key selection criteria include JEDEC-compliant command set compatibility, hardware write protection via WP#/ACC, CFI support 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 NAND-like cell architecture enabling simultaneous hot-hole erase across full sectors and hot-electron programming. It supports both uniform and boot-sector configurations - this part is uniform (64 × 64 KB sectors), with no dedicated boot blocks.
It features VersatileI/O™ control: all input thresholds and output drive levels scale with VIO (1.65–3.6 V), enabling direct interfacing to 1.8 V, 2.5 V, or 3.3 V logic without level shifters. Status reporting uses DQ7 polling, DQ6/DQ2 toggling, and RY/BY# active-low open-drain output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 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 and VIO = 2.7–3.6 V - enables direct connection to legacy 10 MHz bus systems |
| Sector Architecture | Uniform: 64 sectors × 64 KB - simplifies firmware partitioning and eliminates boot-sector address translation logic |
| Erase Endurance | 100,000 cycles typical per sector - supports field firmware updates over 10+ years in deployed equipment |
| Data Retention | 20 years typical at 125 °C - validated for industrial temperature-grade operation without refresh |
| Supply Voltage | VCC = 2.7–3.6 V; VIO = 1.65–3.6 V - allows mixed-voltage system integration with 1.8 V I/O and 3.3 V core rails |
| Page Read Buffer | 8-word (16-byte) page buffer - reduces sequential read latency by eliminating repeated address setup overhead |
Pinout & Package
Package: 48-pin TSOP (Type 1, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch). Pin functions conform to JEDEC MO-142AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus; A-1 multiplexed with DQ15 for x16 mode - supports full 32 Mbit addressing without external demux |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; DQ15 doubles as A-1 in x16 configuration - eliminates need for separate address/data bus separation logic |
| CE#, OE#, WE# | Chip, Output, Write Enable controls | Independent three-control architecture - enables concurrent memory-mapped and I/O-mapped access in microcontroller systems |
| WP#/ACC | Write Protect / Accelerated Program input | Logic-low WP# protects first/last sector; high-voltage ACC on same pin reduces program time during manufacturing - dual-function pin saves PCB real estate |
| RY/BY# | Ready/Busy# status output | Active-low open-drain signal - directly interfaces to microcontroller GPIO with pull-up; asserts low during erase/program to block host access |
| RESET# | Hardware reset input | Asynchronous active-low reset - terminates ongoing operations and returns device to read mode; ties cleanly to system power-on reset circuitry |
| VIO | I/O supply voltage reference | Defines input threshold and output drive strength - decouples I/O voltage from core VCC, enabling mixed-signal SoC interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word ESN - provides immutable device identity for secure boot and license binding |
| Advanced Sector Protection | Persistent and Password Sector Protection modes - disables program/erase in selected sectors without requiring external EEPROM or fuse bits |
| Program/Erase Suspend | Pause active program or erase to read/program other sectors - enables real-time firmware update without halting system operation |
| CFI Compliance | JEDEC JESD68-defined parameter tables accessible via command - allows host bootloader to auto-detect geometry, timing, and protection features |
| Unlock Bypass Mode | Two-cycle instead of four-cycle command sequence for multi-word programming - cuts flash programming overhead by ~50% in production test environments |

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, 56-pin TSOP package with different thermal pad layout and lead finish (SnAgCu vs SnPb) | Requires PCB footprint redesign; identical timing and command set | Select when board layout accommodates larger 56-pin TSOP and RoHS-compliant soldering is mandated |
| MX29GL32EHXFI-90G | Macleod-based 32 Mbit Flash; 90 ns access but no Secured Silicon Sector or CFI support | Lacks factory-programmable ESN and auto-configuration capability - requires fixed host driver | Choose only if Secured Silicon and CFI are unnecessary and cost is primary constraint |
Compared with S29GL032N90FFIS23, the TSOP variant S29GL032N90TFI020 offers identical functionality in a mechanically distinct package, while the Macronix MX29GL32EHXFI-90G sacrifices security and configurability for lower unit cost - making it unsuitable for certified or field-upgradable systems.

FAQ
Is S29GL032N90FFIS23 compatible with legacy Cypress S29GL032N designs?
Yes. This part retains identical pinout, command set, timing specifications, and electrical characteristics as the original Cypress S29GL032N. Infineon maintains full backward compatibility, including identical AC/DC parametric limits and JEDEC-standard software protocols. No PCB or firmware changes are required for drop-in replacement.
What is the function of the WP#/ACC pin during normal operation?
When held low, WP#/ACC permanently protects the first or last 64 KB sector from program and erase commands - even during accelerated programming. When driven high with 5.5 V (via external charge pump), it enables faster internal programming voltage generation, reducing write time by up to 40% in production test environments.
Does S29GL032N90FFIS23 support byte-level writes?
No. It is a 16-bit-wide NOR Flash with word-level (16-bit) programming granularity. The BYTE# input allows optional 8-bit data bus operation by masking DQ8–DQ15, but internal programming always occurs in 16-bit units. Single-byte modification requires full-word read-modify-write cycles managed by host firmware.
How is the Secured Silicon Sector programmed and locked?
The 128-word Secured Silicon Sector is programmed using the Enter Secured Silicon Sector command (0x80 → 0x60 → 0x80 → 0x60), then written like standard flash. Locking is performed via the Persistent Protection Bit (PPB) lock command (0x80 → 0x60 → 0x01), which permanently disables further writes to that sector - irreversible without factory reprogramming.
