Product details
Overview
S29GL032N90FFIS12 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 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 secure boot code persistence and JEDEC-compatible command set execution are required.
For engineers reviewing the S29GL032N90FFIS12 datasheet, S29GL032N90FFIS12 pinout, S29GL032N90FFIS12 application, or S29GL032N90FFIS12 equivalent, key selection criteria include uniform-sector erase endurance (100,000 cycles), CFI compliance for host auto-configuration, hardware reset (RESET#) integration for system boot recovery, and WP#/ACC-enabled accelerated programming during production flash.
Technical Context
This device implements a command-set–compatible, single-power-supply NOR Flash architecture using 110 nm MirrorBit process technology. It supports byte/word configuration via BYTE# input, uses DQ7 data polling and RY/BY# output for operation status, and features Erase/Program Suspend & Resume to enable concurrent read/program operations across non-target sectors.
The Secured Silicon Sector provides 256-byte factory- or customer-lockable space with 8-word ESN; Advanced Sector Protection includes both Persistent and Password-based modes. VIO-controlled I/O levels (1.65–3.6 V) decouple interface voltage from core supply, enabling mixed-voltage system interfacing without level shifters.
Key Specifications

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–A21 | Address inputs | 22-bit address bus supporting full 32 Mbit addressing; A-1 (DQ15/A-1) multiplexed for byte mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; DQ15 doubles as A-1 in byte mode when BYTE# = low |
| CE#, OE#, WE# | Chip, Output, Write Enable controls | Independent gating enables interleaved access and eliminates bus contention in multi-device systems |
| WP#/ACC | Write Protect / Accelerated Program input | Logic-low protects first/last sector; high-voltage application (VCC + 1.5 V) reduces programming time by ~40% |
| RESET# | Hardware reset input | Asynchronous active-low signal that terminates ongoing erase/program and restores ready state for boot firmware fetch |
| RY/BY# | Ready/Busy output | Open-drain status flag indicating internal operation progress - eliminates need for software polling in real-time systems |
| BYTE# | Bus width configuration | Low = 8-bit mode (DQ0–DQ7 only active); high = 16-bit mode - supports legacy 8-bit microcontrollers |
| VIO | I/O voltage reference | Defines logic thresholds for all address, control, and data pins - enables mixed-voltage board design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFIR10 | Same die, 48-ball fine-pitch BGA (VBK048) package; no TSOP pins; 110 ns access at VIO = 1.65–2.7 V | Targeted for space-constrained PCBs with BGA-only routing; lacks RESET# and RY/BY# pins in this variant | Select when board layout requires BGA footprint and system uses software polling instead of hardware status signaling |
| MX29GL32EHXFI-90G | Macleod Technology 32 Mbit NOR Flash; 90 ns access; CFI-compliant but no Secured Silicon Sector or Password Protection | Lacks factory-programmable ESN and cryptographic sector lock; lower security assurance for regulated medical/automotive use | Select for cost-sensitive consumer applications where secure boot is not mandated and endurance >50,000 cycles suffices |
Compared with S29GL032N90FFIS12, the TSOP-packaged alternative offers identical timing and feature set with full pin compatibility, while the Macleod part trades security and endurance for lower unit cost-making it suitable only where regulatory firmware integrity requirements are absent.

FAQ
What is the function of the WP#/ACC pin on S29GL032N90FFIS12?
The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last sector against accidental erase or program; when driven to VCC + 1.5 V (typically ~4.5 V), it activates accelerated programming mode, reducing typical word programming time by approximately 40%. This dual-role pin eliminates the need for separate protection and programming voltage circuitry in system design.
Does S29GL032N90FFIS12 support 8-bit data bus operation?
Yes, it supports 8-bit operation via the BYTE# input. When BYTE# is asserted low, the device operates in 8-bit mode using only DQ0–DQ7, with DQ15 functioning as A-1 address bit. This mode maintains full command compatibility and sector protection functionality, enabling seamless integration with legacy 8-bit microcontrollers without external data bus multiplexing.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 256-byte region (128 words) that can be permanently locked at factory or by the user. Once secured, no further writes or erases are possible-even with valid unlock commands. It contains a unique 16-byte Electronic Serial Number and supports secure boot code storage. Unlike standard sectors, it cannot be erased or reprogrammed after locking, providing tamper-resistant device identity.
Is CFI compliance sufficient for automatic detection in UEFI BIOS implementations?
Yes, CFI compliance enables full UEFI BIOS auto-detection: the host reads CFI query data at address 0x55 from offset 0x10, then retrieves device geometry, timing parameters, and protection features directly from standardized CFI tables. This eliminates hardcoded flash parameters in firmware, allowing one BIOS image to support multiple S29GL-N variants and future Infineon NOR Flash generations without modification.
