Product details
Overview
S29GL032N11FFIS42 from Infineon Technologies (formerly Cypress) is a 32 Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory with uniform sector architecture (64 × 64 KB sectors), 90 ns access time, and 100,000 erase cycles per sector - deployed in industrial control firmware storage and boot code retention applications.
For engineers reviewing the S29GL032N11FFIS42 datasheet, S29GL032N11FFIS42 pinout, S29GL032N11FFIS42 application, or S29GL032N11FFIS42 equivalent, key selection considerations include VIO-supported VersatileI/O™ operation (1.65–3.6 V), CFI compliance for host auto-configuration, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, and Secured Silicon Sector with factory-programmed 16-byte electronic serial number.
Technical Context
This device implements a JEDEC-compatible command-set interface with hardware-accelerated programming via WP#/ACC input, enabling high-throughput production programming. It supports byte/word configuration using BYTE# control and integrates hot-electron injection programming with hot-hole assisted sector erase.
The 110 nm MirrorBit process enables stable 20-year data retention and robust immunity to inadvertent writes via low-VCC detection, persistent sector protection, and password-protected sector locking - all managed through standardized command sequences without external voltage rails.
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 at VCC = 2.7–3.6 V and VIO = 2.7–3.6 V - defines maximum read latency in high-speed boot fetch |
| Erase endurance | 100,000 cycles per sector - supports field firmware updates over extended product lifetime |
| Data retention | 20 years typical at 125 °C - validated for automotive and industrial thermal environments |
| Supply voltage | Single 3.0 V supply (VCC = 2.7–3.6 V); I/O voltage independently configurable (VIO = 1.65–3.6 V) |
| Page read buffer | 8-word (16-byte) buffer enabling burst reads without address re-latching |
| Write buffer | 16-word (32-byte) buffer reducing multi-word programming overhead by >40% vs. single-word writes |
Pinout & Package
Package: 48-ball fine-pitch BGA (VBK048, 8.15 × 6.15 mm, 0.8 mm pitch). Ball grid layout conforms to JEDEC MO-245AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus supporting full 32 Mbit addressing; A-1 used as DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O bus | 16-bit bidirectional data path; functions as A-1 (MSB address) when in x16 configuration |
| CE# | Chip enable | Active-low chip select; device enters standby when CE# high and addresses stable |
| OE# | Output enable | Controls output drivers during read; independent of CE# for flexible timing control |
| WE# | Write enable | Initiates command latching and write operations; must be active for all program/erase commands |
| RESET# | Hardware reset | Aborts ongoing erase/program and returns device to read mode; tied to system reset for boot recovery |
| RY/BY# | Ready/Busy indicator | Open-drain output signaling active programming/erase; used for hardware polling instead of software status bits |
| WP#/ACC | Write protect / accelerate | Low = sector protection; high + elevated voltage = accelerated programming (factory throughput mode) |
| BYTE# | Bus width select | Low = x16 mode; high = x8 mode (DQ0–DQ7 only active); enables dual-bus compatibility |
| VIO | I/O voltage reference | Sets logic thresholds for all address/control/data pins - decouples I/O from core VCC rail |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word electronic serial number - enables secure device identification and immutable firmware signing keys |
| Advanced Sector Protection | Persistent and password-based locking - prevents unauthorized firmware modification without physical access or valid credentials |
| Program/Erase Suspend | Allows host to interrupt active programming or erasing to service higher-priority reads - critical for real-time OS boot loaders |
| CFI compliance | Enables automatic flash detection and parameter retrieval by host BIOS/bootloader - eliminates hard-coded timing tables |
| VersatileI/O™ control | VIO pin sets all input/output voltage thresholds - simplifies integration with mixed-voltage SoCs (e.g., 1.8 V I/O, 3.3 V core) |
Applications
| Industrial PLC Firmware Storage | Automotive Instrument Cluster Boot Memory |
|---|---|
|
Use Scenario: Nonvolatile storage of ladder logic programs and configuration parameters in programmable logic controllers operating at 85 °C ambient. IC Role / Device Role / Timing Role: Primary boot and runtime firmware repository with hardware reset recovery and sector-level update isolation. Use Value: 100,000 erase cycles and 20-year data retention ensure 15+ year field deployment without refresh; Secured Silicon Sector stores calibration checksums immune to overwrite. |
Use Scenario: Storing boot code and GUI assets for digital instrument clusters requiring ASIL-B compliant firmware integrity. IC Role / Device Role / Timing Role: CFI-identified boot flash with RY/BY#-driven state machine synchronization for deterministic startup timing. Use Value: Password Sector Protection prevents unauthorized UI firmware patching; 90 ns access enables sub-100 ms boot-to-display latency. |
| Medical Diagnostic Equipment Configuration | Network Router Boot Image Storage |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N10TFI020 | Same die, 48-pin TSOP package (not BGA); 110 ns access time at VIO = 1.65–3.6 V | Limited to PCBs with TSOP footprint; no fine-pitch BGA routing constraints | Select when board layout prioritizes reworkability over space efficiency and thermal performance |
| MX29GL32EHXFI-90G | Micron 32 Mbit Flash; 90 ns access, but lacks Secured Silicon Sector and CFI support | Requires custom driver development; no factory-locked serial ID or auto-configuration capability | Select only if cost sensitivity outweighs security and firmware portability requirements |
Compared with S29GL032N11FFIS42, the TSOP variant trades BGA density and thermal performance for manual assembly compatibility, while the Micron alternative sacrifices secure identification and host interoperability for marginal cost reduction - making the Infineon part optimal for certified, upgradable embedded systems.

FAQ
What is the function of the VIO pin on S29GL032N11FFIS42?
The VIO pin sets the voltage threshold for all input and output signals - including address, control, and data lines - allowing independent I/O voltage scaling from 1.65 V to 3.6 V. This enables direct interfacing with low-voltage microcontrollers or FPGAs without level shifters, while maintaining full 3.0 V core operation for reliability and noise margin.
Does S29GL032N11FFIS42 support both x8 and x16 data bus configurations?
Yes, the BYTE# pin selects bus width: asserted low enables full 16-bit operation (DQ0–DQ15 active), while high configures x8 mode (DQ0–DQ7 only). In x16 mode, DQ15 doubles as A-1 (most significant address bit), supporting seamless migration between 8-bit and 16-bit host interfaces without redesign.
How is the Secured Silicon Sector protected from modification?
The Secured Silicon Sector is permanently locked either at the factory or by the customer using a dedicated command sequence. Once locked, no erase or program commands affect its 256-byte contents - including the 16-byte electronic serial number. Protection is enforced by on-die logic, not software flags, making it immune to firmware exploits or accidental overwrites.
Can S29GL032N11FFIS42 be used in systems requiring ASIL-B compliance?
While the device itself is not ISO 26262-certified, its 20-year data retention at 125 °C, 100,000 erase cycles, hardware reset (RESET#), and RY/BY# status signaling provide foundational reliability features required for ASIL-B boot memory subsystems. System-level certification requires validation of the full flash management stack, including error detection and recovery routines.
