Product details
Overview
S29GL032N11FFIV12 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 64 KB uniform sectors, 90 ns access time, and 100,000 erase cycles per sector - deployed in industrial control firmware storage, boot code retention, and embedded system configuration memory.
For engineers reviewing the S29GL032N11FFIV12 datasheet, S29GL032N11FFIV12 pinout, S29GL032N11FFIV12 application, or S29GL032N11FFIV12 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 16-byte ESN, VIO-supported VersatileI/O™ operation (1.65–3.6 V), and hardware reset (RESET#) integration for boot reliability.
Technical Context
This device implements a command-set-compatible, single-supply NOR Flash architecture with hot-electron injection programming and hot-hole assisted sector erase. It supports both 16-bit and byte-wide (via BYTE#) data bus operation and integrates CFI-compliant identification for host system auto-configuration.
Its Advanced Sector Protection includes Persistent Sector Protection (PPB lock bit) and Password Sector Protection (8-word password), while Erase/Program Suspend & Resume enables concurrent read/program operations across unprotected sectors - critical for real-time firmware updates without halting system execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16-bit words), enabling full boot image + parameter storage in one device |
| Access Time | 90 ns at VCC = 2.7–3.6 V, supporting deterministic timing in real-time microcontroller interfaces |
| Sector Architecture | 64 uniform 32 Kword (64 KB) sectors, allowing granular firmware partitioning and field update safety |
| Erase Endurance | 100,000 cycles per sector, validated for industrial lifecycle requirements (e.g., PLC firmware revision logging) |
| Data Retention | 20 years typical at 125 °C, ensuring long-term reliability in automotive under-hood or industrial ambient conditions |
| VIO Range | 1.65–3.6 V, enabling direct interface to mixed-voltage SoCs without level shifters |
| Supply Voltage | Single 3.0 V supply (2.7–3.6 V), eliminating need for auxiliary voltage rails in compact designs |
Pinout & Package
Package: 48-ball fine-pitch BGA (VBK048, 8.15 × 6.15 mm), RoHS-compliant, with 0.5 mm ball pitch and bottom-side thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus supporting full 32 Mbit addressing (A20 used only on S29GL064N; NC on S29GL032N) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; DQ15 also functions as A−1 for byte-mode addressing when BYTE# = low |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent control lines enabling standard microprocessor timing and multi-device bus arbitration |
| RESET# | Hardware Reset | Asynchronous active-low input that terminates ongoing erase/program and restores device to read mode |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active programming/erasing; used for polling-free operation |
| WP#/ACC | Write Protect / Accelerated Program | Low-active write protection for first/last sector; high-voltage mode (VHH) enables faster factory programming |
| BYTE# | Bus Width Select | Configures 16-bit (BYTE# = high) or 8-bit (BYTE# = low) data interface, matching legacy or space-constrained controllers |
| VIO | I/O Supply Reference | Defines logic threshold for all address/control/data pins - decouples I/O voltage from core VCC |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word ESN for secure device identity binding |
| Program/Erase Suspend | Allows host to pause active program/erase in one sector and read/program another - essential for multitasking firmware loaders |
| CFI Compliance | Enables automatic detection of device geometry, timing, and protection features by host BIOS or bootloader without hard-coded parameters |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word, cutting total flash update time by ~50% |
| Hardware Data Protection | Low-VCC detector disables writes during power ramp-up/down, preventing corruption during brown-out or cold-start conditions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90FFIV10 | Same die, 90 ns access time, but 48-pin TSOP package (not BGA); no VIO support (fixed 3.0 V I/O) | Limited to board layouts with TSOP footprint and no mixed-voltage signaling | Select when PCB layout constraints preclude BGA or when VIO flexibility is unnecessary |
| MX29GL32EHXFI-90G | Macronix 32 Mbit NOR Flash; 90 ns access, 48-ball BGA, but lacks Secured Silicon Sector and Password Protection | Cannot support secure device identity or password-locked configuration sectors | Choose for cost-sensitive, non-security-critical applications where CFI and JEDEC compatibility suffice |
Compared with S29GL032N11FFIV12, the TSOP variant trades package flexibility and VIO adaptability for simpler assembly, while the Macronix alternative sacrifices security features for lower unit cost - making the original optimal for secure, mixed-voltage, BGA-based industrial designs.

FAQ
What is the function of the VIO pin on S29GL032N11FFIV12?
VIO sets the input/output voltage reference for all address, control, and data pins - independent of VCC. With VIO ranging from 1.65 V to 3.6 V, it enables direct interfacing to 1.8 V or 3.3 V host processors without external level shifters, reducing BOM count and signal integrity risk.
Does S29GL032N11FFIV12 support byte-wide data access?
Yes. When BYTE# is driven low, the device operates in 8-bit mode: DQ0–DQ7 become active data lines, and DQ8–DQ15 are tri-stated. This allows compatibility with 8-bit microcontrollers or legacy designs, while retaining full 16-bit performance when BYTE# is high.
How is the Secured Silicon Sector protected from accidental overwrite?
The Secured Silicon Sector is permanently locked via a one-time-programmable fuse or persistent lock bit. Once secured, no command sequence - including chip erase - can modify its contents. Factory-programmed 16-byte ESN remains readable but unwritable, providing immutable device identity for secure boot chains.
Can S29GL032N11FFIV12 be used in place of older S29GL032P devices?
No. The S29GL032N uses MirrorBit technology on 110 nm process with different command set timing and VIO dependency, whereas S29GL032P is based on older 130 nm process and lacks VersatileI/O™ and Secured Silicon features. Pinout and voltage ranges differ - direct substitution requires full hardware and firmware validation.
