Product details
Overview
S29GL032N11FFIV23 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 S29GL032N11FFIV23 datasheet, S29GL032N11FFIV23 pinout, S29GL032N11FFIV23 application, or S29GL032N11FFIV23 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 16-byte ESN, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), and hardware reset (RESET#) support for reliable boot initialization.
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, CFI-compliant host identification, and simultaneous hot-hole erase / hot-electron programming mechanisms.
Its sector-erase topology enables independent reprogramming of 64 KB sectors without disturbing adjacent data. The device integrates dual status reporting (DQ7 Data# Polling and RY/BY# output) and supports suspend/resume during program or erase operations to enable concurrent read access to unprotected sectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 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 minimum read cycle timing for high-speed boot fetch |
| Erase endurance | 100,000 cycles per sector - ensures long-term field reliability in firmware update scenarios |
| Data retention | 20 years typical - guarantees nonvolatile storage integrity across product lifecycle |
| Supply voltage | Single 3.0 V supply (VCC = 2.7–3.6 V); I/O voltage independently set by VIO (1.65–3.6 V) |
| Page read buffer | 8-word (16-byte) buffer enabling burst reads with 25 ns page access time |
| Write buffer | 16-word (32-byte) buffer reducing multi-word programming overhead |
Pinout & Package
Package: 48-ball fine-pitch BGA (VBK048, 8.15 × 6.15 mm, 0.8 mm pitch). Pinout validated per Cypress document 001-98525 Rev. *B, Figure 3 (S29GL032N 48-ball BGA).
| 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 bidirectional bus | 16-bit parallel interface; DQ15 also functions as A−1 for byte/word mode selection |

| WE# | Write enable | Active-low strobe initiating command latching, programming, or erase sequences |
| RESET# | Hardware reset | Active-low asynchronous reset terminating all operations and restoring ready state |
| RY/BY# | Ready/Busy output | Open-drain status signal indicating active program/erase cycle completion |
| WP#/ACC | Write protect / accelerated program | Logic-low assertion protects first/last sector; high-voltage mode reduces programming time in production |
| BYTE# | Bus width select | Configures 16-bit or 8-bit data interface; low = 16-bit, high = 8-bit (DQ15–DQ8 disabled) |
| VIO | I/O voltage reference | Sets logic thresholds for all address, control, and data pins (1.65–3.6 V range) |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word (16-byte) random Electronic Serial Number for secure firmware binding |
| Advanced Sector Protection | Persistent Sector Protection (no VPP required) + Password Sector Protection requiring valid 16-byte password before sector modification |
| Program/Erase Suspend | Allows host to pause ongoing program/erase in one sector and read/program another - critical for real-time OS firmware updates |
| CFI compliance | Enables automatic detection and configuration by host BIOS/bootloader without hard-coded device parameters |
| Unlock Bypass mode | Reduces multi-word programming command overhead from four to two write cycles - improves system-level throughput |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N10TFIV20 | 110 ns access time (vs. 90 ns); same 48-ball BGA package and 32 Mbit density | Lower performance tier suitable where boot latency < 90 ns is not required | Select when system clock budget permits longer read cycles and cost optimization is prioritized |
| MX29GL320EBTI-90G | Macronix part; identical 32 Mbit, 90 ns, 48-ball BGA; differs in CFI query structure and password unlock sequence | Requires minor bootloader adaptation due to command set variations in sector protection flow | Choose for second-source assurance where Infineon supply continuity requires diversification |
Compared with S29GL032N11FFIV23, the S29GL032N10TFIV20 trades 20 ns read speed for lower cost in static firmware storage, while MX29GL320EBTI-90G offers functionally equivalent timing and packaging but demands firmware-level validation of CFI and password command handling.

FAQ
Is S29GL032N11FFIV23 pin-compatible with earlier S29GL032N variants in the same package?
Yes - all S29GL032N variants sharing the 48-ball fine-pitch BGA (VBK048) package have identical pinouts and mechanical dimensions. Signal definitions, power requirements, and timing parameters remain consistent across speed grades and revisions, enabling drop-in replacement within the same speed bin (e.g., 90 ns models).
What is the function of the VIO pin, and how does it affect system design?
VIO sets the voltage reference for all input thresholds and output drive levels. When VIO = 1.8 V, the device interfaces directly with 1.8 V logic without level shifters; at VIO = 3.3 V, it matches standard 3.3 V microcontroller buses. This eliminates external voltage translation and simplifies mixed-voltage board design while maintaining JEDEC compatibility.
How does the Secured Silicon Sector differ from standard protected sectors?
The Secured Silicon Sector is a dedicated 256-byte region with factory-programmed 16-byte Electronic Serial Number and permanent lock capability. Unlike software-protected sectors, it cannot be erased or rewritten once locked - even with full command access - making it suitable for immutable device identity and cryptographic key storage.
Can S29GL032N11FFIV23 operate in 8-bit mode, and what is required to configure it?
Yes - asserting BYTE# = HIGH configures the device for 8-bit data bus operation, disabling DQ15–DQ8 and using only DQ7–DQ0. Address lines remain unchanged; A0–A20 continue to provide full 32 Mbit addressing. This mode is fully supported in both read and program operations and maintains all timing specifications.
