Product details
Overview
S29GL032N11FFIV20 from Infineon Technologies (formerly Cypress) is a 32-Mbit, 16-bit wide single-power-supply MirrorBit Flash memory organized as 2,097,152 words (4,194,304 bytes), featuring 90 ns access time, 25 ns page read time, and 100,000 erase cycles per sector. It supports uniform sector architecture with sixty-four 32 Kword (64 KB) sectors and operates across VCC = 2.7–3.6 V and VIO = 1.65–3.6 V for flexible I/O voltage control in embedded boot code storage.
For engineers reviewing the S29GL032N11FFIV20 datasheet, S29GL032N11FFIV20 pinout, S29GL032N11FFIV20 application, or S29GL032N11FFIV20 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), CFI compliance, and support for Program/Erase Suspend & Resume operations in real-time firmware update systems.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling simultaneous hot-hole assisted sector erase and hot-electron injection programming. Its dual-bus operation allows 16-bit data width by default, with BYTE# input enabling optional 8-bit mode for legacy microcontroller interfaces.
The command-based interface uses standard microprocessor write timing with internal address/data latching; status monitoring is supported via DQ7 Data# Polling, DQ6/DQ2 toggle bits, and RY/BY# output. Hardware features include WP#/ACC-accelerated programming, RESET#-initiated abort/reset, and VCC detector–enabled automatic write inhibition during power transitions.
Key Specifications

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 | Lacks fine-pitch BGA footprint; requires PCB redesign for space-constrained modules | Select when board layout prioritizes reworkability over density and thermal performance |
| MX29GL32EHXFI-90G | Micron 32 Mbit Flash; 90 ns access but no Secured Silicon Sector or Password Protection | Supports basic boot code but lacks hardware security features required for regulated endpoints | Choose only for cost-sensitive consumer applications where cryptographic identity is not mandated |
Compared with S29GL032N11FFIV20, the TSOP variant trades BGA thermal/mechanical advantages for easier prototyping, while the Micron alternative omits security primitives essential for medical, automotive, and industrial certifications-making the Infineon part uniquely suited for safety-critical embedded boot storage.

FAQ
What is the function of the BYTE# pin on S29GL032N11FFIV20?
The BYTE# pin selects data bus width: logic high configures the device for 16-bit operation (DQ0–DQ15 active), while logic low enables 8-bit mode (DQ0–DQ7 only). This allows seamless integration with both modern 16-bit microcontrollers and legacy 8-bit MCUs without external multiplexing hardware, preserving PCB layout flexibility across product generations.
Does S29GL032N11FFIV20 support true 3.3 V-only operation?
Yes-S29GL032N11FFIV20 operates fully within VCC = 2.7–3.6 V and VIO = 1.65–3.6 V ranges. At VCC = 3.3 V ±0.3 V and VIO = 3.3 V, it delivers guaranteed 90 ns access time and full command functionality including Password Sector Protection and CFI queries, meeting standard 3.3 V LVTTL interface requirements without voltage translation.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region programmed and permanently locked at the factory or by the customer. It contains an 8-word electronic serial number (ESN) and cannot be erased or rewritten once secured. Unlike standard sectors, it provides immutable device identity for secure boot, anti-cloning, and regulatory traceability-verified via command sequence, not standard address mapping.
Can S29GL032N11FFIV20 be used in concurrent read-while-write (RWW) applications?
Yes-via Program Suspend and Erase Suspend commands, the device allows reading from unprotected sectors while programming or erasing others. For example, an MCU can execute code from one sector while updating firmware in another, with RY/BY# signaling and DQ6 toggle bits enabling precise timing control-validated in Infineon's AN221127 application note for real-time embedded systems.
