Product details
Overview
S29GL032N90BFI033 from Infineon Technologies (formerly Cypress) is a 32 Mbit (4,194,304-byte), 16-bit-wide single-supply MirrorBit Flash memory IC with 90 ns access time, uniform sector architecture (64 × 64 KB sectors), and Secured Silicon Sector for factory-programmed 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 deterministic boot code integrity and long-term data retention are required.
For engineers reviewing the S29GL032N90BFI033 datasheet, S29GL032N90BFI033 pinout, S29GL032N90BFI033 application, or S29GL032N90BFI033 equivalent, key selection criteria include JEDEC-compliant command set, 100,000 erase cycles per sector, CFI interface support, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, and WP#/ACC-enabled accelerated programming for production throughput.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It supports both uniform and boot-sector configurations-this part is uniform (64 sectors × 64 KB)-and uses command-based operations latched via standard microprocessor write timing without external high-voltage generators.
The VersatileI/O™ control scheme decouples I/O voltage (VIO = 1.65–3.6 V) from core supply (VCC = 2.7–3.6 V), enabling interoperability with mixed-voltage host systems. Sector-level erase, program suspend/resume, and Advanced Sector Protection (Persistent and Password modes) are implemented in on-die state machines, not external logic.
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 max at VCC = 2.7–3.6 V and VIO = 2.7–3.6 V - defines worst-case read latency for boot code fetch |
| Erase endurance | 100,000 cycles typical per sector - enables field firmware updates over product lifetime |
| Data retention | 20 years typical at 125 °C - validated for extended operation in industrial temperature environments |
| Supply voltage | VCC = 2.7–3.6 V; VIO = 1.65–3.6 V - allows direct interfacing with 1.8 V or 3.3 V I/O domains |
| Page read buffer | 8-word (16-byte) buffer with 25 ns page access - reduces sequential read latency in burst instruction fetch |
| Write buffer | 16-word (32-byte) buffer - cuts multi-word programming time by minimizing command overhead |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), lead pitch 0.5 mm, body size 12 × 20 mm - compatible with standard reflow profiles and automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 32 Mbit addressing; A-1 used as DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; supports BYTE#-controlled 8-bit mode when required |
| CE#, OE#, WE# | Chip, output, and write enable controls | Independent gating enables interleaved reads/writes and eliminates bus contention |
| WP#/ACC | Write protect / accelerated program input | Low-active hardware lock for first/last sector; high-voltage mode shortens factory programming time |
| RESET# | Hardware reset input | Asynchronous active-low signal that terminates ongoing erase/program and restores read mode |
| RY/BY# | Ready/Busy open-drain output | Indicates internal operation status; drives low during erase/program, high when idle or ready |
| VIO | I/O voltage reference | Defines logic thresholds for all address, control, and data pins - decoupled from VCC for mixed-voltage design |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word electronic serial number - prevents cloning and enables secure device identification |
| Program Suspend/Resume | Pause active programming in one sector to read from another - enables real-time diagnostics during firmware update |
| Erase Suspend/Resume | Interrupt sector erase to read or program elsewhere - avoids system freeze during background flash maintenance |
| CFI compliance | JEDEC-standard Common Flash Interface - allows automatic detection and configuration by bootloader without hard-coded parameters |
| Unlock Bypass mode | Two-cycle command sequence replaces four-cycle standard programming - reduces firmware update time by ~30% in multi-word writes |
Applications
| Industrial PLC Firmware Storage | Medical Device Boot Code Retention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL032N90TFI020 | Same die, 48-ball fine-pitch BGA (VBK048) package - no TSOP pins, smaller footprint (8.15 × 6.15 mm) | Used where board space is constrained and BGA rework capability exists; lacks through-hole TSOP compatibility | Select for compact, high-density designs; verify thermal pad layout and reflow profile for BGA reliability |
| MX29GL32EHXFI-90G | Micron 32 Mbit NOR Flash, 90 ns access, but uses different command set and lacks Secured Silicon Sector | Requires firmware driver rewrite; no factory-programmed ESN or password protection - unsuitable for secure boot | Choose only if CFI compatibility and security features are not required; confirm JEDEC command mapping divergence |
Compared with S29GL032N90BFI033, the BGA variant offers space savings but sacrifices TSOP assembly flexibility, while the Micron alternative trades security and command compatibility for second-source availability - neither is drop-in replaceable without hardware or software revision.

FAQ
What is the function of the VIO pin on S29GL032N90BFI033?
The VIO pin sets the voltage threshold for all input and output signals (address, control, and DQ lines), independent of VCC. With VIO ranging from 1.65 V to 3.6 V, it enables direct interfacing with 1.8 V or 3.3 V host processors without level shifters - critical for mixed-voltage system integration.
Does S29GL032N90BFI033 support byte-wide data access?
Yes, when the BYTE# pin is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with A0–A20 providing address bits. This mode is fully supported in both read and write operations and maintains full sector protection and CFI functionality.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed at the factory with a unique 8-word electronic serial number. Once locked, it cannot be erased or rewritten - even by command - providing immutable device identity for anti-counterfeiting and secure provisioning.
Can S29GL032N90BFI033 be used in place of older S29GL032P models?
No - the S29GL032N uses a different command set, lacks the VPP pin, and has updated timing parameters (e.g., 90 ns vs. 100 ns access). Pin compatibility exists, but firmware must be updated to match the N-series command sequences and status polling behavior (DQ7/DQ6).
