Product details
Overview
S25FL032P0XNFI000 from Cypress Semiconductor is a 32-Mbit, single-power-supply SPI Flash memory operating from 2.7 V to 3.6 V, featuring uniform 64-KB sectors, 4-KB/8-KB sub-sectors, 256-byte page programming, and Quad I/O read up to 80 MHz (40 MB/s effective). It supports accelerated programming via W#/ACC pin and includes 16-byte OTP for secure identification. Used in embedded boot code storage and firmware update storage in industrial controllers.
For engineers reviewing the S25FL032P0XNFI000 datasheet, S25FL032P0XNFI000 pinout, S25FL032P0XNFI000 application, or S25FL032P0XNFI000 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O throughput, OTP programmability, JEDEC CFI compliance, and industrial temperature range (–40°C to +85°C) support.
Technical Context
The S25FL032P implements a serial peripheral interface with five extended command sets: Dual Output Read (DOR), Quad Output Read (QOR), Dual I/O Read (DIOR), Quad I/O Read (QIOR), and Quad Page Program (QPP), all operating at up to 80 MHz clock rate. It uses Cypress's 0.09 µm MirrorBit® process and supports both standard and accelerated programming modes.
Memory organization comprises 64 uniform 64-KB sectors, with top/bottom parameter blocks subdivided into thirty-two 4-KB sub-sectors (or sixteen 4-KB + sixteen 8-KB via P4E/P8E commands). Protection is enforced via Status Register BP2–BP0 bits and hardware W#/ACC pin interaction, enabling selective read-only locking of memory regions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB) - sufficient for boot code, configuration data, and firmware images in resource-constrained microcontrollers. |
| Supply Voltage | 2.7 V to 3.6 V - single-rail compatibility with 3.3-V system rails without level-shifting. |
| Read Throughput | 40 MB/s effective (Quad I/O FAST_READ) - enables fast firmware loading and real-time code execution from XIP-capable hosts. |
| Erase Granularity | 4-KB sub-sector (P4E), 8-KB sub-sector (P8E), 64-KB sector (SE), bulk erase - allows fine-grained firmware patching without full device reprogramming. |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20-year data retention - suitable for field-upgradable systems requiring long service life. |
| OTP Capacity | 16 bytes (128-bit) factory- or customer-programmable - provides immutable device ID, calibration data, or security keys. |
| Operating Temp | –40°C to +85°C (Industrial grade) - validated for use in factory automation, motor drives, and outdoor edge nodes. |
Pinout & Package
Package: 8-contact WSON (6 × 8 mm), lead-free, RoHS-compliant, with exposed thermal pad (GND-connected per layout guidelines).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for SPI communication; required falling edge after power-up before command acceptance. |
| SO/IO1 | Serial Output / I/O1 | Primary data output in standard mode; bidirectional in Dual/Quad I/O modes for high-speed read/write. |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Hardware write protection when low; enables accelerated programming when driven to 9 V; serves as I/O2 in Quad modes. |
| GND | Ground Reference | Signal and power return; must be tied to PCB ground plane; central thermal pad may connect to GND if voltage delta = 0 mV. |
| SI/IO0 | Serial Input / I/O0 | Command/address/data input in standard mode; bidirectional in Dual/Quad I/O modes. |
| SCK | Serial Clock Input | Edge-triggered timing source: latches SI on rising edge, outputs SO on falling edge. |
| HOLD#/IO3 | Hold Input / I/O3 | Pauses ongoing SPI transfer without chip deselect; functions as I/O3 in Quad I/O mode. |
| VCC | Power Supply | Single 2.7–3.6 V supply; internally generates high-voltage programming pulses; no external VPP required. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s effective throughput using four bidirectional pins-reduces boot time vs. standard SPI read. |
| Sub-sector Erase (P4E/P8E) | Allows erasing 4-KB or 8-KB regions independently-preserves valid firmware while updating patches or parameters. |
| One-Time Programmable (OTP) Area | 16-byte factory- or field-programmable space-stores immutable identifiers or cryptographic keys without risk of overwrite. |
| Common Flash Interface (CFI) Compliance | Permits automatic detection and configuration by host bootloader-eliminates hard-coded flash parameters in firmware. |
| Accelerated Programming Mode | Reduces page program time to ≤1.5 ms (typical) when W#/ACC is driven to 9 V-improves production programming efficiency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L | 64-Mbit density, same 2.7–3.6 V supply, identical pinout and command set, improved 133-MHz Quad I/O speed | Supports larger firmware images and dual-application storage; requires no PCB redesign for drop-in replacement | Select when new designs require >32 Mbit capacity or higher read bandwidth; recommended migration path per Cypress documentation |
| MX25L3233F | 32-Mbit, 2.7–3.6 V, supports DTR mode up to 133 MHz, but lacks OTP area and CFI compliance | Lower-cost alternative where secure ID or bootloader auto-detection is not required | Choose only if OTP and CFI features are unused; verify hold-time and deep power-down current match system sleep requirements |
Compared with S25FL032P0XNFI000, S25FL064L offers double capacity and faster Quad I/O without layout change, while MX25L3233F trades OTP/CFI for cost reduction-making the former ideal for forward-compatible upgrades and the latter viable only in non-security-critical legacy refreshes.

FAQ
Is S25FL032P0XNFI000 still recommended for new designs?
No. Cypress explicitly states this device is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. While fully functional and supported for existing production, new projects should adopt the higher-density, faster S25FL064L to ensure long-term supply and feature alignment.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin serves three roles: (1) hardware write protect when pulled low, (2) acceleration enable when driven to 9 V for faster page programming (≤1.5 ms), and (3) I/O2 signal in Quad I/O and Quad Page Program modes-enabling four-wire high-speed data transfer without additional pins.
Can the OTP area be erased or rewritten after programming?
No. The 16-byte OTP region is permanently programmable once written; individual bits can be set from '1' to '0', but no mechanism exists to reset '0' bits back to '1'. Locking the OTP region (via OTP lock bit) prevents further writes, making it suitable for immutable identifiers or cryptographic keys.
Does S25FL032P0XNFI000 support Dual Transfer Rate (DTR) mode?
No. This device supports Single Transfer Rate (STR) SPI modes only: standard read, FAST_READ, DOR, QOR, DIOR, and QIOR-all operating in STR. DTR capability (clocking data on both edges) is absent; maximum effective throughput remains 40 MB/s via Quad I/O STR at 80 MHz.
