Product details
Overview
S25FL032P0XMFI000 from Cypress Semiconductor is a 32-Mbit, single-supply (2.7–3.6 V) SPI Flash memory with uniform 64-KB sectors, 4-KB/8-KB sub-sectors, 256-byte page size, and Quad I/O FAST_READ up to 80 MHz (40 MB/s). It supports accelerated programming via 9-V W#/ACC pin and includes 16-byte factory- or customer-programmable OTP for secure identification. Used in embedded boot code storage and firmware update storage in industrial controllers.
For engineers reviewing the S25FL032P0XMFI000 datasheet, S25FL032P0XMFI000 pinout, S25FL032P0XMFI000 application, or S25FL032P0XMFI000 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O read bandwidth, OTP programmability, and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
The S25FL032P implements a serial peripheral interface (SPI) with support for standard, dual, and quad I/O modes-including QIOR (Quad I/O High Performance Read) and QPP (Quad Page Program)-all operating at up to 80 MHz clock rate. Its architecture features two configurable parameter blocks (top/bottom 64-KB sectors split into 32 × 4-KB sub-sectors), enabling fine-grained firmware partitioning.
Internal voltage regulation enables full 2.7–3.6 V operation for read/write without external high-voltage supplies-except for accelerated programming, which requires 8.5–9.5 V applied to W#/ACC. Memory protection uses Status Register BP2–BP0 bits and hardware W#/ACC pin control, while CFI compliance allows host system auto-detection of device geometry and timing parameters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB); sufficient for boot loader + application firmware in resource-constrained microcontrollers. |
| Supply Voltage | 2.7 V to 3.6 V; single-rail compatibility with 3.3 V logic systems and eliminates need for separate VCCQ rail. |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s effective; enables fast firmware execution from XIP-capable hosts. |
| Erase Granularity | 64-KB sector, 4-KB & 8-KB sub-sector; allows selective firmware patching without full image reflash. |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20-year data retention; suitable for field-upgradable industrial devices. |
| OTP Capacity | 16 bytes (128-bit) factory- or user-programmable; provides tamper-resistant device ID or calibration data storage. |
| Operating Temp | –40°C to +85°C (Industrial grade); validated for use in PLCs, motor drives, and edge gateways. |
Pinout & Package
Package: 8-pin SOIC (208-mil body width), RoHS-compliant, lead-free, industrial temperature grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable; must fall before any command; places device in active power mode when asserted. |
| SO/IO1 | Serial Output / I/O | Primary data output in standard mode; becomes bidirectional I/O in Dual/Quad I/O and QPP modes. |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O | Hardware write lock when low; accepts 9 V for accelerated programming; functions as I/O in Quad modes. |
| GND | Ground Reference | Signal and power return; USON/WSON packages require isolated thermal pad tied to GND at 0 mV potential difference. |
| SI/IO0 | Serial Input / I/O | Command/address/data input in standard mode; bidirectional in Dual/Quad I/O and QPP. |
| SCK | Serial Clock Input | Edge-triggered interface clock; rising edge latches input, falling edge triggers output. |
| HOLD#/IO3 | Communication Hold / I/O | Pauses ongoing transfers without chip deselect; becomes I/O in Quad I/O mode. |
| VCC | Power Supply | 2.7–3.6 V supply; internally regulated for internal high-voltage generation during programming. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s read throughput using all four I/O pins simultaneously-critical for XIP boot latency reduction. |
| Sub-sector Erase (4-KB & 8-KB) | Allows firmware updates to modify only changed functional modules without erasing entire application image. |
| One-Time Programmable (OTP) Area | 16-byte secure region supports permanent device serialization or cryptographic key binding at factory or end-user site. |
| Common Flash Interface (CFI) Compliance | Permits automatic detection of geometry, timing, and command set by host bootloader-reducing porting effort across flash vendors. |
| Accelerated Programming Mode | Reduces typical page program time to 1.5 ms using external 9-V pulse on W#/ACC-improves production programming throughput. |
Applications
| Industrial PLC Firmware Storage | Medical Device Boot Code |
|---|---|
Use Scenario: Storing real-time control firmware and configuration tables in programmable logic controllers deployed in factory automation lines. IC Role / Device Role / Timing Role: Non-volatile boot memory providing deterministic startup sequence and field-upgradable logic images.

IC Role / Device Role / Timing Role: SPI-connected firmware storage supporting AEC-Q100 Grade 3 qualification (–40°C to +85°C). Use Value: Quad I/O read speed reduces boot time below 100 ms-meeting OEM cold-start timing requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L | 64-Mbit density; same 2.7–3.6 V supply; supports 133-MHz Quad I/O; newer 65-nm process; no W#/ACC acceleration pin. | Higher capacity for larger firmware images; lacks 9-V accelerated programming; deeper power-down current reduced to 2 µA. | Select for new designs requiring extended capacity and lower standby power; migration path recommended by Cypress. |
| MX25L3233F | 32-Mbit; 2.7–3.6 V; supports 104-MHz Quad I/O; no OTP area; standard 1.5-ms page program without acceleration pin. | No secure OTP provisioning; identical sector layout but no sub-sector erase commands (P4E/P8E); lower cost in high-volume procurement. | Choose where OTP and sub-sector erase are not required; verify CFI descriptor compatibility with existing bootloader. |
Compared with S25FL032P0XMFI000, S25FL064L offers double capacity and improved power efficiency but removes accelerated programming, while MX25L3233F matches density and speed yet omits OTP and fine-grained erase-making it suitable only where security and partial-update capability are non-critical.

FAQ
Is S25FL032P0XMFI000 still in production?
No-Cypress officially retired the S25FL032P family and does not recommend it for new designs. However, Aetrix Electronics maintains legacy inventory with full traceability and supports ongoing production for existing platforms through lifecycle management programs.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin serves three roles: hardware write protection when pulled low, acceleration trigger for faster programming when pulsed to 8.5–9.5 V, and bidirectional I/O (IO2) in Quad I/O and Quad Page Program modes-enabling 4-wire high-speed data transfer.
Can the OTP area be reprogrammed after initial programming?
No-the 16-byte OTP region can be programmed once and permanently locked either at the factory or by the user via the OTP Lock instruction. Once locked, further writes to that region are blocked; unlocking is not supported per datasheet specification.
Does S25FL032P0XMFI000 support standard SPI mode 0 (CPOL=0, CPHA=0)?
Yes-it fully supports SPI Mode 0 (rising-edge sample, falling-edge setup) for all commands including READ, FAST_READ, RDSR, and PP. Dual and Quad I/O modes also operate in Mode 0, maintaining compatibility with standard SPI controllers without clock polarity or phase reconfiguration.
