Product details
Overview
S25FL032P0XNFB003 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 FAST_READ at 80 MHz (40 MB/s). It supports accelerated programming via 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 S25FL032P0XNFB003 datasheet, S25FL032P0XNFB003 pinout, S25FL032P0XNFB003 application, or S25FL032P0XNFB003 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O read bandwidth, OTP programmability, and industrial temperature support (–40°C to +85°C) in WSON-8 package.
Technical Context
The S25FL032P implements a serial peripheral interface with four I/O modes: standard SPI, Dual Output Read, Quad Output Read, Dual I/O, and Quad I/O - all supporting up to 80 MHz clock rate. Its memory array is organized into 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).
Internal voltage regulation enables program/erase operations from a single 3.0-V supply; accelerated programming requires 9 V applied to W#/ACC. The device complies with Common Flash Interface (CFI) and provides JEDEC-standard two-byte Device ID plus one-byte RES signature for legacy compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB), sufficient for boot code + firmware image in resource-constrained microcontrollers |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3-V logic rails without level shifting |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s effective throughput - enables fast firmware loading |
| Erase Granularity | Sector (64 KB), sub-sector (4 KB or 8 KB) - allows fine-grained firmware patching without full chip erase |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20-year data retention - suitable for field-upgradable systems |
| OTP Capacity | 16 bytes (128-bit) factory- or user-programmable one-time programmable area - used for secure device ID or calibration data |

| 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 | Low = hardware write protection; 9 V = enables accelerated programming; I/O2 in Quad modes |
| GND | Ground Reference | Signal and power return path; exposed pad must be connected to GND with zero potential difference |
| 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: rising edge latches input, falling edge clocks output |
| HOLD#/IO3 | Hold Input / I/O3 | Pauses ongoing transfer without deselecting chip; functions as I/O3 in Quad I/O mode |
| VCC | Supply Voltage | Single 2.7–3.6 V rail powers all read/write/erase operations and internal charge pumps |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read | Enables 40 MB/s read throughput using SI, SO, W#/ACC, and HOLD# as simultaneous data lines - cuts boot time by ~2× vs standard SPI |
| Sub-sector Erase (4 KB / 8 KB) | Allows firmware differential updates within protected memory regions without disturbing adjacent code or configuration data |
| Accelerated Programming Mode | 9-V signal on W#/ACC reduces page program time to 1.5 ms typical - improves manufacturing flash programming throughput |
| Common Flash Interface (CFI) Compliance | Permits automatic detection and configuration by host bootloader without hard-coded driver assumptions |
| One-Time Programmable (OTP) Area | 16-byte secure region supports permanent device serialization or cryptographic key binding - prevents cloning or unauthorized reprogramming |

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 |
|---|---|---|---|
| S25FL064L0XNFB003 | 64-Mbit density, same WSON-8 package, 133-MHz max Quad I/O, 2.7–3.6 V, 100K cycles, 20-yr retention | Higher capacity supports larger firmware images; pin-compatible drop-in replacement with no PCB change | Select when new designs require >32 Mbit or future-proofing against firmware bloat |
| MX25L3233FZNI-10G | 32-Mbit, 104-MHz Quad SPI, 2.7–3.6 V, 100K cycles, but no OTP area or accelerated programming mode | Lacks hardware write acceleration and secure OTP - unsuitable for secure boot or high-throughput programming | Acceptable only where cost sensitivity outweighs secure ID or manufacturing programming speed requirements |
Compared with S25FL032P0XNFB003, S25FL064L0XNFB003 offers double density and higher speed with identical footprint and feature set, while MX25L3233FZNI-10G sacrifices OTP and acceleration for lower unit cost - making it viable only in non-secure, low-volume applications.

FAQ
Is S25FL032P0XNFB003 recommended for new designs?
No. Cypress explicitly designates this part as "Not Recommended for New Design" due to product retirement. The S25FL064L is the factory-recommended migration path, offering higher density, faster Quad I/O (133 MHz), and continued production support while maintaining pin and software compatibility.
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 9 V is applied to reduce page program time to 1.5 ms typical, and (3) I/O2 in Quad I/O and Quad Page Program modes - enabling four-wire high-speed data transfer.
Does S25FL032P0XNFB003 support execute-in-place (XIP)?
Yes - its Quad I/O FAST_READ mode delivers 40 MB/s effective bandwidth, enabling reliable XIP operation for ARM Cortex-M or RISC-V cores with appropriate cache and prefetch configuration, eliminating need for RAM copy before execution.
How is the OTP area secured against accidental overwrite?
The 16-byte OTP region can be permanently locked using the Write Status Register command with BP2–BP0 bits set to 111, which disables further writes to both OTP and main array. Once locked, the OTP content is immutable and survives power cycles and reboots.
