Product details
Overview
S25FL032P0XNFI001 from Cypress Semiconductor is a 32-Mbit, single-supply (2.7–3.6 V) SPI NOR 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 industrial embedded boot code storage and firmware update storage.
For engineers reviewing the S25FL032P0XNFI001 datasheet, S25FL032P0XNFI001 pinout, S25FL032P0XNFI001 application, or S25FL032P0XNFI001 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).
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. It uses Cypress's 0.09 µm MirrorBit® process and integrates CFI compliance for host system auto-configuration.
Memory architecture features 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 logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB), directly maps to boot image or firmware partition size in microcontroller-based systems |
| Supply Voltage | 2.7 V to 3.6 V - enables direct integration with 3.3-V logic rails without level-shifting |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s effective - reduces firmware load latency vs. standard SPI |
| Erase Granularity | Sector (64 KB), sub-sector (4 KB or 8 KB) - allows fine-grained firmware patching without full bulk erase |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20-year data retention - suitable for field-upgradable devices |
| OTP Capacity | 16 bytes (128-bit) factory- or user-programmable area - used for unique device ID or cryptographic key binding |
| Power Modes | Standby: 80 µA typ.; Deep Power-Down: 3 µA typ. - enables low-power operation in battery-backed systems |
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 | Active-low enable for SPI command execution; required falling edge after power-up before first command |
| SO/IO1 | Serial Output / I/O1 | Primary data output in standard mode; bidirectional in Dual/Quad I/O modes for high-speed reads |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Hardware write protection when low; enables accelerated programming when driven to 9 V; I/O in Quad modes |
| SI/IO0 | Serial Input / I/O0 | Command/address/data input in standard mode; bidirectional in Dual/Quad I/O and QPP operations |
| SCK | Serial Clock | Edge-triggered timing source: rising edge latches input, falling edge triggers output |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing SPI transaction without chip deselect; 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; internal charge pumps generate programming voltages |
| GND | Ground | Reference for all I/O and internal circuitry; exposed pad must be connected to GND with zero voltage differential |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s effective throughput using SI/SO/W#/HOLD# as parallel data lines - cuts boot time by ~4× vs. standard SPI |
| Sub-sector Erase (4 KB / 8 KB) | Allows firmware delta updates within protected memory regions without disturbing adjacent code or configuration data |
| One-Time Programmable (OTP) Area | 16-byte user-accessible space with OTPP/OTPR commands - supports secure device binding or calibration data locking |
| Common Flash Interface (CFI) Compliance | Permits automatic detection and configuration by host bootloader without hard-coded driver parameters |
| Accelerated Programming Mode | 9-V signal on W#/ACC pin reduces page program time to 1.5 ms (typ.) - improves production programming efficiency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L | 64-Mbit density, same 2.7–3.6 V supply, enhanced 133-MHz Quad I/O, improved 200K-cycle endurance | Direct migration path recommended by Cypress for new designs; requires PCB footprint adaptation for larger density | Select when higher capacity and extended lifecycle are required; verify layout compatibility with 8-pin SO/WSON footprints |
| MX25L3233F | 32-Mbit, 3 V, 104-MHz Quad I/O, no W#/ACC acceleration pin, 100K-cycle endurance, different OTP structure | Drop-in replacement in 8-pin SO/WSON packages; lacks accelerated programming and CFI compliance | Choose for cost-sensitive industrial designs where accelerated programming and CFI are not required |
Compared with S25FL032P0XNFI001, S25FL064L offers double capacity and higher performance but requires design revision, while MX25L3233F provides pin-compatible 32-Mbit functionality without acceleration or CFI - making it suitable for simpler, lower-cost implementations.

FAQ
Is S25FL032P0XNFI001 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. It remains available for legacy support and last-time buys, with full datasheet compliance and documented lifecycle status through Infineon's product change notifications.
What package does S25FL032P0XNFI001 use?
S25FL032P0XNFI001 uses the 8-contact WSON package (6 × 8 mm), identified by the 'N' in the part number suffix. Pinout matches standard SPI: CS#, SO/IO1, W#/ACC/IO2, GND, SI/IO0, SCK, HOLD#/IO3, VCC - with an exposed thermal pad tied to GND.
Does this device support Quad I/O read and write operations?
Yes. It supports Quad I/O High Performance Read (QIOR) and Quad Page Program (QPP) using SI/IO0, SO/IO1, W#/ACC/IO2, and HOLD#/IO3 as bidirectional data lines. Both operate at up to 80 MHz clock rate, delivering 40 MB/s effective read bandwidth.
How is memory protection implemented on this Flash device?
Protection uses dual mechanisms: hardware W#/ACC pin (low = write/erase inhibit) and Status Register BP2–BP0 bits that configure sector-level read-only lock. Combined, they allow selective protection of boot sectors while permitting runtime updates to application partitions.
