Product details
Overview
S25FL032P0XNFB001 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 for industrial microcontrollers.
For engineers reviewing the S25FL032P0XNFB001 datasheet, S25FL032P0XNFB001 pinout, S25FL032P0XNFB001 application, or S25FL032P0XNFB001 equivalent, key selection factors include sub-sector erase granularity (4 KB/8 KB), JEDEC-compliant CFI interface, dual/quad I/O read modes, 100,000 program/erase cycles, and industrial temperature range (–40°C to +85°C).
Technical Context
The S25FL032P implements a serial peripheral interface (SPI) with support for standard, fast, dual-output, quad-output, dual-I/O, and quad-I/O read commands. It uses a 0.09 µm MirrorBit® process and integrates status/configuration registers with block protection bits (BP2–BP0) for hardware-based memory locking.
It features dedicated OTP space (16 bytes + 490 bytes), programmable via OTPP/OTPR instructions, and supports accelerated programming only when ≥9 V is applied to W#/ACC. Erase operations include sector (64 KB), sub-sector (4 KB or 8 KB), and bulk erase - all executed via discrete SPI commands (D8h, 20h, 40h, C7h).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB), organized as 64 × 64-KB sectors with top/bottom parameter blocks split into 4-KB or 8-KB sub-sectors |
| Supply Voltage | 2.7 V to 3.6 V - enables direct integration with 3.0-V system rails without level-shifting or auxiliary supplies |
| Read Throughput | 40 MB/s effective (QUAD I/O FAST_READ at 80 MHz) - doubles bandwidth over standard SPI for boot image loading |
| Program/Erase Endurance | 100,000 cycles per sector - supports field firmware updates in industrial control applications |
| Data Retention | 20 years typical - ensures long-term reliability in unattended equipment such as remote sensors |
| OTP Capacity | 16 bytes one-time programmable area + 490 bytes additional OTP - provides secure device ID and calibration data storage |
| Power Consumption | 3 µA typical in Deep Power-Down mode - critical for battery-backed systems requiring ultra-low standby current |
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; required falling edge after power-up before command acceptance; places SO in high-Z when deasserted |
| SO/IO1 | Serial Output / I/O1 | Primary data output in standard/fast read; becomes bidirectional I/O in dual/quad I/O modes |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Hardware write lock when low; enables accelerated programming at ≥9 V; serves as I/O2 in quad modes |
| GND | Ground Reference | Signal and power return; exposed pad must be connected to GND with zero voltage differential per layout spec |
| SI/IO0 | Serial Input / I/O0 | Latches commands/addresses/data on rising SCK edge; functions as I/O0 in dual/quad I/O and QPP modes |
| SCK | Serial Clock | Drives timing for all SPI transactions; rising edge latches input, falling edge triggers output |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing transfers without CS# toggle; acts 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 |
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 - reduces boot time vs. standard SPI |
| Sub-sector Erase (4 KB / 8 KB) | Allows selective firmware patching without erasing full 64-KB sectors - preserves configuration data during OTA updates |
| JEDEC CFI Compliance | Permits automatic flash detection and parameter negotiation by host bootloader - eliminates hard-coded timing assumptions |
| Accelerated Programming Mode | Reduces page program time to ≤1.5 ms (typical) when 9 V applied to W#/ACC - improves production programming efficiency |
| Hardware Memory Protection | Status register BP2–BP0 bits + W# pin enable lock-down of boot sectors against accidental overwrite - enhances system security |

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, but newer 65 nm process and improved 133 MHz max clock rate | Supports larger firmware images and dual-die stacking; not pin-compatible with all S25FL032P package variants (e.g., USON) | Select for new designs requiring higher capacity or longer product lifecycle; migration path officially endorsed by Cypress |
| MX25L3233F | 32-Mbit, 2.3–3.6 V supply, supports DTR mode, no W#/ACC acceleration pin, 65 nm process, 100,000-cycle endurance | Lacks OTP area and sub-sector erase (only 4-KB sectors); requires different status register handling for protection | Use where cost sensitivity outweighs need for accelerated programming or secure OTP; verify hold-time compatibility in existing PCB layouts |
Compared with S25FL032P0XNFB001, S25FL064L offers double capacity and extended longevity but requires layout review for BGA variants, while MX25L3233F trades OTP and sub-sector flexibility for broader voltage tolerance and lower unit cost in volume production.

FAQ
Is S25FL032P0XNFB001 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the official migration path. While functional and available through legacy channels, it lacks long-term roadmap support and newer process benefits like lower power or higher speed.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin enables accelerated programming mode when ≥9 V is applied, reducing typical page program time to 1.5 ms. In dual/quad I/O and quad page program modes, it serves as IO2 - a bidirectional data line, not just a control signal.
Can the OTP area be reprogrammed after initial programming?
No. The 16-byte primary OTP region is one-time programmable and permanently locked after programming. Once written and locked (via OTP Lock command), bits cannot be altered. The additional 490-byte OTP space also supports one-time write-and-lock behavior.
Does S25FL032P0XNFB001 support XIP (eXecute-In-Place) directly?
It does not natively support XIP - the device requires external address translation and caching logic. However, its Quad I/O FAST_READ mode enables high-speed sequential reads that, when paired with an MCU's SPI memory-mapped controller (e.g., STM32 OCTOSPI), achieves near-XIP performance for boot code execution.
