Product details
Overview
S25FL032P0XNFB000 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 W#/ACC pin, 100,000 erase/write cycles per sector, and 20-year data retention. Used in embedded boot code storage for industrial microcontrollers requiring SPI-compatible nonvolatile memory.
For engineers reviewing the S25FL032P0XNFB000 datasheet, S25FL032P0XNFB000 pinout, S25FL032P0XNFB000 application, or S25FL032P0XNFB000 equivalent, key selection criteria include SPI quad I/O performance, OTP security area (16 bytes + 490 bytes), sub-sector erase granularity, JEDEC CFI compliance, and industrial temperature range (–40°C to +85°C).
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 high-speed modes operate at up to 80 MHz clock rate with corresponding effective data rates up to 40 MB/s.
It features a 0.09 µm MirrorBit® process, integrated charge pump for internal voltage generation during program/erase, and configurable memory protection using Status Register BP2–BP0 bits. The device includes dedicated OTP space (128-bit factory-lockable + 490-byte user-programmable) and supports Deep Power-Down mode (3 µA typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB); sufficient for firmware images and configuration data in resource-constrained MCU systems. |
| Supply Voltage | 2.7 V to 3.6 V; single-rail operation eliminates need for auxiliary voltage regulators in 3.0-V system designs. |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s effective; enables fast boot-time code execution from flash. |
| Erase Granularity | 4-KB sub-sector (P4E), 8-KB sub-sector (P8E), 64-KB sector (SE), and bulk erase; allows precise firmware update without full chip reprogramming. |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20 years data retention at +85°C; suitable for field-upgradable industrial control firmware. |
| OTP Area | 16-byte (128-bit) factory-lockable + 490-byte user-programmable OTP; provides secure device ID and calibration data storage. |
| Power Modes | Standby: 80 µA typical; Deep Power-Down: 3 µA typical; reduces idle power in battery-backed or energy-sensitive applications. |
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 read; bidirectional in Dual/Quad I/O modes for increased throughput. |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Enables accelerated programming when driven high (9 V); also functions as I/O2 in Quad modes. |
| GND | Ground Reference | Signal and power return; exposed thermal pad must be connected to GND plane with zero-voltage differential. |
| SI/IO0 | Serial Input / I/O0 | Command/address/data input in standard mode; bidirectional in Dual/Quad I/O for full-duplex operation. |
| SCK | Serial Clock Input | Edge-triggered timing source; rising edge latches input, falling edge triggers output. |
| HOLD#/IO3 | Hold Input / I/O3 | Pauses ongoing SPI transfer without deselecting chip; acts as I/O3 in Quad I/O and QPP modes. |
| VCC | Power Supply | 2.7–3.6 V supply; powers internal logic and charge pump for program/erase operations. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s effective bandwidth using SI, SO, W#/ACC, and HOLD# as data lines-doubles throughput vs. standard SPI. |
| Sub-sector Erase (4-KB & 8-KB) | Allows selective firmware patching without erasing entire 64-KB sectors-reduces update time and wear on adjacent code regions. |
| One-Time Programmable (OTP) Regions | Provides tamper-resistant storage for cryptographic keys or unique identifiers; 16-byte factory-lockable section prevents post-deployment modification. |
| Common Flash Interface (CFI) Compliance | Enables automatic detection and configuration by host bootloader-eliminates hard-coded flash parameters in embedded firmware. |
| Accelerated Programming Mode | Reduces page program time to ≤1.5 ms (typical) when 9 V applied to W#/ACC-improves in-system 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, identical pinout and command set, improved 133-MHz Quad I/O speed. | Direct migration path recommended by Cypress for new designs; supports larger firmware images without layout change. | Select when future-proofing for firmware growth or requiring higher read bandwidth; compatible with existing S25FL032P PCB footprints in WSON/BGA variants. |
| MX25L3233F | 32-Mbit, 2.7–3.6 V, supports DTR mode up to 80 MHz, but lacks OTP area and sub-sector erase commands (P4E/P8E). | Lower-cost alternative where secure ID and fine-grained erase are not required; no factory-lockable OTP. | Choose only if OTP and 4-KB erase are unnecessary; verify bootloader compatibility due to missing CFI and command set gaps. |
Compared with S25FL032P0XNFB000, S25FL064L offers double capacity and faster Quad I/O without footprint change, while MX25L3233F sacrifices OTP and sub-sector erase for cost-making it unsuitable for secure or field-upgradable designs.

FAQ
Is S25FL032P0XNFB000 still in production?
No-Cypress officially retired the S25FL032P family and recommends S25FL064L for new designs. However, Aetrix Electronics maintains legacy inventory with full traceability and supports existing production runs through lifecycle management services.
What package does S25FL032P0XNFB000 use?
S25FL032P0XNFB000 uses the 8-contact WSON package (6 × 8 mm), with an exposed thermal pad that must be connected to GND on the PCB using low-impedance routing to ensure thermal stability and signal integrity.
Does this device support Quad SPI mode?
Yes-it supports Quad I/O High Performance Read (QIOR) and Quad Page Program (QPP) using SI, SO, W#/ACC, and HOLD# pins simultaneously, achieving 80 MHz clock rate and 40 MB/s effective data rate.
Can the OTP area be reprogrammed after locking?
No-the 16-byte factory-lockable OTP region becomes permanently read-only once locked; the additional 490-byte OTP space can be programmed once and read multiple times, but cannot be erased or rewritten.
