Product details
Overview
S25FL032P0XMFA003 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 read speeds up to 40 MB/s. It supports accelerated programming via W#/ACC pin, OTP area (16 bytes + 490 bytes), and CFI compliance for host system auto-configuration in embedded boot code storage.
For engineers reviewing the S25FL032P0XMFA003 datasheet, S25FL032P0XMFA003 pinout, S25FL032P0XMFA003 application, or S25FL032P0XMFA003 equivalent, key selection criteria include sector/sub-sector erase granularity, 100,000-cycle endurance, 20-year data retention, Deep Power-Down (3 µA), and compatibility with legacy S25FL032A designs.
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 High Performance Read (DIOR), Quad I/O High Performance Read (QIOR), and Quad Page Program (QPP). All high-speed modes operate at up to 80 MHz clock rate with corresponding effective data rates.
Memory organization comprises 64 × 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 uses Status Register BP2–BP0 bits and W#/ACC pin coupling, while OTP space supports secure device identification and customer-defined configuration storage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB) - sufficient for firmware images, boot code, and configuration tables in resource-constrained microcontrollers. |
| Supply Voltage | 2.7 V to 3.6 V - single-rail operation compatible with 3.3-V logic systems without level-shifting. |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s - enables fast code execution from XIP (execute-in-place) configurations. |
| Page Program Time | 1.5 ms typical (256 bytes) - reduces firmware update latency in field-programmable applications. |
| Erase Granularity | 64-KB sector, 4-KB sub-sector, 8-KB sub-sector - allows precise firmware patching without full bulk erase. |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20 years data retention - meets industrial lifecycle requirements. |
| Power Modes | Standby: 80 µA; Deep Power-Down: 3 µA - critical for battery-backed or energy-harvesting systems. |
Pinout & Package
Package: 8-pin SOIC (208-mil body width), RoHS-compliant, lead-free, industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | 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 mode; bidirectional in Dual/Quad I/O modes for high-speed reads. |
| W#/ACC/IO2 | Write Protect / Acceleration Control / I/O2 | Enables accelerated programming when driven high; provides write protection and serves as I/O2 in Quad modes. |
| GND | Ground Reference | Signal and power return path; must be low-impedance to ensure stable read/write margins. |
| SI/IO0 | Serial Input / I/O0 | Command/address/data input in standard mode; bidirectional in Dual/Quad I/O modes. |
| SCK | Serial Clock | Edge-triggered timing source; rising edge latches inputs, falling edge triggers outputs. |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing transfers without chip deselect; functions as I/O3 in Quad I/O and QPP modes. |
| VCC | Supply Voltage | Single 2.7–3.6 V rail powers all operations; internal charge pumps generate programming voltages. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Delivers 40 MB/s effective bandwidth using SI, SO, W#/ACC, and HOLD# pins-enables real-time firmware streaming. |
| Sub-sector Erase (P4E/P8E) | Supports 4-KB and 8-KB erase blocks-minimizes disruption during over-the-air updates in connected devices. |
| One-Time Programmable (OTP) Area | 16-byte secure ID + 490-byte user space-supports cryptographic key binding and immutable device serialization. |
| Common Flash Interface (CFI) Compliance | Allows automatic detection and configuration by host bootloader-eliminates hard-coded flash parameters in firmware. |
| Accelerated Programming Mode | Enabled via 9-V signal on W#/ACC pin-reduces page program time by >30% in production programming environments. |

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, 1.8-V/3.0-V dual supply, 133-MHz max clock, newer 45-nm process | Higher capacity and lower voltage support; not backward-pin-compatible with S25FL032P 8-pin SO package | Select for new designs requiring >32 Mbit or 1.8-V operation; migration requires PCB and firmware rework. |
| S25FL132K | 32-Mbit, 1.8-V/3.0-V dual supply, 104-MHz max clock, no OTP area, no sub-sector erase | Lacks 4-KB/8-KB erase granularity and secure OTP; supports only sector/bulk erase | Choose when cost optimization outweighs sub-sector flexibility and secure ID needs; verify bootloader compatibility with missing CFI fields. |
Compared with S25FL032P0XMFA003, S25FL064L offers double capacity and lower voltage support but requires hardware redesign, while S25FL132K sacrifices sub-sector erase and OTP for cost reduction-neither replicates the exact balance of legacy compatibility, granular erase, and secure provisioning.

FAQ
Is S25FL032P0XMFA003 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. However, it remains available for legacy design support, repair, and continuity programs where functional equivalence and existing qualification are required.
What package type does S25FL032P0XMFA003 use?
S25FL032P0XMFA003 uses an 8-pin SOIC package (208-mil body width), designated by the "M" in the part number and confirmed in Cypress ordering information as model "01" for SO/USON variants.
Does this device support Quad SPI mode without external level shifters?
Yes. The device natively supports Quad I/O modes (QIOR, QOR, QPP) using SI, SO, W#/ACC, and HOLD# pins-all operating within the 2.7–3.6 V supply range, eliminating need for external voltage translation in 3.3-V systems.
Can the OTP area be reprogrammed after locking?
No. Once the OTP region is locked via the Write Status Register command, it becomes permanently read-only. Programming and locking can be performed either at factory or by the customer, but lock operation is irreversible and verified by Status Register bit OTPLOCK.
