Product details
Overview
S25FL032P0XNFA010 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 sub-sectors, 256-byte page size, and Quad I/O FAST_READ support up to 80 MHz (40 MB/s). It features OTP space (16 bytes + 490 bytes), JEDEC-compliant Device ID, and CFI compliance for host auto-configuration. Used in firmware storage for industrial microcontrollers and boot code retention in embedded systems.
For engineers reviewing the S25FL032P0XNFA010 datasheet, S25FL032P0XNFA010 pinout, S25FL032P0XNFA010 application, or S25FL032P0XNFA010 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O read bandwidth, W#/ACC-accelerated programming, OTP security capability, and industrial temperature range (–40°C to +85°C) operation.
Technical Context
The S25FL032P0XNFA010 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. Its memory array is organized into 64 uniform 64-KB sectors, with top/bottom parameter blocks subdivided into thirty-two 4-KB sub-sectors for fine-grained erase control.
It uses Cypress's 0.09 µm MirrorBit® process and integrates on-chip voltage regulation for program/erase operations, eliminating external high-voltage generation. Memory protection is enforced via Status Register BP2–BP0 bits and hardware W#/ACC pin logic, while OTP regions support factory or field-programmable secure identification with lockability.

| 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 mode; becomes bidirectional I/O in Dual/Quad I/O modes for parallelized reads/writes |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Hardware write lock when low; enables accelerated programming when driven to 9 V; serves as I/O2 in Quad modes |
| SI/IO0 | Serial Input / I/O0 | Command/address/data input in standard mode; bidirectional I/O0 in Dual/Quad modes |
| SCK | Serial Clock | Edge-triggered timing source: latches SI on rising edge, outputs SO on falling edge |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing SPI transaction without CS# toggle; acts as I/O3 in Quad I/O and QPP modes |
| VCC | Power Supply | 2.7–3.6 V input; powers internal charge pumps for program/erase; no external HV required |
| GND | Ground | Reference for all I/O and internal logic; must be tied to exposed pad if used for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s read throughput using SI, SO, W#/ACC, and HOLD# as simultaneous data lines - reduces boot time by >2× vs. standard SPI |
| Sub-sector Erase (P4E) | 4-KB erase blocks allow firmware parameter updates without disturbing adjacent application code - critical for OTA-safe field updates |
| W#/ACC Pin Acceleration | Applying 9 V to W#/ACC reduces page program time to ≤1.5 ms (typical) - improves manufacturing flash programming efficiency |
| CFI Compliance | Allows host system to auto-detect device geometry, timing, and command set - eliminates hard-coded flash drivers in bootloader design |
| OTP Locking Capability | 16-byte secure ID region can be permanently locked post-programming - prevents tampering with device identity or cryptographic keys |

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 |
|---|---|---|---|
| S25FL064L0XMFI001 | 64-Mbit density, same 2.7–3.6 V supply, 133-MHz Quad I/O read, 0.065 µm process, enhanced ECC | Higher capacity and faster read speed; supports larger firmware images and real-time data logging buffers | Select when new designs require ≥64 Mbit or need extended lifecycle support (S25FL064L remains active) |
| MX25L3233FZNI-10G | 32-Mbit, 2.7–3.6 V, 104-MHz FAST_READ, no Quad I/O, no OTP, different status register layout | Lacks QIOR/QPP and OTP; simpler command set but no sub-sector erase or accelerated programming | Choose for cost-sensitive legacy-compatible designs where Quad performance and secure ID are not required |
Compared with S25FL032P0XNFA010, the S25FL064L offers higher density and active long-term support, while the MX25L3233F provides basic SPI Flash functionality at lower cost-but sacrifices Quad I/O bandwidth, OTP security, and fine-grained erase control essential for modern firmware update architectures.

However, it remains supported for existing production and legacy BOM continuity with full documentation, lifecycle management, and traceable sourcing through Aetrix Electronics.
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 driven to 9 V for faster page programming (≤1.5 ms), and (3) I/O2 in Quad I/O and Quad Page Program modes. Its multi-functionality eliminates need for external acceleration circuitry.
Does S25FL032P0XNFA010 support execute-in-place (XIP)?
Yes. The device supports XIP via its high-speed Quad I/O read modes (QIOR), delivering up to 40 MB/s effective bandwidth-sufficient for direct execution of code from flash in microcontrollers with appropriate cache and prefetch logic, reducing RAM footprint requirements.
How is the OTP area secured against unauthorized access?
The 16-byte secure OTP region can be permanently locked using the LOCK command after programming. Once locked, OTP contents cannot be read or rewritten-even via debug interfaces-ensuring cryptographic keys or device IDs remain confidential and tamper-proof throughout the product lifecycle.
