Product details
Overview
S25FL032P0XMFI003 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 FAST_READ at 80 MHz (40 MB/s). It supports accelerated programming via W#/ACC pin and includes 16-byte factory- or customer-programmable OTP for secure identification. Used in embedded boot code storage and firmware update storage in industrial controllers.
For engineers reviewing the S25FL032P0XMFI003 datasheet, S25FL032P0XMFI003 pinout, S25FL032P0XMFI003 application, or S25FL032P0XMFI003 equivalent, key selection considerations include sector/sub-sector erase granularity, Quad I/O throughput, OTP programmability, JEDEC CFI compliance, and industrial temperature range (–40°C to +85°C) support.
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 operating up to 80 MHz clock rate. It uses Cypress's 0.09 µm MirrorBit® process and integrates on-die voltage regulation for program/erase operations without external high-voltage supply-except when enabling accelerated programming via 9-V on W#/ACC.
Memory protection is implemented through Status Register Block Protection bits (BP2–BP0), W#/ACC pin assertion, and hardware-enabled deep power-down mode (3 µA typical). The device provides two JEDEC-compliant ID mechanisms: two-byte electronic signature and one-byte RES command response, ensuring host system compatibility across legacy and modern flash-aware bootloaders.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB), organized as 64 × 64-KB sectors with top/bottom 64-KB parameter blocks subdivided into 4-KB or 8-KB sub-sectors |
| Supply Voltage | 2.7 V to 3.6 V single supply; internally generates required voltages for program/erase-no external VPP needed except for accelerated mode |
| Read Throughput | QUAD I/O FAST_READ delivers 40 MB/s effective data rate at 80 MHz clock, doubling dual-I/O performance |
| Programming Speed | Page Program (1–256 bytes) completes in 1.5 ms typical; Quad Page Program enables parallel input via SI, SO, W#/ACC, HOLD# pins |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L | 64-Mbit density, same 2.7–3.6 V supply, enhanced Quad I/O timing, improved deep power-down (1 µA), newer 45 nm process | Direct migration path recommended by Cypress for new designs; supports larger firmware images and longer product roadmap | Select when designing new systems requiring >32 Mbit capacity or extended lifecycle support beyond S25FL032P end-of-life |
| MX25L3233F | 32-Mbit SPI Flash, 2.7–3.6 V, 104 MHz max clock, no Quad Page Program, no OTP, 10K-cycle endurance | Lacks sub-sector erase granularity and secure OTP; suitable only for cost-sensitive, non-security-critical applications | Consider only if OTP, CFI, or 100K-cycle endurance are not required-and if legacy board layout matches 8-pin SO pinout |
Compared with S25FL032P0XMFI003, S25FL064L offers double density and longer-term availability, while MX25L3233F trades security and endurance for lower unit cost-making the former ideal for forward-looking designs and the latter acceptable only in constrained-cost, low-security contexts.

FAQ
Is S25FL032P0XMFI003 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. While S25FL032P0XMFI003 remains available for legacy support and last-time buys, new projects should use S25FL064L for extended longevity, higher density, and updated process technology.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin serves three roles: (1) write protection when pulled low, (2) acceleration control-applying 9 V enables faster programming, and (3) I/O2 in Quad I/O and Quad Page Program modes. Its dual functionality requires careful PCB routing to avoid noise coupling during high-voltage acceleration pulses.
Does S25FL032P0XMFI003 support Dual/Quad I/O on all package variants?
Yes. All package options-including 8-pin SO, 16-pin SO, USON, WSON, and both 24-ball BGA configurations-support Dual and Quad I/O modes. Pin assignments for IO0–IO3 are consistent across packages, with HOLD# and W#/ACC repurposed as IO3 and IO2 respectively in Quad modes.
How is the OTP area secured against unauthorized writes?
The 16-byte OTP region can be permanently locked using the Write Status Register (WRR) command to set the OTP lock bit. Once locked, no further writes or erases are possible-even with W#/ACC asserted or VCC at maximum rating. Unlocking is impossible; the lock is irreversible and hardware-enforced.
