Product details
Overview
S25FL032P0XMFI0109 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 9-V W#/ACC pin and includes 16-byte factory- or user-programmable OTP for secure identification. Used in boot code storage for industrial microcontrollers and FPGA configuration.
For engineers reviewing the S25FL032P0XMFI0109 datasheet, S25FL032P0XMFI0109 pinout, S25FL032P0XMFI0109 application, or S25FL032P0XMFI0109 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O read bandwidth, OTP programmability, and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
The S25FL032P implements SPI-compatible command set including standard READ, FAST_READ, DOR, QOR, DIOR, QIOR, and QUAD Page Program (QPP), enabling flexible interface modes without external logic. Its dual- and quad-I/O operations use SI/IO0, SO/IO1, W#/ACC/IO2, and HOLD#/IO3 as bidirectional data lines under clock control.
Memory protection relies on Status Register BP2–BP0 bits and hardware W#/ACC pin assertion, while erase flexibility includes bulk, 64-KB sector (SE), 4-KB sub-sector (P4E), and 8-KB sub-sector (P8E) commands. Internal charge pumps generate required high-voltage programming pulses from 3.0-V supply alone.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s read bandwidth using four pins simultaneously - reduces boot time vs. standard SPI |
| Sub-sector erase (P4E/P8E) | Allows updating 4-KB or 8-KB firmware segments without erasing full 64-KB sector - preserves adjacent code |
| One-Time Programmable (OTP) area | 16-byte secure ID region programmable once by customer or factory - supports device authentication |
| Accelerated programming mode | 9-V signal on W#/ACC pin cuts page program time to 1.5 ms typical - improves production programming speed |
| Common Flash Interface (CFI) | Standardized query table allows host system to auto-detect geometry and command set - simplifies driver porting |

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 |
|---|---|---|---|
| S25FL064L0XMFI010 | 64-Mbit density, same 2.7–3.6 V supply, identical pinout and command set; supports higher clock rates up to 133 MHz in QIOR mode | Required where larger firmware images exceed 32-Mbit capacity; backward compatible but not drop-in due to density mismatch in address decoding | Select when future firmware growth headroom or higher read bandwidth (>40 MB/s) is needed; migration path officially endorsed by Cypress |
| MX25L3233FZBI-10G | 32-Mbit density, 2.7–3.6 V supply, supports Quad I/O but lacks P4E/P8E sub-sector erase; OTP area limited to 1024 bits (128 bytes) but no factory lock option | Acceptable for static firmware storage without field updates; unsuitable for incremental patching due to absence of 4-KB erase capability | Choose only if sub-sector erase is unnecessary and cost sensitivity outweighs long-term field update flexibility |
Compared with S25FL032P0XMFI0109, S25FL064L0XMFI010 offers scalable density and faster QIOR, while MX25L3233FZBI-10G trades erase granularity for broader vendor availability - making the original optimal for field-upgradable industrial designs requiring precise 4-KB update boundaries.

FAQ
Is S25FL032P0XMFI0109 still in production?
No - Cypress retired the S25FL032P family in 2017 and recommends S25FL064L for new designs. However, Aetrix Electronics maintains legacy inventory with full traceability and provides last-time-buy support, including full datasheet documentation and application guidance for existing designs.
What package type does S25FL032P0XMFI0109 use?
S25FL032P0XMFI0109 uses an 8-pin SOIC package with 208-mil body width (SO8 wide), lead-free and halogen-free per ordering code "MFI", rated for industrial temperature range (–40°C to +85°C).
Does this device support Quad SPI mode without external level shifters?
Yes - S25FL032P0XMFI0109 natively supports Quad I/O modes (QIOR, QOR, QPP) using its four dedicated I/O pins (IO0–IO3) at 3.0 V levels. No external level shifting is required, and all timing complies with JEDEC-standard Quad SPI protocols.
Can the OTP area be reprogrammed after initial programming?
No - the 16-byte OTP region is one-time programmable and permanently locked after first write. Once programmed, bits can only be changed from '1' to '0', and the lock bit prevents further writes. This ensures cryptographic keys or device IDs remain immutable throughout product lifetime.
