Product details
Overview
S25FL032P0XMFA000 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 JEDEC-standard Device ID, 100,000 program/erase cycles per sector, 20-year data retention, and factory- or customer-programmable 16-byte OTP area for secure identification. Used in embedded boot code storage and firmware update storage in industrial controllers.
For engineers reviewing the S25FL032P0XMFA000 datasheet, S25FL032P0XMFA000 pinout, S25FL032P0XMFA000 application, or S25FL032P0XMFA000 equivalent, key selection considerations include SPI interface mode compatibility (Standard/Dual/Quad I/O), sub-sector erase granularity (4-KB/8-KB), W#/ACC-accelerated programming, Deep Power-Down current (3 µA), and CFI compliance for host auto-detection.
Technical Context
The S25FL032P0XMFA000 implements a serial peripheral interface with five dedicated I/O pins (CS#, SCK, SI/IO0, SO/IO1, HOLD#/IO3, W#/ACC/IO2) supporting Standard, Dual Output, Quad Output, Dual I/O, and Quad I/O read modes. Its internal architecture uses 0.09 µm MirrorBit® process technology and includes a status register with BP2–BP0 block protection bits and a configuration register for enhanced memory security.
It supports accelerated programming via 9-V signal on W#/ACC pin, Quad Page Programming at up to 80 MHz clock rate, and three erase granularities: bulk, 64-KB sector (SE), and 4-KB/8-KB sub-sectors (P4E/P8E). The device integrates a 128-bit (16-byte) factory- or field-programmable OTP area with lock capability and complies with Common Flash Interface (CFI) for host system interoperability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MB), organized as 64 × 64-KB sectors |
| Supply Voltage | 2.7 V to 3.6 V - enables direct integration into 3.0-V system rails without level-shifting |
| Read Speed | QUAD I/O FAST_READ: 80 MHz clock / 40 MB/s effective - doubles throughput vs. standard SPI |
| Erase Granularity | 4-KB sub-sector (P4E), 8-KB sub-sector (P8E), 64-KB sector (SE), and bulk - enables fine-grained firmware patching |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20 years data retention - suitable for field-upgradable embedded systems |
| Power Modes | Deep Power-Down: 3 µA typical; Standby: 80 µA typical - extends battery life in low-duty-cycle applications |
| OTP Area | 16 bytes (128-bit) one-time programmable space - supports secure device serialization or calibration data locking |
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; must fall before command latching; places device in active power mode when low |
| SCK | Serial Clock | Provides timing; commands/addresses/data latched on rising edge; SO output triggered on falling edge |
| SI/IO0 | Serial Input / I/O0 | Input for commands/addresses/data (rising edge); becomes output in Dual/Quad I/O modes |
| SO/IO1 | Serial Output / I/O1 | Output for read data (falling edge); becomes input in Dual/Quad I/O modes |
| W#/ACC/IO2 | Write Protect / Accelerate / I/O2 | Low = write protection; 9-V = accelerated programming; becomes output in Quad I/O mode |
| HOLD#/IO3 | Hold / I/O3 | Pauses communication without deselecting; low + CS# low = hold state; becomes output in Quad I/O mode |
| VCC | Power Supply | 2.7–3.6 V supply; powers all internal logic and charge pumps for program/erase |
| GND | Ground | Reference for all signals and internal voltage regulation |
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 bidirectional data lines |
| Sub-sector Erase (P4E/P8E) | Allows selective 4-KB or 8-KB erasure - critical for over-the-air firmware delta updates |
| W#/ACC Pin Acceleration | Applies 9-V to enable faster page programming - reduces write latency without external HV circuitry |
| CFI Compliance | Permits host systems to auto-detect device geometry and command set - simplifies bootloader portability |
| OTP Lock Capability | Once locked, 16-byte OTP region prevents further writes - ensures immutable device identity or calibration constants |
Applications
| Industrial PLC Firmware Storage | Medical Device Boot Code |
|---|---|

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; newer 65-nm process; supports octal DTR mode; no W#/ACC acceleration pin | Higher capacity required for larger firmware images; lacks legacy 9-V acceleration path | Select when migrating to higher-density, lower-power designs with modern controller support |
| MX25L3233F | 32-Mbit; 3.3-V only (no 2.7-V min); no OTP area; supports Dual/Quad I/O but no Quad Page Program | Lower cost; no secure identity provisioning; reduced programming flexibility | Select for cost-sensitive consumer applications where OTP and accelerated programming are unnecessary |
Compared with S25FL032P0XMFA000, S25FL064L offers double capacity and modern octal support but removes W#/ACC acceleration, while MX25L3233F provides basic Quad I/O at lower cost but omits OTP and sub-sector erase flexibility - making S25FL032P0XMFA000 uniquely suited for secure, field-upgradable industrial firmware with legacy timing constraints.

FAQ
Is S25FL032P0XMFA000 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migration to S25FL064L. However, it remains actively supported for existing production and legacy design refreshes with documented lifecycle continuity planning through Aetrix Electronics.
What package type does S25FL032P0XMFA000 use?
S25FL032P0XMFA000 uses an 8-pin SOIC package with 208-mil body width (SO8 wide), RoHS-compliant, lead-free, and rated for industrial temperature range (–40°C to +85°C), as confirmed by ordering code suffix "MFA".
Does this device support Quad Page Programming?
Yes. The S25FL032P0XMFA000 supports Quad Page Programming (QPP) using SI, SO, W#/ACC, and HOLD# as input pins at up to 80 MHz clock rate, enabling faster write throughput than standard Page Program mode.
Can the OTP area be reprogrammed after locking?
No. Once the 16-byte OTP region is locked via the OTP_LOCK instruction, it becomes permanently read-only. Programming and locking can be performed either at the factory or by the end customer prior to final system deployment.
