Product details
Overview
S25FL064P0XMFI003 from Cypress Semiconductor is a 64-Mbit, 3.0 V SPI flash memory with uniform 64-kB sectors, 4-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 W#/ACC pin at 9 V, OTP area (16 bytes + 490 bytes), and operates across –40°C to +85°C in industrial-grade 16-pin SOIC (300-mil) package. Used for firmware storage in embedded controllers requiring fast read access and secure identification.
For engineers reviewing the S25FL064P0XMFI003 datasheet, S25FL064P0XMFI003 pinout, S25FL064P0XMFI003 application, or S25FL064P0XMFI003 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O timing compliance, OTP programmability, and industrial temperature support - all confirmed in Cypress Document 002-00649 Rev. *J.
Technical Context
The S25FL064P implements a serial peripheral interface with five extended commands enabling Dual/Quad Output and Dual/Quad I/O read modes, plus Quad Page Programming. Its architecture uses 90-nm MirrorBit® technology, delivering 100,000 program/erase cycles per sector and 20-year data retention.
Memory protection relies on Status Register BP2–BP0 bits and hardware W#/ACC pin control. The device supports CFI compliance for host auto-detection and integrates dedicated OTP space for factory- or customer-programmed secure IDs - accessible via OTPP/OTPR instructions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 MB), organized as 128 × 64-kB sectors with top/bottom 64-kB parameter blocks split into thirty-two 4-kB sub-sectors. |
| Supply Voltage | 2.7 V to 3.6 V single supply - enables direct integration with 3.3 V logic without level-shifting or auxiliary regulators. |
| Read Speed | QUAD I/O FAST_READ at 80 MHz clock → 40 MB/s effective throughput - reduces boot time in microcontroller-based systems. |
| Page Program Time | 1.5 ms typical for up to 256 bytes - supports rapid field firmware updates without long blocking delays. |
| Erase Granularity | Sub-sector (4-kB) and sector (64-kB) erase commands (20h/40h/D8h) - allows precise firmware patching without bulk rewrites. |
| OTP Capacity | 16 bytes (128-bit) factory/cust-programmable ID + 490 bytes additional OTP - enables unique device binding and secure boot key storage. |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20 years data retention - validated for long-life industrial deployments. |
Pinout & Package
Package: 16-pin SOIC (300-mil body width), RoHS-compliant, lead-free, industrial temperature grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable signal; must fall before command latching; places device in active power mode when low. |
| SCK | Serial Clock | Input timing reference; rising edge latches SI data, falling edge triggers SO output - defines SPI timing domain. |
| SI/IO0 | Serial Input / I/O0 | Primary data input in standard mode; becomes bidirectional I/O0 in Dual/Quad I/O modes - enables high-speed parallelized transfers. |
| SO/IO1 | Serial Output / I/O1 | Primary data output in standard mode; becomes bidirectional I/O1 in Dual/Quad I/O modes - doubles/quadruples read bandwidth. |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Hardware write lock (low = protect); 9 V input enables accelerated programming; serves as I/O2 in Quad modes. |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing SPI transaction without deselecting CS#; functions as I/O3 in Quad I/O - preserves bus state during interrupts. |
| VCC | Power Supply | 2.7–3.6 V input; powers internal charge pumps for erase/program - eliminates need for external high-voltage generators. |
| GND | Ground | Reference return path for all signals and internal circuitry - critical for noise immunity in mixed-signal embedded systems. |
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 - cuts boot latency by >50% vs. standard SPI. |
| Uniform Sector + Sub-Sector Architecture | Supports fine-grained 4-kB firmware patches via P4E command - avoids full 64-kB sector erases during over-the-air updates. |
| One-Time Programmable (OTP) Area | 16-byte secure ID region + 490-byte general-purpose OTP - allows immutable device serialization and cryptographic key injection pre-deployment. |
| Accelerated Programming Mode | 9 V applied to W#/ACC pin reduces page program time by ~40% - improves manufacturing flash programming throughput. |
| CFI Compliance | Enables automatic detection and configuration by host bootloader - eliminates hard-coded flash parameters in system firmware. |
Applications
| Industrial PLC Firmware Storage | Medical Device Boot Image Storage |
|---|---|
|
Use Scenario: Storing firmware and calibration tables in programmable logic controllers deployed in factory automation environments. IC Role / Device Role / Timing Role: Non-volatile boot memory providing deterministic read latency and sector-level update capability.

IC Role / Device Role / Timing Role: Field-updatable configuration store with hardware write protection to prevent accidental corruption. Use Value: W#/ACC pin + BP2–BP0 status register bits enforce hardware-level lock on critical config sectors - eliminating software-only vulnerabilities. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XMFI003 | Successor device with identical pinout, enhanced 133 MHz Quad I/O speed, and improved 200K-cycle endurance. | Same industrial temperature range and SOIC package; supports backward-compatible command set but adds new features like octal DTR mode. | Select for new designs requiring longer lifecycle support and higher performance headroom - Cypress officially recommends migration. |
| MX25L6433FZNI-10G | 64-Mbit SPI flash from Macronix; 104 MHz max clock, no Quad Page Programming, no OTP area, 100K-cycle endurance. | Lacks OTP security features and accelerated programming; requires different command set for sub-sector erase (no P4E/P8E). | Acceptable where cost sensitivity outweighs secure ID needs and firmware update flexibility - verify command compatibility in existing firmware. |
Compared with S25FL064P0XMFI003, the S25FL064L0XMFI003 offers higher speed and longer endurance while maintaining pin and command compatibility, whereas MX25L6433FZNI-10G provides cost-effective drop-in replacement only where OTP and Quad Page Programming are unused.

FAQ
Is S25FL064P0XMFI003 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Designs" and designates S25FL064L0XMFI003 as the factory-recommended migration path. While S25FL064P0XMFI003 remains available for legacy production and repair, new projects should adopt the L-series for extended support, higher performance, and updated qualification.
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 9 V is applied for faster page programming, and (3) I/O2 in Quad I/O and Quad Page Programming modes. Its dual functionality eliminates need for separate acceleration control lines in PCB layout.
How does the OTP area differ from standard flash memory?
The OTP area consists of two physically distinct regions: 16 bytes (128-bit) for permanent, secure device identification (factory- or customer-programmable and lockable), and 490 bytes for general-purpose one-time use. Unlike main array flash, OTP cells cannot be erased after programming - ensuring irreversible binding of keys or IDs.
Can S25FL064P0XMFI003 operate with standard SPI controllers without Quad I/O support?
Yes. It fully supports standard SPI mode (single I/O) with READ (03h) and FAST_READ (0Bh) commands at up to 40 MHz and 104 MHz respectively. All advanced modes (Dual/Quad I/O, Quad Page Program) are optional extensions - basic functionality remains compatible with legacy SPI masters lacking multi-I/O capability.
