Product details
Overview
S25FL064P0XNFI003 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 operates across 2.7–3.6 V, supports accelerated programming via W#/ACC pin, and includes 128-bit factory- or customer-programmable OTP for secure identification. Used in embedded boot code storage and firmware update storage.
For engineers reviewing the S25FL064P0XNFI003 datasheet, S25FL064P0XNFI003 pinout, S25FL064P0XNFI003 application, or S25FL064P0XNFI003 equivalent, key selection criteria include sector/sub-sector erase granularity, Quad I/O read performance, OTP programmability, W#/ACC-accelerated write timing, and industrial temperature range (–40°C to +85°C) compliance.
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 - all using SI, SO, W#/ACC, and HOLD# as bidirectional I/O pins. Its architecture features two configurable parameter blocks (top/bottom), each subdivided into thirty-two 4-kB sub-sectors.
Internally generated high-voltage programming is enabled only when W#/ACC is driven to 9 V; otherwise, standard 3.0 V operation suffices for reads and non-accelerated writes. The device complies with JEDEC-standard two-byte ID and CFI, ensuring host system interoperability across multiple flash vendors.
Key Specifications

| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Low = hardware write protection; 9 V = enable accelerated programming; I/O in Quad modes |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing SPI transfer without deselecting chip; I/O in Quad I/O and QPP modes |
| VCC | Power Supply | 2.7–3.6 V main supply; powers internal charge pumps for programming/erase |
| GND | Ground | Reference for all I/O and internal circuitry; connects to exposed thermal pad (optional) |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Enables 40 MB/s read bandwidth using four pins simultaneously, reducing boot latency in resource-constrained systems |
| Configurable Sub-Sector Erase (P4E/P8E) | Allows selective 4-kB or 8-kB erases for fine-grained firmware patching without disturbing adjacent code |
| W#/ACC Pin Accelerated Programming | Reduces page program time below 1.5 ms when 9 V applied, improving field firmware update speed |
| 128-bit Secure OTP Area | Factory- or user-lockable space for immutable device identity, cryptographic keys, or calibration data |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XNFI003 | Successor device; same density, package, and pinout; improved 133 MHz FAST_READ, lower deep power-down current (1 μA) | Recommended for new designs; supports identical industrial temp grade and WSON8 footprint | Select for new projects requiring extended lifecycle support and higher read bandwidth |
| MX25L6433FZNI-10G | 64 Mbit SPI flash; 104 MHz max clock; no W#/ACC acceleration; 1.8/3.3 V dual supply option | Lacks OTP and Quad Page Programming; supports wider voltage range but no accelerated write mode | Choose where cost sensitivity outweighs need for secure ID or fast field updates |
Compared with S25FL064P0XNFI003, the S25FL064L offers higher read speed and longer manufacturer support, while MX25L6433F provides broader voltage flexibility at the expense of OTP security and accelerated programming capability.

FAQ
Is S25FL064P0XNFI003 still recommended for new designs?
No. Cypress explicitly states this part is retired and not recommended for new designs. The S25FL064L is the factory-recommended migration path, offering identical pinout, enhanced performance, and ongoing support. Customers initiating new projects should select S25FL064L0XNFI003 or later revisions.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin serves three roles: hardware write protection when pulled low, acceleration trigger when driven to 9 V (enabling faster page programming), and I/O2 in Quad I/O and Quad Page Programming modes. Its multi-functionality eliminates need for external acceleration circuitry.
Can the OTP area be reprogrammed after locking?
No. Once the 128-bit secure OTP region is locked via the appropriate command sequence, it becomes permanently read-only. The lock is irreversible and enforced by on-die fuse logic. General-purpose OTP (490 B) may be programmed once per location but lacks hardware lock capability.
Does S25FL064P0XNFI003 support Dual I/O mode on all packages?
Yes. Dual I/O mode (DIOR) is supported across all package variants - SO16, WSON8, and both 24-ball BGA configurations - because it relies solely on SI/IO0 and SO/IO1 signal routing, which are present and functionally identical in every package type per the connection diagrams.
