Infineon Technologies S25FL064P0XMFA000

Overview

S25FL064P0XMFA000 from Cypress Semiconductor is a 64-Mbit, 3.0 V SPI flash memory with uniform 64-kB sectors, 256-byte page size, and support for Quad I/O FAST_READ at 80 MHz (40 MB/s effective data rate). It operates across 2.7–3.6 V, delivers 100,000 erase/program cycles per sector, and retains data for 20 years. Used in embedded boot code storage for industrial microcontrollers requiring fast, reliable nonvolatile memory.

For engineers reviewing the S25FL064P0XMFA000 datasheet, S25FL064P0XMFA000 pinout, S25FL064P0XMFA000 application, or S25FL064P0XMFA000 equivalent, key selection factors include its 90-nm MirrorBit® process, OTP area (16 bytes + 490 bytes), dual/quad I/O modes, W#/ACC-accelerated programming, and BGA/SO/WSON package compatibility.

Technical Context

The S25FL064P implements a serial peripheral interface with five extended commands enabling Dual Output Read, Quad Output Read, Dual I/O High Performance Read, Quad I/O High Performance Read, and Quad Page Programming - all using SI, SO, W#/ACC, and HOLD# as bidirectional I/O pins. Its architecture includes two configurable 64-kB parameter blocks subdivided into thirty-two 4-kB sub-sectors.

Internal voltage regulation enables single-supply 2.7–3.6 V operation for read, program, and erase. Accelerated programming requires 9 V applied to W#/ACC. Memory protection uses Status Register BP2–BP0 bits and hardware W#/ACC assertion, while CFI compliance allows host system auto-configuration.

FAQ

Is S25FL064P0XMFA000 still recommended for new designs?

No. Cypress explicitly states this part is retired and not recommended for new designs. The S25FL064L0XMFA000 is the factory-recommended migration path, offering higher speed (133 MHz), lower deep power-down current (1 μA), and continued production support. Designers should initiate migration planning immediately.

What package does S25FL064P0XMFA000 use?

S25FL064P0XMFA000 uses a 16-pin SOIC package with 300-mil body width, lead-free finish, and industrial temperature range (–40°C to +85°C). The "M" in the part number denotes SOIC; "N" would indicate WSON, and "B" a BGA variant.

Does this device support hardware write protection?

Yes. The W#/ACC pin functions as hardware write protect when driven low, working in conjunction with Status Register BP2–BP0 bits to lock specific memory regions. This prevents accidental program or erase operations during system operation or power transients.

Can the OTP area be programmed in-system?

Yes. The 16-byte secure OTP region and additional 490-byte user OTP space can be programmed in-system using the OTPP instruction. Once locked (via OTP lock bits), the secure region becomes permanently read-only - enabling device-specific key binding and tamper-resistant identification.
