Infineon Technologies S25FL064P0XMFB003

Overview

S25FL064P0XMFB003 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 support for Quad I/O FAST_READ at 80 MHz (40 MB/s). 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, firmware update partitions, and configuration memory for industrial controllers.

For engineers reviewing the S25FL064P0XMFB003 datasheet, S25FL064P0XMFB003 pinout, S25FL064P0XMFB003 application, or S25FL064P0XMFB003 equivalent, key selection criteria include SPI quad I/O timing compliance, OTP area availability (16 bytes + 490 bytes), sector/sub-sector erase granularity, and W#/ACC-accelerated programming capability.

Technical Context

The S25FL064P implements a 90-nm MirrorBit® NOR architecture with CFI-compliant command set and dual/quad I/O modes enabled via dedicated IO0–IO3 pins. It supports five high-performance read instructions-including QIOR and DIOR-each requiring specific pin reconfiguration and clock-synchronized sampling on rising/falling edges.

Internal voltage regulation enables single-supply 3.0 V operation for read, program, and erase; accelerated programming requires externally applied 9 V to W#/ACC. Memory protection uses Status Register BP2–BP0 bits combined with W#/ACC logic level, while OTP locking is irreversible after execution of LOCK_OTP command.

FAQ

Is S25FL064P0XMFB003 still recommended for new designs?

No. Cypress explicitly states this part is retired and not recommended for new designs. The S25FL064L0XMFB003 is the factory-recommended migration path, offering identical pinout, enhanced process node, and extended voltage support. Design reuse is possible only for legacy repair or continuity programs with documented lifecycle risk acceptance.

What does the '003' suffix indicate in S25FL064P0XMFB003?

The '003' suffix specifies the 24-ball BGA package with 6 × 4 pin configuration (per Cypress ordering guide). It distinguishes this variant from '002' (5 × 5 BGA), '00' (SO-16), and 'N' (WSON-8). Mechanical dimensions are 6 mm × 8 mm with 1.00 mm ball pitch, and the package is lead-free and low-halogen compliant.

How is the W#/ACC pin used for accelerated programming?

The W#/ACC pin must be driven to 9 V (±0.5 V) during Page Program or Quad Page Program commands to activate accelerated mode, reducing typical programming time to ≤1.5 ms per 256-byte page. This voltage is supplied externally - the device does not generate it internally. Standard 3.3 V operation remains valid but yields slower programming.

Can the OTP area be reprogrammed after locking?

No. Once the LOCK_OTP command is executed, the 16-byte secure OTP region becomes permanently read-only. The 490-byte general-purpose OTP region can be written once per byte but cannot be erased or rewritten. Neither region supports post-lock modification - design verification and secure key injection must occur before final locking.
