Product details
Overview
S25FL064P0XMFB000 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 for industrial microcontrollers requiring fast, secure, in-system programmable nonvolatile memory.
For engineers reviewing the S25FL064P0XMFB000 datasheet, S25FL064P0XMFB000 pinout, S25FL064P0XMFB000 application, or S25FL064P0XMFB000 equivalent, key selection criteria include SPI quad I/O timing compliance, OTP security area (16 B + 490 B), W#/ACC-accelerated programming, sector/sub-sector erase granularity, and industrial temperature grade (–40°C to +85°C).
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-leveraging SI, SO, W#/ACC, and HOLD# as bidirectional I/O pins. Its architecture includes two configurable 64-kB parameter blocks subdivided into sixteen 4-kB sub-sectors each.
It integrates JEDEC-standard Device ID, CFI compliance for host auto-configuration, and a factory- or customer-programmable OTP area (128-bit secure ID + 490-byte general use) accessed via OTPP/OTPR instructions. Internal charge pumps generate required programming voltages; no external high-voltage supply is needed except for W#/ACC pin during accelerated programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 MB); sufficient for full firmware images or dual-bank boot code in resource-constrained MCUs. |
| Supply Voltage | 2.7 V to 3.6 V single supply; eliminates need for auxiliary voltage rails in 3.3 V system designs. |
| Read Speed | QUAD I/O FAST_READ at 80 MHz clock → 40 MB/s effective throughput; enables rapid code execution from XIP configurations. |
| Erase Granularity | 64-kB sector, 4-kB sub-sector (P4E), and 8-kB sub-sector (P8E); allows fine-grained firmware updates without bulk erasure. |
| Endurance & Retention | 100,000 program/erase cycles per sector; 20-year data retention; validated for long-life industrial deployments. |
| OTP Area | 16-byte secure ID + 490-byte user space; supports device binding, calibration data, or cryptographic key storage. |
| Power Modes | Standby: 80 μA typical; Deep Power-Down: 3 μA typical; critical for battery-backed or energy-harvesting systems. |
Pinout & Package
Package: 24-ball BGA (6 × 8 mm), 6 × 4 pin configuration, lead-free, industrial temperature grade (–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 asserted. |
| SCK | Serial Clock | Drives all timing; commands/addresses latched on rising edge; SO output triggered on falling edge. |
| SI/IO0 | Serial Input / I/O0 | Input for commands/addresses/data in standard mode; becomes bidirectional I/O in Dual/Quad I/O and QPP modes. |
| SO/IO1 | Serial Output / I/O1 | Output for read data in standard mode; bidirectional in Dual/Quad I/O modes; high-Z when HOLD# active. |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Low = write protection; high-voltage pulse enables accelerated programming; functions as I/O2 in Quad modes. |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing SPI transfer without CS# deassertion; acts as I/O3 in Quad I/O and QPP modes. |
| VCC | Supply Voltage | 2.7–3.6 V input; powers internal logic and charge pumps for erase/program operations. |
| GND | Ground | Reference for all I/O and internal circuitry; must be low-impedance for stable timing and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O High Performance Read (QIOR) | Uses all four I/O pins (IO0–IO3) at 80 MHz for 40 MB/s throughput-enables efficient execute-in-place (XIP) from flash. |
| Sub-sector Erase (P4E/P8E) | Enables 4-kB or 8-kB erasure within top/bottom 64-kB parameter blocks-reduces update latency vs. full sector erase. |
| One-Time Programmable (OTP) Area | 16-byte secure ID + 490-byte user space, lockable per region-supports device authentication and field calibration persistence. |
| Accelerated Programming Mode | Applied via 9 V pulse on W#/ACC pin; reduces page program time to ≤1.5 ms (typical)-improves firmware update speed. |
| CFI Compliance | Allows host system to auto-detect device geometry, timing, and command set-simplifies driver portability across flash families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XMFB000 | Successor device; same density, package, and pinout; adds 133 MHz Quad I/O, enhanced security registers, and improved ECC. | Required for new designs per Cypress migration guidance; supports higher-speed XIP and secure boot chains. | Select for new projects needing extended lifecycle support and future-proof timing margins. |
| MX25L6433FZNI-10G | 64 Mbit SPI flash; 104 MHz max clock; no Quad Page Programming; OTP area limited to 128 bits only; no W#/ACC acceleration. | Lower-cost alternative where accelerated programming and extended OTP are not required. | Acceptable for cost-sensitive, low-update-frequency applications lacking advanced security needs. |
Compared with S25FL064P0XMFB000, the S25FL064L offers higher performance and extended support, while the MX25L6433F provides basic functionality at lower cost-but lacks sub-sector erase control, OTP flexibility, and W#/ACC acceleration critical for field-upgradable systems.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability nonvolatile memory and programmable system-on-chip solutions for industrial, automotive, and IoT applications.

FAQ
Is S25FL064P0XMFB000 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Designs" and designates S25FL064L as the factory-recommended migration path. The S25FL064P remains available for legacy production and repair, but lacks long-term roadmap support, updated security features, and newer timing specifications found in the L-series.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin serves three roles: (1) write protection when pulled low, (2) acceleration trigger when pulsed to 9 V to reduce page program time to ≤1.5 ms, and (3) I/O2 in Quad I/O and Quad Page Programming modes. Its dual-function design enables both security and performance optimization without additional pins.
Does S25FL064P0XMFB000 support execute-in-place (XIP) operation?
Yes. Its QUAD I/O FAST_READ mode delivers 40 MB/s effective throughput at 80 MHz, enabling direct code execution from flash in microcontrollers with SPI XIP capability. This eliminates need for RAM-based code loading and reduces boot time in resource-limited systems.
How is memory protection implemented on this device?
Protection uses Status Register Block Protection bits (BP2–BP0) combined with the W#/ACC pin state. BP bits define protected address ranges (entire array, top/bottom sectors, or parameter blocks), while W#/ACC must be high to allow writes/erases. This dual-layer scheme prevents accidental or malicious modification of critical firmware regions.
