Product details
Overview
S25FL128P0XMFI000 from Cypress Semiconductor is a 128-Mbit, 3.0 V serial NOR Flash memory with uniform 64 KB sector architecture, 104 MHz SPI interface, and 2.7–3.6 V single-supply operation. It supports Page Program (up to 256 bytes in 1.5 ms), 64 KB sector erase (0.5 s typical), and Deep Power Down mode (3 µA typical), targeting firmware storage in industrial microcontroller boot applications.
For engineers reviewing the S25FL128P0XMFI000 datasheet, S25FL128P0XMFI000 pinout, S25FL128P0XMFI000 application, or S25FL128P0XMFI000 equivalent, key selection criteria include sector granularity (64 KB vs. 256 KB), WP#/ACC-accelerated programming support, SOIC-16 vs. WSON-8 package compatibility, and migration path to S25FL128S.
Technical Context
The S25FL128P0XMFI000 implements a standard SPI bus interface compliant with CPOL=0/CPHA=0 and CPOL=1/CPHA=1 modes, using SI/SO for full-duplex serial data transfer synchronized to SCK. It integrates on-chip voltage regulation for internal program/erase operations, eliminating need for external high-voltage generators except when enabling Accelerated Programming via 8.5–9.5 V applied to WP#/ACC.
Memory organization consists of 256 uniform 64 KB sectors (total 128 Mbit), with non-volatile Block Protect bits (BP3–BP0) in the Status Register enabling software-configurable read-only protection. Erase commands include Sector Erase (20h/D8h) and Bulk Erase (60h/C7h), while Write Enable (06h) and Status Register polling (05h) govern command sequencing and operation completion detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: 16-pin SOIC (300-mil body width), industry-standard footprint compatible with legacy PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable signal; must fall before any command; places device in active power mode |
| SO | Serial Output | Drives data on falling edge of SCK; high-impedance when CS# high or HOLD# low |
| WP#/ACC | Write Protect / Accelerated Programming Input | Low = hardware write protection; 8.5–9.5 V = enables faster 1.2 ms page program |
| HOLD# | Hold Input | Pauses ongoing SPI transaction without deselecting device; requires CS# low to function |
| SI | Serial Input | Latches commands, addresses, and data on rising edge of SCK |
| SCK | Serial Clock Input | Provides timing; rising edge latches input, falling edge triggers output |
| VCC | Power Supply | 2.7–3.6 V single supply; powers all read, program, and erase functions |
| GND | Ground | Reference for all I/O and internal circuitry; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Uniform 64 KB Sector Architecture | Enables precise firmware partitioning and over-the-air update management without wasting erase space |
| Accelerated Programming Mode | Reduces page program time from 1.5 ms to 1.2 ms using external 8.5–9.5 V on WP#/ACC pin |
| Deep Power Down Mode | 3 µA typical current draw - extends battery life in always-on edge sensor nodes during idle periods |
| Hardware + Software Memory Protection | Combines WP#/ACC pin control with BP3–BP0 status register bits for layered security against accidental writes |
| Standard SPI Interface (Mode 0/3) | Ensures interoperability with ARM Cortex-M, Renesas RX, and NXP Kinetis microcontrollers without custom drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL128S0XMFI000 | Successor device with enhanced 133 MHz clock, 1.2 V I/O compatibility, and improved ECC support | Required for new designs; supports higher-speed boot from modern MCUs with dual/quad SPI | Select when designing new platforms requiring extended lifecycle support and future-proof interface scalability |
| MX25L12833FZNI-10G | 104 MHz, 128 Mbit, 64 KB sectors; no WP#/ACC acceleration; different status register layout and command set | Drop-in replacement only for basic read/program/erase functions; not compatible for accelerated programming or identical protection schemes | Choose for cost-sensitive legacy redesigns where WP#/ACC functionality and Cypress-specific protection features are unused |
Compared with S25FL128P0XMFI000, the S25FL128S offers higher speed and broader voltage tolerance but requires firmware driver updates, while the MX25L12833F provides functional equivalence for basic SPI Flash use cases without accelerated programming or Cypress-specific protection logic.

FAQ
Is S25FL128P0XMFI000 still recommended for new designs?
No. Cypress explicitly states this part is not recommended for new or current designs. The S25FL128S is the factory-recommended migration path, offering higher clock speed (133 MHz), 1.2 V I/O compatibility, and updated ECC capabilities. Designers should transition to S25FL128S for all new projects to ensure long-term supply and technical support.
What is the function of the WP#/ACC pin beyond write protection?
The WP#/ACC pin serves dual roles: when held low, it enables hardware-based memory protection aligned with Status Register BP bits; when supplied with 8.5–9.5 V, it activates Accelerated Programming mode, reducing typical page program time from 1.5 ms to 1.2 ms. This voltage must be externally generated and is not derived from VCC.
Does S25FL128P0XMFI000 support Quad SPI or Dual SPI modes?
No. The S25FL128P0XMFI000 supports only standard single-data-rate SPI (Mode 0 and Mode 3). It does not implement Quad SPI (QSPI) or Dual SPI command sets. Its SO and SI pins operate in strict half-duplex serial mode; parallel data I/O (PO[7:0]) is available only in the 16-pin SO package and requires x8 Parallel Programming Mode activation.
How is memory protection configured on this device?
Memory protection uses two layers: hardware protection via the WP#/ACC pin (active low), and software protection via four non-volatile Block Protect bits (BP3–BP0) in the Status Register. These bits define contiguous protected sectors; setting SRWD = 1 and driving WP#/ACC low locks the entire Status Register, preventing further BP bit changes until power cycle or Deep Power Down release.
