Product details
Overview
S25FL128P0XNFI003M from Cypress Semiconductor is a 128-Mbit, 3.0 V serial NOR Flash memory with uniform 64 KB sectors, 104 MHz SPI interface, 2.7–3.6 V single-supply operation, and 100,000 program/erase cycles per sector-designed for firmware storage in industrial microcontroller boot applications.
For engineers reviewing the S25FL128P0XNFI003M datasheet, S25FL128P0XNFI003M pinout, S25FL128P0XNFI003M application, or S25FL128P0XNFI003M equivalent, key selection considerations include sector architecture (64 KB uniform), WP#/ACC-accelerated programming mode, Deep Power Down current (3 µA typical), and WSON-8 package compatibility with space-constrained PCB layouts.
Technical Context
The device implements a SPI-compatible serial interface supporting CPOL=0/CPHA=0 and CPOL=1/CPHA=1 modes, with data latched on SCK rising edge and output on falling edge. It uses Cypress's 0.09 µm MirrorBit® process and supports both standard and accelerated programming via external high-voltage injection (8.5–9.5 V) on the WP#/ACC pin.
Memory protection is enforced through non-volatile Status Register bits (BP3–BP0 for 64 KB sector variant), enabling software-configurable read-only regions. Erase operations support sector-level (20h/D8h) and bulk (60h/C7h) commands, with typical erase times of 0.5 s (64 KB) and 128 s (full array).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 128 Mbit (16 MB), organized as 256 uniform 64 KB sectors |
| Supply Voltage | 2.7 V to 3.6 V - enables direct integration with 3.3 V system rails without level-shifting |
| Max Clock Rate | 104 MHz - supports high-throughput firmware reads in real-time embedded systems |
| Page Program Time | 1.5 ms typical (256-byte page) - defines minimum write latency for configuration updates |
| Sector Erase Time | 0.5 s typical (64 KB sector) - determines firmware update granularity and downtime |
| Data Retention | 20 years typical - ensures long-term reliability in unattended industrial deployments |
| Standby Current | 200 µA max - suitable for low-power wake-on-event architectures |
Pinout & Package
Package: 8-pin WSON (6 mm × 8 mm), exposed thermal pad (not electrically connected; optional GND tie with 0 mV potential difference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for SPI command execution; required falling edge after power-up to initialize communication |
| SO | Serial Output | Drives data on falling edge of SCK; high-impedance when CS# high or HOLD# active |
| WP#/ACC | Write Protect / Accelerated Programming Input | Low = hardware block protection; 8.5–9.5 V = enables faster 1.2 ms page programming |
| HOLD# | Hold Input | Pauses ongoing SPI transfer without deselecting device; requires CS# low to function |
| SCK | Serial Clock Input | Controls timing: latches input on rising edge, outputs data on falling edge |
| SI | Serial Input | Receives commands, addresses, and program data on rising edge of SCK |
| VCC | Power Supply | Single 2.7–3.6 V supply powers all read/write/erase functions and internal charge pumps |
| GND | Ground Reference | Return path for all I/O and core logic; must be referenced to exposed pad if tied to GND |
Key Features
| Feature | Design Value |
|---|---|
| Accelerated Programming Mode | Reduces page program time from 1.5 ms to 1.2 ms using externally applied 8.5–9.5 V on WP#/ACC pin |
| Deep Power Down Mode | 3 µA typical current draw - extends battery life in always-on monitoring nodes |
| Hardware + Software Protection | WP#/ACC pin + BP3–BP0 status bits enable dual-layer memory lock against accidental writes |
| Uniform 64 KB Sector Architecture | Enables deterministic firmware partitioning and atomic OTA update blocks without sector-size mismatch |
| MirrorBit® Process Technology | 0.09 µm geometry delivers high endurance (100K cycles) and 20-year data retention at industrial temperature |

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 |
|---|---|---|---|
| S25FL128S0XNFI003M | Successor part with enhanced 133 MHz clock, lower 1.8 V–3.6 V voltage range, and improved 200K-cycle endurance | Designed for new designs requiring extended voltage flexibility and higher throughput | Select for new designs; migration path recommended by Cypress |
| MX25L12833FZNI-10G | 104 MHz max, 2.7–3.6 V, 64 KB sectors, but lacks WP#/ACC accelerated programming mode | Lower-cost alternative where accelerated programming is not required | Use where cost sensitivity outweighs need for 0.3 ms program time reduction |
Compared with S25FL128P0XNFI003M, the S25FL128S offers broader voltage support and higher endurance for next-gen designs, while the MX25L12833F provides identical timing and sectoring without acceleration-making it viable only when WP#/ACC functionality is unused.

FAQ
What is the function of the WP#/ACC pin?
The WP#/ACC pin serves dual roles: when driven low, it enables hardware write protection for memory regions defined by Status Register BP bits; when supplied with 8.5–9.5 V, it activates Accelerated Programming mode, reducing page program time from 1.5 ms to 1.2 ms. It is not a dedicated power pin and must be driven with precise voltage levels to avoid damage or undefined behavior.
Is the exposed pad on the WSON package electrically connected?
No, the exposed central pad on the WSON-8 package is not electrically connected to any internal circuitry. It may be tied to PCB ground only if routing ensures zero voltage difference between the pad and the GND (VSS) lead-otherwise, it must remain floating to prevent latch-up or signal integrity issues.
How does sector erase differ between 64 KB and 256 KB configurations?
This specific part (S25FL128P0XNFI003M) is the uniform 64 KB sector variant, using BP3–BP0 bits and supporting SE commands 20h/D8h. The 256 KB variant uses BP2–BP0 and different sector addressing. Mixing commands or assumptions between variants causes failed erase operations-firmware must match the exact model number's architecture.
Why is Deep Power Down mode critical for battery-powered devices?
Deep Power Down reduces current consumption to 3 µA typical-over 60× lower than standby mode (200 µA). In battery-operated equipment like smart meters or remote sensors, this extends operational life by months or years, especially during long idle periods where firmware state must persist without refresh.
