Product details
Overview
S25FL128P0XMFI000M from Cypress Semiconductor is a 128-Mbit, 3.0 V serial NOR Flash memory with uniform 64 KB sectors (256 sectors), SPI interface, 104 MHz max clock rate, and industrial temperature range (–40°C to +85°C). 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), used for firmware storage and code execution in embedded microcontrollers.
For engineers reviewing the S25FL128P0XMFI000M datasheet, S25FL128P0XMFI000M pinout, S25FL128P0XMFI000M application, or S25FL128P0XMFI000M equivalent, key selection criteria include sector architecture (64 KB uniform), WP#/ACC pin functionality for hardware write protection and accelerated programming, SOIC-16 package compatibility, and migration path to S25FL128S.
Technical Context
The device implements a standard SPI bus interface compliant with CPOL=0/CPHA=0 and CPOL=1/CPHA=1 modes, with SI/SO single-bit serial I/O and dedicated HOLD# and WP#/ACC control lines. Internal logic decodes commands (e.g., PP: 02h, SE: 20h/D8h, BE: C7h/60h) and manages status register bits (BP3–BP0, WIP, WEL, SRWD) for memory protection and operation monitoring.
It uses Cypress's 0.09 µm MirrorBit® process to achieve 100,000 program/erase cycles per sector and 20-year data retention. The 16-pin SOIC package supports x8 parallel programming mode, while the WSON variant does not - both share identical command set and timing behavior except for parallel I/O capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 128 Mbit (16 MB), organized as 256 × 64 KB uniform sectors |
| Supply Voltage | 2.7 V to 3.6 V - single supply enables direct integration with 3.3 V system rails without level shifters |
| Max Clock Rate | 104 MHz - supports high-speed read operations (e.g., FAST_READ at 0Bh) for efficient code XIP |
| Page Program Time | 1.5 ms typical - defines minimum latency between successive 256-byte writes during firmware update |
| 64 KB Sector Erase | 0.5 s typical - determines granularity and speed of field-upgradable partition management |
| Data Retention | 20 years typical - ensures long-term reliability for unpowered storage in industrial deployments |
| Endurance | 100,000 cycles per sector - constrains reprogramming frequency in logging or configuration storage use cases |
Pinout & Package
Package: 16-pin SOIC (300-mil body width), RoHS-compliant, lead-free (F), industrial temperature grade (I).
| 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 when low |
| SCK | Serial Clock Input | Drives timing for SI sampling (rising edge) and SO output (falling edge); supports Mode 0 and Mode 3 SPI |
| SI | Serial Input | Receives commands, addresses, and program data; latched on rising SCK edge |
| SO | Serial Output | Transfers read data and status; driven on falling SCK edge; high-impedance when CS# high or HOLD# active |
| HOLD# | Hold Input | Pauses ongoing SPI transaction without deselecting device; requires CS# low to function |
| WP#/ACC | Write Protect / Accelerated Programming Input | Low = hardware write protection; 8.5–9.5 V = enables faster 1.2 ms page program (requires external voltage source) |
| VCC | Power Supply | 2.7–3.6 V main supply; internally generates programming voltages - no external VPP needed for standard operation |
| 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 predictable, fine-grained firmware partitioning and over-the-air update scheduling without sector-size mismatch risk |
| Accelerated Programming via WP#/ACC Pin | Reduces page program time from 1.5 ms to 1.2 ms when 8.5–9.5 V applied - improves production programming throughput |
| Deep Power Down Mode (3 µA) | Minimizes standby current in battery-powered systems during extended idle periods while preserving memory contents |
| Hardware + Software Block Protection | Combines BP3–BP0 status register bits with WP#/ACC pin assertion to prevent accidental erase/write in critical boot sectors |
| Parallel Programming Mode (SOIC only) | Enables x8 parallel data transfer for faster factory programming - not available on WSON variant |

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 part with enhanced reliability, same pinout/package, improved AC characteristics, and extended lifecycle support | Identical use case but with factory-recommended migration path and longer production availability | Select for new designs requiring long-term supply assurance and updated qualification |
| MX25L12833FZNI-10G | Macronix 128 Mbit SPI flash with 133 MHz max clock, 64 KB sectors, and similar 2.7–3.6 V operation but different status register layout and command set | Requires firmware driver adaptation due to non-identical BP bit mapping and erase command codes | Consider only if cross-supplier sourcing or dual-sourcing strategy mandates second-source validation |
Compared with S25FL128S0XMFI000, this part offers legacy design continuity but lacks ongoing lifecycle support; versus MX25L12833FZNI-10G, it provides Cypress-specific toolchain compatibility and known ecosystem integration, though with higher software porting effort than the pin- and command-compatible successor.

FAQ
Is S25FL128P0XMFI000M pin-compatible with S25FL128S0XMFI000?
Yes - both parts use identical 16-pin SOIC (300-mil) packaging and share the same pin functions, electrical characteristics, and command set. Migration requires only PCB-level replacement and firmware verification; no hardware redesign is needed.
What is the function of the WP#/ACC pin beyond write protection?
When 8.5–9.5 V is applied to WP#/ACC, the device enters Accelerated Programming mode, reducing typical page program time from 1.5 ms to 1.2 ms. This requires an external high-voltage source and is used primarily in manufacturing programming stations.
Does S25FL128P0XMFI000M support Quad SPI or Dual SPI modes?
No - this device supports only standard single-data-line SPI (Mode 0 and Mode 3). It does not implement Quad I/O (QPI) or Dual I/O commands; SO and SI operate exclusively as single-bit serial lines per the datasheet specification.
Can the HOLD# pin be used during Deep Power Down mode?
No - HOLD# is inactive during Deep Power Down (entered via DP command B9h). The device ignores all input signals including HOLD#, CS#, and SCK until RES (ABh) is issued to exit Deep Power Down and restore normal operation.
