Product details
Overview
S25FL128SDPBHBC00 from Cypress Semiconductor (now Infineon) is a 128-Mbit serial NOR flash memory with quad SPI interface, 1.8 V supply voltage, and 133 MHz clock frequency. It supports XIP (execute-in-place), dual/quad I/O modes, and sector erase granularity down to 4 KB. Used in embedded boot code storage for industrial controllers and network edge devices.
For engineers reviewing the S25FL128SDPBHBC00 datasheet, S25FL128SDPBHBC00 pinout, S25FL128SDPBHBC00 application, or S25FL128SDPBHBC00 equivalent, key selection criteria include read latency, write endurance, sector protection scheme, and compatibility with legacy SPI boot loaders.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for higher throughput. It features a 256-byte page programming buffer and supports both uniform and hybrid sector architectures (4 KB, 32 KB, and 64 KB sectors).
Internal hardware write protection includes volatile and non-volatile status register bits, block lock-down via WP# pin assertion, and programmable security registers for OTP regions. The device operates across industrial temperature range (−40°C to +85°C) and meets JEDEC JESD22-A117 reliability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB); sufficient for full firmware image plus configuration data in compact MCU-based systems. |
| Interface | Quad SPI (QPI) and standard SPI; enables up to 532 MB/s effective throughput in QPI mode. |
| Supply Voltage | 1.7 V to 2.0 V; compatible with low-power 1.8 V system rails and reduces I/O power consumption. |
| Read Latency | 8 ns address-to-data (at 133 MHz); supports fast boot execution without CPU wait states. |
| Erase Granularity | 4 KB, 32 KB, and 64 KB sectors; allows fine-grained firmware updates while preserving critical boot code. |
| Endurance | 100,000 program/erase cycles per sector; suitable for field-upgradable firmware with frequent patching. |
| Data Retention | 20 years at 85°C; ensures long-term reliability in unattended industrial deployments. |
Pinout & Package
8-pin SOIC (208-mil) package with standard SPI pinout and dedicated Write Protect (WP#) and Hold (HOLD#) control inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SI/IO0 | Serial Input / Quad I/O 0 | Primary data input in SPI mode; bidirectional in QPI for command/address/data multiplexing. |
| SO/IO1 | Serial Output / Quad I/O 1 | Primary data output in SPI mode; bidirectional in QPI for full-duplex high-speed transfers. |
| WP#/IO2 | Write Protect / Quad I/O 2 | Hardware-level sector lock when asserted low; also serves as I/O2 in quad mode. |
| HOLD#/IO3 | Hold Input / Quad I/O 3 | Pauses ongoing transfer without chip deselect; doubles as I/O3 in quad mode. |
| CS# | Chip Select | Active-low enable for command decoding; required for all SPI/QPI transactions. |
| SCLK | Serial Clock | Master-generated clock up to 133 MHz; timing reference for all I/O operations. |
| VCC | Power Supply | 1.8 V core and I/O supply; decoupling capacitor placement critical for noise immunity. |
| GND | Ground | Reference return path for all signals and power; must be low-impedance connection. |
Key Features
| Feature | Design Value |
|---|---|
| XIP (Execute-in-Place) Support | Enables direct CPU instruction fetch from flash without RAM copy, reducing boot time and memory footprint. |
| Quad I/O Mode (QPI) | Doubles data rate vs standard SPI by using four I/O lines simultaneously, improving firmware load speed. |
| Flexible Sector Protection | Combines software (status register bits) and hardware (WP# pin) locking to prevent accidental writes during field updates. |
| OTP Security Registers | Provides 1024 bytes of one-time-programmable space for secure keys or calibration data with permanent write-lock capability. |
| Industrial Temperature Range | Guaranteed operation from −40°C to +85°C, supporting deployment in harsh environments like factory automation and outdoor gateways. |

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 |
|---|---|---|---|
| S25FL128SAGMFV00 | Same density and architecture but in 16-pin SOIC (300-mil) package with different pinout and no HOLD# pin. | Used where board layout requires larger SOIC footprint or simplified hold control is not needed. | Select when mechanical constraints favor 16-pin SOIC or when HOLD# functionality is unused in target design. |
| MX25L12833FZNI-10G | 128 Mbit, 3 V supply, 104 MHz max clock; lacks QPI mode and OTP security registers. | Targeted at cost-sensitive consumer electronics where 1.8 V operation and secure boot are not required. | Choose only if system uses 3.3 V I/O and does not require XIP, QPI throughput, or cryptographic key storage. |
Compared with S25FL128SDPBHBC00, the S25FL128SAGMFV00 offers identical electrical behavior in a mechanically distinct package, while the MX25L12833FZNI-10G trades 1.8 V operation, QPI, and security features for lower unit cost in non-critical applications.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128SDPBHBC00 supports up to 133 MHz in Quad SPI (QPI) mode, delivering up to 532 MB/s effective throughput. This frequency is guaranteed across the full industrial temperature range (−40°C to +85°C) and requires proper PCB layout with matched trace lengths and controlled impedance.
Does this device support hardware reset or power-on reset detection?
No, the S25FL128SDPBHBC00 does not include an internal power-on reset circuit or hardware reset pin. System-level reset must be managed externally via the host processor's reset controller or dedicated PMIC, with CS# held inactive until VCC stabilizes above 1.7 V.
Can the OTP security registers be reprogrammed after initial programming?
No, the 1024-byte OTP security register region is permanently locked after first programming. Once written and verified, further writes to that region are blocked by internal fuse logic, ensuring cryptographic keys or calibration data remain immutable throughout device life.
Is there a migration path to higher-density variants in the same package?
Yes - the 8-pin SOIC (208-mil) package is shared across the S25FLxxS family, including 64 Mbit (S25FL064SDPBHBC00) and 256 Mbit (S25FL256SDPBHBC00) variants. Pinout, timing, and command set are fully compatible, enabling drop-in density upgrades without layout changes.
