Product details
Overview
S25FL128LDPMFB003 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0–3.6 V supply voltage, 133 MHz clock frequency, and uniform 256-byte programming page size. It operates in industrial temperature range (−40°C to +85°C) and supports XIP (execute-in-place) for microcontroller boot code storage in embedded systems.
For engineers reviewing the S25FL128LDPMFB003 datasheet, S25FL128LDPMFB003 pinout, S25FL128LDPMFB003 application, or S25FL128LDPMFB003 equivalent, key selection criteria include Quad SPI timing compliance, sector-erase granularity, write-protection flexibility, and industrial-grade reliability for firmware storage in edge nodes and programmable logic controllers.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with enhanced Quad I/O (QPI) mode for higher throughput. It supports both legacy SPI (single/dual I/O) and QPI (four I/O lines), enabling configurable bandwidth up to 532 MB/s effective data rate. Command set complies with JEDEC JESD216B for SFDP register access.
Internal architecture includes a 128 Mbit (16 MB) array organized as 32 sectors of 64 KB each, with additional 256-byte parameter sectors. Erase suspend/resume and volatile/non-volatile status register configuration provide deterministic firmware update control in real-time systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full bootloader + application firmware image in resource-constrained MCUs |
| Interface | Quad SPI (QPI) - enables 4x faster read throughput vs standard SPI, reducing boot latency |
| Supply Voltage | 3.0–3.6 V - compatible with industrial 3.3 V rail without level-shifting |
| Max Clock Frequency | 133 MHz - supports high-speed sequential reads at up to 532 MB/s effective rate in QPI mode |
| Temperature Range | −40°C to +85°C - qualified for use in industrial automation and outdoor edge devices |
| Programming Page Size | 256 bytes - matches typical MCU cache line and firmware update block alignment |
| Erase Granularity | 64 KB uniform sectors - balances erase time and wear-leveling efficiency for field firmware updates |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 208-mil width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line used for output in standard SPI and bidirectional I/O in QPI mode |
| SI/IO0 | Serial Input / Quad I/O Line 0 | Input-only in SPI mode; bidirectional in QPI; carries command/address/data during writes |
| WP#/IO2 | Write Protect / Quad I/O Line 2 | Hardware write protection when low; serves as I/O2 in QPI for parallel data transfer |
| HOLD#/IO3 | Hold Input / Quad I/O Line 3 | Suspends ongoing serial communication; functions as I/O3 in QPI for full quad-data bus |
| CLK | Serial Clock Input | Master-generated clock synchronizing all SPI/QPI transactions; max 133 MHz |
| CS# | Chip Select Input | Active-low enable signal; initiates command sequence and isolates device on shared bus |
| VCC | Power Supply | 3.0–3.6 V main supply; decoupling required within 10 mm of pin per layout guidelines |
| VSS | Ground | Reference return path for all I/O and core logic; must be low-impedance plane connection |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4-bit-per-clock data transfer, cutting read time by ~75% vs single-I/O SPI for large firmware images |
| Uniform 64 KB Sector Erase | Eliminates need for complex erase mapping logic in bootloader; simplifies field update implementation |
| Volatile & Non-Volatile Status Registers | Allows runtime configuration of write protection and QE bit without requiring power-cycle persistence |

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 |
|---|---|---|---|
| Winbond W25Q128JVSIM | Same density and SOIC-8 package; supports DTR (double-transfer-rate) mode up to 80 MHz, but lacks SFDP v1.6 support. | Requires manual timing configuration in bootloader; less suitable for auto-adaptive firmware loaders. | Select if DTR read performance is prioritized over SFDP-driven portability and future-proofing. |
| Cypress S25FL128SAGMFI001 | Pin-compatible variant with identical electrical specs but different marking and traceability codes; same internal die and revision. | No functional difference; intended for alternate distribution channels and lifecycle management. | Choose for BOM continuity where original part number sourcing is constrained by allocation or lead time. |
Compared with W25Q128JVSIM, S25FL128LDPMFB003 offers superior bootloader interoperability via SFDP v1.6, while the Cypress S25FL128SAGMFI001 provides identical functionality with alternate logistics tracking-making the latter ideal for supply chain diversification without design change.

FAQ
Does S25FL128LDPMFB003 support execute-in-place (XIP) mode?
Yes, it supports XIP mode via Quad SPI interface, allowing direct instruction fetch from flash without copying to RAM. This requires host MCU support for QPI command protocol and proper address remapping. The device's 133 MHz clock and uniform sector layout ensure deterministic latency for real-time interrupt response during XIP execution.
What is the minimum erase block size for firmware updates?
The smallest erasable unit is a 64 KB sector. There is no smaller erase granularity (e.g., 4 KB blocks) supported. Firmware update routines must be designed to back up and rewrite entire 64 KB sectors, which impacts wear leveling strategy and update time-especially for small configuration changes.
Is hardware write protection active by default after power-on?
No, hardware write protection is disabled by default. WP# pin must be actively driven low to enable protection; its state is not latched internally. The non-volatile status register bit (SRWD) can be set to lock register bits, but this does not affect WP# pin behavior unless configured separately via WRSR command.
Can S25FL128LDPMFB003 be used with SPI controllers that lack Quad I/O support?
Yes, it operates in standard single-I/O SPI mode by default. QPI mode must be explicitly enabled via Write Enable and Write Status Register commands. Legacy SPI controllers can access all memory using standard Read/Write commands, though at reduced throughput-no hardware modification or external logic is required for backward compatibility.
