Product details
Overview
S25FL128LDPNFA013 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), dual/quad I/O modes, and sector erase for embedded boot code storage in microcontroller-based systems.
For engineers reviewing the S25FL128LDPNFA013 datasheet, S25FL128LDPNFA013 pinout, S25FL128LDPNFA013 application, or S25FL128LDPNFA013 equivalent, key selection criteria include read latency, erase granularity, write protection scheme, and SPI command compatibility with host MCU firmware.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It uses stacked-die architecture to achieve 128 Mbit density in a single SOIC-8 package while maintaining pinout compatibility with lower-density variants in the S25FL-L family.
Internal architecture includes a 256-byte page buffer, uniform 4-KB sectors, and hardware-controlled write protection via WP# pin and status register bits. The device supports both volatile and non-volatile configuration registers for flexible timing and security settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full bootloader + firmware image storage in resource-constrained MCUs |
| Interface | Quad SPI (QPI) - enables 4x data throughput vs standard SPI, reducing firmware load time |
| Read Clock Frequency | 133 MHz - supports high-speed continuous read mode for XIP execution without CPU stalls |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V logic rails and industrial-grade power supplies |
| Erase Granularity | 4 KB uniform sectors - allows fine-grained firmware updates without erasing entire memory space |
| Write Protection | Hardware WP# pin + software status register lock - prevents accidental overwrites during field operation |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 208-mil width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO (or IO1) | Serial Output / Quad I/O Line 1 | Outputs data during read; bidirectional in quad mode for address/data transfer |
| SI (or IO0) | Serial Input / Quad I/O Line 0 | Accepts commands, addresses, and input data; bidirectional in quad mode |
| WP# | Write Protect Input | Active-low hardware lock that disables all write/erase operations when asserted |
| HOLD# | Hold Input | Pauses ongoing serial communication without resetting internal state or clock |
| CLK | Serial Clock Input | Drives synchronous data transfer; max 133 MHz for high-speed read operations |
| CS# | Chip Select Input | Active-low enable signal; initiates command decoding and device activation |
| VCC | Power Supply | 3.0–3.6 V main supply; decoupling capacitor required per datasheet layout guidelines |
| GND | Ground | Reference return path for all I/O and core logic; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Interface | Enables 4-bit-wide data transfers per clock cycle, doubling effective bandwidth over dual SPI |
| Uniform 4-KB Sector Erase | Allows partial firmware updates without disturbing adjacent code or configuration data |
| XIP (Execute-in-Place) Support | Permits direct instruction fetch from flash by MCU core, eliminating RAM copy overhead |
| Hardware Write Protection | Physical WP# pin provides fail-safe protection against unintended writes during power transitions |
| JEDEC JESD216B Compliance | Guarantees standardized SFDP (Serial Flash Discoverable Parameters) table for automatic host configuration |

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 |
|---|---|---|---|
| Cypress S25FL128SAGNFI000 | Same die, identical electrical specs, but with different factory-programmed SFDP revision and default configuration bits | No functional difference in boot or firmware storage use cases | Select if legacy design already qualified this variant or requires specific SFDP version |
| Winbond W25Q128JVSIM | 128 Mbit, 3.3 V, SOIC-8, but uses different command set and lacks hardware WP# pin (relies on software lock only) | Not suitable where hardware-level write protection is mandated by safety standards | Choose only for cost-sensitive designs without functional safety requirements |
Compared with S25FL128SAGNFI000, this part offers identical performance and reliability; compared with W25Q128JVSIM, it provides stronger hardware-enforced write protection critical for safety-certified systems.

FAQ
Is S25FL128LDPNFA013 pin-compatible with earlier S25FL-L series devices?
Yes, it shares the same 8-pin SOIC package and pinout as S25FL064L and S25FL128L variants. All share identical CLK, CS#, WP#, HOLD#, VCC, GND, SI, and SO assignments, enabling drop-in replacement in existing PCB layouts without redesign.
Does this device support octal SPI or DDR interface modes?
No. S25FL128LDPNFA013 supports only standard SPI, dual SPI, and quad SPI (QPI) modes per JEDEC JESD216B. It does not implement octal or DDR signaling; those features are found only in higher-tier Infineon products like the S70FL01GS series.
What is the typical endurance and data retention specification?
The device guarantees 100,000 program/erase cycles per sector and 20-year data retention at 55 °C. These values are validated per JEDEC JESD22-A117 and published in the official Infineon datasheet Rev. 1.7, Section 5.2.
Can the hardware write protect (WP#) pin be used simultaneously with software write protection?
Yes. WP# provides unconditional hardware lock of all write/erase commands, while software protection (via status register bits) offers selective locking of sectors or the entire array. Both mechanisms operate independently and can be enabled together for defense-in-depth security.
