Product details
Overview
S25FL128LDPBHV033 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 4-KB sector erase capability. It operates in industrial temperature range (−40°C to +85°C) and supports XIP mode for direct code execution from flash in embedded microcontroller systems.
For engineers reviewing the S25FL128LDPBHV033 datasheet, S25FL128LDPBHV033 pinout, S25FL128LDPBHV033 application, or S25FL128LDPBHV033 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, write suspend/resume support, and industrial-grade reliability for firmware storage in edge-node controllers and automotive body electronics.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode, supporting single/dual/quad read commands per JEDEC JESD216B. It uses stacked-die technology to achieve 128 Mbit density in a single package while maintaining pin compatibility with lower-density family members.
Internal architecture includes a 256-byte page buffer, configurable block protection via status register bits, and hardware write protection using WP# pin. The device supports volatile and non-volatile configuration registers for latency tuning and reset behavior control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full firmware images including bootloader, RTOS, and application code in resource-constrained MCUs. |
| Interface | Quad SPI (QPI) - enables up to 532 MB/s effective throughput using 4-bit data bus at 133 MHz clock. |
| Supply Voltage | 3.0 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of typical board-level voltage ripple. |
| Erase Granularity | Uniform 4-KB sectors - allows fine-grained firmware updates without erasing unrelated application sections. |
| Operating Temp | −40°C to +85°C - qualified for under-hood automotive ECUs and industrial PLC modules requiring extended thermal range. |
| Write Cycle Endurance | 100,000 program/erase cycles per sector - supports field firmware upgrades over multi-year product lifecycle. |
| Data Retention | 20 years at 85°C - ensures long-term integrity of calibration data and configuration parameters in unpowered storage. |
Pinout & Package
Package: 8-pin SOIC (300 mil, Pb-free, RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line used for output during standard SPI reads and input/output during QPI operations. |
| WP#/IO2 | Write Protect / Quad I/O Line 2 | Hardware write protection enable when low; serves as second bidirectional I/O line in QPI mode. |
| HOLD#/IO3 | Hold Input / Quad I/O Line 3 | Pauses ongoing serial transfer without chip deselect; functions as third bidirectional I/O line in QPI. |
| SI/IO0 | Serial Input / Quad I/O Line 0 | Primary input for command/address/data in standard SPI; first bidirectional I/O line in QPI. |
| SCLK | Serial Clock | Master-generated clock synchronizing all SPI/QPI transfers; max 133 MHz operation supported. |
| CS# | Chip Select | Active-low enable signal; initiates command sequence and controls device isolation on shared bus. |
| VCC | Power Supply | 3.0–3.6 V core and I/O supply; decoupling capacitor required within 10 mm of pin. |
| GND | Ground | Reference return path for all internal circuitry and I/O signals; must be low-impedance connection. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Enable (QE) bit in status register | Allows software-controlled transition between standard SPI and QPI modes without hardware change. |
| Program/Erase Suspend | Enables background read access during active erase or program operations, critical for real-time interrupt handling. |
| Individual Sector Protection | Each 4-KB sector can be independently locked via status register bits, preventing accidental overwrite of boot code. |
| Reset Pin (RST#) | Dedicated hardware reset input that restores device to known state independent of CS# timing or power sequencing. |
| Security Register Lock | One-time programmable lock prevents modification of security-related configuration bits after initial setup. |

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 |
|---|---|---|---|
| S25FL128SAGMFV010 | Same density and voltage range but uses smaller 8-pin WSON package (6 × 5 mm); lacks RST# pin. | Preferred for space-constrained PCB layouts where footprint reduction outweighs need for hardware reset control. | Select when board area is critical and reset sequencing is managed entirely by host MCU. |
| MX25L12833FZC-10G | 128 Mbit density, 3.3 V supply, but only supports dual I/O (not quad); max clock 104 MHz. | Suitable for legacy SPI controllers lacking QPI support or where bandwidth < 400 MB/s is acceptable. | Choose when migrating from older Micron-based designs and QPI throughput is not required. |
Compared with S25FL128SAGMFV010, this part offers hardware reset capability and larger SOIC footprint for easier rework; versus MX25L12833FZC-10G, it delivers higher bandwidth and more robust sector protection features essential for safety-critical firmware updates.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LDPBHV033 supports up to 133 MHz in Quad SPI (QPI) mode, delivering up to 532 MB/s effective data rate with 4-bit wide transfers. This frequency is specified under 3.0–3.6 V supply and −40°C to +85°C operating conditions, and requires proper PCB layout with controlled impedance traces and termination.
Does this device support execute-in-place (XIP) functionality?
Yes, the S25FL128LDPBHV033 supports XIP mode through its Quad SPI interface, allowing microcontrollers with QSPI controllers (e.g., STM32MP1, i.MX RT1060) to execute code directly from flash without copying to RAM. XIP requires proper cache configuration and alignment of instruction fetches to 4-byte boundaries.
How is sector protection configured-hardware or software?
Sector protection is configurable via both hardware and software methods: the WP# pin provides hardware-level write protection for all sectors when asserted, while individual 4-KB sectors can be locked/unlocked via status register bits (SRWD, BP0–BP3) using software commands, enabling flexible firmware partitioning.
Is there a dedicated reset pin, and what is its function?
Yes, the device includes a dedicated active-low RST# pin. When pulsed low for ≥20 µs, it forces the flash into a known operational state, clearing any pending commands and resetting internal logic-critical for recovery after brown-out or communication errors without requiring power cycle.
