Product details
Overview
S25FL128LDPBHI030 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 1.8 V supply voltage, 133 MHz clock frequency, and uniform 4-KB sector architecture. It serves as non-volatile program/data storage in microcontroller-based embedded systems requiring fast read access and reliable code execution.
For engineers reviewing the S25FL128LDPBHI030 datasheet, S25FL128LDPBHI030 pinout, S25FL128LDPBHI030 application, or S25FL128LDPBHI030 equivalent, key selection criteria include quad I/O read bandwidth, sector protection granularity, write endurance (100K cycles), data retention (20 years), and industrial temperature range (-40°C to +85°C) compliance.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode supporting single/dual/quad read commands. It uses a floating-gate NOR architecture enabling XIP (execute-in-place) operation without external RAM buffering.
Internal address decoding supports 24-bit addressing across 16 Mbytes of linear memory space. The memory array is organized into 256 uniform 4-KB sectors and eight 64-KB parameter blocks, all individually erasable and programmable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Type | NOR flash - enables direct code execution (XIP) from memory without copying to RAM |
| Capacity | 128 Mbit (16 MB) - sufficient for firmware images, boot code, and configuration data in mid-tier MCUs |
| Interface | Quad SPI - delivers up to 532 MB/s effective read throughput using four data lines |
| Supply Voltage | 1.7–1.95 V - compatible with low-power 1.8 V I/O domains and reduces system power consumption |
| Operating Temp | -40°C to +85°C - certified for industrial-grade embedded control and networking equipment |
| Endurance | 100,000 program/erase cycles - supports frequent firmware updates and field calibration storage |

| SI | Serial Input | Accepts command, address, and data inputs during write/program/erase sequences |
| WP# | Write Protect | Hardware-enabled sector protection; low-active signal locks selected sectors against accidental writes |
| HOLD# | Hold Control | Pauses ongoing serial communication without deselecting device; maintains internal state during bus arbitration |
| CS# | Chip Select | Active-low enable controlling device participation in SPI transactions; required for command initiation |
| SCLK | Serial Clock | Master-generated clock synchronizing all I/O transfers; supports up to 133 MHz in quad mode |
| VCC | Power Supply | 1.8 V core and I/O supply; decoupling capacitor placement critical for noise immunity during high-speed reads |
| VSS | Ground | Reference return path for all internal circuitry and I/O drivers; must be low-impedance connection |

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 |
|---|---|---|---|
| S25FL128SAGMFI000 | Same density and voltage, but uses 16-pin SOIC package and supports octal DTR interface up to 200 MHz | Targeted at high-bandwidth applications like AI edge accelerators requiring faster boot and firmware load | Select when board layout allows larger package and system demands >133 MHz read throughput |
| MX25L12833FZNI-10G | 1.8 V, 128 Mbit, but rated only for commercial temperature (0°C to +70°C) and lacks program/erase suspend | Suitable for cost-sensitive consumer electronics where industrial temp grade and real-time suspend are not required | Choose only for non-industrial designs with relaxed environmental and latency requirements |
Compared with S25FL128SAGMFI000, this part offers smaller footprint and lower power but less bandwidth; versus MX25L12833FZNI-10G, it provides guaranteed industrial operation and enhanced real-time interrupt capability during flash operations.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LDPBHI030 supports up to 133 MHz in Quad I/O read mode, delivering 532 MB/s effective throughput. This frequency is specified under 1.8 V supply and industrial temperature conditions, and requires proper PCB layout with matched trace lengths and controlled impedance.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports XIP directly from the NOR flash array. Its architecture allows CPU instruction fetches without prior loading into RAM, reducing boot latency and simplifying memory mapping in resource-constrained microcontrollers.
How is sector protection implemented on this flash memory?
Sector protection is implemented via both software (status register bits BP0–BP3) and hardware (WP# pin). When WP# is asserted low, selected 4-KB sectors become read-only; software protection allows fine-grained locking per sector group without external pin control.
Is there built-in error correction for read operations?
No, the S25FL128LDPBHI030 does not include on-die ECC. Error detection and correction must be handled externally by the host controller or firmware using Hamming codes or BCH algorithms, especially for applications requiring high data integrity over extended retention periods.
