Product details
Overview
S25FL128LDPBHV023 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 1.8 V supply voltage, and 133 MHz read clock frequency. It supports XIP (execute-in-place), dual/quad I/O protocols, and sector-erase capability for embedded firmware storage in microcontroller-based systems.
For engineers reviewing the S25FL128LDPBHV023 datasheet, S25FL128LDPBHV023 pinout, S25FL128LDPBHV023 application, or S25FL128LDPBHV023 equivalent, key selection criteria include quad-SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, and industrial temperature range (-40°C to +105°C) support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad-I/O mode compliant with JEDEC JESD216B. It uses a 64-byte page programming buffer and supports both uniform 4-KB sectors and 64-KB blocks for flexible erase operations.
Internal write-state machine handles erase and program operations autonomously, reducing host CPU overhead. The device includes volatile status register bits for write enable/disable control and non-volatile configuration register settings for default I/O mode and reset behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full bootloader + application firmware images in resource-constrained MCUs |
| Interface | Quad SPI (x4 I/O) - enables up to 532 MB/s effective throughput at 133 MHz clock |
| Supply Voltage | 1.7–1.95 V - matches low-voltage I/O domains of modern ARM Cortex-M and RISC-V SoCs |
| Operating Temperature | -40°C to +105°C - qualified for industrial and automotive under-hood applications |
| Erase Granularity | 4 KB sectors and 64 KB blocks - allows fine-grained firmware updates without full chip erase |
| Write Cycle Endurance | 100,000 program/erase cycles per sector - supports field firmware upgrades over product lifetime |

Key Features
| Feature | Design Value |
|---|---|
| Quad SPI x4 I/O Mode | Enables 4-bit parallel data transfer per clock edge, doubling bandwidth vs dual-I/O mode |
| XIP (Execute-in-Place) | Allows direct code execution from flash without copying to RAM, reducing boot latency and SRAM usage |
| Program/Erase Suspend | Permits read access during background erase or program, enabling real-time interrupt handling |
| Security Register Lock | One-time programmable lock bit prevents reconfiguration of security-related registers 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 |
|---|---|---|---|
| Cypress S25FL128SAGMFV000 | Same density and package, but 3.0 V supply; lacks 1.8 V compatibility | Requires level-shifting when interfaced with 1.8 V MCUs | Select only if system uses 3.0 V I/O domain and legacy design reuse is critical |
| Winbond W25Q128JVSIM | 1.8 V compatible, but rated only to +85°C; no industrial temp grade | Not suitable for under-hood or uncooled industrial deployments | Acceptable for commercial-grade consumer or indoor IoT gateways |
Compared with S25FL128SAGMFV000 and W25Q128JVSIM, the S25FL128LDPBHV023 uniquely combines 1.8 V operation, industrial temperature range, and quad-SPI performance-making it the only option for new designs targeting compact, thermally constrained, and safety-certified embedded systems.

FAQ
Is S25FL128LDPBHV023 pin-compatible with earlier S25FL128P variants?
No. S25FL128LDPBHV023 uses an 8-pin SOIC package with different pin assignments for HOLD# and WP# compared to the 16-pin SOIC of S25FL128P. Physical layout and signal routing must be redesigned; no mechanical or electrical drop-in replacement exists.
Does this device support Dual Transfer Rate (DTR) mode?
No. S25FL128LDPBHV023 supports standard SPI, dual-I/O, and quad-I/O modes per JEDEC JESD216B, but does not implement DTR signaling. Data is sampled on the rising edge of CLK only, not both edges.
Can the security register be unlocked after programming the lock bit?
No. The security register lock bit is one-time programmable (OTP). Once set, it permanently disables further writes to the security register. No hardware or software method exists to reverse this action.
What is the typical power consumption during active read operation?
At 133 MHz quad-SPI read with VCC = 1.8 V, typical active current is 22 mA. This value is measured under JEDEC-standard load conditions and includes internal driver and logic power; actual system-level consumption depends on PCB trace capacitance and drive strength settings.
