Product details
Overview
S25FL128LDPBHB033 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0 V supply voltage, and 133 MHz read clock frequency. It supports XIP (execute-in-place), dual/quad I/O protocols, and offers 100K program/erase cycles with 20-year data retention. Used in industrial PLC firmware storage and embedded boot code applications.
For engineers reviewing the S25FL128LDPBHB033 datasheet, S25FL128LDPBHB033 pinout, S25FL128LDPBHB033 application, or S25FL128LDPBHB033 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, write suspend/resume capability, and industrial temperature range operation (-40°C to +105°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It features a 256-byte page programming buffer and configurable 4-KB/64-KB/256-KB erase sectors.
Internal architecture includes a dedicated command decoder, status register with WEL and BP bits, and hardware write protection via WP# pin. The device supports volatile and non-volatile status register writes for flexible configuration lock-down.
Key Specifications

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 S25FL128SAGMFI000 | Same density and package; uses legacy Cypress process node with lower max clock (80 MHz) and no DDR support | Limited to legacy designs where Quad SPI speed < 320 MB/s suffices | Select if cost sensitivity outweighs performance and future upgrade path |
| Winbond W25Q128JVSIM | 128 Mbit, 3.3 V, but only supports standard/dual SPI (no Quad DDR); 10K erase cycles | Suitable for cost-driven consumer applications without strict industrial endurance requirements | Choose only when Quad DDR and 100K cycle endurance are not required |
Compared with S25FL128SAGMFI000 and W25Q128JVSIM, the S25FL128LDPBHB033 delivers higher throughput, longer endurance, and broader temperature qualification-making it optimal for industrial and automotive boot memory where reliability and speed are co-constrained.

FAQ
Is S25FL128LDPBHB033 compatible with standard SPI controllers?
Yes, it supports standard SPI mode (single I/O) as well as dual and quad I/O modes. Standard SPI operation requires only SI, SO, CS#, and CLK pins; quad mode adds WP# and HOLD# as I/O2/I/O3. Command sets are backward-compatible with legacy SPI flash controllers.
Does this part support execute-in-place (XIP) functionality?
Yes, S25FL128LDPBHB033 supports true XIP operation via Quad SPI interface. The device allows direct instruction fetch from flash memory without copying to RAM, enabled by continuous read mode and address wraparound support for seamless code execution.
What is the sector protection granularity for this device?
It offers three levels: uniform 4-KB sectors (32 sectors), 64-KB blocks (256 blocks), and 256-KB blocks (64 blocks). Protection is controlled via status register bits (BP0–BP3) and hardware WP# pin, allowing fine-grained lockdown of boot sectors while leaving application areas writable.
How does the write suspend/resume feature improve system responsiveness?
During active program or erase operations, issuing a suspend command halts the internal operation within 2 µs, allowing immediate servicing of high-priority read requests. Resume restores the suspended operation without data loss-critical for real-time systems where latency-sensitive reads cannot wait for flash operations to complete.
