Product details
Overview
S25FL128LDPBHB030 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 S25FL128LDPBHB030 datasheet, S25FL128LDPBHB030 pinout, S25FL128LDPBHB030 application, or S25FL128LDPBHB030 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial temperature range operation.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode for high-speed data transfer. It features uniform 4-KB sectors and 64-KB blocks, configurable write protection via status register bits and hardware WP# pin, and supports both fast read (up to 133 MHz) and continuous read modes.
The memory array is organized as 16,384 pages of 256 bytes each, enabling byte-level writes within a page. Erase operations are supported at sector (4 KB), block (64 KB), and chip level, with typical erase times of 0.5 s (sector) and 0.7 s (block).

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 |
|---|---|---|---|
| CY15B104QN-PSOC | 4-Mbit density, FRAM technology, unlimited endurance, but lower capacity and no XIP support | Suitable for frequent parameter logging, not boot code storage due to size and XIP limitation | Select only when byte-level write endurance outweighs capacity and execute-in-place requirements |
| MX25L12833FZCII00 | Same 128-Mbit density and SOIC-8 package, but max 104 MHz read clock and no erase suspend feature | Acceptable for cost-sensitive industrial controls where boot speed and background erase are non-critical | Choose when 133 MHz timing headroom and erase suspend are not required in the design |
Compared with CY15B104QN-PSOC and MX25L12833FZCII00, the S25FL128LDPBHB030 uniquely balances high-density XIP execution, industrial temperature resilience, and field-upgrade-friendly erase management-making it optimal for complex embedded boot and firmware storage where timing, endurance, and reliability intersect.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LDPBHB030 supports up to 133 MHz in Quad SPI mode, delivering up to 532 MB/s effective throughput. This frequency is validated under industrial temperature conditions (–40 °C to +105 °C) with proper signal integrity layout, including controlled impedance traces and minimized stub length.
Does this device support execute-in-place (XIP) operation?
Yes, the S25FL128LDPBHB030 fully supports XIP operation in both standard and Quad SPI modes. The memory array is directly mapped into the processor's address space, enabling CPU instruction fetch without internal RAM buffering-critical for deterministic boot and real-time firmware execution.
How is sector protection implemented?
Sector protection is implemented via two independent mechanisms: software-controlled status register bits (SRWD, BP0–BP3) that lock individual 4-KB sectors, and hardware write protection using the WP# pin. Both methods can be used simultaneously, with hardware protection taking precedence when WP# is asserted low.
What is the typical erase time for a 64-KB block?
The typical erase time for a 64-KB block is 0.7 seconds at 25 °C, with a maximum specification of 1.5 seconds across the full industrial temperature range. Erase suspend/resume functionality allows interruption after as little as 100 ms to service urgent read requests without invalidating the erase operation.
