Overview
S25FL256LDPBHI023 from Infineon Technologies is a 256-Mbit serial NOR flash memory IC with quad SPI interface, 1.8 V supply voltage, 133 MHz read clock frequency, and uniform 4-KB sector erase capability. It serves as nonvolatile program/data storage in microcontroller-based embedded systems requiring fast boot code execution.
For engineers reviewing the S25FL256LDPBHI023 datasheet, S25FL256LDPBHI023 pinout, S25FL256LDPBHI023 application, or S25FL256LDPBHI023 equivalent, key selection criteria include quad I/O read throughput, sector protection granularity, write endurance (100K cycles), and industrial temperature range support (−40°C to +105°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode for high-speed data transfer. It supports both single and quad I/O read commands, XIP (execute-in-place) operation, and hardware write protection via WP# pin.
Internal architecture includes a 256-Mbit (32-MB) memory array organized as 65,536 sectors of 4 KB each, with configurable block protection and volatile/nonvolatile status register settings for security and configuration retention.

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 |
|---|---|---|---|
| MX25L25645GMI-10G | 3.3 V supply, 104 MHz max clock, same 256-Mbit density and SOIC-8 package | Requires level-shifting in 1.8 V systems; lower max frequency limits XIP performance | Select when legacy 3.3 V infrastructure exists and quad speed is secondary to cost |
| S25FL256SDPBHI001 | Same 1.8 V supply and 133 MHz spec, but uses 24-ball BGA package instead of SOIC-8 | Not drop-in replaceable due to different footprint and thermal profile | Choose for space-constrained PCBs where BGA routing and thermal dissipation are optimized |
Compared with MX25L25645GMI-10G, S25FL256LDPBHI023 delivers higher read bandwidth and lower power in 1.8 V systems; versus S25FL256SDPBHI001, it offers direct SOIC-8 compatibility for through-hole or legacy reflow processes without redesign.

FAQ
Is S25FL256LDPBHI023 compatible with standard SPI controllers?
Yes, it supports standard SPI modes (0,3) for command and address transmission. Quad I/O functionality requires controller support for extended SPI opcodes (0x6B, 0xEB) and proper pin mapping for IO0–IO3. Legacy SPI-only controllers can operate it in single I/O mode at reduced throughput.
What is the maximum allowable clock frequency for continuous read operations?
The device supports up to 133 MHz for quad I/O fast read commands (0xEB) with appropriate setup/hold timing. At this frequency, sustained read bandwidth reaches 532 MB/s. Single I/O mode is limited to 80 MHz, yielding 80 MB/s peak throughput.
Does S25FL256LDPBHI023 support execute-in-place (XIP) operation?
Yes, it supports true XIP mode: the MCU can fetch and execute instructions directly from flash memory without copying to RAM. This requires alignment of code to 4-KB sector boundaries and proper configuration of the status register's latency and wrap bits.
How is sector protection implemented on this device?
Sector protection is implemented via nonvolatile status register bits (SRWD, BP0–BP3) and hardware WP# pin. When WP# is asserted low, all sectors become read-only regardless of register settings. Software protection allows selective locking of contiguous 4-KB sectors using BP bits, enabling flexible firmware partitioning.
