Product details
Overview
S25FL256SDPBHIC00 from Cypress Semiconductor (now Infineon) is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0 V supply voltage. It supports XIP (execute-in-place), dual/quad I/O modes, and offers 100K program/erase cycles with 20-year data retention. Used in industrial HMIs and network router firmware storage.
For engineers reviewing the S25FL256SDPBHIC00 datasheet, S25FL256SDPBHIC00 pinout, S25FL256SDPBHIC00 application, or S25FL256SDPBHIC00 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, write suspend/resume capability, and JEDEC JESD216B SFDP register support for auto-configuration.
Technical Context
This device implements a standard SPI-compatible command set extended for quad I/O operation, including Fast Read Quad Output (06h) and Quad Page Program (32h). It features a 4-KB uniform sector architecture with individual lock bits per sector and supports both volatile and non-volatile status register writes.
The memory array is organized as 512 pages of 512 bytes each within 512 sectors, enabling precise firmware update partitioning. Built-in ECC (1-bit correction / 2-bit detection) operates transparently during read operations without host intervention.
Key Specifications

| WP# / IO2 | Write Protect / Quad I/O Line 2 | Hardware sector lock control when low; functions as I/O2 in quad mode; active-low polarity |
| HOLD# / IO3 | Hold Input / Quad I/O Line 3 | Pauses ongoing transfer without chip deselect; acts as I/O3 in quad mode; active-low synchronous hold |
| CS# | Chip Select | Active-low enable for command decoding; must be deasserted between transactions to reset internal state |
| CLK | Serial Clock | Edge-triggered input controlling all I/O timing; supports up to 133 MHz with setup/hold margins per datasheet |
| VCC | Power Supply | 3.3 V nominal supply; decoupling capacitor required within 10 mm of pin per layout guidelines |
| VSS | Ground | Reference return path for all I/O and core logic; separate analog/digital ground not required |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with wrap-around burst | Enables continuous 4-byte address increment reads without command reissue, optimizing sequential firmware fetch |
| Individual sector protection | Each 4-KB sector has independent lock bit, allowing bootloader region to remain write-protected while app partitions are updated |
| Write suspend/resume | Allows high-priority read access during long erase operations, critical for real-time HMI responsiveness |
| JESD216B SFDP support | Provides standardized parameter table for automatic driver initialization, eliminating hard-coded timing constants |
| Security register lock | Prevents unauthorized modification of configuration bits (e.g., block protect settings) after factory programming |

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 |
|---|---|---|---|
| S25FL256SAGMFV00 | Same density and Quad SPI interface but in 16-pin WSON package; lacks SOIC option; identical timing and command set | Preferred for space-constrained PCBs where SOIC footprint is prohibitive; requires different layout and thermal relief design | Select when board area is constrained and WSON reflow profile is supported in manufacturing. |
| MX25L25645GMI-13G | 256 Mbit Quad SPI NOR with 133 MHz max clock; no built-in ECC; uses different SFDP parameter layout; 100K P/E cycles | Lower cost alternative where ECC is handled externally or not required; may need driver adaptation due to SFDP differences | Choose for cost-sensitive designs with existing SPI NOR drivers and no requirement for transparent ECC correction. |
Compared with S25FL256SDPBHIC00, the S25FL256SAGMFV00 offers identical functionality in a smaller package but requires WSON assembly capability, while the MX25L25645GMI-13G reduces BOM cost but shifts ECC responsibility to the host MCU and demands SFDP-aware driver tuning.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256SDPBHIC00 supports up to 133 MHz in Quad SPI mode under standard 3.0 V supply and commercial temperature range. This yields 532 MB/s effective throughput using x4 I/O lines. Timing margins are specified in the datasheet's AC characteristics table, and setup/hold requirements must be met at PCB level with proper length matching and termination.
Does this device support execute-in-place (XIP) operation?
Yes, the S25FL256SDPBHIC00 supports true XIP operation via Quad SPI interface. The memory controller can fetch instructions directly from flash without copying to RAM, enabled by continuous burst reads with wrap-around addressing. XIP performance depends on host controller's prefetch depth and cache coherence handling, but the device guarantees deterministic latency for sequential accesses.
How is sector protection configured and locked?
Sector protection is controlled via the Status Register (SR) and Configuration Register (CR). Each 4-KB sector has an individual lock bit set through Write Enable followed by Write Status Register command. The Security Register Lock bit (CR[7]) permanently disables further CR writes once programmed, preventing accidental or malicious reconfiguration of protection settings after factory programming.
Is this part qualified for automotive applications?
No, S25FL256SDPBHIC00 is rated for industrial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive use, Infineon offers the pin-compatible S25FL256SDPBHI00 variant, which undergoes additional stress testing and screening per AEC-Q100 Grade 3 requirements and carries automotive-specific part numbering and traceability.
