Product details
Overview
S25FL256SAGBHVB00 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 sector erase granularity down to 4 KB. Used in industrial HMIs for firmware storage and boot code execution.
For engineers reviewing the S25FL256SAGBHVB00 datasheet, S25FL256SAGBHVB00 pinout, S25FL256SAGBHVB00 application, or S25FL256SAGBHVB00 equivalent, key selection criteria include erase block size, write cycle endurance (100K cycles), data retention (20 years), and Quad SPI timing compliance per JESD216B.
Technical Context
This device implements a standard SPI-compatible command set extended for Quad I/O operation, including Fast Read Quad Output and Fast Read Quad Input commands. It features a 256-bit configurable nonvolatile configuration register (NVCR) and volatile status register with write protection bits.
Memory organization consists of one 256-Mbit die divided into 512 uniform 64-KB sectors, each erasable independently. The device supports both hardware and software write protection, including top/bottom sector lockdown and individual sector protection via status register bits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L25645GMI-10G | 256 Mbit, 104 MHz max clock, no DDR mode, standard SPI only | Lacks Quad DDR support; lower throughput limits OTA update speed | Select when system MCU lacks Quad DDR controller or cost sensitivity outweighs bandwidth needs |
| W25Q256JWSIQ | 256 Mbit, 133 MHz, Quad SPI + DTR, built-in ECC, no Secure Silicon ID | Includes on-die ECC for bit error correction but omits hardware-based device identity | Prefer for high-bit-error-rate environments (e.g., high-radiation industrial zones) where ECC adds value over silicon ID |
Compared with MX25L25645GMI-10G and W25Q256JWSIQ, the S25FL256SAGBHVB00 uniquely combines Quad DDR timing, Secure Silicon ID, and AEC-Q100 Grade 2 qualification-making it optimal for safety-critical automotive and medical boot storage where identity binding and extended temperature reliability are mandatory.
