Product details
Overview
S25FL256SAGBHI210 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 PLC firmware storage and embedded boot code retention.
For engineers reviewing the S25FL256SAGBHI210 datasheet, S25FL256SAGBHI210 pinout, S25FL256SAGBHI210 application, or S25FL256SAGBHI210 equivalent, key selection criteria include erase/write cycle endurance (100K cycles), data retention (20 years), Quad SPI timing compliance, and SOIC-16 package compatibility with legacy PCB footprints.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It uses a 64-byte page programming buffer and supports both uniform and configurable sector protection via status register bits.
Internal architecture includes a 256 Mbit (32 MB) array organized as 512 sectors of 64 KB each, with optional 4 KB subsector erase capability enabled by configuration register bit CR[2]. Write protection is hardware- and software-enabled.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256SAGBHI210 supports up to 133 MHz in standard Quad SPI mode, delivering 532 MB/s effective throughput. This is validated across the full industrial temperature range (−40°C to +85°C) and requires controlled impedance routing and proper termination per the datasheet layout guidelines.
Does this device support execute-in-place (XIP) operation?
Yes, the S25FL256SAGBHI210 supports true XIP mode via Quad SPI, allowing the host microcontroller to fetch instructions directly from flash without copying to RAM. This reduces boot latency and eliminates SRAM footprint for code storage in resource-constrained MCUs.
How is hardware write protection implemented?
Hardware write protection is activated by pulling the nWP pin low, which locks the status register and prevents modification of sector protection bits. This protection remains active regardless of SPI command state and survives power cycles, ensuring firmware integrity during field operation.
Is the SOIC-16 package lead-free and RoHS compliant?
Yes, the S25FL256SAGBHI210 in SOIC-16 packaging uses matte tin-plated gull-wing leads and complies with RoHS Directive 2011/65/EU and JEDEC JS-001 ESD standards. Lead finish is Pb-free, and the device meets IPC/JEDEC J-STD-020 moisture sensitivity level 3.
