The Cypress S25FL128S and S25FL256S devices are flash non-volatile memory products using:

  • MirrorBit technology - that stores two data bits in each memory array transistor
  • Eclipse architecture - that dramatically improves program and erase performance
  • 65 nm process lithography
  • S25FL128S/S25FL256S 128 Mbit (16 Mbyte)/256 Mbit (32 Mbyte) 3.0V SPI Flash Memory CMOS 3.0 Volt Core with Versatile I/O Serial Peripheral Interface with Multi-I/O

This family of devices connect to a host system via a SPI. Traditional SPI single bit serial input and output (Single I/O or SIO) is supported as well as optional two bit (Dual I/O or DIO) and four bit (Quad I/O or QIO) serial commands. This multiple width interface is called SPI Multi-I/O or MIO. In addition, the FL-S family adds support for DDR read commands for SIO, DIO, and QIO that transfer address and read data on both edges of the clock.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you. 

Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
