It uses a Quad I/O SPI interface clocked at 108 MHz, which gives the system a read throughput well above what single-bit SPI can manage — useful for execute-in-place (XIP) boot and over-the-air firmware staging.
Cypress has ended production, and no last-time-buy window remains open. Any inventory available today is surplus or broker-channel stock.
The device is supplied in an 8-WDFN Exposed Pad package, also referred to as 8-WSON (5x6 mm).
Cypress has not published a direct successor for this specific order code. The most practical replacement is another FL-S series part in the same 8-WSON package with Quad SPI and a compatible density — check the S25FL128S or S25FL256S family members for a drop-in footprint match. Verify the exact memory organization and clock speed against your firmware and timing requirements.
Yes, the S25FL127SABNFV103 is listed as Obsolete. Cypress has discontinued production, and no last-time-buy is available. Any procurement must go through surplus or broker channels.
