Sourcing now runs through independent distribution, where we can locate new-old-stock or surplus inventory against an RFQ. ## 128Mbit SPI Quad I/O NOR Flash — key specs for design fit This is a 128Mbit (16M x 8) SPI Quad I/O NOR Flash memory from Infineon's FL-S series. Rated for 2.7V to 3.6V supply, the S25FL127SABNFV101 operates directly on a 3.3V rail. The SPI and Quad I/O inputs are 3.3V-tolerant, so it interfaces cleanly with most 3.3V MCUs and SoCs without external level translation. If the host runs at 1.8V I/O, a voltage translator on the SPI lines is needed. Supplied in an 8-WDFN with exposed pad, the supplier device package is 8-WSON (5x6).","metaTitle":"S25FL127SABNFV101 128Mbit NOR Flash, Obsolete","metaDescription":"Infineon S25FL127SABNFV101 128Mbit SPI Quad I/O NOR Flash, 108 MHz, 2.7-3.6V, -40 to 105°C, 8-WSON.
