Infotainment Applications

Microchip Technology Infotainment Applications include everything from re-routing due to traffic delays, to providing intuitive visual, auditory, and tactile interfaces. This includes interfaces to the vehicle's distributed and networked subsystems like air conditioning, drivetrain, and body controls. Browse and access a host of media and content or catch up on social media through the onboard connectivity options.

AT25x SPI Serial EEPROMs

Microchip Technology AT25x SPI Serial EEPROMs are designed for use in applications where low-power and low-voltage operations are essential. These EEPROMs feature block write protection, 20MHz clock cycle, self-timed write cycle, write protect pin, and write disable instructions. The AT25x EEPROMs are enabled through the Chip Select pin (CS) and accessed via a 3-wire interface. This 3-wire interface consists of Serial Clock (SCK), Serial Data Input (SI), and Serial Data Output (SO).
