Product details

Smart card interface in a small footprint

The MAX1840EUB+ is a specialized interface IC for smart card systems, handling level shifting and protocol bridging between a microcontroller and a smart card slot. It supports MICROWIRE, QSPI, and SPI serial interfaces. Supply range spans 1.4 V to 5.5 V for one side and 1.7 V to 5.5 V for the other. Housed in a 10-pin uMAX/uSOP package.

Package and mounting

Surface-mount assembly in a 10-pin TFSOP/MSOP footprint (3.00 mm body width). The supplier device package is designated 10-uMAX/uSOP. Tube shipment is standard; reel options may be available through the supply channel.

Lifecycle and compliance

ROHS3 compliant, meeting the current EU directive for lead-free and restricted-substance limits. For new designs, this part is a current-production choice with no imminent obsolescence risk.
