The DS8007 is a multiprotocol dual smart card interface that supports all ISO 7816, EMV®, and GSM11-11 requirements. It can directly connect to the nonmultiplexed byte-wide bus of a Maxim secure microcontroller and also access the multiplexed bus of an 80C51-compatible microcontroller through MOVX memory addressing. It provides high-speed automatic smart card processing with support for T = 0, T = 1, and synchronous protocols. It also supports emergency deactivation and a third smart card.
The DS8007 is a low‑cost, multiprotocol dual smart‑card interface supporting ISO 7816, EMV® and GSM 11‑11 requirements. It connects to Maxim secure microcontrollers via an 8‑bit parallel bus (multiplexed or non‑multiplexed) and includes an integrated ISO 7816 UART for independent, variable‑baud‑rate communication with each card.
The device provides full electrical signals for two smart cards, optional third‑card support through auxiliary I/O, and an integrated voltage converter for 1.8 V/3 V/5 V cards across a 2.7 V–6 V supply range. Electrical characteristics, timing parameters, and package information are detailed for design engineers.
