The DS8113 is a smart card interface from Maxim that supports 5V, 3V, and 1.8V smart cards and provides low power consumption modes. It supports ISO 7816, EMV, and GSM11-11 applications.
The DS8113 is an analog front‑end designed to interface a system microcontroller with ISO‑7816, EMV™ and GSM‑11‑11 smart cards. It provides power supply, ESD protection and level shifting for 1.8 V, 3 V and 5 V cards and includes an internal voltage regulator and clock generator.
Key features include ultra‑low stop‑mode current (as low as 10 nA), active‑mode current under 1 mA, selectable clock division, high‑current short‑circuit protection, and a wide operating temperature range. The device is supplied in TSSOP packages and is supported by an EMV Level‑1 software library and a reference evaluation kit.
