73S8010C - Teridian Semiconductor

73S8010C Smart Card Interface

The Teridian 73S8010C is a single smart card interface IC. It provides full electrical compliance with ISO-7816-3 and EMV 4.0 specifications. Interfacing with the host is done through the two-wire I2C bus. Data exchange with the card is managed from the system controller using the I/O line (and eventually the auxiliary I/O lines). An on-chip oscillator using.

Features

 Card Interface:
 Complies with ISO-7816-3 and EMV 4.0
 A DC-DC Converter provides 3V / 5V to the card from an external power supply input
 High-efficiency converter: > 80% @ VDD= 3.3 V, VCC = 5 V and ICC = 65 mA
 Up to 100 mA supplied to the card
 ISO-7816-3 Activation / Deactivation sequencer with emergency automated deactivation on card removal or fault detected by the protection circuitry
 Protection include 2 voltage supervisors that detect voltage drops on card VCC and VDD power supplies
 The VDD voltage supervisor threshold value can be externally adjusted
 True over-current de.
