DESCRIPTION

The Teridian 73S8024RN is a single smart card (ICC) interface IC that can be controlled by a dedicated control bus. The 73S8024RN has been designed to provide full electrical compliance with ISO-7816-3, EMV 4.0 (EMV2000) and NDS specifications.

FEATURES
• Card Interface:
▪ Complies with ISO-7816-3, EMV 4.0 and NDS
▪ A LDO voltage regulator provides 3V / 5V to the card
from an external power supply input
▪ Provides at least 90mA to the card
▪ ISO-7816-3 Activation / Deactivation sequencer with
emergency automated deactivation on card removal
or fault detected by the protection circuitry
▪ Protection includes 3 voltage supervisors that detect
voltage drops on VCC (card), VDD (digital), and VPC
(regulator) power supplies
▪ The VDD voltage supervisor threshold value can be
externally adjusted
▪ Over-current detection 150mA max
▪ Card clock stop high or low
▪ 2 card detection inputs, 1 for each possible user
polarity
▪ Auxiliary I/O lines, for C4 / C8 contact signals
▪ Card CLK clock frequency up to 20MHz
• System Controller Interface:
▪ 3 Digital inputs control the card activation /
deactivation, card reset and card voltage
▪ 4 Digital inputs control the card clock (division rate
and card clock stop modes)
▪ 1 Digital output, interrupt to the system controller,
allows the system controller to monitor the card
presence and faults.
▪ Crystal oscillator or host clock, up to 27MHz
• Regulator Power Supply:
▪ 4.75V to 5.5V (EMV 4.0)
▪ 4.85V to 5.5V (NDS)
• Digital Interfacing: 2.7V to 5.5V
• 6kV ESD Protection on the card interface
• Package: SO28, 20QFN or 32QFN
