73S8023C General Purpose Low Power Smart Card IC

Teridian Semiconductor's new 73S8023C is a single smart card interface IC, compliant to the electrical requirements of ISO-7816-3 and EMV 4.0 (EMV2000) electrical specifications. Teridian have designed the device so that it can be used in conjunction with any micro-controller that can support the smart card protocol layer.

The 73S8023C interfaces with the host through a dedicated digital control bus, compatible with the industry-standard devices TDA8004 and TDA8002.

Interface signals coming from the host are internally latched, and latches are controlled by a Chip-Select host input. This allows the host to control multiple Teridian 73S8023C devices through the same control bus.

The smart card clock source can be supplied by the system, or be generated by a built-in oscillator (an external crystal is required). A clock output is available to other 73S8023C ICs when implementing multiple card architectures.
