TDK Semiconductor Corp. is sampling the 73S1121F smart card terminal controller, which is claimed by the company to be the first complete SoC for EMV smart card terminals.

The single-chip device includes an 8052 processor, two built-in smart card interfaces with a dedicated hardware ISO7816 UART, multiple development software layers, extensive I/Os, 64KB of Flash, 4KB of user RAM, and PIN pad interface.

These features allow the device to implement the functions needed by smart card terminals for network access security, e-purse terminals, payphones, vending machines, and other POS terminal applications.

"We believe this represents the first complete implementation of a 3G smart card terminal controller," said J. Christophe Doucet, product manager. "First generation systems developed in the mid-90's are separate smart card interface chips connected to a host microcontroller with protocol processing handled through software, while 2G versions are single chip systems, but include relatively few I/O interfaces, not much memory, and limited capabilities overall."

"Our 73S1121F smart card terminal controller includes all the capabilities required for a terminal designer to develop products that can be used in a standalone mode or directly attached to a higher-level controller or PC," said Doucet.

The controller feature a low level API for device control and a high level API includes protocol layers for both asynchronous cards and full-speed USB, plus PIN-management functions for security and payment applications.

The built-in ISO7816/EMV smart card interfaces could be used to simultaneously connect to a user card and to a secure application module for applications such as electronic transactions, e-purse or physical and logical access.

On-chip hardware support for a real-time clock is also provided for synchronous cryptographic applications. The chip also incorporates an intelligent 5x6 keyboard interface, a USB port, and additional I/Os to connect an external LCD driver. Other features include a serial interface, several analog inputs, and a GPIO port for connections that require higher voltages than the chip's normal 2.7V to 3.6V range.
