EMV-COMPATIBLE SMART CARD TERMINALS AS A SYSTEM-ON-A-CHIP SOLUTION!
TDK SEMICONDUCTOR INTRODUCES A NEW SMART CARD TERMINAL CONTROLLER: THE 73S1121F. THIS IS THE INDUSTRY'S FIRST TRUE SOC (SYSTEM ON A CHIP) SOLUTION FOR IMPLEMENTING SMART CARD TERMINALS!
The new chip integrates all the functionality needed for implementing a complete range of smart card terminals, including network access security terminals, e-purse terminals, payphones, vending machines, and inexpensive POS terminal applications.
The 73S1121F includes an 8052 processor, a USB interface, two built-in smart card interfaces with an ISO7816 UART, multiple development software layers, powerful I/O blocks, 64KB of Flash, 4KB RAM, a PIN pad interface and numerous other subsystems. The new solution minimizes the component count needed to implement smart card terminals, which translates into a significant reduction in manufacturing costs.
SOFTWARE LEVELS
The 73S1121F was specifically developed to ease and expedite a company's entry into the smart card terminal business. A low level Application Programming Interface (API) is provided 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.

SMART CARD INTERFACES
The 73S1121F has two built-in ISO7816/EMV smart card interfaces which could be used, for example, to simultaneously connect to a user
card and to a Secure Application Module (SAM) for applications such as electronic transactions, e-purse or physical and logical access.
The device can also be expanded externally to support additional interfaces.
KEY FEATURES
The new chip provides integrated hardware support for a real-time clock, as required by synchronous cryptographic applications, for example. It also incorporates an intelligent 5x6 keyboard interface, a USB port and additional I/Os for connecting an external LCD driver. A serial interface allows connection to a PC, to a higher ranking controller or even to a modem chip. In addition, the 73S1121F includes several analog inputs, reserved I/O lines dedicated to user-specific needs and a GPIO port for connections that require higher voltages than the chip's normal 2.7V to 3.6V range.
CUSTOMER SUPPORT FOR TYPE APPROVALS
TDK Semiconductor offers to help customers through the EMV 2000 Level 1 (EuroPay/MasterCard/Visa) smart card terminal type approval, and provides testing application software. Customers who purchase TDK's 73S1121F will also receive a USB driver sample compatible with the Microsoft® Windows™ Hardware Quality Laboratory test suite. Support in obtaining approvals is a service that TDK Semiconductor also successfully provides to customers who purchase TDK modems, Ethernet transceivers and other mixed-signal products.
