Extractions: January 28, 2003 TDK Semiconductor Corp., a U.S. subsidiary of TDK Corp., announced today the availability of a new smart card terminal controller. The 73S1121F is said to be the first true system on a chip for smart card terminals. This new low-cost device integrates all the functionality for implementing a complete range of smart card terminals for network access security, 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 a dedicated hardware ISO7816 UART, multiple development software layers, extensive I/Os, 64KB of Flash, 4KB of user-RAM, a PIN pad interface, and more on a single chip. This solution will significantly reduce cost and component count for implementing smart card terminals. "We believe this represents the first complete implementation of a third generation 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. Second generation 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 standalone mode or directly attached to a higher-level controller or PC."
