 Geneva,
March 5, 2004 - STMicroelectronics (NYSE: STM) has introduced a complete
low-cost analog interface chip for asynchronous 3V and 5V smart cards.
It is designed for use in set-top boxes and IC card readers for banking
and identification.The ST8004 meets the ISO 7816-3 standard and is compatible the NDS conditional access system. It performs all supply protection and control functions when placed between a smart card and a microcontroller. The interface includes a supply supervisor to control transients, enhanced ESD protection on the card side and both thermal and short-circuit protections on all card contacts. The part has three specific protected half-duplex bi-directional buffered I/O lines. It includes automatic activation and deactivation sequences. It also includes a 26MHz crystal oscillator to allow the interface to generate clocks for the card of up to 20MHz, with synchronous frequency changes. The ST8004 runs off a 3 or 5V supply and has a step-up converter for VCC generation. The part also offers under-voltage lockout protection, at 3 or 2.2V. It is available in SO-28 and TSSOP28 packages.
