Matsushita Electric announced January 20 that it has developed a systems-on-chip (SoC) IC for embedded use on non-contact smartcards which are based on the Java Card platform developed by Sun Microsystems. The new chip also complies with the e-government Basic Resident Register card standard established by the Japanese government. Designed using a 0.25-micron CMOS four-metal process, the MN103S41H integrates a non-contact analog communications circuit with an ISO/IEC14443 B radio interface, an RSA and elliptic curve encryption coprocessor, and 32KB of non-volatile EEPROM on a 32bit low-power RISC microcontroller.
The 4-million-transistor chip loaded with patent-pending technologies can transfer data at speeds up to 212Kbps. Its digital circuitry consumes 10mW of power and operates on 2.5V.
Matsushita will begin shipping sample quantities of the chip in January.
