Smart Card IC
EM Microelectronic announces the EMTCG176-3G, a flash memory-based smart card IC designed for use in SIM and Java cards for GSM mobile phones, as well as for healthcare and loyalty card applications. The EMTCG176-3G is compatible with the ISO7816-3 Integrated Circuit Card (smart card) specification, and operates with high speed communication baud rates. The EMTCG176-3G contains 176 kB of flash memory. The 176 kB non-volatile memory is organized in two sectors of different granularities: 48 kB in pages of 8 B (1 B programmable), and 128 kB in pages of 512 B. The user can decide what amount of code is allocated to the OS and use the remaining space for data. The EMTCG176-3G features an enhanced 8051 microcontroller core compatible with industry standards and implemented in hardware. An internal tamper-proof clock operates at up to 30 MHz. Security is also enhanced by the EMTCG176-3G’s built-in analog, triple hardware DES encryption algorithms, hardware-protected memory partitioning and tamper notification.
