EM Microelectronic announces the EMTG30 and EMTG56, a family of flash memory-based smart card ICs designed for use in SIM cards for low-end mobile telephony. The EMTG30/56 are compatible with the ISO7816-3 Integrated Circuit Card (smart card) specification. Memory flexibility is an advantage of the EMTG30/56, which contains 31 and 57 kB, respectively, of pure flash memory. The products feature a high-performance 8-bit market standard 8051 microcontroller core that is implemented in hardware. An internal tamper-proof clock operates at up to 30 MHz. Security is also enhanced by the EMTG30/56’s built-in analog, hardware-protected memory partitioning and tamper notification.
