Memorizer (32KB):

• 256 bytes inner RAM (256 x 8-bit SRAM)
• 1KB outer RAM (1,024 x 8-bit SRAM)
• 48KB program memorizer (48KB x 8-bit ROM)
• 32KB data memorizer (32KB x 8-bit EEPROM)

EEPROM (32KB):

• 32KB EEPROM as data memorizer
• Single byte read, write, and wipe
• Multi-bytes storage (1 byte to 1 page)

Program clock come from vibrate clock that generated by chip itself
At the normal temperature, can proceed at least 100,000 times erase and write operations
EEPROM data endurance more than ten years
EEPROM program voltage generated in the chip
Serial I/O interface:

• Match ISO/IEC-7816
• Asynchronous half-duplex transmission protocol
• Two kinds of transmission velocity (372/1 and 512/8)optional

Randomizer: 8 bits
Power on reset: internal power on reset mechanism
Low power work mode: sleep and clock stop
Safety mechanism: abnormal voltage/frequency detection function, DPA/SPS attacking immunity
Working temperature: -25 to +70°C
Working voltage: 2.7V to 3.3V, 4.5V to 5.5V
Working frequency: 1 to 5MHz (3.57MHz)
Can be used in the Agilent 8960 and others to test set when running any GSM test or lab application
Several benefits:

• UMTS security variables within the SIM match the default settings of the GSM test and lab applications
• Set-up time is reduced because the SIM is configured with the same default IMSI and PLMN values broadcast from the test set
• For dual mode testing, GSM speech loopback is supported for Gambit error ratio (BER) measurements
