Dongguan Hele Electronics Corporation

Model Number: 3G CDMA2000 TEST CARD Brand Name: GRcard Key Specifications/Special Features: Specifications:High performance ICUsed in smart cardBodymaterial: ABS or PVCCPU: 8 bits

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 precede at least 100,000 times erase and write operating EEPROM data endurance more than ten years EEPROM program voltage generated in the chip

Serial I/O interface:

• With IEC-7816 marks
• 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 and DPA/SPS attacking immunity
• Working temperature: -25 to 70°C
• Working voltage: 2.7 to 3.3V and 4.5 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

Advantages:

• 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 loop back is supported for GSM bit error ratio (BER) measurements
