Product details
Model Number: 2.5G GSM SIM card Brand Name: GRCard Key Specifications/Special Features: High performance ICUsed in smart cardBody material: ABS or PVCCPU: 8 bitsMemorizer (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 chipitself
  • At the normal temperature, can proceed at least 100,000 timeserase and write operations
  • EEPROM data endurance more than ten years
  • EEPROM program voltage generated in the chip
  • Serial I/O interface:
  • Match 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 functionand DPA/SPS attacking immunity
  • Working temperature: -25 to 70°C
  • Working voltage: 2.7 to 3.3 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 whenrunning any GSM test or lab application
  • Several benefits:
  • UMTS security variables within the SIM match the defaultsettings of the GSM test and lab applications
  • Set-up time is reduced because the SIM is configured with thesame default IMSI and PLMN values broadcast from the test set
  • For dual mode testing, GSM speech loopback is supported for GSMbit error ratio (BER) measurements
