Product Description
Product Description
- 256byte inner RAM (256 x 8 bits SRAM)1KB outer RAM (1,024 x 8 bits SRAM)48KB program memorizer (48K x 8 bits RM)32KB data memorizer (32K x 8 bits EEPROM)
- 32K 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
- EPROM program voltage generated in the chip
- Asynchronous half-duplex transmission protocol Two kinds of transmission velocity (372/1 and 512/8) optional
- 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 GSM bit error ratio (BER) measurements
