Background|

SIM card (UIM/PIM card) is the unique user ID identifier in the field of mobile communications. It stores in the chip with information of digital mobile phone user and encryption key etc. for mobile communication network to identify the user ID, as well as encrypt voice information when connecting.
The series of contact CPU card chips provided by Tongfang Microelectronics Company meet various demands in the telecom application market.
Features of Product||
- 8051CPU core speed of the chip is 3 times that of standard 51
- program areas and data areas is encrypted
- provide high rate internal clock
