ARM7TDMI™ MCU for IC Card Reader/Writer
Features
|
ML675050 is a ARM7TDMI™ based MCU optimized for IC card reader/writers, which supports IC card interface, a variety of serial interfaces, LCD controller and USB2.0 FS host and device controller. ML675050 also includes a Modulo Calculation Accelerator for Encryption/Decryption, which enables RSA cryptography more than 10-times faster than executing by software under the same conditions. A Battery Backup RAM is also integrated for securely storing crypto-key data. Therefore ML675050 is an ideal MCU for ISO7816 complying IC card reader/writer applications that require high performance and security. Application •Banking/Credit Card terminal •ID Card terminal •IC card R/W for e-ticket •Any type of IC card reader/writer |
