MAXQ1743：DeepCover Secure Magnetic Card Reader IC

Industry's Only Secure Magnetic Card Reader

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The DeepCover Secure Magnetic Card Reader (MAXQ1743) is an integrated triple-track magnetic stripe reader IC that adds security features to a POS terminal or ATM card reader at the machine/card interface. Card data can be encrypted using either AES or DES/TDES algorithms. Security is further enhanced with the inclusion of fast-wipe nonvolatile SRAM (NV SRAM), a hardware random number generator (RNG), voltage attack sensors, and a self destruct input pin. The NV SRAM clears its contents when a tamper is detected by the on chip tamper detection circuitry. The fast-wipe feature ensures that any data in the NV SRAM is destroyed before any application software can access it. The MAXQ1743 communicates to a host processor through an SPI or I2C interface. Detailed information regarding the operation of the device can be found in the MAXQ1743 User's Guide.
