General Description
The USIP™ Professional IC (USIP PRO) is a secure microcontroller designed to provide an interoperable, secure, and cost-effective environment for new generations of trusted devices. This secure platform is fully compliant with EMV® and PCI PED standards. The USIP PRO is based upon the most secure, 32-bit, RISC core (MIPS32® 4KSd™) from MIPS Technologies. While providing superior performance (1.35MIPS/MHz), this low-power core adds special instructions to accelerate cryptographic operations and security functions to enforce system integrity. Complemented by a secure memory management unit (MMU), the USIP PRO can run feature-rich operating systems such as Linux® in a secure way.
