DeepCover Secure Microcontroller with MIPS 4KSd Processor Core

Secure 32-Bit MIPS Processor Supporting Linux OS with Advanced Physical Security and Encrypted External Bus

Please check latest availability status for a specific part variant.


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 Microcontroller (USIP™ Professional IC (USIP PRO)) was 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.

System security is enhanced by a number of physical and logical protection mechanisms including environmental sensors (temperature, voltage, and frequency), active metal shield, real-time clock (RTC), and 512 bits of secure NVM storage (BPK) with instant erase capability upon tampering. For greater privacy, external memory content is fully protected through a universal cryptographic interface (UCI) that performs on the fly AES-128 encryption/decryption. The USIP PRO is one of the most integrated solutions for financial and other trusted terminals. It includes 128KB of SRAM, 128KB of ROM, 256KB of flash, and 256 bytes of OTP. Additionally, the USIP PRO accommodates external memories such as NOR flash, SRAM, and SDRAM.

The device provides extensive communication support with USB On-The-Go (OTG), UART, SPI, I²C, PS/2, IrDA, and parallel SPP. In addition, the USIP PRO offers a unique set of peripherals such as smart card controllers, LCD interface, thermal printer interface, GPIO, PWM, watchdog, general-purpose timers, and a built-in ADC.
