MAX32590 DeepCover Secure Microcontroller Evaluation Kit

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 (MAX32590) provides an interoperable, secure, and cost-effective solution to build new generations of trusted devices such as multimedia-enabled portable EFT-POS terminals. The MAX32590 integrates a Memory Management Unit (MMU), 32KB of instruction cache, 16KB of data cache, 4KB instruction TCM, 4KB data TCM, 384KB of system SRAM, 2KB of One-Time-Programmable (OTP) memory, 128KB of Boot ROM, 24KB of battery-backed SRAM. The MAX32590 maximizes on-chip bandwidth when dealing with high-speed communication such as 100Mbps Ethernet, large color LCD displays, and gigabit-sized mass storage devices. In addition to hardware crypto functions, the MAX32590 provides a true random number generator, battery-backed RTC, nonvolatile SRAM and real-time environmental and tamper detection circuitry to facilitate system-level security for the application. The MAX32590 microcontroller includes multiple communication interfaces. One USB host controller and one USB device controller with their respective USB transceiver, two Smart Card controllers, five SPI ports, three UARTs, an SD/SDHC/SDIO controller, an Ethernet 10/100 MAC with FIFO and an I²C bus are also provided. The three on-chip timers also support PWM output generation for direct control of external devices. An integrated Secure Keypad and Thermal Printer interface provide an integrated solution for mobile POS terminals. Finally a 3-channel 10-bit ADC is provided for printer support and general use.
