General Description:

DeepCover® embedded security solutions cloak sensitivedata under multiple layers of advanced physical securityto provide the most secure key storage possible.The DeepCover Secure Microcontroller (MAX32590)provides an interoperable, secure, and cost-effectivesolution to build new generations of trusted devicessuch 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 systemRAM, 2KB of one-time-programmable (OTP) memory,128KB of boot ROM, and 24KB of battery-backed SRAM.The MAX32590 maximizes on-chip bandwidth when dealing with high-speed communication such as 100MbpsEthernet, large color LCD displays, and gigabit-sizedmass storage devices.In addition to hardware crypto functions, the MAX32590provides a true random number generator, battery-backedRTC, nonvolatile SRAM, and real-time environmental andtamper-detection circuitry to facilitate system-level security for the application.The secure microcontroller includes multiple communication interfaces. One USB host controller and one USBdevice controller with their respective USB transceiver,two smart card controllers, five SPI ports, three UARTs,an SD/SDHC/SDIO controller, an Ethernet 10/100 MACwith FIFO, and an I2C bus are also provided. The threeon-chip timers also support PWM output generation fordirect control of external devices. An integrated securekeypad and thermal printer interface provide an integrated solution for mobile POS terminals. Additionally, a3-channel, 10-bit ADC is provided for printer support andgeneral use.
