DeepCover Secure Microcontroller with ARM926EJ-S Processor Core

High-Performance, Single-Chip Secure Microcontroller with Encrypted External Bus and Advanced Physical Security



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 (MAX32591) provides an interoperable, secure, and cost-effective solution to build new generations of trusted devices such as multimedia-enabled portable EFT-POS terminals. The MAX32591 integrates a memory management unit (MMU), 32KB of instruction cache, 16KB of data cache, 4KB instruction TCM, 4KB data TCM, 384KB of system RAM, 2KB of one-time-programmable (OTP) memory, 128KB of boot ROM, and 24KB of battery-backed SRAM. The MAX32591 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 MAX32591 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 secure 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 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 provides an integrated solution for mobile POS terminals. Additionally, a 2-channel, 10-bit ADC is provided for printer support and general use.
