MAX32590
DeepCover Secure Microcontroller
with ARM926EJ-S Processor Core
General Description
Features
DeepCover® embedded security solutions cloak sensi-
tive 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 RAM, 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 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 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 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. Additionally, a 3-channel, 10-bit ADC is provided
for printer support and general use.
