General DescriptionDeepCover® 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 (MAXQ1010)
is a small, low-cost, low-power secure microcontroller
designed for security token applications and battery-
powered applications where power and security are both
critically important.
The microcontroller contains a 128KB programmable
flash memory that can be used for both application code
and data storage. Each 512B flash memory page sup-
ports 20,000 erase cycles and is programmable 16 bits at
a time. This allows for unique schemes to extend the life-
time of the flash. For instance, dedicating four flash pages
to store 32B of data that changes very often, the effective
number of write cycles can approach 1.2 million (4 x 512
x 20,000/32). The device also contains 2KB SRAM. An
additional 128B secure key storage SRAM is instantly
erased when a self-destruct input is detected.
The microcontroller also contains a hardware DES engine
and an AES accelerator, allowing applications to quickly
respond to challenges and authenticate other devices
using standards-based cryptography. A true-hardware
random-number generator (RNG) is available for general
application use, such as key generation, challenge gen-
eration, and random padding. Firmware and reference
designs are available from Maxim Integrated for authenti-
cation applications.
Multiple communication interfaces are implemented: an
integrated USB transceiver and serial interface engine
make USB applications extremely low cost; also included
are an ISO 7816 UART, SPI, I2C, and a standard USART
(universal synchronous/asynchronous receiver-transmit-
ter). A real-time clock (RTC) is also included for security
applications requiring a time base.
For the ultimate in low-power battery-operated perfor-
mance, an ultra-low-power stop mode (400nA typ) is
included. In this mode, the minimum amount of circuitry
is powered. Wake-up sources include external interrupts,
the power-fail interrupt, a wake-up timer interrupt, and an
RTC interrupt.
