Security Token Microcontroller
with RTC and USB
General Description
The 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 family contains a 32KB, 64KB, or
128KB programmable flash memory that can be used
for both application code and data storage. Each 512B
flash memory page supports 20,000 erase cycles and is
programmable 16 bits at a time. This allows for unique
schemes to extend the lifetime 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 1KB or 2KB SRAM. An additional
128B secure key storage SRAM is instantly erased when
a self-destruct input is triggered.
The microcontroller also contains a hardware DES engi-
ne 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 generation, and random padding. Firmware
and reference designs are available from Maxim for
authentication applications.
Multiple communication interfaces are implemented; an
integrated USB transceiver and serial interface engine
make USB applications extremely low cost. Other com-
munication options include ISO 7816 UART, SPIK, I2C,
and a standard USART (universal synchronous/asynchro-
nous receiver-transmitter). 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.
