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.
