The MAXQ1050 is a low-power secure microcontroller, designed for USB secure token and smart card reader
applications that require certificate-based or other public key cryptographic schemes. The device uses the 32-bit,
pipelined, MAXQ30 microcontroller CPU. The MAXQ1050 has 128KB flash memory, 12KB of volatile SRAM, 4KB of
battery-backed NV SRAM, and 256B of battery-backed secure zeroization NV SRAM.
The microcontroller is powered either from the USB bus or by a separate 3.3V supply. A battery connection is provided
for applications that need to maintain data in the NV SRAMs. In battery-backed mode, the NV SRAM and security
sensors consume less than 240nA (typ)。
The MAXQ1050 has a number of important features, including:
