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：
