Maxim MAXQ1010 16-bit microcontroller

Maxim has introduced the MAXQ1010, a highly integrated, low-power 16-bit microcontroller that adds security to USB token and USB card reader applications.

Designed with security technology from the company’s ultra-secure financial terminal microcontrollers, the device integrates a true random-number generator and high-speed AES and 3DES encryption engines to support secure communication in USB tokens.

The microcontroller provides a level of security not typically found in USB token applications. It monitors for physical tampering and erases secret encryption keys and sensitive data when under attack.

With 128 KB of integrated flash memory, an integrated USB transceiver and physical interface, a real-time clock, a smart card UART and I/O options, the microcontroller provides a secure single-chip for USB token and USB smart card applications.

It also consumes 6 mA while running its single-cycle 16-bit core at 12 MHz and 400 nA in stop mode (while maintaining its secure memory and monitoring for tamper events). This makes it suitable for a variety of applications: tokens powered only by USB, tokens powered only by a coin-cell battery and portable tokens powered from a battery except when USB power is available.

The device is available in a lead-free, 48-pin TQFN package and operates over the -40 to +85°C extended temperature range.
