Maxim 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 Maxim's ultra-secure financial terminal microcontrollers, the MAXQ1010 integrates a true random-number generator (RNG) and high-speed AES and 3DES encryption engines to support secure communication in USB tokens.
MAXQ1010: USB microcontroller increases security for token applicationsThe 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 128KB of integrated flash memory, an integrated USB transceiver and physical interface, a real-time clock, a smart card UART, and a wealth of I/O options, the MAXQ1010 provides a highly secure single-chip solution for USB token and USB smart card applications.
The MAXQ1010 also addresses another concern for portable security tokens: power consumption. The microcontroller consumes only 6mA while running its single-cycle 16-bit core at 12MHz, and only 400nA in stop mode (while maintaining its secure memory and monitoring for tamper events). This makes the MAXQ1010 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.
