General Description
The MAXQ1004 is a low-power microcontroller that integrates a 10-bit ADC, 1-WireM slave interface, SPIK, AES encryption, random-number generator (RNG), and temperature sensor with a 16-bit MAXQM pipelined CPU. Performance bandwidth is sufficient to handle master or slave challenge-response authentication in portable devices.
