1-Wire and SPI Authentication Microcontroller
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. The device incorporates 16KB of flash memory and 640B of RAM. Factory programming of a customer secret key is available upon request. The microcontroller runs within a wide 1.7V to 3.6V operating range. For the ultimate in low-power performance, an ultra-lowpower stop mode (300nA typ) is available. In this mode, only a minimum amount of circuitry is powered to support detection of the start of a 1-Wire transaction. When 1-Wire activity is detected, the microcontroller is turned on and the command is executed in an atomic fashion. This allows for stateless operation between comma
