1-Wire and SPI Authentication Microcontroller
General Description
The MAXQ1004 is a low-power microcontroller that
integrates a 10-bit ADC, 1-Wire^M slave interface, SPIK,
AES encryption, random-number generator (RNG), and
temperature sensor with a 16-bit MAXQ^M 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-low-
power stop mode (300nA typ) is available. In this mode,
only a minimum amount of circuitry is powered to sup-
port 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 commands,
providing the highest reliability and lowest power con-
sumption.
