General Description

The MAXQ1004 is a low-power microcontroller that

integrates a 10-bit ADC, 1-Wire

slave interface, SPIK,

AES encryption, random-number generator (RNG), and

temperature sensor with a 16-bit MAXQ

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.
