Maxim MAXQ1004 16-bit microcontroller

Maxim has introduced the MAXQ1004, a low-power 16-bit microcontroller that can add secure authentication to any application.

Designed with the same security technology as the company’s ultra-secure financial terminal microcontrollers, the device integrates a true random-number generator and a high-speed AES encryption engine supporting 128-, 192- and 256-bit key sizes.

These features enable the most secure authentication and communication schemes, while resisting analytical and cryptanalysis attacks.

This type of authentication is appropriate for use in protecting revenue streams (battery pack authentication), validating peripherals (video game controllers) and implementing secure communication schemes (automotive keyfobs).

With 16 KB of integrated flash memory and multiple communication options (including SPI and 1-Wire interfaces), it is flexible enough to be programmed for any kind of secure authentication application.

In addition to providing robust authentication, the microcontroller consumes little power, making it suitable for applications where power consumption must be kept to a minimum.

When operating at 6 MHz, the single-cycle device consumes 3.75 mA; in its lowest power stop mode, it consumes 300 nA. For applications like digital still cameras, its effect on overall battery consumption is negligible. However, for coin-cell-powered applications like keyfobs, the device provides long battery life - running from a 64 mAh battery with a 0.1% duty cycle will last for 1.8 years, and with a duty cycle of 0.01%, the battery will last for over 10 years.

A wide operating range (1.7 to 3.6 V) allows it to run from two AA batteries.

The microcontroller is available in a lead-free, 16-pin TQFN package and operates over the -40 to +85°C extended temperature range.
