MAXQ1004

DeepCover Secure Microcontroller with 1-Wire and SPI

Secure Your Application with Advanced Physical Security and at Low Power


Please check latest availability status for a specific part variant.

Description

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.

The low-power DeepCover Secure Microcontroller (MAXQ1004) integrates a 10-bit ADC, 1-Wire® slave interface, SPI, 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 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 commands, providing the highest reliability and lowest power consumption.

Designers must have the following documents to fully use all the features of this device. The data sheet contains pin descriptions, feature overviews, and electrical specifications. Errata sheets contain deviations from published specifications. The user's guides offer detailed information about device features and operation.
