Ultra-low-power security manager provides nonimprinting memory and tamper detection
July 07, 2010 // Paul Buckley
Maxim Integrated Products has introduced the MAX36051 security manager which provides 128 bytes of nonimprinting memory to securely store sensitive data, while drawing little battery power in standby mode (1.5 microamps).
The internal tamper monitors and tamper detection inputs interface with external sensors so that the end user has a greater level of security in their system. With ultra-low power consumption, this device is ideal in devices where small-capacity batteries are used. The MAX36051 is most appropriate for applications where tamper detection and secure data storage are required and low power consumption is critical, as in secure USB, power meter, and point-of-sale (POS) applications.
The MAX36051 is an ultra-low-power device that provides tamper detection regardless of the power source. The on-chip, battery-backup controller function constantly monitors main power (Vcc) and automatically switches to the battery (VBAT) when the main power is too low or not present at all. For battery-power conservation, this security manager has various duty-cycle options that facilitate its low current consumption. Drawing a minimum of 1.5 microamps of battery current, the device can retain critical information and monitor tampers while on battery power alone.
The MAX36051 is fully specified over the -40 to +85 degrees Celsius extended temperature range. It is available in a 4 mm x 4 mm, lead-free, 16-ball CSBGA package.
