Security manager provides superior data protection regardless of power source

23 MAY 2011

Maxim Integrated Products introduces the DS3660, a security manager with 1024 bytes of nonimprinting memory to securely store sensitive data. The on-chip nonimprinting memory, which consists of eight 128-byte banks, can be selectively cleared by end users based on user-specified tamper events. Additionally, the DS3660 device features an internal 1.8V bias source to power low-voltage external SRAM that can be used to store less critical data, and it is configurable to operate with a low-voltage microprocessor for battery-operated devices. Combining internal tamper monitors with tamper-detection inputs that interface with external sensors, this device offers the highest level of system security. The DS3660 is most appropriate for ultra-secure applications like government and military systems, as well as any application where more than one tamper trigger needs to be monitored.
The DS3660 is an ultra-low-power product that provides tamper detection regardless of the power source. The on-chip battery-backup controller constantly monitors the main power (VCC) and automatically switches to the battery (VBAT) when the main power is too low or not present at all. Drawing only 4µA (typ) of battery current, the DS3660 can retain critical information and monitor tampers while on battery power.
