Maxim Integrated Products unveils a security manager designed for government and military applications requiring high levels of security by combining internal tamper monitors with tamper-detection inputs that interface with external sensors.

The DS3660 uses 1024B of non-imprinting memory to store sensitive data and to provide the physical tamper-sensing response functions required in cryptographic processors and data security equipment.

The on-chip non-imprinting memory, which consists of eight 128byte banks, can be selectively cleared by end-users based on user-specified tamper events. The 1KB memory is constantly complemented in the background to prevent memory imprinting of data.

Additionally, the device features an internal 1.8V bias source to power low-voltage external SRAM that can be used to store less-critical data, and is configurable to operate with a low-voltage microprocessor for battery-operated devices.

According to the company, DS3660 is an ultra-low-power product that provides tamper detection regardless of the power source targeting ultra-secure applications like government and military systems, as well as any application where more than one tamper-trigger needs to be monitored.

The device's 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.

It draws only 4�A (typ.) of battery current but can retain critical information and still monitor tamper occurrences while on battery power.

The device is not temperature-sensitive and can be used between -55°C to +95°C. It is available in a 7mm x 7mm, lead-free, 49-ball CSBGA package.
