Security manager from Maxim draws only 1.5µA in standby mode

Maxim has unveiled the MAX36051 security manager. It provides 128 bytes of nonimprinting memory to securely store sensitive data, while drawing small amount of battery power in standby mode (1.5µA). 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. This device is suggested for devices where small-capacity batteries are used and is considered to be 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.

Some of the key features of the MAX36051 are:
1. MAX36051 provides tamper detection.
2. Consists of an on-chip, battery-backup controller function that constantly monitors main power (VCC) and automatically switches to the battery (VBAT) when the main power is too low or not present at all.
3. This security manager has various duty-cycle options that facilitate its low current consumption.
4. Drawing a minimum of 1.5µA of battery current, the device can retain critical information and monitor tampers while on battery power alone.

Package: 4mm x 4mm, lead-free, 16-ball CSBGA

Operating temperature range: -40°C to +85°C
