Ultra-Low-Power Secure Supervisor with 64 Bytes of Memory and Tamper-Detection Circuitry
Note to Editor:
- The DS3655 is a secure supervisor with temperature and voltage monitoring.
- Addressing the security needs of the POS, PCI, and SDR markets, this device incorporates functions not found in any other single-chip solution.
- The DS3655 integrates a battery-backup controller, system power monitor, CPU supervisor, elapsed-time counter, temperature sensor, and tamper-detection comparator inputs.
- The high integration and advanced security features of the DS3655 make it ideal for point-of-sale terminals, software-defined radios, and other equipment in which data protection and security are critical.

SUNNYVALE, CA—July 2, 2008—Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the DS3655, a secure battery-backup controller and supervisor with temperature and voltage monitoring. This is the industry's only ultra-low-power single-chip device to integrate a battery-backup controller, system power monitor, CPU supervisor, elapsed-time counter, temperature sensor, and tamper-detection comparator inputs. The high integration and advanced security features of the DS3655 make it ideal for point-of-sale (POS) terminals, the payment card industry (PCI), software-defined radios (SDRs), and other equipment in which data protection and security is critical.
The DS3655 has tamper-detection comparator inputs that interface with and provide continuous, ultra-low-power monitoring of resistive antitamper meshes, external sensors, and digital interlocks. This secure supervisor constantly monitors primary power; in the event of failure, an external battery power source is automatically switched in to keep the device and external circuitry alive. The DS3655 also constantly monitors battery voltage and initiates a tamper response when the battery voltage becomes abnormal.
To facilitate recovery analysis, the elapsed-time seconds counter freezes the value of the free-running 32-bit counter when a tamper event occurs. Additionally, the internal digital temperature sensor features user-programmable temperature thresholds and provides a tamper response in the event of thermal attacks.
Each device is inscribed with a unique, 64-bit serial number to provide a distinct ID for tracing purposes. Fully specified over the -40°C to +85°C extended-industrial temperature range, the DS3655 is packaged in a lead-free, 4mm x 4mm, 16-ball CSBGA for added security. Please contact the factory for pricing and availability.
