Industry's First Secure Battery-Backup Controller From Dallas Semiconductor.DALLAS -- Dallas Semiconductor (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :MXIM) introduces the DS3600, industry's first comprehensive secure battery-backup controller for data protection in point-of-sale terminals. First in a family of secure battery-management products, the DS3600 provides active tamper detection and rapid-erasure key memory. It supports FIPS-140 security levels 3 and 4, and meets the highest requirements of Common Criteria. The DS3600 is packaged in a CSBGA, a preferred choice for certification because no pins are exposed to the outside world so the package is resistant to tampering. Innovative Memory Architecture The memory architecture(1) on the DS3600 is innovative and unique to secure battery-backup controllers from Dallas Semiconductor. Indeed, the memory architecture is what makes this new IC unique. The DS3600's proprietary, on-chip nonvolatile SRAM See static RAM. SRAM - static random-access memory is used for storage of encryption keys. This memory architecture constantly complements the SRAM cells to eliminate the possibility of memory imprinting imprinting, acquisition of behavior in many animal species, in which, at a critical period early in life, the animals form strong and lasting attachments. Imprinting is important for normal social development. due to oxide stresses. As a result, this technology prevents the passive detection of data remnants in stressed memory cells. When the DS3600 generates a tamper alarm, the entire 64-byte array is cleared within 100ns. This erasure of data is this fast because the memory's high-speed direct hardwired clearing function and on-chip power source ensure active erasure Integrated Functions for Comprehensive Tamper Detection and Data Protection It also provides. The DS3600 has tamper-detection inputs to interface with system voltages, resistive meshes, external sensors, and digital interlocks. Using a low-power operation, it also monitors those components continuously. The device monitors the integrated real-time-clock (RTC See real time clock. ) crystal oscillator and will invoke a tamper response if the oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air frequency falls outside the set threshold. The internal digital temperature sensor has a programmable rate-of-change detector that protects the DS3600's encryption key memory from thermal attacks. Competitive secure battery-backup products do not offer such thermal backup protection. The DS3600 constantly monitors primary power. In the event of a power failure, an external battery power source is automatically activated to keep the SRAM, RTC, and tamper detection circuitry alive. Single IC Provides More Security than Larger, More Complex Competitive Solutions Prior to the DS3600, numerous discrete components were required to perform all these same functions. Using the DS3600 enables the designer to minimize board space used to implement a security solution. Due to the secure nature of the DS3600, the product data sheet will not be posted on the Company's website The data sheet, EV kits, and pricing information can, however, be obtained by contacting the business manager, Swati Joshi, at the numbers shown below.
