XICOR EXPANDS FAMILY OF CPU SUPERVISORS.

XICOR, Inc. has expanded their complete line of integrated CPU Supervisors with the announcement of the X4163/5, X4323/5, X4643/5 and X4283/5 members of advanced single voltage monitoring, 2-wire CPU supervisors. These devices integrate a low voltage reset, power-on-reset, watchdog timer and various memory configurations including 16K, 32K, 64K and 128Kbit nonvolatile memory depending on device. These new products allow customers to monitor and regulate a single voltage level on a board, thus giving designers the capability to orderly power up or power down their systems as well as save any critical parameter and system configuration data through use of the integrated memory.

The devices are ideal for monitoring and controlling single voltage requirements in communications equipment, metering, industrial control and consumer applications, such as set top and satellite boxes, as well as appliance and automotive applications.

"These single voltage monitoring CPU supervisors fully integrate our broad product offering of system management ICs," said James Tsang, product marketing manager. "By combining key system management functions that designers need to ensure reliable system operation with up to 128K of memory, these CPU supervisor solutions will greatly improve overall system reliability and performance while reducing the component count as well as lowering system cost for the customer."

The feature set of the Xicor 2-wire interface CPU supervisors extend the functionality of these field programmable analog and digital solutions by offering fully integrated memory, up to 128K. In addition to monitoring independent voltages, they feature user-programmable functions that provide system designers with the flexibility to tune device parameters to meet exact system requirements. These products allow the user to select the power on reset points (100-300ms), low voltage reset trip points for the independent low voltage monitor contained in each device, which is independently programmable for low voltage applications. The devices also include adjustable watchdog timeout selection intervals ranging from 200 milliseconds to 1.4 seconds. Moreover, the watchdog timer function, which prevents system lock up, can be disabled to facilitate system software debugging. The various EEPROM memory configurations are integrated in each device and include Xicor's Block Lock feature that prevents data corruption. All products communicate through the industry standard 400kHz two-wire serial interface.
