Catalyst Continues Expansion of Its Supervisory Product Family With CAT1232LP and CAT1832 Release.SUNNYVALE, Calif. -- Catalyst Semiconductor, Inc. (Nasdaq:CATS), a leading supplier of high performance analog/mixed-signal solutions and nonvolatile memory See non-volatile memory. , today continued expansion of its Supervisory product family of analog/mixed-signal integrated circuits with the industry standard, low power CAT1232LP and CAT1832 Watchdog Supervisors. The CAT1232LP and CAT1832 are pin compatible and each perform three vital system functions -- power on reset, software watchdog, and manual reset. The combination of these functions in a single device allows system manufacturers to provide customers with superior system operation and reliability with minimal expense and design effort. The CAT1232LP performs the reset and monitoring functions for a 5 volt powered system, while the CAT1832 performs the reset and monitoring functions for a 3 volt powered system. The devices will hold a microprocessor, microcontroller or system chipset in reset until the supply reaches the specified in-tolerance condition; and then maintains the reset condition for a minimum of 250ms before releasing the reset outputs providing time for the power supply to completely stabilize. Once the reset outputs are released, the device immediately starts a watchdog count down clock that is reset each time the watchdog input is strobed. If the watchdog clock should time out, the device will immediately cycle the reset outputs; restarting the system. A debounced manual reset input also allows the device to be connected to an external pushbutton push·but·ton n. also push button A small button that activates an electric circuit when pushed. adj. also push-but·ton Equipped with or operated by a pushbutton. , or other signal, for system restart. These devices are found in virtually all types of applications, but most extensively in industrial/commercial control and monitoring applications, especially those using the 8051 family of processors. "The CAT1232LP and CAT1832 expand Catalyst Semiconductor's supervisory product breadth with two of the most popular products of this type. These supervisors provide a complete supervisory monitoring system on a single chip. They not only monitor the power supply to maintain reliable and consistent operating conditions, but also automatically restart the processor if it hangs for any reason without external intervention," said Jerry Miller, Product Marketing Manager. "Additionally, the watchdog function provides an exceptional benefit in systems that are remote or not easily accessible, reducing potential maintenance costs by automating the system restart process," he concluded.
