Alliance Expands CPU Supervisor Family with Edge-Triggered Manual Reset; New Product Additions Target PDA and Handheld Applications with Fixed-Period MR.

SANTA CLARA, Calif. -- Alliance Semiconductor Corporation (Nasdaq:ALSC), a worldwide provider of analog and mixed signal products, high-performance memory products, connectivity and networking solutions for the communications, computing, embedded, industrial and consumer markets, today announced the availability of its ASM161 and ASM162 CPU supervisor products for the mobile and portable market. Targeted for use in products such as PDAs, cell phones and embedded applications, the ASM161/162 include an edge-triggered manual reset, allowing for one-shot timing in pushbutton style reset architectures.

"By implementing an edge detect manual reset input, we've optimized the ASM161/162 for systems requiring a single fixed-period timeout, which significantly enhances data integrity," said Nelson Arata, product marketing manager of Alliance's Analog and Mixed Signal business unit. "By applying this process of supervisory control, Alliance is enabling the system designer with additional flexibility to avoid code corruption or instability due to unpredictable multiple pulses associated with standard-level detection methods."

Alliance's ASM161/162 ICs are cost effective, low-power supervisory circuits designed for monitoring power supplies in a variety of microprocessors and microcontroller-based digital systems. Specifically designed to keep systems from malfunctioning during power-up, power-down or brownout conditions, these ICs include threshold detection to maintain a known state for the microprocessor when power supply voltages are unstable. The edge-triggered manual reset input of the ASM161/162 will react only as the input goes from a high to a low state, generating a pulse of at least 800ms.

The ASM161/162 is part of a growing family of CPU Supervisor products. With the addition of these two new products spanning six different factory set threshold voltages, Alliance now boasts 15 CPU Supervisor product families for a combined portfolio of 149 distinct products. With a growing number of features and functions such as a watchdog timer, battery backup, or power fail indicator, incorporated in each new family of supervisor products, Alliance is committed to meeting the CPU supervisor needs for system design engineers.
