Alliance Semiconductor Introduces 13 Industry Standard, Low-Power CPU Supervisor Product Families
Alliance Establishes Base for Delivering
Next-Generation System Management Products
SANTA CLARA, Calif.—(BUSINESS WIRE)—April 19, 2004—
Alliance Semiconductor Corporation (Nasdaq:ALSC), a leading
worldwide provider of analog and mixed signal products,
high-performance memory products and systems solutions for the
communications, computing, embedded, industrial and consumer markets,
today announced the availability of its first 13 CPU supervisor
product families. Each of the 13 product families come with multiple
package and reset voltage combinations that spawn 125 distinct
products. These products are a low-power and cost effective
alternative to industry standard CPU supervisors, addressing the 5V,
3.3V and 3V applications in wire-line and wireless telecom, computer,
consumer, industrial and medical markets.
"We have leveraged our expertise in designing low-power ICs to
optimize the power consumption of our CPU supervisors and offer
families of power efficient devices," said Ven Shan, vice president of
marketing, Analog and Mixed Signal business unit for Alliance. "CPU
supervisors have been a standard in applications ensuring robust
system operation. Alliance is establishing a base from which to
integrate the supervisor function with other analog blocks to develop
versatile system management ICs targeting high-performance and
high-reliability systems."
Designed in a sub-micron CMOS process, Alliance's CPU supervisors
operate on power levels that are 20-40 percent less than other
supervisor products currently available in the market. Supervisor
products provide system designers with the ability to monitor and
detect problems related to power supply instability and provide them
with an assured and safe system operation. The table below summarizes
the features offered in the broad product offering. Features range
from the basic power on reset (POR) function, which is used to
maintain the system processor on hold for a minimum of 140ms until the
supply voltage stabilizes, to products that incorporate manual reset
(MR), watchdog timer (WDT), power failure/low battery detection, and
battery backup switching functions that are commonly required in
embedded system applications.
