Netezza, an IBM Company, Selects Lattice Power Manager Products

HILLSBORO, OR, Nov 14 (MARKET WIRE) --
Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced that
Netezza, an IBM Company and the leader in data warehouse appliances, is
using the innovative programmable Lattice Power Manager device -- the
PAC(TM) POWR 1220AT8 -- to integrate and simplify multiple power
management functions in a board design.

As board designs become ever more complex, the traditional approach to
power management using multiple discrete power management ICs from
several different vendors is no longer viable from a board cost,
reliability and time to market perspective. Instead, what is needed is an
approach that integrates diverse power management functions into one
power management IC, and Lattice's Power Manager devices are increasingly
the "chip of choice" for board designers.

"We chose the Power Manager device to help us deal with several board
design and power management challenges," said Ken Schwartz, Netezza
Technology Director for hardware development. "For example, the
proliferation of voltage regulators due to a distributed power
architecture presented us with the challenge of replicating all the
individual monitoring, control, and margining circuits. Power sequencing
of complex ICs and memories require that almost every voltage rail be
individually controlled. Programmability helps during debugging and
stress testing. We also wanted finer resolution of margining under
computer control, rather than using switches to connect and disconnect
two margining resistor values. Further, we needed a power controller that
can work with a mix of regulators from different vendors, and the Lattice
Power Manager can do that.

"Other Power Manager features that appealed to us were the ability to use
the integrated CPLD for small amounts of glue logic and programmable I/O;
a way to compensate for voltage drops due to PCB characteristics or load
variations; and the voltage feedback control, which could be effective
with 24A 1.0V devices that have huge current variation potential. The PAC
POWR 1220AT8 was able to solve all these design challenges for three
generations of board designs," Schwartz concluded.

Netezza used the Power Manager to integrate several functions, including:

-- Voltage Monitoring + Over/Under Voltage Detection and Notification
with much higher accuracy

-- Voltage Margining: Replaced a discrete switch and two resistors with a
table-driven
DAC approach with up to 256 margin points

-- A general purpose I2C I/O register

-- Random glue logic

-- FET drivers for Power MOSFETS

"Our customers are rapidly discovering the new, innovative way to
look at power management," said Shyam Chandra, Senior Product Marketing
Manager for Lattice's mixed-signal devices. "Not only does the Power
Manager simplify power management through integration, it also reduces
board cost and increases board reliability. And, because Power Manager is
programmable, changes to the board design are easily accommodated."
