HILLSBORO, OR -- 11/09/09 --
Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced the addition of two new higher performance devices to
its second generation Power Manager II product family. Both the
ispPAC®-POWR1014-2 and
ispPAC-POWR1014A-2 devices integrate higher voltage charge pumps with
programmable current to control MOSFETs in Hot Swap and Sequencing
applications. These new devices are pin compatible with existing Power
Manager II devices, and integrate power management functions that typically
require multiple ICs, including Hot Swap Controllers, Reset Generators,
Voltage Supervisors, Sequencers and Trackers. The
ispPAC-POWR1014A-2 device also replaces Analog-to-Digital Converter (ADC)
ICs used for power supply voltage measurements, controlled through a
standard I2C interface.
"Compared to the cost of traditional single function ICs, customers
currently save up to 30% when using our Power Manager II devices to
integrate power management functions in a board with six or more power
supplies," said Shyam Chandra, Lattice's Product Marketing Manager for
mixed signal devices. "Now, with the integration of Hot Swap
functionality, these new, higher performance Power Manager II devices can
save our customers up to 40%."
POWR1014/A-2 Device Architecture
The POWR1014-2 device integrates a 24 macrocell ruggedized PLD
(programmable logic device) and dual precision voltage monitoring
comparators with an accuracy of 0.3%. The POWR1014A-2 device also
integrates a 10-bit Analog to Digital Converter (ADC) for voltage
measurements and an I2C interface that enables a microcontroller to read
the status of all the comparators, inputs as well as outputs. Both the
POWR1014-2 and POWR1014A-2 devices have been ruggedized to operate across a
wide range of power supply voltages from 2.8V to 3.96V. These higher
performance devices generate up to 12V using the on-chip charge pump,
enabling integration of 5V Hot Swap Controllers using MOSFETs with higher
gate threshold voltages.
Power Management Applications
The ispPAC-POWR1014-2, due to its low cost and very small footprint, is
ideally suited to provide a complete board power management solution in
consumer, telecom and automotive applications, including customer premises
equipment (CPE), Plasma Display Panel TVs and in-cabin multimedia. The
POWR1014A-2 device addresses applications such as Advanced Mezzanine Cards
(AMC), PrPMC, basestation line cards, edge router line cards and servers
that require power supply voltage measurement in addition to standard power
management functions.
Software Support
Designs for the ispPAC-POWR1014-2 and the ispPAC-POWR1014A-2 devices are
implemented using the Windows-based Lattice PAC-Designer® Software,
Version 5.2, which is available for download free of charge from www.latticesemi.com/products/designsoftware/pacdesigner
Pricing and Availability
High volume (250KU+) pricing for the ispPAC-POWR1014-2 devices in the
48-pin TQFP package and industrial temperature range is $1.95, with the
ispPAC-POWR1014A-2 devices priced 10% higher. Samples are available now.
