Lattice's new chip cuts cost and complexity
of on-board power management
Lattice Semiconductor is offering programmable power management
chip family with analog, power management and FPGA function
blocks. Lattice calling this device as "Programmable
Platform Manager" The Platform Manager product family
consists of two devices, the LPTM10-1247 and LPTM10-12107.
The LPTM10-1247 device can monitor 12 voltage rails and
supports 47 digital I/O, while the LPTM10-12107 monitors
up to 12 voltage rails and supports 107 digital I/O. Functionally,
these devices include both a power management section and
a digital board management section. The power management
section consists of a programmable threshold, precision
differential input comparator block with an accuracy of
0.7%, a 48-macrocell CPLD, programmable hardware timers,
a10-bit analog to digital converter and a trim block for
the trimming and margining of supplies. The digital board
management section consists of a 640-LUT FPGA and programmable
logic interface I/O.
These single chip programmable devices can replace a couple
of discrete components on board with CPUs, FPGAs and ASICs,
where multiple board-mounted power supplies that need to
be turned on and off in a specific sequence, monitored for
faults and trimmed for voltage accuracy. Also hot-swap functionality,
reset distribution, start-up configuration control for FPGAs
and ASSPs, watchdog timers and a system bus interface for
a microcontroller are supported by this new chip from Lattice.
"Lattice first transformed board power management
design with its Power Manager II products, which have been
enthusiastically adopted across a wide variety of systems
due to the improvements in cost, reliability and design
cycle time they enable," said Gordon Hands, Director
of Marketing for Low Density and Mixed Signal Solutions,
Lattice Semiconductor "We expect that customers will
rapidly adopt the new Platform Manager products, as they
expand these same benefits across a broader range of functions."
The suggested applications for this device include wireless
infrastructure, networking core equipment, server, data
storage and high-end industrial instrumentation.
Availability: Now in samples
Price: High volume pricing for the LPTM10-1247 device
in a 128-pin TQFP package is $3.75.
