Lattice tackles power and board management
1 min read
Lattice has launched its third generation of mixed signal devices, called the Platform Manager family. The programmable devices are said by Lattice to simplify board management design by integrating programmable analogue and logic to support common functions such as power management, digital housekeeping and glue logic.
By integrating these support functions, Platform Manager devices can not only reduce the cost of these functions compared to traditional approaches, but also can improve system reliability and provide a high degree of design flexibility that minimises the risk of circuit board respins.
"Lattice transformed board power management design with Power Manager II, which has been adopted across a variety of systems," said Gordon Hands, director of marketing for low density and mixed signal solutions. "We expect customers will adopt the new Platform Manager products, as they expand these same benefits across a broader range of functions."
The family features 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. Both devices include 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 48macrocell cpld; programmable hardware timers; a10bit a/d converter; and a trim block. The digital board management section consists of a 640 look up table fpga and programmable logic interface I/O.
Platform Manager is expected to reduce the number of board components, saving time, board area and design risk. Lattice says that, in many cases, Platform Manager may cut the bill of material cost by 50%.
