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.
