Lattice Platform Manager Mixed-Signal ICs

Lattice Semiconductor Platform Managermixed-signal ICs are a single-chip solution that integrates power management and digital board management functions, reducing design costs, enhancing system reliability, and providing a high degree of flexibility. Lattice Platform Manager mixed-signal devices monitor up to 12 voltage rails and support up to 107 digital I/Os. 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, a 10-bit ADC, and a trim block for the trimming and margining of supplies. The digital board management section consists of a 640-LUT FPGA and programmable log interface I/O. Lattice Semiconductor Platform Manager devices are ideal for use in a broad range of applications with complex board management functions. Typical applications include wireless infrastructure, networking core equipment, server, data storage, and high-end industrial instrumentation.
