The Platform Manager™ product family represents the third-generation of mixed-signal devices available from Lattice. Programmable Platform Manager devices simplify board management design significantly by integrating programmable analog and logic to support many common functions, such as power management, digital housekeeping and glue logic. By integrating these support functions, Platform Manager devices not only reduce the cost of these functions compared to traditional approaches, but also improve system reliability and provide a high degree of design flexibility that minimizes the risk of circuit board re-spins.
Platform Manager is shown below in a board application where it is providing power management functions to detect faults across up to 12 supplies, margin and trim up to 8 supplies, capture and integrate 12V hot swap. It is also providing digital support including log information to NV memory, flexible reset distribution and configuration of payload ICs at power-on.
The Platform Manager Development Kit allows the designer to quickly configure and evaluate the Platform Manager LPTM10-12107 ftBGA device on a fully assembled printed-circuit evaluation board.
Preloaded designs allow the user to immediately evaluation functions such as power supply sequencing, voltage monitoring, fault logging and trim and marginning of power supplies. Also demonstrated are I/O to an on circuit board LCD and various switch/LED control interfacing techniques. More Platform Manager reference designs specifically targeted for the evaluation board are available for download from the Lattice Website.
