New Platform Manager Device Transforms Board Power and Digital Management

Lattice has announced its third-generation mixed-signal devices, the Platform Manager family. The 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 as 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.

Architecture

The Platform Manager 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, a 10-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.

Software Support

The Platform Manager product family is supported by PAC-Designer 6.0 and the Starter version of ispLEVER 8.1 SP1 design software. Both software packages can be dowloaded free-of-charge from the Lattice web site.

Platform Manager Development Kit

The Platform Manager Development Kit, containing an evaluation board complete with demonstration code and documentation, allows users to see known good hardware in five minutes and to recompile the provided source code to get to a known good starting point in 30 minutes.
