System management design tools for wired and wireless communications applications

May 02, 2012 // By Jean-Pierre Joosting
Microsemi Corporation has introduced a suite of system and power management design tools for high availability wired and wireless communications infrastructure equipment. The design tools include Microsemi's Mixed Signal Power Manager (MPM) 4.0 reference design, which supports up to 64 power rails and mixed analog and digital point-of-loads (POLs), as well as PMBus™-based communication. The company also offers an evaluation kit that can be used with Microsemi's SmartFusion® customizable system-on-chip solution (cSoC) to enable quick product-functionality assessments.

"Our new power management solution significantly reduces the cost and complexity of board-level power management design by integrating system management functions required in communications infrastructure applications," said Esam Elashmawi, vice president and general manager at Microsemi.
Microsemi's comprehensive MPM 4.0 power management solution includes a graphical user interface that simplifies the visualization of the power sequencing and margining that occurs in complex high availability systems. In addition, trimming, event logging and alarm generation are supported. MPM 4.0 also includes a reference design containing all sources files and firmware, allowing customers to customize products and support a mix of power rails.

An evaluation kit to accelerate initial design testing and experimentation is also offered. The kit includes Microsemi's SEU-immune SmartFusion cSoC, which is offered in standard or military temperatures in a variety of packages. SmartFusion devices include an integrated FPGA, an ARM Cortex™-M3 processor, and programmable analog in a single device. The kit also includes Microsemi's NX9415 3.3 V and LX9610 1.5 V nominal regulators. Additional features include: support for up to 64 channels, both analog and digital POL support, PMBus support for digital POL, and margining and trimming for analog POL.
