MicroTCA The Actel MicroTCA Power Module General Description Actel is enabling the MicroTCA market by providing Fusion-powered reference designs. The Actel Fusion Programmable System Chip (PSC) improves the design of MicroTCA power modules by dramatically reducing part count, board space, system cost, and power while increasing reliability, flexibility, and system availability. The Fusion device includes analog I/O, an analog-todigital converter, FPGA gates, large Flash memory, clocking, and other features that enable it to reduce the part count of the Actel Power Module (PM) reference design by hundreds of parts over other FPGA- and MCUenabled power modules. The analog I/O, digital processing of analog signals, and Flash memory enable improved system monitoring and control so that system reliability and availability increases. As an FPGA, Fusion is the most flexible solution on the market, with in-system reprogrammable microcode and FPGA logic gates. Finally, Fusion improves performance with many functions coprocessed in FPGA gates alongside the Core8051 processor. Actel has reduced the part count required for MicroTCA power module designs in a unique reference design platform that includes hardware, software, and FPGA hardware description language (HDL)—a full solution. Unlike component-driven ASSP designs, the Actel Fusion FPGA enables integration of multiple functions, which include voltage and temperature monitoring, a large Flash memory for event logging, and nonvolatile FPGA fabric for nearly instantaneous hot-swap and power switchover. All of this functionality is delivered today with an Actel Fusion chipset while reducing your bill-ofmaterials cost over ASSP-based power module systems.

The reference design also includes functionally verified hardware, FPGA HDL, and third-party software support. All elements of the design will be thoroughly tested during MicroTCA interoperability testing. For those who want to customize the design, Actel provides the source and can enable a path for turn-key modifications. Signal Stream Technologies has partnered with Actel to offer design services for customizing both hardware and software and will deliver timely engineering support and maintenance services. The Actel Protocol Design Services group can provide modifications to the HDL. For modules in production volume, our partner, MicroBlade™, Inc., offers complete turn-key power modules to your exact specifications. In summary, you can customize the design yourself or have Actel and its partners perform customization. The power module reference design is delivered as a single-board design for the smallest form factor and superior thermal capabilities. Unlike MCU-based designs, which are software-driven and slow, many functions, such as analog-to-digital conversion sequencing and sampling, over-current and under-voltage power switchover, and hot-swap disable, are hardwired. Hardwired fail-safe logic minimizes response time, if there is an unexpected board extraction or system failure. Since payload power current regulation is fully implemented in hardware, the Actel power module is more accurate than MCU-based designs. The current limit for each output channel can be individually programmed in 256 steps with ±1% full-scale accuracy. Likewise, both payload power and management power output voltages are measured with ±1% full-scale accuracy. The power module is also more flexible than anything on the market today. A customer can update the FPGA firmware and application software on-the-fly and can customize hardware, firmware, or software. With a total of 1 MByte of on-board Flash memory, software for the on-chip Core8051 microcontroller can be reprogrammed on-the-fly by uploading code to an isolated buffer in the Flash memory, performing verification, and then switching the context to the new software. Unlike an ASSP-based solution, the Actel controller is an FPGA, so even the "hardware" is reprogrammable, either on the bench using standard FPGA programming tools or insystem via the MicroTCA backplane JTAG interface. A customer can also add differentiation to the hardware design, since Actel provides a full set of design documents, including schematics, a bill-of-materials, layout drawings, and manufacturing drawings. A Power Module That Goes Beyond the MicroTCA Standard The Actel MicroTCA power module is a reference module designed specifically to meet the power conversion, power switching, and form factor requirements to enable MicroTCA applications. It supports a dual –48 VDC input and delivers more than 380 W to the MicroTCA backplane. With the revolutionary form factor made available by the Actel Fusion device, power output levels greater than 700 W are easily possible in a single power module. The monitoring and controller hardware supports input power filtering, conditioning, fusing and monitoring, output power control, monitoring and protection, and DC-to-DC conversion for management and payload power. The Intelligent Platform Management Interface (IPMI) software is IPMI v2.0 compatible and will manage the turn-on sequencing for local AMCs, voltage, and current monitoring, handle abnormal power conditions, and respond to commands and requests from an MCH via the IPMB-0 interface. The module works with a single or dual MCH or as a standalone device without an MCH present in the system. It is compatible with the new PICMG® MicroTCA.0 revision 1.0 standard. The module can turn on each of the management and payload power lines individually, as specified in the MicroTCA specification. It also monitors temperature and power status and reports this back to the MCH. In the case of no MCH, the microcontroller on the module notices that no MCH is present and can execute an onboard preprogrammed system management application. If an AMC is inserted, the power for that slot is turned on and if a module is extracted, the power for that slot is turned off. System application software can be downloaded to the board using the serial port (RS-232) on the front of the module or by the JTAG interface. The IPMB bus on the power module will also monitor temperature and handle fan speed on the cooling module, when that reference design is available. IPMI Debug and Self-Test This power module allows the user to record and insert IPMI commands into any of the I2C busses in the system. This feature is useful for development, debugging, and testing of a system.
