Fujitsu Introduces 32-bit Microcontrollers With Optimal Features for Electric & Hybrid Vehicle Motor Control
Fujitsu Semiconductor America (FSA) introduced a series of new 32-bit microcontrollers (MCUs) that combine excellent performance with a wide range of peripheral functions to enable optimal, high-speed and highly efficient 3-phase inverter motor control in electric (EV) and hybrid vehicles (HV).
The new MB91580 series is part of the FR family of 32-bit RISC architecture microcontrollers, which incorporate embedded Flash memory and feature optimized, high-performance peripherals for EV and HV 3-phase inverter motor control. Applications include EV/HV motor and electric generator control, as well as generic, high-performance, electric motor control.
What is described as highly efficient loopback control is achieved by using a high-speed, dedicated 12-bit A/D converter and Resolver-to-Digital Converter (RDC). Dedicated hardware generates the required motor control parameters (such as the electrical angle’s sine and cosine values) to accurately detect motor current and position at high speeds, enabling precise motor control waveform generation. The FR81S CPU uses the latest and most advanced FR core to deliver 160DMIPS high-performance calculating power. An IEEE-754-compliant Floating Point Unit enables the MCU to process vector conversion and PID control calculations rapidly, using data from the 12-bit A/D converter and RDC.
According to the company, the resulting solution delivers highly optimized, real-time controllability for EV and HV motors with fast and efficient loopback operation, and the best torque control possible. This level of integration and performance enables system designers to reduce overall motor and motor-control unit costs significantly.
The three members in the series are the MB91F585 (with 576 KB Flash and 48 KB RAM); the MB91F586 (with 832 KB Flash and 64 KB RAM); and the MB91F587 (with 1088 KB Flash and 96 KB RAM).
Opinion: Distributed Generation Drives Industry Transformation
"The MB91580 series is a design choice that is well suited for electric and hybrid vehicles because it is designed specifically to support motor control requirements," said Akio Nezu, Senior Manager for Marketing, Fujitsu Semiconductor America. "These microcontrollers use a dedicated embedded resolver sensor interface to control the three-phase inverter, resulting in optimal motor controllability. This enables the system designer to achieve higher performance while lowering the system cost."
The new MCUs, which are available now, come in 144-pin quad flat packages. Sample pricing starts at $25 each.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
