FS fact sheet MB91580 Series 32-bit Motor Control MCU for Electric (EV) and Hybrid Electric Vehicles (HEV) 0Description0 The new MB91580 series, a part of the Fujitsu FR family of 32bit RISC microcontrollers (MCUs), offers 3-phase inverter motor control and an embedded resolver interface for electric (EV) and hybrid electric vehicles (HEV). The MCU series offer high performance combined with optimized peripherals for electric and hybrid electric vehicles. The MB91580 series was designed to provide special features for efficient loopback control. The device offers a 12-bit Analog to Digital Converter (ADC) and a 12-bit Resolver to Digital Converter (RDC) to detect motor current and position at high speed and with high resolution. The electric angle of the revolver, which is calculated by the RDC, is latched into dedicated registers and synchronized with the three phase current detected by the ADC. Control algorithms will benefit from the floating point Unit (FPU) and will speed up vector conversion and calculations using decimal point numbers by 10-15% compared to standard integer processing. The MB91580 series feature Fujitsu’s advanced Flash memory technology, including dedicated program memory and a separate work Flash for EEPROM emulation storage. 0Applications0 • Generic electric motor control • HEV/EV inverter • HEV/EV generator control Gate Driver PPGs CPU ADC MB91580 Current Sensing IGB/ MOSFET M Resolver Power Stage RDC Sine / Cosine Signals Excitation MB91580 Motor Control: Current, Positioning Detection and Feedback Control 2 x UDC 2 x DAC 8-bit 3 x ADC x 8ch 12-bit 24 x ADC 10-bit Pin Relocation CRC 12 x OCU 16-bit LVD 8 x IRQ ext.
