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 PPGs Current Sensing Gate Driver CPU ADC IGB/ MOSFET M Resolver MB91580 RDC Power Stage Sine / Cosine Signals Excitation MB91580 Motor Control: Current, Positioning Detection and Feedback Control 2 x UDC 2 x DAC 8-bit LVD 3 x ADC x 8ch 12-bit 8 x IRQ ext. 24 x ADC 10-bit NMI Pin Relocation 8 x DMA CRC 12 x OCU 16-bit 8 x ICU 16-bit 24 x PPG 16-bit 6 x FRT 16-bit 4 x RLT 16-bit Diagnostic Fuctions Main Oscillator Sub-clock Oscillator PLLs SSCG PLL RC Oscillator OCD FPU PWR Mgmt Flash Flash Security Work Flash 64kb MPU FR81S 128MHz 4.5 TO 5.5V -40 to + 125˚C 144 pin ECC Flash & RAM Clock Supervisor RAM Watchdog 2 X Base Timer TCON RTC Video Input VRAM Graphics Controller LCDC SMC Sound Waveform Generator RS 3 x CAN 64msg 5 x Multi Func.
