MCU for auto dash applications

13 February 2002 DSP, Micros & Memory

Fujitsu Microelectronics Europe's MB90V390, the cornerstone of a new MB90390 16-bit microcontroller series, combines Fujitsu's 16LX processor core with many peripheral functions. Its smaller process geometry results in higher operating frequencies and an improved performance/power consumption ratio for the devices. The series offers a reduced CPU cycle time of 50 ns. A patented clock modulator circuit helps reduces noise emission peaks. It is ideally suited to automotive dashboard controls, where EMI emissions are a major problem due to the inability to shield the dashboard and close proximity of radio aerial input. The MB90390 series is equipped with an array of dashboard specific peripherals, including a sound generator, an 18 bit time-base timer and high current output ports for directly driving six stepper motors.
