DESCRIPTION

The MB90945 series with one FULL-CAN interface and FLASH ROM is especially designed for automotive HVAC applications. Its main feature is the on board CAN Interface, which conform to V2.0 Part A and Part B, while supporting a very flexible message buffer scheme and so offering more functions than a normal fullCANapproach. With the new 0.35 µm CMOS technology, Fujitsu now offers on-chip FLASH-ROM program memory up to 512Kbytes. An internal voltage booster removes the necessity for a second programming voltage. An on board voltage regulator provides 3 V to the internal MCU core. This creates a major advantage in terms of EMI and power consumption. The internal PLL clock frequency multiplier provides an internal 42 ns instruction cycle time from an external 4 MHz clock. The unit features a 4 channel Output Compare Unit and a 6 channel Input Capture Unit with two separate 16-bit free running timers. 2 UARTs, one Serial I/O and one I2C constitute additional functionality for communication purposes.
