■ 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 FULL-CAN*
approach. With the new 0.35 µm CMOS technology, Fujitsu now offers on-chip FLASH-ROM program memory
up to 384 K bytes. 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. Up to 3 UARTs, one Serial I/O and one I²C constitute additional functionality for communication
purposes.
