■ 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.
