FUJITSU SEMICONDUCTOR DATA SHEET DS07-13741-2E 16-bit Proprietary Microcontroller CMOS F2MC-16LX MB90945 Series www.DataSheet4U.com MB90F946A/947A/F947/F947A/F949/F949A/ V390HA/V390HB ■ 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.
