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. 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. * : Controller Area Network (CAN) - License of Robert Bosch GmbH ■ PACKAGE 100-pin Plastic QFP (FPT-100P-M06) MB90945 Series ■ FEATURES 16-bit core CPU; 4 MHz external clock (24 MHz internal, 42 ns instr. cycle time) New 0.35 µm CMOS Process Technology Internal voltage re...
