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.
