DESCRIPTION

The MB90545 series with FULL-CAN and FLASH ROM is specially designed for automotive and industrial applications. Its main features are two on board CAN Interfaces (one for MB90V545 series), which conform to V2.0 Part A and Part B, supporting very flexible message buffering. Thus, offering more functions than a normal full CAN approach. In latest CMOS technology Fujitsu offers on-chip FLASH-ROM program memory. An internal voltage booster substitutes the necessity of a second programming voltage. An on board voltage regulator provides 3V to the internal MCU core. This constitutes a major advantage in terms of EMI and power consumption. The internal PLL clock frequency multiplier, provides an internal 62.5 nsec instruction cycle time with an external 4 MHz clock. Further more it features 4 channels Output Capture Units and 8 channels Input Capture Units with a 16-bit free running timer. Two UARTs constitute additional functionality for communication purposes. The external bus interface allows full use to be made of the 16MByte address space.
