MB90342CE数据手册Fujitsu中文资料规格书

描述 Description

■ DESCRIPTION
The MB90340E-series with up to 2 FULL-CAN* interfaces and Flash ROM is especially designed for automotive and other industrial applications. Its main feature are the on-board CAN Interfaces, 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 512 Kbytes.
The power to the MCU core (3V) is supplied by a built-in regulator circuit, giving these microcontrollers superior performance in terms of power consumption and tolerance to EMI.■ FEATURES
