DESCRIPTION

MB91360G Series with up to 3 FULL-CAN Interfaces and 512kB Single Voltage Flash Memory Created in Fujitsu's 0.35µm CMOS process MB91F36x-devices with on-chip Flash ROM and CAN are ideal for a wide range of automotive and industrial applications. MB91F36x parts are being used in high-end instrumentation systems today, where special on-chip features such as stepper motor controllers, real-time watch timer, sound generator, high current LED drivers and PPGs for light dimmers are important.

Some versions contains up to 5 million transistors in 160 logical blocks. The FR CPU clocks at 64MHz internally and is supported by instruction RAM and up to 32kB RAM. All devices have a built-in 512kB flash-ROM memory with 10 years data retention and a minimum of 10,000 erase-cycles. Different programming algorithms can be used such as in-circuit programming, EPROM-programmers or serial programming using the internal boot-ROM (including a security function).

In addition to the special features, a number of general-purpose peripheral blocks are available such as serial communication interfaces, 10 bit A/D and D/A converters, input capture and output compare, reload timers, external interrupts and many more. Power down management features include individual clock-gear functions, sleep and stops modes and reset generation if the voltage drops below a defined threshold plus over / under voltage detection interrupt.

EMC will be more important for the functionality and security of electronic devices. Today's systems require a permanent increase of the clock frequency, high-density PCB layouts with more complex functions and low manufacturing cost. All members of the MB91360-family will therefore be equipped with a new clockmodulator unit which drastically reduces the EME (electromagnetic emission) and helps getting your design EMI-approved! This feature can bring remarkably advantages to your entire system since redesigns due to EMI-problems can be avoided. The modulation of the internal operation clock reduces the noise by spreading the energy of the MCU over a wide frequency range.
