F2MC-16LX Family

16-bit Microcontroller Mounted with Dual-Operation Flash Memories

MB90890 Series

A new F2MC-16LX CPU-driven microcontroller series is available with 64 K-byte dual-operation flash memories and a CAN controller integrated in a compact

48-pin package. This is the world first lineup of microcontrollers mounted with dual-operation flash memories.

Product Description

The new series provides the world first high-performance 16-bit CPU integrating dual-operation flash memories, together with a CAN controller, all within a LQFP-48 compact package.

CAN, Controller Area Network, is now the prevailing global standard for LAN systems installed in automobiles. The trend began in Europe, the first region in the world to adopt the CAN controller-mounted microcontrollers, and now FUJITSU is taking the lead in the industry by offering diversified lineups of CAN microcontrollers as solutions for the control of safety and amenity functions in automobiles. The Company has just succeeded in offering the world first microcontrollers mounted with flash memories that allow simultaneous execution of read/write operations. With this innovation, the flash memories applied conventionally for readout purposes to change programs can now be used to store various types of data during power interruptions.

This innovation offers several other advantages, as well. By eliminating the need for EEPROM and related component

parts externally installed in the conventional designs, it substantially reduces cost. It also facilitates the new application of advanced controls for amenity, safety and communication, including learning and tracing of maintenance data with the use of large-density nonvolatile data memories.

The new series also offers an improved operating margin to
