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
