F2MC-16LX MB90378 Series
MB90F378/V378
■ DESCRIPTION
The MB90378 series is a line of general-purpose, 16-bit microcontrollers designed for those applications which
require high-speed real-time processing. The instruction set is designed to be optimized for controller applications
which inheriting the AT architecture of F2MC-16LX family and allow a wide range of control tasks to be processed
efficiently at high speed.
A built-in LPC interface, serial IRQ and PS/2 interface simplifies communication with host CPU and PS/2 devices
in computer system. Moreover, SMbus compliant I2C*2 and A/D converter implements the smart battery control.
With these features, the MB90378 series matches itself as keyboard controller with smart battery control.
While inheriting the AT architecture of the F2MC*1 family, the instruction set for the F2MC-16LX CPU core of the
MB90378 series incorporates additional instructions for high-level languages, supports extended addressing
modes, and contains enhanced multiplication and division instructions as well as a substantial collection of
improved bit manipulation instructions. In addition, the MB90378 series has an on-chip 32-bit accumulator which
enables processing of long-word data.
