F2MC-16LX MB90370 Series
MB90372/F372/V370
Version 1.3
■ DESCRIPTION
The MB90370 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 series 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, comparator for battery control and A/D converter implements
the smart battery control. With these features, the MB90370 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
MB90370 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 MB90370 has an on-chip 32-bit accumulator which
enables processing of long-word data.
Notes: *1: F2MC stands for FUJITSU Flexible Microcontroller, a registered trademark of FUJITSU LIMITED.
*2: Purchase of Fujitsu I2C components conveys a license under the Philips I2C Patent Rights to use these
components in an I2C system, provided that the system conforms to the I2C Standard Specification as
defined by Philips.
■ FEATURES

the oscillation (at oscillation of 4 MHz to 16 MHz)
• Minimum instruction execution time of 62.5 ns (at oscillation of 4 MHz, four times the PLL
clock, operation at VCC of 3.3 V)
● CPU addressing space of 16 Mbytes
• Internal 24-bit addressing
● Instruction set optimized for controller applications
• Rich data types (bit, byte, word, long word)
• Rich addressing mode (23 types)
