s DESCRIPTION
The MB90370/375 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*2, comparator for battery control and A/D converter imple-
ments the smart battery control. With these features, the MB90370/375 series matches itself as keyboard con-
troller with smart battery control.

s DIFFERENCES AMONG PRODUCTS
Memory size
In evaluation with an evaluation product, note the difference between the evaluation product and the product
actually used. The following items must be taken into consideration.
• The MB90V370 does not have an internal ROM, however, operations equivalent to chips with an internal ROM
can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of the
development tool.
• In the MB90V370, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH are
mapped to bank FF only. (This setting can be changed by the development tool configuration.)
• In the MB90372/F372, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH
are mapped to bank FF only.
