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 implements the smart battery control. With these features, the MB90370/375 series matches itself as keyboard controller with smart battery control. (Continued)
