MB90V370 Datasheet | Fujitsu Semiconductor Limited

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 munication with host CPU and PS/2 devices in puter system. Moreover, SMbus pliant I2C- 2, parator 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) s PACKAGE 144-pin plastic LQFP (FPT-144P-M12) MB90370/375 Series (Continued) While inheriting the AT architecture of the F2MC- 1 family, the instruction set for the F2MC-16LX CPU core of the MB90370/375 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. - 1 : F2MC stands for FUJITSU Flexible Microcontroller and a registered trademark of FUJITSU LIMITED. - 2 : Purchase of Fujitsu I2C ponents conveys a license under the Philips I2C Patent Rights to use, these ponents in an I2C system, provided that the system conforms to the I2C Standard Specification as defined by Philips. .. s FEATURES - Clock - Embedded PLL clock multiplication circuit - Operating clock (PLL clock) can be selected from divided-by-2 of oscillation or one to four times 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...
