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. *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. .co ■ PACKAGE m 144-pin plastic LQFP ata Sh eet 4U (FPT-144P-M12) ww w.D www.DataSheet4U.com MB90378 Series ■ FEATURES • Clock • Embedded PLL clock multiplication circuit • Operating clock (PLL clock) can selected from divided-by-2 of oscillation or one to four times the oscillation (at oscillation of 4 MHz to 20 MHz) • Minimum instruction execution time of 50 ns (at oscillation of 5 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) • High code efficiency • Enhanced precision calculation realized by the 32-bit accumulator • Instruction set designed for high level language (C) and multi-task operations • Adoption of system stack pointer • Enhanced pointer indirect instructions • Barrel shift instructions • Program patch function (2 address pointer) • Improved execution speed 4-byte instruction queue • Powerful interrupt function • Priority level programmable : 8 levels • 32 factors of stronger interrupt function • Automatic data transmission function independent of CPU operation • Extended intelligent I/O service function (EI2OS) • Maximum 16 channels • Low-power consumption (standby) mode • Sleep mode (mode in which CPU operating clock is stopped) • Timebase timer mode (mode in which operations other than timebase timer and watch timer are stopped) • Stop mode (mode in which all oscillations are stopped) • CPU intermittent operation mode • Watch mode • Dual operation flash Upper and lower banks of flash memory can be used to execute erase/program and read operation concurrently (MB90F378) • Package LQFP-144 (FPT-144P-M12 : 0.4 mm pitch) ww w.D 2 ata Sh • Process CMOS technology eet 4U .co m www.DataSheet4U.com MB90378 Series ■ PRODUCT LINEUP Part number Parameter Classification ROM size RAM size MB90F378 Flash type ROM 128 Kbytes (112 Kbytes + 16 Kbytes) Dual operation 6 Kbytes Number of instruction : 351 Minimum execution time : 50 ns/5 MHz (PLL x 4) Addressing mode : 23 Data bit length : 1, 8, 16 bits Maximum memory space : 16 Mbytes I/O port (Nch) I/O port (CMOS) I/O port (CMOS with pull-up control) Total : 25 : 68 : 32 : 125 MB90V378 ⎯ ⎯ 15.6 Kbytes CPU function I/O port 16-bit reload timer 8/16-bit PPG timer 16-bit PPG timer Bit decoder Parity generator PS/2 interface Reload timer : 6 channels Reload mode, single-shot mode or event count mode selectable PPG timer : 2 channels (8-bit mode, 4 channels) PPG timer : 3 channels PWM mode or single-shot mode selectable Bit decoder : 1 channel Parity generator : 1 channel Selectable odd/even parity PS/2 interface : 3 channels 4 selectable sampling clocks LPC bus interface Universal peripheral Interface GA20 output control Data buffer array : 1 channel : 4 channels : for UPI ch 0 only : 80 bytes .co m LPC interface Serial IRQ controller Serial IRQ request : 6 channels LPC clock monitor/control With full-duplex double buffer (variable data length) Clock asynchronized or clock synchronized transmission (with start and stop bits) can be selectively used I2C (SMbus compliant) : 1 channel Support I2C bus of PHILIPS and the SMbus proposed by Intel I2C bus Selectable packet error check Timeout detecti.
