MB90488B General Description

■ DESCRIPTIONThe MB90480/485 series is a 16-bit general-purpose FUJITSU microcontroller designed for process control in consumer devices and other applications requiring high-speed real-time processing.The F2MC-16LX CPU core instruction set retains the AT architecture of the F2MC*1 family, with additional instructions for high-level languages, expanded addressing mode, enhanced multiply-drive instructions, and complete bit processing. In addition, a 32-bit accumulator is provided to enable long-word processing.■ FEATURES• ClockMinimum instruction execution time: 40.0 ns/6.25 MHz base frequency multiplied ×4 (25 MHz internal operating frequency/3.3 V ± 0.3 V) 62.5 ns/4 MHz base frequency multiplied × 4 (16 MHz internal operating frequency/3.0 V ± 0.3 V) PLL clock multiplier• Maximum memory space: 16 Mbyte • Instruction set optimized for controller applications Supported data types (bit, byte, word, or long word) Typical addressing modes (23 types) Enhanced signed multiplication/division instruction and RETI instruction functions 32-bit accumulator for enhanced high-precision calculation• Instruction set designed for high-level language (C) and multi-task operations System stack pointer adopted Instruction set compatibility and barrel shift instructions• Non-multiplex bus/multiplex bus compatible• Enhanced execution speed 4 byte instruction queue• Enhanced interrupt functions 8 levels setting with programmable priority, 8 external interrupts• Data transmission function (µDMA) Up to 16 channels• Embedded ROM Flash versions : 192 KB, 256 KB, MASK versions : 192 KB• Embedded RAM Flash versions : 4 KB, 6 KB, 10 KB, MASK versions : 10 KB• General purpose ports Up to 84 ports (Except MB90V480 : Includes 16 ports with input pull-up resistance, 16 ports with output open drain settings)• A/D converter 8-channel RC sequential comparison type (10-bit resolution, 3.68 µs conversion time (at 25 MHz) )• I2C interface (MB90485 series only) : 1channel, P76/P77 Nch OD pin (without Pch) Do not apply high voltage in excess of recommended operating ranges to the Nch open drain pin (with Pch) in MB90V485.• µPG (MB90485 series only) : 1 channel• UART: 1 channel• I/O expanded serial interface (SIO) : 2 channels• 8/16-bit PPG: 3 channels (with 8-bit × 6 channel/16-bit × 3 channel mode switching function)• 8/16-bit up/down timer: 1 channel (with 8-bit × 2 channel/16-bit × 1-channel mode switching function)• PWC (MB90485 series only) : 3 channels (Capable of compare the inputs to two of the three)• 3 V/5 V I/F pin (MB90485 series only) P20 to P27, P30 to P37, P40 to P47, P70 to P77• 16-bit reload timer: 1 channel• 16-bit I/O timer: 2-channel input capture, 6-channel output compare, 1-channel free run timer• On chip dual clock generator system• Low-power consumption mode With stop mode, sleep mode, CPU intermittent operation mode, watch mode, timebase timer mode• Packages: QFP 100/LQFP 100• Process: CMOS technology• Power supply voltage: 3 V, single source (some ports can be operated by 5 V power supply at MB90485 series)
