■ DESCRIPTION

MB90385 series devices are general-purpose high-performance 16-bit micro controllers designed for process control of consumer products, which require high-speed real-time processing. The devices of this series have the built-in full-CAN interface.

■ FEATURES

? Clock

? Built-in PLL clock frequency multiplication circuit

? Selection of machine clocks (PLL clocks) is allowed among frequency division by two on oscillation clock, and multiplication of 1 to 4 times of oscillation clock (for 4-MHz oscillation clock, 4 MHz to 16 MHz).

? Operation by sub-clock (8.192 kHz) is allowed.

? Minimum execution time of instruction: 62.5 ns (when operating with 4-MHz oscillation clock, and 4-time multiplied PLL clock).

? 16 Mbyte CPU memory space

? 24-bit internal addressing

? Instruction system best suited to controller

? Wide choice of data types (bit, byte, word, and long word)

? Wide choice of addressing modes (23 types)

? Enhanced multiply-divide instructions and RETI instructions

? Enhanced high-precision computing with 32-bit accumulator

? Instruction system compatible with high-level language (C language) and multitask

? Employing system stack pointer

? Enhanced various pointer indirect instructions

? Barrel shift instructions

? Increased processing speed

? 4-byte instruction queue

? Powerful interrupt function with 8 levels and 34 factors

? Automatic data transfer function independent of CPU

? Expanded intelligent I/O service function (EI2 OS): Maximum of 16 channels

? Low power consumption (standby) mode

? Sleep mode (a mode that halts CPU operating clock)

? Time-base timer mode (a mode that operates oscillation clock, sub clock, time-base timer and clock timer only)

? Clock mode (a mode that operates sub clock and clock timer only)

? Stop mode (a mode that stops oscillation clock and sub clock)

? CPU blocking operation mode

? Process

? CMOS technology

? I/O port

? General-purpose input/output port (CMOS output) :

MB90387, MB90F387 : 34 ports (including 4 high-current output ports)

MB90387S, MB90F387S : 36 ports (including 4 high-current output ports)

? Timer

? Time-base timer, clock timer, watchdog timer: 1 channel

? 8/16-bit PPG timer: 8-bit x 4 channels, or 16-bit x 2 channels

? 16-bit reload timer: 2 channels

? 16-bit input/output timer

- 16-bit free run timer: 1 channel

- 16-bit input capture: (ICU): 4 channels

Interrupt request is issued upon latching a count value of 16-bit free run timer by detection of an edge on pin input.

? CAN controller: 1 channel

? Compliant with Ver2.0A and Ver2.0B CAN specifications

? 8 built-in message buffers

? Transmission rate of 10 Kbps to 1 Mbps (by 16 MHz machine clock)

? CAN wake-up

? UART (SCI): 1 channel

? Equipped with full-duplex double buffer

? Clock-asynchronous or clock-synchronous serial transmission is available.

? DTP/External interrupt: 4 channels, CAN wakeup: 1channel

? Module for activation of expanded intelligent I/O service (EI2OS), and generation of external interrupt.

? Delay interrupt generator module

? Generates interrupt request for task switching.

? 8/10-bit A/D converter: 8 channels

? Resolution is selectable between 8-bit and 10-bit.

? Activation by external trigger input is allowed.

? Conversion time: 6.125 μs (at 16-MHz machine clock, including sampling time)

? Program patch function

? Address matching detection for 2 address pointers.
