MC-16LX MB90385 Series
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.
The system, inheriting the architecture of F
2
MC family, employs additional instruction ready for high-level languages, expanded
addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instructions. Furthermore, employment of 32-
bit accumulator achieves processing of long-word data (32 bits).
The peripheral resources of MB90385 series include the following:
8/10-bit A/D converter, UART (SCI), 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU)),
and CAN controller.
Features
Clock

Time-base timer mode (a mode that operates oscillation clock,
sub clock, time-base timer and watch timer only)
Watch mode (a mode that operates sub clock and watch timer
only)
Stop mode (a mode that stops oscillation clock and sub clock)
CPU blocking operation mode
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. (MB90387,
MB90F387)
Minimum execution time of instruction: 62.5 ns (when operating
with 4-MHz oscillation clock, and 4-time multiplied PLL clock).
