16-bit Microcontrollers
F2MC-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 F2MC 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
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).
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 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
Process
CMOS technology
I/O Port
General-purpose input/output port (CMOS output):
MB90387, MB90F387: 34 ports (including 4 high-current out-
put ports)
MB90387S, MB90F387S: 36 ports (including 4 high-current
output ports)
Timer
Time-base timer, watch 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.
