s DESCRIPTION
MB90455 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 system, inheriting the architecture of F2MC* family, employs additional instruction ready for high-level lan-
guages, expanded addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instruc-
tions. Furthermore, employment of 32-bit accumulator achieves processing of long-word data (32 bits).
The peripheral resources of MB90455 series include the following:
8/10-bit A/D converter, UART 1, 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer, input capture
0, 1, 2, 3 (ICU)).

s 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 multi-
plied PLL clock).

8/16-bit PPG timer
Number of channels: 2 (four 8-bit channels are available also)
PPG operation is allowed with four 8-bit channels or one 16-bit channel.
Outputting pulse wave of arbitrary cycle or arbitrary duty is allowed.
Count clock: 62.5 ns to 1 µs
(with 16 MHz machine clock)
Delay interrupt generator
module
Interrupt generator module for task switching. Used for Real-time OS.
DTP/External interrupt
Number of inputs: 4
Activated by rising edge, falling edge, “H” level or “L” level input.
External interrupt or expanded intelligent I/O service (EI2OS) is available.
8/10-bit A/D converter
Number of channels: 8
Resolution: Selectable 10-bit or 8-bit.
Conversion time: 6.125 µs (at 16-MHz machine clock, including sampling time)
Sequential conversion of two or more successive channels is allowed. (Setting
a maximum of 8 channels is allowed.)
Single conversion mode : Selected channel is converted only once.
Sequential conversion mode: Selected channel is converted repetitively.
Halt conversion mode
: Conversion of selected channel is stopped and
activated alternately.
UART 1
Number of channels: 1
Clock-synchronous transfer: 62.5 Kbps to 2 Mbps
Clock-asynchronous transfer: 9,615 bps to 500 Kbps
Communication is allowed by bi-directional serial communication function and
master/slave type connection.
