s/4.2 MHz
Ports
Dedicated output port (N-ch open drain)
: 4 port pins (4 port pins also serve as
resource pins) (MB89190A series),
6 port pins (MB89190 series)
General-purpose I/O port (CMOS)
: 16 port pins (8 port pins also serve as
resource pins)
Total count of port pins
: 20 or 22 port pins
time-base timer
20 bits
Interrupt cycle (1.95 ms, 7.80 ms, 62.42 ms, 499.32 ms)
Watchdog timer
Reset generation cycle (499.3 ms minimum)
8-/16-bit
timer/counter
8-bit timer/counter operation 2-channel (independent operating clock of timer 1 and
timer 2), or 16-bit timer/counter operation (cycle of operating clock: 1.9 s to 487.6 s)
When timer 1 or the 16-bit counter operates, external-clock-based event counter or
square wave output are possible.
serial I/O
8 bits long
LSB first/MSB first selectable
Transfer clock (External or Internal 1.9
s, 7.6 s, or 30.5 s)
Buzzer output
Output frequency (1025 Hz, 2051 Hz, 4102 Hz, 8203 Hz)
External interrupt
3 channels (interrupt vector, request flag, and request output permission)
Edge selection possible (rising, falling, and both-edge modes selectable)
Can also be used for clearing stop/sleep mode (edge detection in stop mode as well)
External interrupt
2 (wakeup)
8-input 1-channel ("L" level interrupt and input permission independent)
Can also be used for clearing stop/sleep mode (level detection in stop mode as well)
A/D converter
(MB89190A
Series only)
8-bit accuracy
× 8 channels
A/D conversion function (conversion time: 41.9
s)
Sense function (comparison time: 11.4 s)
Continuous starting can be performed using the external clock or internal clock.
A reference voltage input is provided (AVR).

A 6-bit counter is built-in.
The pulse width and the cycle can be selected using a program.
(cycle: 0.48 to 1950 s, H-width: 0 to 1950 s)
This can also be used as a 6-bit PPG.
Note: The clock cycle, conversion time, etc., values are obtained at 4.2-MHz operation.
