2
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): 34 ports(MB90F455/F456/F457, MB90455/456/457) (in-
cluding 4 high-current output ports) (When sub clock is not used, 36 ports(MB90F455S/F456S/F457S,
MB90455S/456S/457S))
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.
UART 1: 1 channel
Equipped with full-duplex double buffer
Clock-asynchronous or clock-synchronous serial transmission is available
