68HC908JB8PB/D
Improves reliability by resetting the
MCU when voltage drops below trip
point
Integration reduces system cost
LOW-VOLTAGE INHIBIT
High sink/source capability on all I/O
pins
25 mA sink capability on two I/O pins
Keyboard scan with selectable
interrupts on eight I/O pins
High-current capable I/O allows direct
drive of LED and other circuits to
eliminate external drivers and reduce
system costs
Keyboard scan with programmable
pullups eliminate external glue logic
when interfacing to simple keypads
UP TO 37 BIDIRECTIONAL INPUT/OUTPUT (I/O) LINES
