8-bit timer/counter:
2 channels (can be used as 1 channel of 16-bit timer)
7-bit basic interval timer:
1 channel (can be used as watchdog timer)

1 channel (3-wire)
Multiple interrupt by hardware (3 levels MAX.)
External interrupt (INT): 1
Rising edge, falling edge, or both rising and falling
edges selectable for detection.

28-pin plastic shrink DIP (400 mil)
28-pin plastic SOP (375 mil)
Quality grade is "standard" and not (A1).
Operating temperature range: T
a
= –40 to +85 C
Note
The INT pin is used as an input pin (sense input) when the external interrupt function is not used.
The status of this pin is read by using the INT flag of a control register, not by a port register.
Caution
The PROM version is functionally compatible with the mask ROM versions but its internal
circuit and part of the electrical characteristics are different from those of the mask ROM
versions. To replace the PROM version with a mask ROM version, thoroughly conduct
application evaluation by using a sample of the mask ROM version.
