* 1. Register D is changed.

2. The maximum value of input voltage is V

DD.

3. According to the difference of I/O pin structure, the setting of unused pins may be different.

4. In the 4519 Group, CNTR0 input is a timer 1 count source, and there is no underflow count function

of a watchdog timer.

5. In the 4519 Group, CNTR1 input is a timer 3 count source.

6. T4AB instruction becomes storing in R4L, not in timer 4

7. At reset, a watchdog function becomes valid and the function of a WRST instruction differs from the

4514 Group.

8. The supply voltage value is guaranteed accurately under the -20ºC to 85ºC condition.

9. The pin set as the analog input does not function as a port.

10. The cold start by program is possible.

11. The valid waveform of a wakeup signal can be selected.

12. State transition has changed by difference of an oscillation circuit.

Moreover, super low consumption current operation is possible by operating system by the on-

chip oscillator or quartz-crystal oscillation (32kHz).

The above table shows difference, some specifications and standards, not for all.

Moreover, fundamentally, the specification of each function is strengthened and register ability also differs.

Be sure to refer to the data sheet as for the latest detailed specification and an electrical characteristics.
