Functions

Frequency measurement

• AMIFC pin: For 450-kHz counting

• FMIFC pin: For 450-kHz/10.7-MHz counting

• HALT mode

• STOP mode

• Reset by RESET pin

• Internal reset by watchdog timer

• Reset by power-ON clear circuit

• Detection of less than 4.5 VNote (Reset does not occur, however.)

• Detection of less than 3.5 VNote (during CPU operation)

• Detection of less than 2.3 VNote (in STOP mode)

• VDD = 4.5 to 5.5 V (during CPU, PLL operation)

• VDD = 3.5 to 5.5 V (during CPU operation)

100-pin plastic QFP (14 × 20)

(2/2)

Note These voltages are the maximum values. In practice, the chip may be reset at voltages lower than these.
