Item
µPD178023
µPD178024
Frequency counter
Frequency measurement
• AMIFC pin: For 450-kHz counting
• FMIFC pin: For 450-kHz/10.7-MHz counting
Reset
• 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)
Supply voltage
• VDD = 4.5 to 5.5 V (during CPU, PLL operation)
•VDD = 3.5 to 5.5 V (during CPU operation)
Package
• 80-pin plastic QFP (14
× 20)
• 80-pin plastic QFP (14
× 14)
Note
These voltages are the maximum values. In practice, the chip may be reset at voltages lower than these.
