(Continued from preceding page.)
PLL: Supports dead band control (two types)
Reference frequencies: 1, 3, 5, 6.25, 12.5, and 25 kHz
Input frequencies: FM band: 10 to 230 MHz
AM band: 0.5 to 10 MHz
Input sensitivity: FM band: 35 mV rms (50 mV rms at
130 MHz or higher frequency)
AM band: 35 mV rms
External reset input: During CPU and PLL operation,
instruction execution is started
from location 0.
Built-in power-on reset circuit:
The CPU starts executing from location 0 when power
is first applied.
Static power-on function: Backup state clear function
using the BATT pin.
Halt mode: The controller operating clock is stopped.
Backup mode: The crystal oscillator is stopped.
Beep tone: 1.5 and 3.1 kHz
Built-in DC-DC converter:
Two systems (One system
can be used as an external circuit power supply by
providing an external transistor.)
Built-in low-pass filter amplifier: An external low-pass
filter amplifier circuit is no longer required in end
products.
Remaining power check function: The battery voltage
can be directly converted to a digital value by the A/D
converter.
Memory retention voltage: 0.9 V or higher.
