(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.

• Package: SQFP-64 (0.5 mm lead pitch)
