• Manufacturer Part Number: m65849bfp
• Description: Single Chip Surround Processor
• Manufacturer: Mitsumi Electronics, Corp.

This IC incorporates a current control type clock oscillator circuit in it, thus providing circuit
configuration just by connecting an Rc for current control pin 1 (MCLKCONT).
Fully internal clock supply prevents occurrence of undesired radiation without affecting any
external circuit.
The oscillator frequency fck is following.
Clock oscillator circuit
The Power On Reset
When the IC is supplied Vcc, the reset circuit is on and after about 120ms (Vcc=5V C 24 =47µF) the
reset circuit is off automatically.

The conditions are as follows.
Ex.)
The reset time depends on the external C of 24 pin and the time can be calculated
as follows.
