FUNCTION DESCRIPTION
13
The M65850P incorporates a current control type clock
oscillator circuit in it, thus providing circuit configuration just by
connecting a resistor for current control to pin 13 ( FP:pin 14 )
CLOCK.
Fully internal clock supply prevents occurrence of undesired
radiation without affecting any external circuit.
The oscillator frequency is:
fck = 1 MHz. ( Rc=120k
)
The resistor for current control can be calculated using the
following equation.
Rc
K is the coefficient, and changes according to clock frequency
,as shown below.

The delay time can be calculated by the equation :
Td=8N / fck ( N=the number of memory bits=20480 )
When fck=1MHz ( fs=125kHz), Td can be set at 164ms.
Reference
The M65850P/FP adopts ADM ( Adaptive Delta Modulation ) system in A-D,D-A
converters.
The sampling frequency can be calculated by the following equation :
fs=clock frequency / 8 ( Hz )
For clock frequency ( fck )=1MHz, the calculated sampling frequency is :
fs=1MHz / 8 =125kHz
