PIN CONFIGURATION

Pin Name

I/O

Description

A0 ~ A7

Code Address Pin Nos. 0 ~ 7

I

These eight tri-state pins are detected by PT2260 to

determine the encoded waveform bit 0 ~ bit 7. Each bit can

be set to “0”, “1”, or “f” (floating).

A8/D3 ~ A9/D2

I/PL*

Code Address Pin No. 8 ~ 9/Data Pin No. 3 ~ 2.

These two tri-state pins are detected by PT2260 to

determine the encoded waveform bit 8 ~ bit 9. When these

pins are used as address pins (as in PT2260-R2), they can

be set to “0”, “1”, or “f” (floating). When these pins are used

as data pins (as in PT2260-R4), they can only be set to “0”

or “1”.

D1, D0

I/PL

Data Pin No. 1/0.

These pins can only be set to “0” or “1”

OSC

Oscillator Pin

I A resistor connected between the Osc Pin and the Vcc

determines the fundamental frequency of the PT2260

DOUT

Data Output Pin.

O

The encoded waveform is serially outputted to this pin.

When PT2260 is not transmitting, DOUT outputs low (Vss)

voltage

Vcc

Positive Power Supply

Vss

Negative Power Supply

Note:

PL -- Pull-low Resistor is connected internally

PL* -- If those two pins are used as Data Pins (PT2260-R2), pull-low resistor is connected internally;

otherwise, no pull-low resistor is connected.
