Remote Control Encoder

PT2260

PIN CONFIGURATION

Pin Name

I/O

Description

Pin No.

A0 ~ A7

I

Code Address Pin Nos. 0 ~ 7

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).

1 ~ 8

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”.

10 ~ 11

D1, D0

I/PL

Data Pin No. 1/0.

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

12, 13

OSC

I

Oscillator Pin

A resistor connected between the Osc Pin and the Vcc

determines the fundamental frequency of the PT2260

14

DOUT

O

Data Output Pin.

The encoded waveform is serially outputted to this pin.

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

voltage

15

Vcc

Positive Power Supply

16

Vss

Negative Power Supply

9

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.
