Description

1~8

A0~A7

I

Code Address Pin Nos.0~7

These eight tri-state pins ate detected by SC5260 to determine the

encoded waveform bit0~bit7. Each bit can be set to “0”, “1”, or

“f”(floating).

10~11

A8/D3~A9/D2

I/PL*

Code Address pin Nos.8~9/Data Pin Nos.3~2.

These two tri-state pins are detected by SC5260 to determine the

encoded waveform bit8~bit9. When these pins ate used as address

pins (as in SC5260-R2), they can be set to “0”, “1”, or “f” (floating).

When these pins are used as data pins (as in SC5260-R4), they can

only be set to “0” or “1”.

12~13

D1, D0

I/PL

Data Pin Nos. 1~0. These pins can only be set to “0” or “1”.

14

OSC

I

Oscillator Pin A resistor connected between the OSC Pin and the VCC

determines the fundamental frequency of the SC5260.

15

DOUT

O

Data Output Pin. The encoded waveform is serially outputted to this

pin. When SC5260 is not transmitting, DOUT outputs low (VSS)

voltage.

Note: PL -- Pull-low Resistor is connected internally

PL* -- If those two pins are used as Data Pins (SC5260-R2), pull-low resistor is connected internally;

otherwise, no pull-low resistor is connected.
