Programming timing of the HT6P20D (B0~B3=1010)
HT6P20

Functional Description
Programming
The HT6P20 is a one time programmable encod-
ing integrated circuit. The programmable codes
consist of 4-bit control codes and 24-bit address
codes. Before using the device, first program the
internal 4 control bits and 24 address bits. Then,
to program the address and control codes, con-
nect the PGM pin to VSS, allowing the SIO pin to
receive control and address codes from the con-
tinuously transmitting programming kit. The
control codes (B0~B3) and address timing are re-
spectively shown on the Table and the Figure for
Programming Timing. In the programming pro-
cess, the mode bit (B0) has to be programmed
first. The 0/2/4/8 data number is selected by the
address along with the data format bits (B1,B2).
The HT6P20, in addition, provides a polarity bit
(B3) to select the polarity of the output data.
Various packages of the HT6P20 offer program-
mable combinations of address/data to meet
various application needs.

The HT6P20A/D can be programmed by the
SIO pins. The HT6P20B, on the other hand, is
programmed for 2-data and positive polarity
application.
