General Description  
The HT6P20 is a CMOS LSI encoder designed for re-  
mote control system applications. It encodes 24 bits of  
information and then serially transmits it via the DOUT  
pin upon receipt of transmission enable (DATA pins:  
D0~D7) signals. The combination of address and data  
bits of the HT6P20 is designed using one time program-  
mable process. In addition, the chip offers various pack-  
aging for flexible combination of programmable  
address/data so as to meet various applications. Its pro-  
grammable address/data is transmitted together with  
the anti-code bits via RF or infrared transmission me-  
dium upon receipt of a trigger signal.

Note: The customer code and control code have been programmed into HT6P20A/B/D by Holtek¢s factory process.  
The blank device HT6P20 is not programmed, it can be programmed by Holtek¢s programming kit.  
The 8-pin blank device only allows programming as HT6P20A type and the 16-pin blank device allows pro-  
gramming as HT6P20D type.

Functional Description  
Programming  
Table 1: Control code  
·
Mode control (B0)  
The HT6P20 is a one time programmable encoding inte-  
grated 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 ad-  
dress bits. Then, to program the address and control  
codes, connect the PGM pin to VSS, allowing the SIO pin  
to receive control and address codes from the continu-  
ously transmitting programming kit. The control codes  
(B0~B3) and address timing are respectively shown on  
the Table and the Figure for Programming Timing. In the  
programming process, the mode bit (B0) has to be pro-  
grammed 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.

HT6P20 Series  
Normal operation  
The HT6P20 encodes and transmits address/data to a decoder upon receipt of a trigger signal. The address codes of  
the HT6P20A are always transmitted as long as power (VDD) is supplied. The transmission function of the HT6P20B/D  
is enabled by the D0~D7 pins (active low). The following is the transmission timing of the HT6P20:

A complete code word for the HT6P20D  
The HT6P20A/B/D detects the logic state of the internal programmed address and the external data pins, and then trans-  
mits the detected information during the code period. Each address/data bit can be set to one of the following two logic  
states:
