Functional Description
The HT6P12 is a 24-bit decoder with a learning
function. It pairs with the HT6P20D (data
negative polarity output type) encoder for re-
mote control system applications. The decoder
can interface with HOLTEK’s EEPROM
(HT93LC46). It stores a maximum of 8 sets of
customer codes in the EEPROM, and contains
an option table which is written into the
EEPROM through HOLTEK’s tool.
