description
The TRC1300 and TRC1315 are remote control serial-data encoders and decoders, and are members of the
MARCSTAR (Multichannel Advanced Remote Control Serial Transmitter and Receiver) family of remote
control serial-data devices. Each can be configured to perform as either the encoder or the decoder in a remote
control system. The TRC1300 and TRC1315 are designed for use in high-volume remote control products such
as automobile and home security systems, consumer electronics, electronic keys, and remote keyless entry
applications. They are low-power devices and are well suited to battery operation with a supply voltage of 2.7 V
to 6 V for the TRC1300 and 2.7 V to 15 V for the TRC1315.
Four independent encoder inputs/decoder outputs allow for control of up to 15 functions. Forty bits of hopping
code provide high security, more than one trillion possible combinations, so that the same code will never be
used twice by a MARCSTAR device over several lifetimes of a typical system. The MARCSTAR devices are
self-programming with internal charge-pump programming circuitry. A smart decoder design learns up to four
different encoders, all in a high-security hopping-code format.
