description

The TRC1300 and TRC1315 are remote control serial-data encoders and decoders, and are members of the MARCSTAR^TM (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.

The TRC1300 and TRC1315 include several on-chip functions that normally require additional circuitry in a system design. These include an amplifier/comparator for detection and shaping of input signals as low as a few millivolts (typically when an RF link is used) and a variable-frequency internal oscillator to clock the transmitted or received security code.

The TRC1300 and TRC1315 MARCSTAR I E/D remote control encoder/decoders are characterized for operation over the temperature range of -40°C to 85°C and are available in 14-pin SOIC small-outline IC surface-mount (D) and 16-pin PDIP plastic dual in-line (N) packages.
