description
The TRC1300 and TRC1315 are remote control serial-data encoders and decoders, and are members of the MARCSTARTM (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.

description (continued)
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.

Terminal Functions
TERMINAL NAME CONF NO. D 2 N 2 I Device configuration select. When CONF is held at a high logic level, the device assumes the encoder mode. CONF is internally pulled up, and no connection to CONF is required for the encoder mode of operation. When CONF is held at a low logic level at power up, the device assumes the decoder mode. Note that this terminal is read only at device power up; CONF must be tied to GND before VCC is applied to select the decoder mode. Serial data input/output. In the decoder mode, DIN/DOUT becomes an input to receive serial data from up to four remote encoders. In the learn mode, DIN/DOUT becomes an input to learn code from up to four remote encoders. In the encoder mode, DIN/DOUT becomes an output for the encoded data. DIN/DOUT is clocked by the internal variable oscillator. Analog and logic ground O Status indicator. The LED terminal goes low, causing an LED connected from VCC (anode) to the LED terminal (cathode) through a current-limiting resistor to light, indicating the following conditions: · · Encoder mode. When the device is configured as an encoder, the LED terminal is active during the transmission of data (including the blank time between frames). Program mode (encoder). When the device is configured as an encoder and placed in the program mode, the LED terminal is active until the device has generated and stored a new 40-bit security code. Learn mode (decoder). When the device is configured as a decoder and placed in the program mode, the LED terminal is active until the device has successfully stored 40 bits of security code received from an encoder through terminal DIN/DOUT. Test mode. When the device is placed in the self-test mode, the results are indicated by flashing the LED connected to the LED terminal. I/O DESCRIPTION

Internal oscillator frequency control. A capacitor connected from OSCC to GND and a resistor connected from OSCR to OSCC determine the frequency of the internal oscillator. Internal oscillator frequency control. A resistor connected from OSCR to OSCC and a capacitor connected from OSCC to GND determine the frequency of the internal oscillator. Programming enable. When PROG is held at a logic-high, device enters the programming mode. In the encoder mode, a new 40-bit security code is generated and stored in EEPROM. In the decoder mode, the device enters a learn cycle that continues until it has successfully received 40 bits of code from an encoder and stored them in EEPROM. PROG is internally pulled down and debounced. Test mode select. When TEST is momentarily taken high, the device enters a self-test mode with the results of the self-test mode displayed by flashing the LED connected to the LED terminal. TEST is internally pulled down. Not used. Power supply input for the TRC1315 only. The voltage range for VCC is 4.5 V to 15 V. A 0.1-µF bypass capacitor should be connected from VCC to GND. Power supply input for the TRC1300 only. The voltage range for VCC/CAP is 2.7 V to 6 V. A 0.1-µF bypass capacitor should be connected from VCC/CAP to GND. Regulated voltage output for the TRC1315 only. This terminal provides a regulated 4.5 V to 5.5 V output. A 1-µF and a 0.1-µF bypass capacitor should be connected from VCC/CAP to GND.
