The device integrates a data encoder that is not only compatible with the most common used encoding format of 1527 and 2262, but also a more efficient, flexible and powerful format of 1920 designed by CMOSTEK. Up to 7 configurable push buttons are supported in multiple button SOP14 modes. When pairing the device to CMOSTEK receiver, t he synchronization ID can be programmed into both of the transmitter and receiver during the manufacturing phase, LED 1 14 XTAL or studied by the receiver from the transmitter remotely by end customers. An embedded EEPROM allows the RF and VDD 2 13 CLK encoder parameters to be programmed into the chip using GND 3 12 DATA the CMOSTEK USB Programmer and the RFPDK. 4 K1 RFO 11 Alternatively, in stock product of 433.92 MHz is available for immediate demands without the need of EEPROM K7 5 10 K2 programming. The CMT2150A is part of the CMOSTEK K6 6 9 K3 TM NextGenRF family, together with CMT225x series K5 7 8 K4 receivers, they enable ultra low cost, low power consumption RF links.
