CMT2150LW
315/433/868/915 MHz Single-chip OOK Transmitter with Encoder
Description
As a highly flexible, ultra-low power and encoder-equipped OOK RF single-chip transmitter, the CMT2150LW is ideal for wireless applications with the frequency range of 240-480 MHz. The chip is fully compatible with the most commonly used encoding formats such as 527 and 1527. It supports 3 independent keys or up to 6 combination keys with no need for diode isolation between combined keys. In addition, the key value of each key can be configured separately. When shipped from the factory, the chip applies the 1527 encoding mode with incremental ID sequence by default. The CMT2150LW is configured to operate at 433.92 MHz. Users can operate the visual UI
interface RFPDK provided by CMOSTEK and the matching programming tool to configure the customized parameters into the EEPROM inside the chip to fulfill differentiated
applications. As part of the CMOSTEK NextGenRFTM product family, the CMT2150LW, cooperating with the CMT221x transmission chips, can help users fulfill low cost, low power and high performance applications excellently.
