CMT2250AW CMT2250AW 300 – 480 MHz OOK Receiver with Decoder Features  Embedded EEPROM  Very Easy Development with RFPDK  All Features Programmable  3-wire SPI Interface for EEPROM Programming  Frequency Range: 300 to 480 MHz  Symbol Rate: 0.1 to 40 ksps  Sensitivity: -114 dBm at 1 ksps, 0.1% BER  Stand-Alone, No External MCU Control Required  Embedded 1920, 1527 and 2262 Data Decoder  4 Data Outputs  Configurable Duty-Cycle Receive Mode  Low Power Consumption: 3.8 mA  Low Sleep Current  60 nA When Sleep Timer Off  440 nA When Sleep Timer On  ID Study, Factory Code Supported  RoHS Compliant  Available in QFN16( 3x3), DIP16 and SOP16 Packages Descriptions The CMT2250AW is a true single-chip, ultra low power and high performance device that consists of an OOK RF receiver, a data decoder and 4 data output pins for various 300 to 480 MHz wireless applications. The device integrates a data decoder 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. The device delivers sensitivity up to -114 dBm while consuming only 3.8 mA current when it is always on. An embedded EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock product of 433.92 MHz is available for immediate demands with no need of EEPROM programming. When pairing the device to CMOSTEK transmitters, the synchronization ID can be programmed into both of the transmitter and receiver during the manufacturing phase, or studied by the receiver from the transmitter remotely by end customers. The CMT2250AW is part of the CMOSTEK NextGenRFTM family, together with CMT215x series transmitters, they enable ultra low cost, low power consumption RF links.
