CMT2251AW-EQR 433.92 MHz QFN16 5,000 pcs
Descriptions
The CMT2251AW is a true single-chip, ultra low power and
high performance device that consists of an OOK RF
receiver, a data decoder and 1 PWM output pin for various
300 to 480 MHz wireless applications. The device
integrates a data decoder that is not only compatible with
the most common used packet format of 1527, 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 the
RFPDK. Alternatively, in stock products of 433.92 MHz are
available for immediate demands with no need of EEPROM
programming. When pairing the device to CMOSTEK
transmitter, 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 CMT2251AW
is part of the CMOSTEK NextGenRFTM family, together with
CMT215x transmitters, they enable ultra low cost, low
power consumption RF links.
