Descriptions
The CMT2213AW is an ultra low power, high performance,
low-cost (G)FSK/OOK stand-alone RF receiver for various
300 to 480 MHz wireless applications. It is part of the
CMOSTEK
NextGenRF
TM
family,
which
includes
a
complete line of transmitters, receivers and transceivers. 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
VCON
VCOP
QFN16 (3
X
3)
stock products of 433.92 MHz is available for immediate
demands with no need of EEPROM programming. The
CMT2213AW operates from a supply voltage of 1.8 V to 3.6
V, when it is always on, it consumes only 4.3 mA current
while achieving -111 dBm receiving sensitivity. It consumes
even less power when working in duty-cycle operation
mode via the built-in sleep timer. The device provides
demodulated data, power-on reset output as well as a
system clock output for use by an external microcontroller
or decoder. The CMT2213AW receiver together with the
CMT2113AW transmitter enables an ultra low cost RF link.

Notes:
[1]. Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
[2]. The CMT2213AW is high-performance RF integrated circuits with VCON/P pins having an ESD rating < 2 kV HBM.
Handling and assembly of this device should only be done at ESD-protected workstations.
