Description
The CMT2180/89A is a fully integrated, highly flexible, high
performance, SoC OOK/G(FSK) transmitter with an
embedded RISC microcontroller core for various 240 to
960 MHz wireless applications. It is part of the CMOSTEK
NextGenRF
TM
family, which includes a complete line of
transmitters, receivers and transceivers. The device
includes a 1024 words flash for programming the user’s
application, supports up to 4 push buttons to implement the
user defined functions. All the device features (such as
frequency, output power, WD
T
,
S
ecurity and etc.) and
programs can be burned into the device using the
CMOSTEK USB Programmer and RFPDK. Alternatively, in
stock products of 433.92/868.35 MHz are available for
immediate demands with no need of extra programming.
The CMT2180/89A uses a 1-pin crystal oscillator circuit
with the required crystal load capacitance integrated
on-chip to minimize the BOM counts. The device can
deliver up to +13 dBm output power and the PA output can
be either single-ended or differential. The device operates
from 2.3 V to 3.6
V
.
I
ts low power design enables superior
operation life for battery powered application. The
CMT2180/89A transmitter together with CMOSTEK
NextGenRF
TM
receiver enables a highly flexible, low cost
RF link.
