Description
The CMT2180/89AW 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, WDT, Security 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 CMT2180/89AW 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. Its low power design enables superior
operation life for battery powered application. The
CMT2180/89AW transmitter together with CMOSTEK
NextGenRF
TM
receiver enables a highly flexible, low cost
RF link.

Notes:
1. Connector J1 is used only for chip
programming.
2. D1 is used to isolate the 15V high voltage
at VTG during chip programming. If user
does not need to program the chip, D1
can be removed, but pulling VTG up to
VDD by R1 is always required.
