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 NextGenRFTM 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 NextGenRFTM receiver enables a highly flexible, low cost RF link.

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.
