It is part of the CMOSTEK TM NextGenRF family, which includes a complete line of transmitters, receivers and transceivers. The device SOP14 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 VDD 1 14 XTAL programs can be burned into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in GND 2 13 GND stock products of 433.92/868.35 MHz are available for PAP 3 12 DATA immediate demands with no need of extra programming. The CMT2180/89AW uses a 1-pin crystal oscillator circuit PAN 4 11 VDD w ith the required crystal load capacitance integrated CLK 5 10 GND on-chip to minimize the BOM counts. The device can deliver up to +13 dBm output power and the PA output can K3/VTG 6 9 K0/DATA2 be either single-ended or differential. The device operates K2 7 8 K1/CLK2 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 CMT2180/89AW TM NextGenRF receiver enables a highly flexible, low cost RF link.
