TXC101 is a highly integrated single chip, multi-channel, low power, high data rate RF transmitter designed to operate in the unlicensed 315/433/868 and 915 MHz frequency bands. All critical RF and baseband functions are completely integrated in the chip, thus minimizing external component count and simplifying design-ins. Its small size with low power consumption makes it ideal for various short range radio applications. The TXC101 is a dual mode solution. In the Microcontroller mode, a generic 10MHz crystal and a low-cost microcontroller are the only requirements to create a complete Transmitter link. In the EEPROM mode, the TXC101 can function as a complete data transmitter with any SPI compatible EEPROM and does not need a micro controller. This makes it an ideal solution for a variety of simple short range radio applications.
