Complies with Directive 2002/95/EC (RoHS)
Product Overview
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 Micro controller 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.
