Description
The T48C862-R4 is a single package dual-chip circuit. It combines a UHF ASK/FSK
transmitter with a 4-bit microcontroller. It supports highly integrated solutions in car
access and tire pressure monitoring applications, as well as manifold applications in
the industrial and consumer segment. It is available for the frequency range of
429 MHz to 439 MHz with data rates up to 32 kbaud.
For further frequency ranges such as 310 MHz to 330 MHz and 868 MHz to 928 MHz
separate data sheets are available.
The device contains a flash microcontroller.
