Description
The ATAM862-4 is a single package dual-chip circuit. It bines 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 transmitting frequency range of 429 MHz to 439 MHz with data rates up to 32 kbaud Manchester coded. For further frequency ranges such as 310 MHz to 330 MHz and 868 MHz to 928 MHz separate datasheets are available. The device contains a flash microcontroller.
