1. Description
The ATAM862-4 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 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.
