Description
The ATAR862-4 is a single package triple-chip circuit. It combines a UHF ASK/FSK
transmitter with a 4-bit microcontroller and a 512-bit EEPROM. It supports highly inte-
grated 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 ROM mask version microcontroller and an additional data
EEPROM.
