It combines a UHF ASK/FSK transmitter with a 4-bit microcontroller and a 512-bit EEPROM. 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 ROM mask version microcontroller and an additional data EEPROM. Microcontroller with UHF ASK/FSK Transmitter ATAR862-4 Preliminary Figure 1.
