www.DataSheet4U.com Features Single Package Fully-integrated ROM Mask 4-bit Microcontroller with RF Transmitter Low Power Consumption in Sleep Mode (< 1 µA Typically) Maximum Output Power (10 dBm) with Low Supply Current (9.5 mA Typically) 2.0 V to 4.0 V Operation Voltage for Single Li-cell Power Supply -40°C to +125°C Operation Temperature SSO24 Package About Seven External Components Flash Controller for Application Program Available Description The ATAR862-3 is a single package triple-chip circuit. It combines an 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 310 MHz to 330 MHz with data rates up to 32 kbaud. For further frequency ranges such as 429 MHz to 439 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 ATAR862-3 Preliminary Figure 1.
