The following is the circuit diagram of the **ATA5830 application circuit**.
The **ATA5830** is a highly integrated, low-power UHF ASK/FSK RF transceiver designed for general-purpose use. It combines the RF section, digital baseband, and an AVR microcontroller core in a single chip. The core is a low-power CMOS 8-bit MCU with an enhanced RISC architecture, making it ideal for a wide range of wireless applications. Operating in the ISM band, it supports frequency ranges of 310MHz–318MHz, 418MHz–477MHz, and 836MHz–928MHz, with data rates from 0.5k to 20kBit/s using Manchester encoding. It can operate at voltages as low as 1.9V–3.6V or 4.5V–5.5V, and works within a temperature range of –40°C to +105°C. This makes it suitable for applications such as RKE (Remote Keyless Entry), TPMS (Tire Pressure Monitoring Systems), remote start systems, and other intelligent RF solutions.
