Overview: ATA8710
Sub-GHz ASK/FSK RF Transmitter with Integrated MCU and 20 Kbytes Flash Program Memory Introduction
The ATA8710 is a highly integrated, low-power UHF ASK/FSK RF transmitter with an integrated AVR® microcontroller.
The ATA8710 is partitioned into three sections: an RF front-end, digital baseband and the low-power 8-bit AVR microcontroller. The product is designed for the ISM frequency bands from 310 MHz to 318 MHz, 418 MHz to 477 MHz, and 836 MHz to 956 MHz. The external part count is kept to a minimum due to the very high level of integration in this device. By combining outstanding RF performance with highly sophisticated baseband signal processing, robust wireless communication can be easily achieved. The transmit path uses a closed-loop fractional-N modulator with Gauss shaping and preemphasis functionality for high data rates.
The ATA8710 implements a flexible service configuration concept and supports up to 15 channels. These channels are grouped into five service configurations with three channels each. Three of the five service configurations are stored in EEPROM. Two service configurations are in the SRAM to allow on-the-fly modifications during IDLEMode via SPI commands or application software, which is in Flash. The 1024-byte EEPROM stores the transmitter configuration. The SPI interface enables external control and device reconfiguration.
Use the internal microcontroller with 20 Kbytes Flash program memory to add custom extensions to the embedded firmware. In addition, the debugWIRE and ISP interfaces are available for programming purposes.
