The 16MHz crystal oscillator generates the SKY76303 IC fundamental system clock used as the basis for all RF and
digital audio clocks.
The 4Mb flash memory chip is used to store the module’s application firmware. The SKY76303 is able to boot
from internal ROM upon first power up, which enables programming the flash chip with the application firmware
through USB. In addition, Over-the-air Firmware upgrade capability can be enabled through the application
firmware.
The module can be controlled from an external host device via the I2C Slave or the SPI Slave data interfaces. The
I2C master port allows the module to control other system audio devices such as a sub-woofer amplifier system
without having to add another MCU to the product design.
Up to 10 additional GPIOs are available on the ATM510 module (not including I2C and I2S signals) for
implementing different UI features on the target application.
The ATM510 module is available in two variations; digital input transmitter or digital output receiver.
* ATM510 module has two PCB printed antenna for RX diversity. This module is not supporting for RF operation of
MIMO mode. So those antenna are not used as MIMO mode.
