The OM6XXX is a power-optimized true system-on-chip (SOC) solution for both Bluetooth low energy and proprietary 2.4GHz applications. It integrates a high performance and low power RF transceiver with Bluetooth base band and rich peripheral IO extension. OM6XXX also integrates power management unit (PMU) to provide high-efficient power management. It targets 2.4GHz Bluetooth low energy systems, proprietary 2.4GHz systems, Human-Interface Devices (keyboard, mouse, and remote control), sports and leisure equipment, mobile phone accessories and consumer electronics.

OM6XXX on-chip Bluetooth system compliant with version 5.3.

The chip integrates up to 64MHz high-performance MCU, DMA, GPIO, SPI, UART, Timer, Watchdog, supports 32MHz external crystal, integrates multi-purpose max 12-bit ADC.

The OM6XXX integrates on chip 80K SRAM, 256-bit EFUSE and supports user defined IDE system on chip SFLASH MCU development and JTAG software upgrade.
