The OM6621Dx is a power-optimized true system-on-chip (SOC) solution for both Bluetooth low energy and proprietary 2.4-GHz applications. It integrates a high performance and low power RF transceiver with Bluetooth base band and rich peripheral IO extension.OM6621Dx also integrates a power management to provide high-efficient power management. It targets 2.4-GHz Bluetooth low energy systems, proprietary
2.4-GHz systems,Human-Interface Devices (keyboard, mouse, and remote control),sports and leisure equipment, mobile phone accessories and consumer electronics.
OM6621Dx on-chip Bluetooth system compliant with version 5.0.
The chip integrates up to 64MHz high-performance MCU, DMA, GPIO, SPI, UART,TIMER, watch dog, supports 32MHz external crystal, integrates multi-purpose 10bit ADC.
The OM6621Dx integrates on chip 24KB ROM, 24K SRAM, 16K OTP and supports user defined IDE system on chip SFLASH MCU development and JTAG software upgrade.
