The OM6621Fx 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. OM6621Fx 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.
OM6621Fx on-chip Bluetooth system compliant with version 5.1, supports all Bluetooth standard 4.2 feature.
The chip integrates up to 64MHz high-performance MCU, DMA, GPIO, SPI, UART, Timer, Watchdog, supports 32MHz external crystal, integrates multi-purpose 10bit ADC.
The OM6621Fx integrates on chip 16K SRAM, 24K OTP and supports user defined IDE system on chip SFLASH MCU development and JTAG software upgrade.
