OM6621P

The OM6621Px 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.OM6621Px also integrates a power management to provide high-efficient power management. It targets 2.4GHz Bluetooth low energy systems, proprietary 2.4GHz systems, Human-Interface Devices (smart watch, bracelets, smart lock, smart switch,etc.), sports and leisure equipment, mobile phone accessories and consumer electronics.

OM6621Px on-chip Bluetooth system support BLE5.1 full feature.

The chip integrates up to 128MHz high-performance MCU, GPIO, DMA, UART, I2S, I2C, SPI, Timer, RTC, Watchdog, PIC_DEC, supports 32MHz external crystal, integrates multi-purpose 12-bit ADC.

The OM6621Px supports user defined IDE system on chip SFLASH MCU development and JTAG software upgrade.
