SoC system-on-chip GR5405

The Goodix GR5405 comprehensive-performance automotive Bluetooth LE 5.3 SoC is developed in accordance with the AEC-Q100 Grade 2 standard, ideal for various automotive applications such as digital car key, tire pressure monitoring, automotive battery pack monitoring, and wireless connection in smart cockpits. Based on Arm® Cortex®-M4F CPU core running at 64 MHz, the GR5405 integrates a 2.4 GHz RF transceiver, Bluetooth LE 5.3 protocol stack, 512 KB on-chip Flash memory, 96 KB system SRAM, and a rich set of peripherals. It provides outstanding RF performance, featuring a maximum TX power of +15 dBm, an RX sensitivity of -99 dBm in Bluetooth LE 1 Mbps mode, achieving a total link budget of up to 114 dB. With two main power supply schemes (DC-DC and SYS_LDO), the GR5405 offers flexible options to achieve a balance between low power consumption and economical BOM.
