GR5405

The Goodix GR5405 automotive-grade Bluetooth LE 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 excellent RF performance, with a maximum of +15 dBm TX power, –99 dBm RX sensitivity, and a maximum of 114 dB link budget in Bluetooth LE 1 Mbps mode.

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.
