Automotive-grade BLE 5.1 SoC with -97 dBm link budget
It integrates a 2.4 GHz radio with a peak output of 5 dBm and a receiver sensitivity of -97 dBm, giving you a solid link margin for in-vehicle connectivity like keyless entry, tire-pressure monitoring, or diagnostic dongles. The on-chip MCU runs your BLE stack and application code from 128 kB Flash with 28 kB SRAM — enough headroom for a single-profile BLE app with OTA firmware updates.
105°C junction — under-hood placement without derating
The 48-VQFN (7x7) package with wettable flank supports automated optical inspection (AOI) on the assembly line — a requirement for many tier-1 automotive builds.
That means no last-time-buy clock ticking for production programs starting today.
31 GPIOs and serial interfaces for sensor fusion
With 31 GPIOs and serial interfaces including I²C, I²S, SPI, and UART, this SoC can talk to a MEMS accelerometer, a gyro, a pressure sensor, and a CAN transceiver all at once — typical for a BLE-connected automotive sensor hub. The 6.1 mA receive current is competitive for a battery-backed module that spends most of its life listening for a wake-up packet.
