It carries AEC-Q100 automotive qualification, making it suited for in-vehicle wireless nodes such as tire-pressure monitors, keyless entry, and telematics modules where the operating temperature spans -40°C to 105°C. The part integrates 256kB Flash and 8kB RAM — enough to hold the Bluetooth stack plus a modest application layer, though firmware engineers should budget the stack footprint early. The 23 GPIO lines support I²C, SPI, and USART serial interfaces for external sensors or displays. ## Receiver sensitivity and output power The receiver sensitivity is rated at -94dBm — typical for Bluetooth 4.0 single-chip parts — which gives a usable link budget for short-range automotive links inside a metal chassis. The maximum output power is 0dBm, and the data rate reaches 2Mbps in Bluetooth 4.0 mode. Current consumption during receive is 18.3mA to 20.8mA, and during transmit 17.2mA to 18.6mA — both typical for this class of SoC. The supply voltage range is 2V to 3.6V, compatible with common 3.3V and 3.0V automotive rails. ## Package and footprint for the layout engineer The device is housed in a 40-VFQFN with exposed pad, size 6x6mm. The 0.5mm pitch QFN demands careful solder-paste stencil design to avoid bridging; a 4-layer PCB with a solid ground plane under the pad is recommended. Mounting is surface-mount. ## Production status and sourcing posture The part is sourced per RFQ — no stock-holding claim is made here.","metaTitle":"CC2541F256TRHATQ1 Texas Instruments Bluetooth 4.0 SoC","metaDescription":"Texas Instruments CC2541F256TRHATQ1 — Bluetooth v4.0 TxRx + MCU, 2.4GHz, 256kB Flash, 8kB RAM, -40°C to 105°C, AEC-Q100 automotive qualified.
