This is the high-density Flash variant of the CC2541 family, which matters when the application code plus BLE stack and OTA update staging area must fit without external memory. The 23 GPIOs give enough headroom for a sensor hub or beacon with a handful of peripherals — I²C, SPI, and USART interfaces are on board for external sensors or displays. ## -99 dBm sensitivity at 2 Mbps — what the link budget buys The receiver sensitivity of -99 dBm at the maximum 2 Mbps data rate is the figure that sets the usable range in a BLE link. At 0 dBm transmit power, the path loss budget runs about 99 dB before the link drops. The modulation options — GFSK and MSK — let you trade off data rate against interference robustness; GFSK is the standard BLE choice for most applications. Current draw sits at 17.9 mA to 20.2 mA receiving and 16.8 mA to 18.2 mA transmitting.","metaTitle":"CC2541F256RHAR Texas Instruments Bluetooth v5.0 SoC","metaDescription":"Texas Instruments CC2541F256RHAR TxRx + MCU with Bluetooth v5.0, 2.4GHz, 256kB Flash, 8kB RAM, -99dBm sensitivity, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF & Wireless ICs"],"specifications":{"Mfr":"Texas Instruments","GPIO":"23","Type":"TxRx + MCU","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"Bluetooth v5.0","Frequency":"2.4GHz","Modulation":"GFSK, MSK","Memory Size":"256kB Flash, 8kB RAM","Sensitivity":"-99dBm","Mounting Type":"Surface Mount","Package / Case":"40-VFQFN Exposed Pad","Power - Output":"0dBm","Product Status":"Active","Data Rate (Max)":"2Mbps","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 3.6V","Serial Interfaces":"I²C, SPI, USART","RF Family/Standard":"Bluetooth","Base Product Number":"CC2541","Current - Receiving":"17.9mA ~ 20.2mA","Operating Temperature":"-40°C~85°C","Current - Transmitting":"16.8mA ~ 18.2mA","Supplier Device Package":"40-VQFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/faaf89b8c0e909ac357d583174f7f446.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CC2541F256RHAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CC2541F256RHAR when reusing this data.
