The -97 dBm receiver sensitivity gives you a solid link budget for BLE applications where the antenna is embedded or the device sits behind a metal enclosure — think asset tags, environmental sensors, or portable medical peripherals. The 5 dBm transmit output lets you push through a few extra metres of range without an external PA, though the 6.1 mA to 9.1 mA transmit current means the battery budget needs checking against the duty cycle. ## 128 kB Flash, 28 kB SRAM — sizing the firmware footprint 128 kB of on-chip Flash is enough for a full BLE stack plus a modest application layer — think sensor polling, simple data logging, or a GATT server with a few characteristics. The 28 kB SRAM handles the connection buffers and runtime heap; if your design needs over-the-air firmware updates, the OTA image size and the RAM for the update process will eat into that headroom, so budget accordingly. The 15 GPIOs cover a handful of sensors, LEDs, and a button without needing an external I/O expander. The 32-VQFN (5x5) package with exposed pad needs a good thermal via stitch under the pad if you plan to run continuous transmissions near the upper temperature limit — the pad is the primary heat path.","metaTitle":"CC2640F128RHBT Texas Instruments SimpleLink Bluetooth 5.1","metaDescription":"Texas Instruments CC2640F128RHBT SimpleLink wireless MCU with Bluetooth v5.1, 128 kB Flash, 28 kB SRAM, -97 dBm sensitivity, 15 GPIOs, 32-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF & Wireless ICs"],"specifications":{"Mfr":"Texas Instruments","GPIO":"15","Type":"TxRx + MCU","Series":"SimpleLink™","Package":"Tape & Reel (TR) Cut Tape (CT)","Protocol":"Bluetooth v5.1","Frequency":"2.4GHz","Modulation":"DSSS, O-QPSK, GFSK","Memory Size":"128kB Flash, 28kB SRAM","Sensitivity":"-97dBm","Mounting Type":"Surface Mount","Package / Case":"32-VFQFN Exposed Pad","Power - Output":"5dBm","Product Status":"Active","Data Rate (Max)":"1Mbps","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 3.8V","Serial Interfaces":"I2C, I2S, JTAG, SPI, UART","RF Family/Standard":"Bluetooth","Base Product Number":"CC2640","Current - Receiving":"5.9mA ~ 6.1mA","Operating Temperature":"-40°C ~ 85°C","Current - Transmitting":"6.1mA ~ 9.1mA","Supplier Device Package":"32-VQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.7500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b77469692e9bd93a1e8ede69a5c2d0c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CC2640F128RHBT?","answer":"The CC2640F128RHBT is part of the SimpleLink CC2640 family.
