For a sensor node running the BLE stack and a small application loop, this memory budget is typical. If the design requires over-the-air firmware updates or a larger application image, the 128 kB Flash may be tight — plan the memory map early. ## Bluetooth v4.1 — not Bluetooth 5 compatible This part implements Bluetooth v4.1, which means it does not support Bluetooth 5 features such as 2 Mbps PHY, extended advertising, or LE Audio. For BLE 4.1 applications (beacons, remote sensors, HID devices), this part is well matched. ## -97 dBm sensitivity and 5 dBm TX power — link budget for range Receiver sensitivity of -97 dBm and a maximum transmit power of 5 dBm give a link budget around 102 dB in free space, which translates to roughly 100–200 meters line-of-sight depending on antenna and environment. For indoor applications through walls, expect 20–40 meters. The 1 Mbps data rate is the standard BLE 4.1 rate. ## 15 GPIOs and serial interfaces Fifteen GPIOs are available on the 32-VQFN package. The serial interface set includes I2C, I2S, JTAG, SPI, and UART, which covers most sensor and actuator peripherals. The JTAG interface is the primary debug and programming port; TI's CC13xx/CC26xx SDK and a compatible debug probe (e.g., XDS110 or LAUNCHXL-CC2640R2) are used for development.","metaTitle":"CC2640F128RHBR SimpleLink Bluetooth 4.1 MCU, 128 kB Flash","metaDescription":"TI CC2640F128RHBR TxRx + MCU with 128 kB Flash, 28 kB SRAM, -97 dBm sensitivity, Bluetooth v4.1.","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 v4.1","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":"$6.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b77469692e9bd93a1e8ede69a5c2d0c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can CC2640F128RHBR be used as a drop-in replacement for CC2640R2F?","answer":"No. The CC2640F128RHBR supports Bluetooth v4.1, while the CC2640R2F supports Bluetooth 5. The two parts are not pin-compatible for a drop-in replacement; the firmware stack and memory layout differ.

For BLE 4.1, typical implementations support up to eight connections in the peripheral role, but this depends on the stack configuration and available SRAM (28 kB).
