The 10 GPIOs and serial interfaces (I²C, I²S, JTAG, SPI, UART) give you enough flexibility for sensor nodes, beacons, or HID devices without needing a separate host MCU. ## Active lifecycle — no end-of-life surprise The base product number is CC2640, and the full order code CC2640F128RSMR resolves to the 32-VQFN (4x4) package variant. ## Supply voltage and current — what to budget The supply range spans 1.8 V to 3.8 V, which covers a single Li-ion cell or two alkaline cells. In receive mode the chip draws 5.9 mA to 6.1 mA; transmitting at 5 dBm output power pulls 6.1 mA to 9.1 mA. Those numbers are typical for a BLE SoC of this vintage — budget the transmit current for your battery-life calculation. ## Package and footprint — 32-VQFN with exposed pad Housed in a 32-VFQFN with an exposed thermal pad, the package measures 4x4 mm (supplier device package 32-VQFN). The pad needs a good via stitch to the ground plane to keep the junction temperature under control during continuous transmit.","metaTitle":"TI CC2640F128RSMR Bluetooth 4.1 SoC, 128KB Flash","metaDescription":"Texas Instruments CC2640F128RSMR SimpleLink™ Bluetooth v4.1 SoC with 128KB Flash, 28KB SRAM, -97dBm sensitivity, 10 GPIOs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF & Wireless ICs"],"specifications":{"Mfr":"Texas Instruments","GPIO":"10","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 (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b77469692e9bd93a1e8ede69a5c2d0c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CC2640F128RSMR compatible with Bluetooth 5?","answer":"No, this device implements Bluetooth v4.1.
