It integrates 128 kB of Flash and 28 kB of SRAM, enough to run the BLE 5.1 protocol stack alongside a moderate application — think environmental sensor nodes, beacons, or simple HID peripherals. The 31 GPIOs mean you can connect multiple sensors, buttons, and LEDs without an external I/O expander, saving board space and BOM cost. Receiver sensitivity is rated at -97 dBm, giving a solid link budget for indoor ranging and asset-tracking applications that need the coded PHY or direction-finding features in v5.1. The supply voltage spans 1.8 V to 3.8 V, so it can run directly from a single Li-ion cell or two alkaline batteries without an external regulator, though the RF output power (5 dBm typical) will drop at the low end of the range. Current consumption in receive mode sits between 5.9 mA and 6.1 mA; transmit draws 6.1 mA to 9.1 mA depending on output power setting, which matters for battery-life budgeting in coin-cell designs. ## Package and layout — 48-VQFN with exposed pad The CC2640F128RGZT comes in a 48-VFQFN package with an exposed thermal pad (supplier package designation 48-VQFN, 7x7 mm). The part is surface-mount only. ## Active lifecycle — no end-of-life concern for new designs The serial interfaces include I²C, I²S, JTAG, SPI, and UART, covering most sensor and peripheral connectivity needs.","metaTitle":"CC2640F128RGZT Bluetooth 5.1 MCU, 128kB Flash, -97dBm","metaDescription":"Texas Instruments SimpleLink CC2640F128RGZT: Bluetooth v5.1 TxRx + MCU, 128kB Flash, 28kB SRAM, -97dBm sensitivity, 5dBm output, 31 GPIOs, -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":"31","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":"48-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":"48-VQFN (7x7)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b77469692e9bd93a1e8ede69a5c2d0c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CC2640F128RGZT and CC2640R2F?","answer":"The CC2640R2F is a later-generation SimpleLink device with a different ARM core revision and updated BLE stack support.
