It carries 128 KB of Flash and 28 KB of SRAM, enough to run a BLE 5.0 stack plus a modest application layer without external memory. The radio delivers a 5 dBm output power and a -103 dBm receiver sensitivity, giving a real link-budget advantage over 0 dBm parts for range-critical designs like asset trackers or building-automation sensors. ## Supply range, current draw, and temperature grade Receiving current is 5.9 mA; transmitting at 5 dBm draws 9.1 mA. ## Peripheral set and GPIO count Ten GPIOs are brought out, along with serial interfaces I²C, I²S, SPI, and UART. That is enough for a sensor hub with an external flash or a MEMS sensor plus a host UART, but tight if you need parallel LCD or many discrete I/Os. The GFSK modulation is standard BLE; no proprietary modes are exposed here. ## Lifecycle and sourcing This is a current-production part from TI's SimpleLink family, widely available through distribution. The CC2640R2F base number shares the same package and pinout across the RSM package variants, so a shift to a sibling density option is straightforward if firmware size changes.","metaTitle":"CC2640R2FRSMR Bluetooth 5.0 MCU, 128 KB Flash, 5 dBm","metaDescription":"Texas Instruments CC2640R2FRSMR SimpleLink wireless MCU with Bluetooth 5.0, 128 KB Flash, 28 KB SRAM, -103 dBm sensitivity, 5 dBm TX.","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 v5.0","Frequency":"2.4GHz","Modulation":"GFSK","Memory Size":"128kB Flash, 28kB SRAM","Sensitivity":"-103dBm","Mounting Type":"Surface Mount","Package / Case":"32-VFQFN Exposed Pad","Power - Output":"5dBm","Product Status":"Active","Data Rate (Max)":"2Mbps","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 3.8V","Serial Interfaces":"I²C, I²S, SPI, UART","RF Family/Standard":"Bluetooth","Base Product Number":"CC2640","Current - Receiving":"5.9mA","Operating Temperature":"-40°C~85°C","Current - Transmitting":"9.1mA","Supplier Device Package":"32-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5cc94614aa328f20d034165719ceebf7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CC2640R2FRSMR support Bluetooth 5.2?","answer":"No, the CC2640R2FRSMR supports Bluetooth v5.0.
