Diferencias entre TI CC2640R2L y CC2640R2F
The CC2640R2L recently launched by TI (Texas Instruments) is a 2.4 GHz wireless microcontroller (MCU) supporting Bluetooth® 5.1 features: LE Coded PHYs (Long Range), LE 2-Mbit PHY (High Speed), Advertising Extensions, Multiple Advertisement Sets, as well as backwards compatibility and support for key features from the Bluetooth® 5.0 and earlier Low Energy specifications. CC2640R2L and CC2640R2F both use a single-core software development kit (SDK) and a rich tool set to share a common and easy-to-use development environment. The low-power wireless microcontrollers CC2640R2F and CC2640R2L, both launched by Texas Instruments, can transmit and receive radio frequency signals with a larger range. CC2640R2L, as a low-cost version of CC2640R2F, is lower in price. Judging from the Bluetooth protocol supported by the chip, CC2640R2F supports BLE 5.0 protocol, and CC2640R2L supports BLE 5.1 protocol. CC2640R2L can use AOA/AOD for indoor positioning, which is very suitable for improving the performance of Internet of Things (IoT) applications. In terms of cores, both CC2640R2L and CC2640R2F are the same: 48 MHz ARM® Cortex®-M3 cores, and they both have 275 KB non-volatile memory, including 128 KB in-system programmable flash, up to 28 KB system SRAM, of which 20 KB is ultra-low leakage SRAM. Compared with CC2640R2F, CC2640R2L does not have a Sensor Controller Engine, so the cost of CC2640R2L is lower and it is more suitable for the application scenarios of basic transparent transmission function.
