The LS2640MR2 module is based on the SimpleLink CC26xx wireless MCU, a member of the CC26xx family of cost-effective, ultra-low-power, 2.4-GHz RF devices. Very-low active RF and MCU current and low-power mode current consumption provide excellent battery lifetime and allow for operation on small coin-cell batteries and in energy-harvesting applications.
The LS2640MR2 module contains a 32-bit ARM Cortex-M3 processor that runs at 48 MHz as the main processor and a rich peripheral feature set that includes a unique ultra-low-power sensor controller. This sensor controller is good for interfacing with external sensors or for collecting analog and digital data autonomously while the rest of the system is in sleep mode. Thus, the LS2640MR2 device is good for applications within a wide range of products including industrial, consumer electronics, and medical devices.
The LS2640MR2 module is pre-certified for operation under the regulations of the FCC, IC, ETSI, and ARIB. These certifications save significant cost and effort for customers when integrating the module into their products.
The Bluetooth low energy controller and the IEEE 802.15.4 MAC are embedded in the ROM and are partly running on a separate ARM® Cortex®-M0 processor. This architecture improves overall system performance and power consumption and makes more flash memory available.
