CC1310 Description
The CC1310 device is a cost-effective, ultra-low-power, Sub-1 GHz RF device from Texas Instruments™ that is part of the SimpleLink™ microcontroller (MCU) platform. These devices all share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich tool set. A one-time integration of the SimpleLink platform enables users to add any combination of devices from the portfolio into their design, allowing 100 percent code reuse when design requirements change. For more information, visit www.ti.com/simplelink.
With very low active RF and MCU current consumption, in addition to flexible low-power modes, the CC1310 device provides excellent battery life and allows long-range operation on small coin-cell batteries and in energy harvesting applications.
The CC1310 device combines a flexible, very low-power RF transceiver with a powerful 48-MHz Arm® Cortex®-M3 microcontroller in a platform supporting multiple physical layers and RF standards. A dedicated Radio Controller (Cortex®-M0) handles low-level RF protocol commands that are stored in ROM or RAM, thus ensuring ultra-low power and flexibility. The low-power consumption of the CC1310 device does not come at the expense of RF performance; the CC1310 device has excellent sensitivity and robustness (selectivity and blocking) performance.
The CC1310 device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC/DC converter.
Sensors can be handled in a very low-power manner by a dedicated autonomous ultra-low-power MCU that can be configured to handle analog and digital sensors; thus the main MCU (Arm® Cortex®-M3) can maximize sleep time.
The power and clock management and radio systems of the CC1310 device require specific configuration and handling by software to operate correctly, which has been implemented in the TI-RTOS. TI recommends using this software framework for all application development on the device. The complete TI-RTOS and device drivers are offered free of charge in source code.
CC1190 Description
CC1190 is a cost-effective and high-performance RF Front End for low-power and low-voltage wireless applications at 850 - 950 MHz.
CC1190 is a range extender for the sub-1 GHz low-power RF transceivers, transmitters, and System-on-Chip devices from Texas Instruments.
CC1190 integrates a power amplifier (PA), a low-noise amplifier (LNA), switches, and RF matching for the design of a high-performance wireless systems.
CC1190 increases the link budget by providing a power amplifier for increased output power, and an LNA with low noise figure for improved receiver sensitivity.
How to test N620PA module
Take the supporting base plate of Heyan technology as an example:
The bottom board of N620PA is T532AP, which integrates USB to serial chip, led, button, burning port and module card port. As shown in the figure:
N620PA secondary development method
The CC1310 module is stuck on the backplane as shown in the figure, and the IPEX is connected with the antenna. The burning port is connected with xds110 according to the silk screen printing, and then online simulation can be carried out to test the performance of the module.
