I purchased two LAUNCHXL-CC1352P1 development boards from TI. CC1352P is a multi-band wireless MCU. LAUNCHXL-CC1352P1 supports a maximum transmission power of 20dBm at SUB-1G and a maximum transmission power of 5dBm at 2.4G.
“The CC1352P device is part of the SimpleLink microcontroller (MCU) platform, which includes Wi-Fi, Bluetooth low energy, Sub-1 GHz and host MCU…” When selecting the board, I mistakenly thought that CC1352P supported WI-FI, BLE and SUB-1G. Later, after looking at the information carefully, I found that CC1352P did not support WI-FI function. , sans-serif]

In the schematic diagram, we can see that CC1352P1 has three groups of RF outputs, namely 2.4G, SUB-1G and PA output
The three sets of outputs are connected to the gallium arsenide SP3T RF switch through the balun circuit and then to the PCB antenna

The CC1350P part is the same as other Launchpads except for the three sets of RF outputs. It is basically a minimal system without other complex circuits.
After a few days of waiting, I received the package from FedEx. The speed was very fast.
sans-serif]After unpacking, I found that the color of the board I received was slightly different from the official picture. Mine is dark red, and the silk screen is missing under the antenna. The rest is basically the same.
CC1352 supports BLE 5.0 protocol, after flashing the firmware under C:\ti\simplelink_cc13x2_sdk_2_20_00_71\examples\rtos\CC1352P1_LAUNCHXL\ble5stack\simple_peripheral, you can install the Simplelink Starter software test on your phone
sans-serif]A careful observation will reveal that the simulation circuit part of LAUNCHXL-CC1352P1 is different from that of other previous Launchpads.
The same XDS110 emulator LAUNCHXL-CC2640R2 is like this
LAUNCHXL-CC1352P1 is like this
Open the schematic diagram and you can see that LAUNCHXL-CC1352P1 has a USB3300-EZK in front of the TM4C1294NCPDTT3R. This is Microchip's USB2.0 HS PHY. Using USB high-speed PHY should make the communication rate of debugging and USB to serial port many times faster. In addition to the USB high-speed PHY, many other chips can be seen in the simulation circuit part, such as large inductors, large chip resistors, large crystal oscillators, etc. These devices belong to the EnergyTrace part, which is used to monitor the operating current of CC1352P, etc. Normal current detection can be accomplished through the 12-bit 2MSPS ADC in the TM4C1294NCPDTT3R chip, but the LAUNCHXL-CC1352P1 actually uses an ADS127L01IPBS, a 24-bit 512KSPS ADC, which is high-end and classy.
In order to cooperate with ADS127L01IPBS, the board is also equipped with REF5025AID voltage reference, INA118U instrument amplifier, TPS65130RGE positive and negative output boost converter, TPS7A49 and TPS7A3001 ultra-low noise and high PSRR LDO, etc.
With such a powerful analog circuit lineup, the EnergyTrace function has become the one I want to test most after getting this development board.

After running the program, the current detection is like the picture above. It doesn’t have too many functions and it doesn’t run smoothly. It’s quite disappointing.
The current detection function of the EFM32 development board has always been the best I have used. This time I thought it would be surpassed by TI, but when I saw this software interface, I felt relieved.
Looking at the 1% accuracy and 200ppm/C temperature coefficient of the resistor R76 used to detect current, there is definitely no hope.
