Now, let me give you an early experience of this high-performance dual-core Bluetooth SoC and its evaluation board. This chip features the CM33 ARM core, with a maximum clock speed of 156MHz, and a Bluetooth co-processor with a clock speed of 48MHz. This combination is quite impressive. Next, let’s explore what wonderful experiences this configuration can bring to users.

FR3068E-C Chip Resources and Performance

The FR306x-C series chips are low-power, high-security high-performance wireless MCUs, equipped with Bluetooth BR/EDR/BLE transceivers and controllers, as well as a CAN FD bus controller, making them very suitable for applications in various fields such as industrial and automotive electronics.

The FR306x-C complies with Bluetooth V5.3 standards, supporting BR 1Mbps GFSK, EDR 2Mbps π/4-DQPSK, 3Mbps 8DPSK; BLE 1M/2Mbps GFSK, 125K/500K multiple modes, supporting separate enabling and disabling of different modes, and supporting Bluetooth multi-master and multi-slave connections.

The FR306x-C supports the AUTOSAR software framework; it has up to 2 independent CAN FD controllers that are downward compatible with CAN 2.0 A/B. In addition, I have compiled a table and block diagram of detailed features and resources for everyone to refer to:

FR3068E-C Evaluation Board Resource Introduction

Let me first show a few static photos. The evaluation board comes with an LCD screen and peripherals including RGB888/565 interface, RS232, CAN-FD interface, RS485, Audio-PA, MIC, TF Card, KEY, RESET, rotary encoder, FLASH, LCD interface, TYPE-C for power and download, USB Host, and Debug interface. You can see that this small board covers most industrial applications and some automotive applications.

Attached is the assembly diagram provided by the official for the evaluation board. The development board itself is a 4-layer board, taking into account the 2.4G RF part, along with the hardware function block diagram organized by me to share with everyone. Comparing the functional block diagram can help better understand the hardware design of the schematic. 😃

FR3068E-C Evaluation Board Performance Demonstration

The evaluation board comes with related demo examples when it leaves the factory. Here I have made a few GIFs to show you the performance-intensive display effects, which are quite good, including boot animations, dashboard displays, media players, menu combinations, etc.

FR3068E-C Evaluation Board User Experience

To edit the code, you first need to connect the debug port and the Type-C port to the PC. Furui Kun provides a complete SDK, which includes rich examples. Here we take the factory example for demonstration. It should be noted that the examples are opened with MDK, and the official provides a dedicated download tool that can directly download the Bin file to the chip without installation.
