AG32 Automotive UWB Application Scheme

The increasing maturity of automotive electronic products, including ADAS and in car entertainment, is driving demand for CPLD. For example, using various sensors installed on the vehicle (such as radar, cameras, and LiDAR) to perceive the surrounding environment, achieving real-time monitoring and data processing. These sensors require high-performance CPLD for high-speed data processing and logic control to ensure the accuracy and reliability of ADAS.

With the intensification of market competition, the speed of electronic product updates is getting faster, and design specifications are also frequently changing. CPLD has high flexibility and customizability, which can quickly adapt to changes in design specifications, meet different product needs and personalized and differentiated consumer needs. It also helps to improve product performance and reliability, shorten research and development cycles, and reduce production costs.
The combination of UWB and BLE (Bluetooth) wireless technology enables keyless entry and engine start through compatible mobile devices. The specific application of UWB in the automotive industry lies in its precise positioning and precise determination of the distance inside and around the vehicle. For example, it is a new application for detecting people and animals inside the vehicle, automatic valet parking, automatic payment, and so on. In addition, for intelligent summoning functions similar to those provided by Tesla, if the GPS signal is poor (such as in an underground parking lot), the vehicle can also be automatically called to the precise location of the owner through the positioning signal provided by UWB. The automatic opening function of the car trunk is also an application of UWB.

The AG32 series MCU products have built-in CPLD logic and comparators within the chip, and can be customized and developed with unique functions through CPLD logic. Combined with high-performance UWB chips for data transmission and parameter configuration, they can effectively meet various data collection needs in vehicles and reduce customer BOM costs.

Plan features:
1. AG32 has a maximum clock frequency of 248MHz and a wide range of peripherals, including five UARTs, two I2Cs, and supports USB, CAN, and SPI channels. With its high-speed instruction execution speed, convenient JTAG debugging method, and low power consumption, it provides a relatively complete platform for data acquisition and processing design.
2. AG32 has a 3x12 bit maximum of 3M SPS ADC (17 channels), 2 DACs, and provides two dual channel comparators.
3. AG32 is initially compatible with STM32 pins, but can be flexibly redefined through configuration files for use by MCU and CPLD in the kernel, thus providing more GPIO ports than STM32.
4. The MCU and CPLD of AG32 communicate at high speed through the internal AHB bus of the chip, far exceeding the speed of traditional SPI.
5. AG32 has a built-in CPLD that enables customized logic functions for customers.
6. Provides over 32/48/64/100 packages.
