Laser controller

The application of laser controllers requires precise control of laser intensity. Therefore, during PWM output, a feedback circuit is needed to detect accuracy, requiring extremely short reaction time. This CPLD precisely plays a role.
It is difficult to improve the real-time performance of the system using a single MCU scheme. Due to the parallelism of functions such as laser driving, echo signal processing and analysis, using CPLD to achieve relevant control and feedback processing analysis is beneficial for enhancing the real-time performance of the system, improving the measurement accuracy, and having greater flexibility is beneficial for later maintenance and upgrading.

The AG32 series MCU products have built-in CPLD logic inside the chip, which can effectively meet the needs of laser controllers 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.
