Preface
The architecture of AGM AG32 is FPGA + MCU, and AG32 is key compatible with STM32. This low-cost AG32 device has obvious advantages in audio processing (speech recognition, noise reduction, sound enhancement, etc.) applications.
AG32 has built-in 2K FPGA resources and adopts RISC-V core. Through the combination of FPGA and RISC-V MCU, it can collect, filter, process algorithms and output sound signals more effectively and conveniently.
Pin Description of AGRV2K
1. AG32 has a maximum clock frequency of 248MHz and a rich set 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 the design of data acquisition and processing.
2. AG32 has a 3x12-bit ADC (17 channels) with a maximum of 3M SPS, and 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 the MCU and CPLD in the kernel, so it can provide more GPIO ports than STM32.
4. The MCU and CPLD of AG32 communicate at high speed through the AHB bus inside the chip, which is much faster than traditional SPI.
5. The built-in CPLD of AG32 can realize customized logic functions.
6. It provides 32/48/64/100 packages. Haizhenyuan Technology can provide technical support for users, and also provide business support for samples and bulk purchases.
