AG32+SDRAM/FSRAM custom packaging

The internal storage of AG32 includes 128KB of SRAM. In some applications, for high memory requirements such as running GUI or algorithms, the built-in memory may not be sufficient, so it is necessary to expand SRAM or SDRAM externally.

AG32 can encapsulate SDRAM/PSRAM into chips according to customer needs, providing fast and reliable support for data processing and storage. The capacity options range from 2MB-8MB and can support up to 64MB.On the current AG32, we can first use CPLD to extend an SDRAM interface to verify this part of the functionality. If there is a need in the future, we can customize the sealing according to customer requirements.

In addition, AG32 combines the advantages of MCU and FPGA, with high integration, good stability, flexible design, and high efficiency. After stacking SDRAM/PSRAM, the board area is reduced and product costs are reduced. At the same time, it greatly improves the convenience of EMC related design in PCB layout, and can meet various related needs, such as screen control, printing/inkjet control, etc.

For example, the following screen control application cases.

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 FPGA of AG32 communicate at high speed through the internal AHB bus of the chip, far exceeding the speed of traditional SPI.
5. AG32 built-in FPGA can achieve customized logic functions for customers, including interface IP, Decoder, and other functions.
