HPM Daughter Board Series

Overview

HPM series MCU is a high-performance real-time RISC-V microcontroller from Shanghai HPM Semiconductor Technology Co., Ltd., which provides great computing power and efficient control capability for industrial automation and edge computing applications. Shanghai HPM Semiconductor has currently released multiple series of high-performance microcontroller products, such as , HPM5300, HPM6700/6400, HPM6300, HPM6200,, HPM6E00 etc.

In order to help users develop the performance of Xianji MCU more comprehensively, HPM has launched a series of daughter boards that are used in conjunction with HPMEVK development boards. Some daughter boards are not sold and only provide hardware design materials including hardware design drawings, user guides, and software testing routines.

HPM6E00EVKSRAMSDRAM Daughter Board

This example project demonstrates how to use the HPM6E00EVK_SRAM daughter board with the HPM6E00EVK to read and write to an external asynchronous SRAM memory device using the PPI peripheral.

Hardware Support

Please read hardware schematic HPM6E00EVKSRAMSDRAMRevA
Please See the hardware engineering path：(hpm_apps\apps\daugherboard\hardware\HPM6E00\HPM6E00EVKSRAMDRAMRev-Project Files)

Device Connection

• Connect PC USB to DEBUG Type-C interface
• Connect the debugger to the JTAG interface
• Insert this daughter board source into the corresponding interface of the HPM6E00EVK.
