General Description

GPM4130A, a highly integrated SoC (System on a chip) by Generalplus, is a high cost-performance ratio solution for low-power IoT and high-end audio applications. It is developed with a high performance and power efficient ARM’s Cortex M4F core, capable of operating up to 193.5MHz with significant enhancements in FFT H/Wand power savings. Other features include TFT-LCD interface, CMOS sensor interface, 16-channel Sound Process Unit (SPU), USB 2.0 OHCI/EHCI, USB 2.0 HS device, etc. GPM4130A processor is designed to connect with various types of memory card interfaces such as SD and MMC. For more information about its features, please refer to the following section.
