C3010130_CH395Q chip solution verification board

Overview

The CH395Q chip comes with 10/100M Ethernet media transmission layer (MAC) and physical layer (PHY), is fully compatible with IEEE802.3 10/100M protocol, and has built-in PPPOE, IP, DHCP, ARP, ICMP, IGMP, UDP, TCP, etc. Ethernet stack firmware. The microcontroller system can easily communicate via the CH395Q chip.

This solution verification board supports three communication interfaces: 8-bit parallel port, SPI interface or asynchronous serial port. The TXD pin is pulled up for an asynchronous serial port and pulled down for SPI. The chip has a built-in pull-up, which is reflected on the solution verification board as the welding of the R8 pull-down resistor. or not. The board has a 5V to 3.3V converter and supports 5V and 3.3V input.
