Tang features Anlogic EG4S20 FPGA – unrelated to Amlogic – which run a RISC-V softcore, and all is packaged in a small small form factor
Specifications:
-
Core unit: Anlogic Technologies EG4S20
-
Logical unit: 20K (LUT4/LUT5 hybrid architecture)
-
SRAM: About 130KB
-
SDRAM: Built-in 32bit bit width 64MBit
-
Flash: FPGA configuration Flash, 8Mbit User Flash, nor/nand optional
-
Download and debug: Onboard FPGA JTAG Download Debugger, RV debugger can debug hummingbird core
-
Interface:
- FPC40P socket, can be connected to RGB LCD, VGA adapter board
- FPC24P socket, can be connected to DVP camera, high speed ADC module
- Resistive touch screen controller for I2C interface, used with RGB LCD
- The adjacent pins LVDS are drawn in the same length, leading out 8 GCLKs, and all 8 ADCs are taken out.
- Double row pin spacing 900mil, compatible with breadboard development
- Half hole leads to an extra 40 IO, and the whole board leads to 130+ IO
-
Electrical characteristics:

Precautions
|
|
RV debugging
|
When using the RV debugger, if you need to use USB power, try to use a shorter USB cable.
