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
- Pin and lead:
– 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:
– Micro USB 5V power supply; 2.54mm pin
– 3.3V~5V power supply; 1.27mm stamp hole power supply
– 3-channel DCDC power supply chip, stable and efficient power supply
– independent adjustment of Bank0 IO level
