$18 Tang Nano 4K FPGA board comes with HDMI output, optional camera

Tang Nano 4K FPGA board

Sipeed’s Tang Nano 4K FPGA board is an upgrade to the company’s Tang Nano FPGA board with a more powerful GOWIN GW1NSR-LV4C FPGA with 4608 LUT (instead of 1152) and a Cortex-M3 microcontroller embedded into the chip. Like the previous board, the new Tang Nano 4K features a USB-C port for power and downloading the bitstream, but replace the RGB LCD interface with an HDMI port, and adds support for an optional OV2640 camera. Tang Nano 4K board specifications: FPGA – GOWIN GW1NSR-LV4C aka GW1NSR-4C (See PDF datasheet for details) with 4608 logical units (LUTs) 3456 registers 16 multiplier parameters 180Kbit block SRAM, 64Mbit PSRAM 2x PLL Up to 44x user I/O Arm Cortex-M3 hard processor Storage – 32 Mbit NOR flash Video Output – HDMI port Camera I/F – DVP camera connector for OV2640 camera sensor up to 1600 x 1200 (UXGA) resolution USB – USB Type-C port for […]

GOWIN GW1NRF FPGA Comes with Bluetooth 5.0 LE Radio & 32-bit ARC MCU

GW1NRF Bluetooth FPGA

I first heard about GOWIN Semiconductor last month when I found out about Sipeed Tang Nano FPGA board going for $5 and featuring GOWIN GW1N FPGA. The company has now announced what it claims is the first Bluetooth FPGA on the market with GW1NRF FPGA integrating a Bluetooth 5.0 LE radio and a 32-bit ARC microcontroller beside FPGA fabric. GOWIN GW1NRF-LV4N uSoC FPGA key features and specifications: FPGA Fabric – 4.6K LUTs, 180 Kb block SRAM, and 16 multipliers MCU – 32-bit ARC microcontroller with 48KB IRAM, 48KB DRAM 136KB block ROM, 128KB block OTG Security – AES-128, RNG, Key GEN Power Management – Wake-up timer, pin monitoring Wireless – Bluetooth LE (Low Energy) 5.0 Transceiver with PHY & MAC Power Supply  – 3V or 1.5 V with battery support via on-chip LDO regulator and step-up/step-down DCDC regular Power Consumption – 5nA power disable mode Package – 6x6mm QFN48 package […]

$5 Tang Nano FPGA Board Features GOWIN GW1N “LittleBee” FPGA

Last year, we wrote about Lichee Tang FPGA board powered by Anlogic EG4S20 FPGA and targeting RISC-V development for just under $15. The company, now called Sipeed, has made an even cheaper FPGA board with Tang Nano equipped with GOWIN Semi GW1N FPGA part of the company’s LittleBee family. Sipeed Tang Nano Sipeed Tang Nano specifications: FPGA – Gowin GW1N-1-LV FPGA with 1,152 LUT4, 864 Flip-Flops(FF), 72Kbit Block SRAM, 4x B-SRAM, 96Kbit user flash, 1x PLL, 4x I/O banks System Memory – 64Mbit (8MB) 3.3V PSRAM Display – Standard 40-pin RGB LCD interface with on-board screen backlight driver circuit (default normally open, EN pin can be connected to FPGA) USB – USB Type-C port for download and power supply Expansion – 34 I/O ports and power pins on headers (unpopulated), breadboard-compatible Misc – RGB LED, 2x user buttons, 24MHz crystal oscillator Power Supply – 5V via USB-C port (at least […]
