Gowin’s LittleBee® product family provides a compact solution for those looking for flash-based, non-volatile FPGAs with an abundance of logic resources, multiple I/O standards, embedded RAM, DSPs, PLLs, embedded security, and additional user flash.
This development board (DK-UAC2_GW1N-LV9LQ144C7I6_V2.0) uses the largest-spec model of the traditional (non-expanded) LittleBee FPGAs, the GW1N-9, with 8,640 LUT4 and 6,480 flip-flops. This model includes additional shadow SRAM at 17,280 bits of capacity, 468 kb block SRAM, 608 kb flash, and a maximum of 276 I/Os. As with others in the range, the GW1N-9 has the same characteristics of low power consumption, instant-start, low cost, non-volatility, high security, convenient and flexible usage, etc., which can effectively reduce the learning cost and help users to quickly integrate such devices.
This application-specific board features two USB 2.0 interfaces and the following audio peripherals:
- 4x microphone chips, with support for I2C and I2S microphone inputs.
- CS8416-CZZR 8-channel audio receiver chip
- CS8406-CZZR digital audio interface chip
- CS4344-CZZR stereo audio DAC chip
- MAX98357AETE+T audio amplifier chip for 3.2 W output into 4Ω.
It also supports JTAG download and reserves GPIO interfaces, an LED, and keys to facilitate user testing.
