Overview
The GW1NRF series of FPGA products are the first generation
products in the LittleBee
®
family and represent one form of SoC FPGA.
The GW1NRF series of FPGA products integrate 32 bits hardcore
processor and support Bluetooth 5.0 Low Energy radio. They have
abundant logic units, IOs, built-in B-SRAM and DSP resources, power
management module, and security module. The GW1NRF series provides
low power consumption, instant on, low cost, non-volatile, high security,
various packages, and flexible usage.
