CP2104-F03-GM SINGLE-CHIP USB-TO-UART BRIDGE

CP2104-F03-GM I/O Controller Interface IC USB to UART bridge 3.3 V

The CP2104 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232/RS-485 designs to USB using a minimum of components and PCB space. The CP2104 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, one-time programmable ROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 4 x 4 mm QFN-24 package (sometimes called “MLF” or “MLP”). No other external USB components are required.

The on-chip one-time programmable ROM may be used to customize the USB Vendor ID, Product ID, Product Description String, Power Descriptor, Device Release Number, Device Serial Number, and GPIO configuration as desired for OEM applications.

Nexys 4 DDR Artix-7 FPGA: Trainer Board Recommended for ECE Curriculum

The Nexys 4 DDR is a drop-in replacement for our cellular RAM-based Nexys boards. Featuring the same Artix™-7 field programmable gate array (FPGA) from Xilinx®, the Nexys 4 DDR is a ready-to-use digital circuit development platform designed to bring additional industry applications into the classroom environment. The Artix-7 FPGA is optimized for high performance logic, and offers more capacity, higher performance, and more resources than earlier designs. With its large, high-capacity FPGA (Xilinx part number XC7A100T-1CSG324C) and collection of USB, Ethernet, and other ports, the Nexys 4 DDR can host designs ranging from introductory combinational circuits to powerful embedded processors. Several built-in peripherals, including an accelerometer, a temperature sensor, MEMs digital microphone, speaker amplifier and plenty of I/O devices allow the Nexys 4 DDR to be used for a wide range of designs without needing any other components. The most notable improvement is the replacement of the 16 MiB CellularRAM with a 128 MiB DDR2 SDRAM memory. Digilent will provide a VHDL reference module that wraps the complexity of a DDR2 controller and is backwards compatible with the asynchronous SRAM interface of the CellularRAM, with certain limitations.

The Nexys 4 DDR is compatible with Xilinx's new high-performance Vivado® Design Suite as well as the ISE® toolset, which includes ChipScope™ and EDK. Xilinx offers free WebPACK™ versions of these toolsets, so designs can be implemented at no additional cost.
