ICE40 FPGA:

The ICE40 chip is an ultra-low-power FPGA and sensor manager designed for ultra-low power mobile applications, such as smartphones, tablets, and hand-held devices. It provides controls for driving the 24 mA LED Sink driver, including color controls, LED ON/OFF time, and breathing rate. It also provides flexible, reliable, and secure configuration from on-chip NVCM (Non-Volatile Configuration Memory). It has two On-Chip Oscillators one is a low-frequency oscillator of 10 kHz and the other is a high-frequency oscillator of 48 MHz. It is useful in different applications;

• Voice Recognition Application
• In Smartphones, Tablets, and Consumer Handheld Devices
• For Multi-Sensor Management Applications

Major Circuitry Parts:

This FPGA PCB module consists of the following major components to drive an LED matrix:

• IC 93LC56B
• IC 74HC5 Level Shifter
• IC FT232HL
• SPI Flash IC

Schematic:

For the design implementation, I have decided to work on Altium which is very useful and efficient for complex designs. After creating my schematic I have uploaded my schematic file online on Inventhub for the users. Anyone who wants to implement my design can visually view or download the file from Inventhub and can implement my design.

PCB:

Once I have done designing my board I have uploaded the PCB design file online on Inventhub. The manufacturer can view or download my PCB design file to fabricate my board without any error. I have implemented the PCB design of this FPGA board on Altium. After completing the routing I can view the board in 2D or 3D to get an idea of how it will look after fabrication.

LED Matrix Driving Framework:

The framework to drive LED matrix works in three steps:

1. Fetches the data in the form of frame buffer memory
2. Transmit this data through the data transmitter to read it and clock it
3. Wait for the correct timing before the next row of data can be sent

Bill of Material:

For hardware components, I have created a BOM file online on Inventhub where I have mentioned each and every detail of my components like names, footprint, library, and quantity. To embed components on my PCB board I can send this file in CSV format to the component provider. He can download the file and can deliver my components as per my design requirements.
