In order to program your ICE40UP5K-SG48I FPGA, you'd typically use a JTAG or SPI interface. The ICE40UP5K-SG48I does natively support SPI configuration which utilises the following pins:

IOB_32A_SPI_SO: SPI Data out
IOB_34A_SPI_SCK: SPI Clock
IOB_35B_SPI_SS: SPI Chip Select
IOB_33B_SPI_SI_1 and IOB_33B_SPI_SI_2: SPI data in (You can choose to use IOB_33B_SPI_SI_1 or IOB_33B_SPI_SI_2 based on your design requirement)

For JTAG configuration, the ICE40UP5K-SG48I uses four standard JTAG signals which aren't individually broken out onto separate pins in the SG48 package.

Other critical pins for configuration are:

CDONE: This is an output pin which when HIGH indicates configuration is done.
CRESET_B: An active-low reset pin for configuration.

You could connect these to appropriate pins on your microcontroller or a standard SPI/JTAG interface tool.

If you are planning to use a particular configurator, please let me know so I could be more specific on pin connections or any additional requirements.

Sure, here are the connections you need to make to connect the FPGA for SPI programmability:

Connect IC1:IOB_32A_SPI_SO to your microcontroller SPI:MISO (Master In Slave Out). This is the signal from FPGA to MCU.
Connect IC1:IOB_34A_SPI_SCK to your MCU's SPI:SCK. This is the clock signal for the SPI interface and it synchronizes data transfer between the devices.
Connect IC1:IOB_35B_SPI_SS to your MCU's SPI:CS (Chip Select). This signal enables the FPGA when your MCU wishes to communicate with it.
Connect IC1:IOB_33B_SPI_SI_1 (or IC1:IOB_33B_SPI_SI_2) to your MCU's SPI:MOSI (Master Out Slave In). This is the data signal from the MCU to the FPGA.

To ensure correct operation after configuration, connect the CDONE pin to an input of your microcontroller, allowing the MCU to verify if configuration was successful. Also, connect the CRESET_B to a reset signal source in your system or to a reset button.

Bear in mind, the FPGA's power supply requirements also need to be fulfilled. Depending on your power setup, you may need to connect VCCPLL_1, VCCPLL_2, etc., to the appropriate voltage source. Do not forget the Ground pin connection, IC1:GND to the common ground of your circuit.

These connections will allow you to perform SPI configuration on the ICE40UP5K-SG48I FPGA. Please, ensure that your MCU has the necessary programming for performing the SPI configuration on the FPGA.

Remember, these are typical connections assuming a common setup, you'd need to adjust based on the specifics of your circuit.

@copilot Check that none of the unconnected pins require pull-up or pull-down resistors to ensure proper function.

The FPGA IC ICE40UP5K-SG48I that you have in your project generally has internal pull-up resistors that can be optionally enabled within the FPGA logic. However, the specific requirement of external pull-up or pull-down resistors can depend on the logic and inputs of your specific design.

Typically, certain pins such as the reset pin (CRESET_B) would need a pull-up resistor to ensure it remains inactive unless explicitly driven low. Similarly, the Done pin (CDONE) from your FPGA may also require a pull-up resistor to ensure the FPGA initializes properly upon power-up. The SPI bus (IOB_32A_SPI_SO, IOB_34A_SPI_SCK, IOB_35B_SPI_SS, and IOB_33B_SPI_SI_1) typically utilizes pull-up resistors in many designs to maintain a known state when the bus is not active.

Please note that this is common practice and you should refer to the specific datasheet of the IC (or the specific modules you are using inside the FPGA) to confirm if pull-up or pull-down resistors are required.

I would suggest that you review the datasheet for this chip again to confirm the behavior of each unconnected pin and check whether it needs to be pulled up or down for proper operation. Let me know if you need additional assistance.

ziondido

can you do it?

copilot

Apologies for any confusion. Based on standardized practices and the behavior of the ICs you're using, valuable insights and recommendations can be provided. However, it's essential to note that direct readings of datasheets or specific chip information aren't possible. It can't be automatically identified which pins on your IC require pull-up or pull-down resistors as this largely depends on your specific use case, design, and the designer's decision as well.

Accurate and detailed information is usually provided in the datasheet by the manufacturer. Therefore, for precise details, please refer to the datasheet of the ICE40UP5K-SG48I chip from Texas Instruments.

Generally speaking, your focus should be on the CRESET_B pin (this is typically active low, and you may want to add a pull-up resistor to keep the chip out of reset state until you actively drive it low) and the SPI bus pins (pull-up resistors can provide known states when the bus is not active). However, it's recommended to always reference the specific requirements from your datasheet.

Do ask if assistance is required in interpreting the datasheet once you have it to hand.
