What is the EPCS128SI16N used for? The EPCS128SI16N is used for storing configuration data (bitstreams) for FPGAs and providing non-volatile storage for the FPGA system.
How many pins does the EPCS128SI16N have? The EPCS128SI16N comes in a 16-pin SOIC package.
What is the voltage supply for the EPCS128SI16N? The device typically operates with a 3.3V power supply (VCC pin).
Can the EPCS128SI16N be used in a 5V system? No, the EPCS128SI16N is designed to operate at 3.3V. Using it in a 5V system could damage the device.
What is the maximum frequency supported by the EPCS128SI16N? The maximum clock frequency for this device depends on the FPGA configuration, typically up to 50 MHz for serial communication.
What does the CS pin do on the EPCS128SI16N? The CS pin is the Chip Select input, which, when low, enables communication with the device.
What is the function of the MOSI and MISO pins? MOSI is for data input from the FPGA (Master Out Slave In), and MISO is for data output to the FPGA (Master In Slave Out).
What is the role of the CLK pin on the EPCS128SI16N? The CLK pin is used to clock the data in and out of the device during serial communication.
How do I reset the EPCS128SI16N? The RESET pin should be driven low to reset the device to its initial state.
What does the DONE pin indicate? The DONE pin signals that the FPGA configuration is complete and that the device has finished its programming cycle.
What is the function of the WE pin on the EPCS128SI16N? The WE pin enables write operations to the memory of the device when low.
What does the OE pin control? The OE pin controls whether the data pins are active or tri-stated. When low, the data pins are active; when high, they are in a high-impedance state.
What is the AS pin used for? The AS pin is the Address Strobe, used to indicate when the address for a read operation is valid.
How is data read from the EPCS128SI16N? Data is read by activating the appropriate control signals (CS, CLK, and AS) to initiate the read cycle.
What is the RDY pin used for? The RDY pin indicates when the device is ready to perform a new operation.
Can the EPCS128SI16N be used with any FPGA? Yes, the EPCS128SI16N is compatible with a wide range of Intel (Altera) FPGAs for configuration storage.
What is the VCCIO pin used for? The VCCIO pin powers the I/O circuitry of the EPCS128SI16N, typically matching the voltage of the FPGA I/O supply.
What does the BYTE pin control? The BYTE pin is used to configure the data bus width for the device (8-bit or 16-bit data).
**What happens if the *INT* pin is used?** The INT pin allows the device to signal an interrupt to the FPGA or processor for asynchronous operations.
**Is the *EPCS128SI16N* compatible with any specific software tools?** Yes, the EPCS128SI16N is supported by Intel Quartus and other FPGA development tools for programming and configuration.
