Xilinx QPro XQR17V16

The Function and Applications of Xilinx QPro XQR17V16 Series

Xilinx introduced the highly-flexible programmable QPro XQR17V16 series. This series offers a cost-effective and easy-to-use method to store large bitstreams. Xilinx is a well-known company that designs FPGAs and programmable SoCs for different applications. The devices designed by this company are ideal for use in several industries.

Memory is a crucial component of the field-programmable gate arrays (FPGAs) utilized in wireless devices. Therefore, the PROMs are one of the memory additions for FPGA configuration. The QPro XQR17V16 series offers high-end programmable logic solutions. It is one of the most popular series developed by Xilinx. Therefore, in this article, we will discuss it more.

Xilinx QPro XQR17V16 Series – What is it?

The QPro XQR17V16 features a storage capacity of 16 Mbt. Therefore, this device can function in a byte-wide or serial mode. The QPro XQR17V16 series is radiation-hardened. This device is specifically designed on Xilinx QML certified manufacturing lines. PROMs offer the lowest cost per Mb for FPGA configuration storage.

QPro XQR17V16 produces a configuration clock that triggers the PROM. This happens when the FPGA is in Master Serial mode. Data displays on the PROM DATA output pin linked to the FPGA DIN pin. Also, the FPGA produces the right number of clock pulses needed to complete the configuration.

The PROM disables, once the FPGA configures. An incoming signal needs to clock the FPGA and the PROM. This is important when the FPGA is in Slave Serial mode. The FPGA produces the configuration clock that drives the FPGA and PROM. This happens anytime the FPGA is in Master SelectMAP mode.

Data becomes available on the PROMs DATA (D0-D7) pins after the CCLK edge rises. Furthermore, an incoming signal must clock the FPGA and the PROM. This is important whenever the FPGA is in Slave SelectMAP mode. A free running oscillator can drive the CCLK.

You can connect many devices by utilizing the CEO output to drive the CE input of the next device. Also, the DATA outputs and clock inputs of PROMs in this chain are well-interconnected. All devices can be fully cascaded with other devices in the family.

Xilinx QPro XQR17V16 complies with the IEEE1532 interface. Therefore, designers can program and test them using existing equipment. Designers can program several designs into a single PROM. Also, one PROM can support several FPGAs in a daisy-chain configuration. Therefore, this leads to reduced component costs and part count.

Pin Description of Xilinx QPro XQR17V16 Series

There are several pins on the Xilinx QPro XQR17V16 Series. Each of these pins has its unique functions. These pins contribute to the following.

CEO

This refers to the Chip Enable Output. The CEO is specifically connected to the CE input of the PROM. The CEO is low when the OE and CE inputs are active. Also, the output will be low when the Internal Address Counter increments more than its TC value. The TC value means Terminal Count value. Therefore, when the PROM reads, CEO will go along with CE if OE remains active. It is important to know that OE can be active-Low or active-High.

RESET/OE

The RESET/OE is another important pin of the Xilinx QPro XQR17V16 Series. When the RESET/OE is high, the input keeps the address counter reset. Also, the DATA output is in a high-impedance state. The input pin polarity is programmable as OE/RESET or RESET/OE. The address counter is “0” when RESET is active. This puts the DATA output in a state of high impedance.

The preferred option of the device is active-Low RESET. However, the device default is active-High RESET. This is because it can connect to a pullup resistor and the FPGAs INIT pin. Furthermore, the programmer interface controls the polarity of this pin. The Xilinx HW-130 programmer helps to invert the input pin. However, there are different ways third-party programmers invert this pin.

Vpp

The Vpp is the programming voltage. This pin doesn’t allow overshoot beyond the specified maximum voltage. You must connect this pin to Vcc for normal read operation. Otherwise, this will result in temperature-dependent operation. Also, it can lead to severe issues in circuit debugging. It is dangerous to leave the Vpp floating. Therefore, avoid this.

CE

This pin can disable the internal address counter when it is high. Also, the CE will put the DATA output in a state of high impedance. It will make the device forcefully go into low-lcc standby mode.

CLK

Every rising edge on the CLK input increases the internal address counter. This happens when OE and CE are both active.

BUSY

If this pin isn’t floating, the user has to program the BUSY bit. This will make this pin to be internally attached to a pull-down resistor. Output data holds when the BUSY pin is high. When the pin becomes low, the data output will continue.

DATA [0:7]

When OE or CE isn’t active, data output is in a state of high impedance. The D0 pin is I/O during the programming. OE can either be active Low or active High.

How the FPGA Master Serial Mode Works

A configuration program establishes the logic and I/O functions of the CLB and their interconnections. This program loads in command or automatically. However, this depends on the condition of the three FPGA mode pins. The FPGA loads the configuration program automatically from an external memory. This happens in the Master Serial mode. The PROMs are specifically designed to be compatible with this mode.

If powered-up or reconfigured, an FPGA goes into the Master Serial mode. Also, this happens when all three FPGA mode select pins are Low. Data is sequentially read form the PROM on a single data line. The rising edge of the CCLK provides synchronization generated during configuration.

The Master Serial Mode offers a simple interface for configuration. For an FPGA configuration, a serial data line, a clock, and two control lines are vital. Data from PROM sequentially read. Also, you can access data through the bit counters and internal address.

The dual-function DIN pin on the FPGA must be at a defined level during normal operation. This is important if the pin is used for configuration only. The on-chip default pull-down/up resistor will automatically take care of this.

How to Cascade Configuration PROMs

The cascaded PROMS offer additional memories. These memories are ideal for several FPGAs that need bigger configuration memories. The next clock signal to the PROM declares its CEO output Low after reading the last bit from the first PROM. Also, this disables its DATA line.

The address counters of cascaded PROMS will reset after completing the configuration. However, this happens when the FPGA program pin becomes Low. Anytime CE is high, the PROM goes into a low-power standby mode. The output will be in a state of high impedance irrespective of the OE input.

How to Connect the FPGA device with the PROM

  • For serial mode, the PROM’s D[O] output(s) drives the Din input of the FPGA device.
  • The PROM’s CEO output drives the next PROM’s CE input.
  • For parallel mode, the PROM’s D[0-7] outputs drive the D[0-7] data inputs.
  • Connect the PROM CE input to the DONE pin of the FPGAs. Also, CE can be permanently Low. However, this makes the DATA output active. Therefore, it results in an unnecessary supply of 15 mA maximum.
  • The FPGA’s CCLK pin must connect to the PROM’s CLK input. The external clock source connection is necessary when all FPGAs are presently in a slave configuration mode. Also, only an FPGA is in a master configuration mode when you use a master configuration mode. Therefore, the clock signal is driven by the master mode. Other FPGAs will remain in a slave configuration mode.
  • SelectMAP mode works like the Slave Serial mode. The DATA clocks out of the PROM one byte for each CCLK.
  • The INIT output of the FPGA should drive the RESET/OE input of all PROMs. Therefore, this connection guarantees that the PROM address counter resets before any reconfiguration.
