What is XC9572XL?

The Xilinx XC9572XL has pin-to-pin logic delays of 5 ns. This device's system frequency is also approximately 178 MHz. 1,600 useable gates are available across 72 macrocells in the Xilinx XC9572XL design. This gadget is designed to operate at peak efficiency on 3.3V systems. It thereby provides Fast FLASHTM technology and low-power operation.

Xilinx XC9572XL fully supports IEEE standard 1149.1 boundary-scan (JTAG). This makes it possible to create and debug small-footprint packages more effectively. Additionally, each macrocell may operate on minimal power thanks to this device. Consequently, this makes it possible to reduce gadget power drastically. The user can set each macrocell to operate in low power mode.

Figure1-XC9572XL family

To be compatible with Spartan-XL and Xilinx Virtex, the Xilinx XC9572XL family was created specifically. As a result, this gives system designers the best possible separation of logic between quick interface circuitry and high-density general-purpose logic. The XC9572XL series is pin-compatible as well. This facilitates the migration of design across many density possibilities within a given package footprint.

The XC9572XL device has multiple function blocks and I/O blocks. It is a subsystem, this gadget. Buffering for device outputs and inputs is provided via the I/O block. Every functional block (FB) can use programmable logic. Furthermore connecting all input signals and FB outputs to the FB inputs is the FastCONNECT II switch matrix.

How to minimize power dissipation in Xilinx XC9572XL CPLD?

Power dissipation in CPLDs can vary significantly depending on the output loading and system frequency. Design applications can also determine power dissipation. Each macrocell in the Xilinx XC9572XL CPLD can be set up to operate in low power mode. In doing so, power dissipation is reduced. Moreover, macrocells and unused product keywords are immediately deactivated by the software. As a result, this promotes energy conservation.

You can use the following equation for an estimate of Icc.

ICC(mA) = MCHS(0.175*PTHS + 0.345) + MCLP(0.052*PTLP + 0.272) + 0.04 * MCTOG(MCHS +MC)

Here:

• The term "MCHS" describes the high-speed configuration of macrocells.
• The macrocells in low power configuration, or MCLP for short,
• f refers to the maximum clock frequency
• PTLP refers to the average number of low-power product terms for each macrocell
• PTHS refers to the average number of high-speed product terms for each macrocell
• MCTOG refers to the average % of flip-flops per clock

The Architectural Description of XC9572XL

Several units make up the Xilinx XC9572XL.

Function block (FB)

Each function block is made up of separate macrocells. Global clock, reset/set, and output enable signals are also received by the function block. The outputs generated by this block support the FastCONNECT switch matrix. Using a sum-of-products representation facilitates the application of FB's logic.

Macrocell

It is possible to individually configure each macrocell in XC9572XL for a combinatorial or registered function. The macrocell register can be set up as a D-type or T-type flip-flop. Additionally, it is avoidable for combinatorial operations. Set and reset operations can be performed asynchronously on any register.

FastCONNECT II switch matrix

Signals are connected to the function block inputs in this way. This matrix is driven by all of the functional block and I/O block outputs.

Input/output block

The I/O Block, also called the IOB, serves as an interface between internal logic and the device's user I/O pins. An output driver and an output enable selection multiplexer are included with each IOB. Additionally, each IOB has an input buffer and user-programmable ground control.

User-programmable ground pin capability is available on all IOBs. Consequently, you can set up device I/O pins as extra ground pins thanks to this. Unused pins will be forced to a low-voltage state as a result. Every I/O block has bus-hold circuitry that is always operational when there is legitimate user activity. Furthermore, there's no need to bind unneeded pins high or low because of the bus-hold property.

Every output driver has the option to be configured for slew-rate limited operation. All output drivers are capable of providing low-power noise and quick switching. Grounding capability may be present in all output drivers. This is something internal logic can accomplish. An essential component of the FPGA of the Xilinx XC9572XL series is the IOB.
