Ordinarily, a Complex Programmable Logic Device (CPLD) may pass for a Programmable Logic Array (PLA) because of the connection format.
However, a CPLD, as the name signifies, is more complex than a traditional PLA. If you are looking to invest in one, consider the Xilinx XC2C32A-6QFG32I. Manufactured by Xilinx, it is optimized for low-power and high-performance applications.
In this article, we discuss the technical specifications of the chip. We also cover the buying guide/the things to look for before buying the Xilinx XC2C32A-6QFG32I. Finally, we compared the Xilinx XC2C32A-6QFG32I to a Field Programmable Gate Array (FPGA).

Xilinx XC2C32A-6QFG32I Buying Guide
No doubt that the Xilinx XC2C32A-6QFG32I is one of the high-performance and low-power Complex Programmable Logic Devices (CPLDs).
However, to be on the safer side, consider checking out some things before you place your order. Here is a list of some of the things you want to check before ordering for the Xilinx XC2C32A-6QFG32I CPLD:
1. Capability of the I/O
The Input and Output (I/O) is one of the most important factors to consider. It deals on the number of pins used in configuring the chip.
For emphasis, you want to concentrate on specific aspects of the I/O’s capabilities. Here are some of the areas of concentration.
The type of logic is worth considering. This is so because its capability should be able to increase the overall functionality of the chip’s design.
The next thing to look into (as per the I/O) is the independence of the I/O. We must mention that not all I/Os are independent. Some need to be tied to the master reset and clock input as dedicated I/Os to help their operations.
The output capability of the I/Os is another important factor to consider. It has to do with the current and voltage levels supported by the I/O.
2. Programming Technology
What type of programming technology is required to configure the Xilinx XC2C32A-6QFG32I CPLD?
The programming technology helps determine the number of configurations due for the chip.
The most popular programming technologies are:
- Flash EPROM
- EPROM
- EEPROM
3. The Function Block’s Capability
What can the Function Block do towards the improvement of the Xilinx XC2C32A-6QFG32I design?
The things to look into here include the minimum and maximum propagation delay timeframes (in nanoseconds) for the Function Block.
You also want to check the number of Function Blocks in the Xilinx XC2C32A-6QFG32I CPLD and whether these Function Blocks have any need for additional logic resources.
Xilinx XC2C32A-6QFG32I vs FPGA
Xilinx XC2C32A-6QFG32I CPLD has some advantages over a Field Programmable Gate Array (FPGA).
Here are some of them:
- Xilinx XC2C32A-6QFG32I CPLD’s memory architecture is persistent, meaning that it doesn’t wipe out the memory even if the device shuts down. This is unlike most FPGAs that use the SDRAM memory that clears data once the circuit is off.
- Xilinx XC2C32A-6QFG32I propagation delay is more predictable than that of an FPGA. Most FPGAs propagation delays are unpredictable because of the reconfigurable design of the circuit.
- Last but not least, Xilinx XC2C32A-6QFG32I’s CPLD is a competitive option to an FPGA because it has a lower development cycle. Therefore, it will hit the market faster than an FPGA would.
