1. General Introduction

The XC95144XL - 10TQG144C is a Complex Programmable Logic Device (CPLD) from Xilinx. CPLDs are integrated circuits that can be programmed by the user to perform specific digital logic functions. They are widely used in various electronic systems to implement custom logic designs.

2. Key Features

2.1 Logic Capacity

The “144” in the part number XC95144XL indicates its logic capacity. It has 144 macrocells, which are the basic building blocks for implementing logic functions. These macrocells can be configured to perform a wide variety of combinational and sequential logic operations, allowing designers to create complex digital circuits such as state machines, counters, and decoders.

2.2 Low - Power Operation

The “XL” in the part number represents the low - power version of the XC9500 series. The XC95144XL - 10TQG144C is designed to consume less power compared to non - XL versions. This is beneficial for battery - powered devices or applications where power efficiency is a priority, as it helps to extend the battery life and reduce heat generation.

2.3 High - Speed Performance

The “- 10” in the part number indicates the speed grade. A speed grade of 10 implies that the CPLD has a relatively high - speed performance. It can operate at a fast clock frequency, enabling it to handle high - speed digital signals and perform logic operations quickly. This is important in applications such as high - speed data communication, signal processing, and real - time control systems.

2.4 Package Type

The “TQG144” represents the package type. It comes in a 144 - pin Thin Quad Flat Pack (TQFP) package. The TQFP package is a surface - mount package that offers a relatively small form factor and good thermal performance. It is suitable for applications where space is limited, such as in portable electronics and small - sized printed circuit boards (PCBs).

2.5 In - System Programmability (ISP)

The XC95144XL - 10TQG144C supports in - system programmability. This means that the device can be programmed or reprogrammed while it is installed on the PCB, without the need to remove it. ISP simplifies the development process and allows for easy updates and modifications to the logic design in the field.
