XC95144XL-7TQG144C

Complex Programmable Logic Devices Overview

The XC95144XL-7TQG144C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, designed for 3.3V low-voltage systems. It features 144 macrocells and approximately 3,200 usable gates organized into eight Function Blocks. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports an internal system frequency up to 178 MHz. Key electrical parameters include a maximum propagation delay of 7.5 ns and a typical operating current of 45 mA. It utilizes Flash memory technology for non-volatile configuration and supports in-system programming via JTAG.

• Protocol front-end processing for serial and parallel data transmission.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number may be sourced through secondary distributors like Rochester Electronics. Confirm RoHS compliance status and moisture sensitivity level (MSL) handling requirements prior to assembly. Check for specific ordering suffixes that may indicate temperature grade or package variant variations.

Complex Programmable Logic Devices Selection Notes

Select this model when a moderate density CPLD with fast I/O response is required for 3.3V applications. Ensure the design fits within the 144 macrocell limit and consider the 7.5 ns propagation delay for timing closure. Verify that the TQFP-144 package dimensions fit the PCB layout constraints compared to BGA alternatives.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, which succeeded the original XC9500 line by offering lower power consumption and higher performance. It serves as a bridge between simple PLDs and complex FPGAs, providing reprogrammability without the overhead of SRAM-based FPGA configuration. The 'XL' designation indicates enhanced speed and density improvements over earlier generations.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other XC95144 variants with different speed grades (e.g., XC95144XL-10TQG144C) or packages. Cross-family migration to Lattice LC4000 or Microchip MAX3000 series requires schematic and code adaptation due to architectural differences in macrocell organization and I/O structures.
