XC95144XL-10CSG144C

Complex Programmable Logic Devices Overview

The XC95144XL-10CSG144C 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 utilizes Flash memory technology for non-volatile configuration and supports In-System Programming (ISP) via IEEE-1149.1 JTAG. Key electrical parameters include a maximum propagation delay of 10 ns, a maximum operating frequency of 178 MHz, and an operating voltage range of 3.0 V to 3.6 V. It is housed in a 144-pin CSBGA package.

Complex Programmable Logic Devices Feature Summary

• Flash-based non-volatile architecture with >10,000 erase/write cycles and 20-year data retention.
• High-speed performance with 10 ns max propagation delay and 178 MHz internal clock capability.
• Supports 5V tolerant inputs for compatibility with legacy 5V peripherals while operating at 3.3V.
• Integrated bus-hold circuits and input hysteresis to improve noise immunity.

Complex Programmable Logic Devices Applications

• System control and glue-logic replacement.
• I/O buffering and level shifting between different voltage domains.
• State machine implementation and protocol conversion.
• Bus bridging and interface logic in embedded systems.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official datasheets, as standard listings often use 'I' for industrial temperature ranges (-40°C to +85°C). Confirm if 'C' denotes commercial grade (0°C to +70°C) or a specific packaging variant. Check current availability status, as this component may be subject to end-of-life restrictions or obsolescence notices from the manufacturer.

Complex Programmable Logic Devices Selection Notes

Select this model when 144 macrocells are required for complex logic functions in space-constrained designs. The CSBGA package offers high pin density suitable for surface-mount applications. Ensure the design accounts for the 3.3V core voltage and verify that the 10 ns speed grade meets the timing constraints of the target application. Consider the 5V tolerant I/O feature if interfacing with older 5V logic families.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, which succeeded the original XC9500 line by integrating Flash memory to eliminate the need for external configuration devices. The XC95144XL variant specifically provides 144 macrocells, balancing logic capacity with power efficiency. It is distinct from FPGA families like Spartan or Virtex, offering deterministic timing and lower static power consumption for fixed logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include XC95144XL-10CSG144I for industrial temperature range or XC95144XL-10TQ144 variants for TQFP packages. Verify pinout compatibility when switching between CSBGA and TQFP packages. Cross-reference with XC95144-10 series if Flash features are not strictly required, though architectural differences exist.
