ISPLSI2192VL-100LB144

Overview

The ISPLSI2192VL-100LB144 is a high-performance Complex Programmable Logic Device (CPLD) from the ispLSI 2000 family, manufactured by Lattice Semiconductor. It features 256 macrocells and operates with a maximum propagation delay of 10 ns. The device supports a supply voltage range of 3.0 V to 3.6 V and includes 144 I/O pins in a 208-pin PQFP package. Key specifications include a typical standby current of 15 mA and support for JTAG in-system programming.

Feature Summary

• 256 macrocells with 10 ns maximum propagation delay
• 144 I/O pins in a 208-pin PQFP package
• Supports JTAG in-system programming
• Operating voltage range of 3.0 V to 3.6 V

Applications

• High-speed digital logic interfacing
• Address decoding and bus bridging
• State machine implementation
• Logic replacement for discrete gate arrays

Procurement Notes

Verify the specific suffix 'VL' indicates the industrial temperature grade (-40°C to +85°C). Confirm the '100' speed grade matches the required 10 ns timing constraints. Ensure the 208-pin PQFP footprint aligns with the target PCB design. Check for RoHS compliance status as manufacturing processes evolve.

Selection Notes

Select this component when 256 macrocells are sufficient for the design complexity. The 10 ns speed grade is suitable for moderate-frequency applications. Consider the 208-pin package size relative to available board space. Compare against the ispMACH 4000V series if lower power consumption or higher density is required.

Part Context

This part belongs to the legacy ispLSI 2000 family, which established foundational CPLD architectures. It serves as a bridge between older GAL replacements and modern FPGA solutions. While newer families like MachXO3 offer higher density, this device remains relevant for cost-sensitive, low-volume designs requiring proven reliability.

Replacement Considerations

Direct pin-to-pin replacements may not exist due to architectural differences. Evaluate the ispLSI 2192VE for similar performance with potential package variations. For migration to newer technologies, consider the ispMACH 4000V/Z family for enhanced routing resources and lower power characteristics.
