ISPLSI2192VL-100LT128

Overview

The ISPLSI2192VL-100LT128 is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 2000VE family. It features 96 macrocells, 4000 usable gates, and 96 I/O pins within a 128-pin TQFP package. The device supports in-system programming via EEPROM technology and operates at a maximum frequency of 100 MHz with a typical propagation delay of 10 ns. It functions on a single 5V supply voltage and includes JTAG interface capabilities for boundary scan testing.

Feature Summary

• High-density architecture with 96 macrocells and 4000 gates
• In-system programmability using non-volatile EEPROM technology
• Supports JTAG boundary scan for manufacturing test coverage
• Single 5V power supply operation

Applications

• System logic replacement
• Address decoding
• Bus bridging

Part Context

This component belongs to the ispLSI 2000VE series, designed for high-performance applications requiring dense logic in standard packages. The 'VL' suffix indicates a specific speed grade or variant within the 100 MHz operational class, while 'LT128' specifies the Lead-free 128-pin Thin Quad Flat Package.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the ispLSI 2000VE family, such as the ISPLSI2192V-100LT128, provided timing requirements are met. Designers should verify that the alternative part number maintains the same macrocell count and I/O configuration.
