ISPLSI2064VL-100LT100

Overview

The ISPLSI2064VL-100LT100 is a Complex Programmable Logic Device (CPLD) belonging to the ispLSI 2000AFamily. It features 2K system gates and 64 macro cells, providing a logic density suitable for moderate complexity digital designs. The device supports a maximum operating frequency of 81 MHz and operates with a standard 5V supply voltage. It is housed in a 100-pin Thin Quad Flat Package (TQFP), offering 72 I/O lines for system connectivity. This component utilizes In-System Programmability (ISP) technology, allowing configuration updates without removal from the circuit board.

Feature Summary

• ispLSI® 2000A architecture with 2K Gates and 64 Macro Cells
• In-System Programmability (ISP) capability
• Supports JTAG boundary scan testing
• Operating temperature range includes commercial and industrial grades

Applications

• General-purpose digital logic replacement
• Address decoding and bus interfacing
• State machine implementation
• Protocol conversion interfaces

Procurement Notes

Verify the specific suffix 'LT100' against official Lattice documentation to confirm the package type and temperature grade. Ensure compatibility with the design tool version used for ispLSI 2000A devices. Check RoHS compliance status as older variants may differ from current manufacturing standards.

Selection Notes

Select this model when a 5V supply is required and 64 macro cells are sufficient for the design. Compare pin counts with the LT44 variant if space is constrained. Verify that the 100-pin TQFP footprint matches the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the legacy ispLSI 2000A family, which was widely used before the transition to the MachXO and ECP series. It serves as a drop-in replacement for older GAL or PAL devices in existing systems requiring higher logic density.
