ISPLSI2064VL-135LT100

Overview

The ISPLSI2064VL-135LT100 is a Complex Programmable Logic Device (CPLD) belonging to the Lattice ispLSI® 2000AFamily. It features 2,000 system gates and 64 macro cells, providing sufficient logic density for moderate complexity digital designs. The device supports a maximum operating frequency of approximately 74 MHz and operates with a standard 5V supply voltage. It is housed in a 100-pin Thin Quad Flat Package (TQFP), facilitating surface-mount assembly on printed circuit boards.

Feature Summary

• ispLSI® 2000A architecture with 2K Gates and 64 Macro Cells
• System performance up to 74 MHz at 5V operation
• In-system programmability via JTAG interface
• CMOS technology ensuring low power consumption

Applications

• Protocol conversion and bridging between different bus standards
• Address decoding and memory mapping in embedded systems
• State machine implementation for industrial control logic
• General-purpose digital logic replacement for legacy TTL/CMOS circuits

Procurement Notes

Verify the specific suffix 'LT100' corresponds to the 100-pin TQFP package and commercial temperature grade. Confirm that the 'L' variant meets the required voltage specifications compared to non-L versions. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability for production use.

Selection Notes

Select this model when a design requires more than 1,000 gates but less than 10,000 gates. It is suitable for applications needing in-system programming capabilities without the complexity of FPGA tools. Compare against the ISPLSI2064A series if higher speed or different packaging options are not critical.

Part Context

This part belongs to the Lattice ispLSI 2000A family, which utilizes high-density E²CMOS technology. This family was designed to replace complex discrete logic and GAL devices, offering reprogrammability and higher integration levels than previous generations like the ispLSI 1000 series.

Replacement Considerations

Direct pin-to-pin replacements within the same package may include other variants of the ISPLSI2064 family with different speed grades or temperature ranges. Verify electrical compatibility before substituting.
