ISPLSI 2064A-100LTN100

Complex Programmable Logic Devices Overview

The Lattice ISPLSI2064A-100LTN100 is a high-density, in-system programmable logic device (PLD) from the ispLSI 2000AFamily. It features 2000 PLD gates, 64 macro cells, and 64 I/O pins within a 100-pin lead-free TQFP package. Built on 0.35 micron E2CMOS technology, it operates at a maximum frequency of 100 MHz with a propagation delay of 10 ns. The device supports 5V in-system programming, offers non-volatile reprogrammability, and includes three dedicated clock inputs and two global output enable pins for flexible system design.

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 2000 PLD gates, 64 registers, and 64 universal I/O pins.
• Performance: Achieves fmax = 100 MHz and tpd = 10 ns using advanced 0.35 micron E2CMOS technology.
• In-System Programmability: Supports ISP via 5V supply only, allowing reprogramming of soldered devices.
• Flexible Clocking: Features three dedicated clock input pins (Y0, Y1, Y2) and asynchronous clock options.

Complex Programmable Logic Devices Applications

• Complex glue logic replacement in digital systems
• State machine implementation
• Address decoding and counter circuits
• Interface bridging between different voltage domains

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or Lattice Semiconductor directly. Check for moisture sensitivity level (MSL) handling requirements, particularly for the lead-free TQFP package. Confirm that the specific speed grade (-100) matches the timing constraints of the target application. Ensure programming tools support the ispLSI 2000A family for in-system programming.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 I/Os and 2000 gates are required with 10 ns propagation delay. Compare against the -80 speed grade if lower performance is acceptable for power savings. Consider the -125 grade for higher speed needs. Ensure the design utilizes the 5V ISP capability. Verify pin compatibility if replacing older ispLSI 2064 variants, as they are functionally identical.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispLSI 2000A family, which is fully form and function compatible with the original ispLSI 2064. It represents an enhancement built on 0.35 micron technology. New designs are recommended to use the ispLSI 2064E series instead. The -100 suffix denotes the 100 MHz speed grade, while LT indicates the 100-pin TQFP package, and N signifies lead-free construction.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2064-100LT is functionally equivalent but lacks the 'A' designation. For new designs, consider the ispLSI 2064E series. Direct pin-compatible replacements from other manufacturers are not explicitly listed in the provided documentation; verify cross-reference data separately.
