ISPLSI 2064E-200LT100

Complex Programmable Logic Devices Overview

The ispLSI 2064E-200LT100 is a high-density, in-system programmable logic device from Lattice Semiconductor. It features 2000 PLD gates organized into 16 Generic Logic Blocks (GLBs), providing 64 macrocells and 64 universal I/O pins. The device utilizes E2CMOS technology with a maximum operating frequency of 200 MHz and a propagation delay of 4.5 ns. It supports user-selectable 3.3V or 5V I/O levels via VCCIO pins, ensuring compatibility with mixed-voltage systems. The architecture includes three dedicated clock inputs, two global output enable pins, and a Global Routing Pool for complete interconnectivity.

Complex Programmable Logic Devices Feature Summary

• High-performance E2CMOS technology supporting up to 200 MHz operation with 4.5 ns propagation delay.
• In-system programmability via IEEE 1149.1 JTAG interface with non-volatile reprogrammability.
• Flexible I/O configuration allowing selection between 3.3V and 5V supply voltages for mixed-voltage applications.
• Programmable output slew rate control and open-drain output options to minimize switching noise.

Complex Programmable Logic Devices Applications

• Complex glue logic replacement in digital systems.
• State machine implementation requiring high-speed synchronous operations.
• Address decoding and counter circuits utilizing wide input gating capabilities.
• Prototyping and field-upgradable logic designs due to in-system programming support.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-200) corresponds to the required 200 MHz performance specification. Confirm that the LT100 package designation matches the 100-pin TQFP form factor required for the target PCB layout. Ensure design tools support the ispLSI 2064E family for proper JEDEC file generation and programming.

Complex Programmable Logic Devices Selection Notes

Select this component when a high gate count PLD with fast propagation delays is needed. The -200 speed grade is suitable for applications exceeding 135 MHz requirements. Consider the 100-pin TQFP package if surface-mount assembly with fine pitch is feasible. Verify that the system power budget accommodates the typical current consumption calculated based on product term usage and toggle frequency.

Complex Programmable Logic Devices Part Context

This device belongs to the ispLSI 2000E family, which offers upward compatibility with the earlier ispLSI 2064 series. It serves as a bridge between standard PLDs and higher-density FPGAs, providing the ease of use of PLDs with greater density. The 200MHz variant represents the highest speed option within the 2064E lineup, designed for demanding timing constraints.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2064E-135LT100 is a slower variant within the same package and pinout, suitable if 200 MHz performance is not required. Direct functional replacements from other manufacturers are not explicitly documented in the source material; migration typically requires retargeting design files to the new vendor's toolchain.
