ISPLSI 1024EA-200LT100

Complex Programmable Logic Devices Overview

The ispLSI 1024EA-200LT100 is a high-density programmable logic device from Lattice Semiconductor, packaged in a 100-pin Thin Quad Flat Package (TQFP). It features 4000 PLD gates, 144 registers, and 48 universal I/O pins alongside two dedicated inputs. The device utilizes E2CMOS technology to achieve a maximum operating frequency of 200 MHz with a propagation delay of 4.5 ns. It supports user-selectable 3.3V or 5V I/O levels via the VCCIO pin and includes IEEE 1149.1 boundary scan testability for in-system programming.

Complex Programmable Logic Devices Feature Summary

• High-performance E2CMOS technology delivering 200 MHz fmax and 4.5 ns tpd
• User-selectable 3.3V or 5V I/O voltage compatibility via VCCIO pin
• In-system programmability via IEEE 1149.1 JTAG interface
• Programmable open-drain output option and slew rate control

Complex Programmable Logic Devices Applications

• Mixed-voltage system interconnects requiring 3.3V/5V compatibility
• High-speed state machines and address decoders
• Industrial and commercial logic replacement designs

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix LT100 corresponds to the 100-pin TQFP package variant. Confirm the speed grade matches the required 200 MHz performance specification. Ensure design tools support the ispLSI 1024EA family for proper configuration and programming.

Complex Programmable Logic Devices Selection Notes

Select this component when a high gate count PLD with fast propagation delay is required. The -200 speed grade is necessary for designs exceeding 125 MHz. The LT100 package must be chosen if a 100-pin TQFP footprint is mandated by the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 1024EA family, which serves as an enhanced version of the standard ispLSI 1024 architecture. The EA series specifically adds flexible I/O voltage selection and open-drain capabilities compared to its predecessors.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 1024EA-125LT100 offers identical functionality with a lower 125 MHz speed grade. The ispLSI 1024EA-100LT100 provides a 100 MHz alternative. Direct pin-compatible replacements within the same package are limited to these speed variants.
