ISPLSI 2064VE-200LJ44

Complex Programmable Logic Devices Overview

The Lattice ispLSI2064VE-280LJ44 is a high-density, 3.3V in-system programmable logic device (PLD) from the ispLSI 2000E family. It features 2000 PLD gates, 64 macrocells, and 32 I/O pins housed in a 44-pin PLCC package. The device utilizes E2CMOS technology to achieve a maximum operating frequency of 280 MHz with a propagation delay of 3.5 ns. It supports non-volatile reprogrammability via IEEE 1149.1 boundary scan and offers 5V tolerant I/O for mixed-voltage system compatibility.

Complex Programmable Logic Devices Feature Summary

• High-performance SuperFAST architecture with 280 MHz fmax and 3.5 ns tpd
• In-system programmability using Boundary Scan Test Access Port (TAP)
• 5V tolerant I/O allowing direct interface with standard 5V TTL devices
• Programmable open-drain outputs for flexible bus arbitration

Complex Programmable Logic Devices Applications

• Complex state machine implementations
• Address decoding and counter circuits
• Mixed-voltage system bridging
• Bus arbitration logic

Complex Programmable Logic Devices Procurement Notes

Verify that the ordering suffix LJ44 corresponds specifically to the 44-pin PLCC package variant. Confirm the speed grade matches the required timing constraints, as the datasheet lists multiple performance options within the same logical family. Ensure design tools support the specific E2CMOS programming requirements for this legacy component series.

Complex Programmable Logic Devices Selection Notes

Select the -280 speed grade when designs require maximum toggle frequencies up to 280 MHz. Choose the 32-I/O version if pin count optimization is necessary, noting it shares the same gate density as the 64-I/O variant. Consider the 5V tolerance feature if interfacing directly with older 5V logic families without level shifting components.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000E family, which integrates the density of FPGAs with the ease of use of traditional PLDs. It succeeds earlier versions like the ispLSI 2064V, offering improved speed and lower power consumption through advanced E2CMOS technology while maintaining functional and pinout compatibility.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly states the device is 100% functionally and pinout compatible with the ispLSI 2064V series. Designers migrating from the V-series can utilize this part as a drop-in replacement to gain higher performance speeds without altering board layout or logic configuration.
