ISPLSI 2064VE-100LTN100

Complex Programmable Logic Devices Overview

The ispLSI 2064VE-100LTN100 is a high-density, 3.3V in-system programmable PLD from Lattice Semiconductor. It features 2000 PLD gates, 64 I/O pins, and four dedicated inputs within a lead-free 100-pin TQFP package. The device utilizes E2CMOS technology to achieve a maximum operating frequency of 100 MHz with a propagation delay of 10 ns. Key architectural elements include 64 registers, three dedicated clock inputs, two global output enable pins, and a Global Routing Pool for complete interconnectivity between Generic Logic Blocks.

Complex Programmable Logic Devices Feature Summary

• High-performance E2CMOS technology enabling 100 MHz operation and 10 ns propagation delay
• In-system programmability via IEEE 1149.1 Boundary Scan Test Access Port (TAP)
• Non-volatile reprogrammability of logic and interconnect structures
• TTL-compatible I/O levels supporting mixed-voltage system interfaces

Complex Programmable Logic Devices Applications

• Complex state machine implementations requiring fast counters or address decoders
• Bus arbitration logic utilizing open-drain output configurations
• Mixed-voltage interface bridging between 3.3V and 5V TTL devices
• Prototyping systems requiring on-board reconfiguration without desoldering

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix 'TN' confirms lead-free packaging compliance as specified in the datasheet. Ensure the design environment supports the specific 100-Pin TQFP footprint dimensions. Confirm that the target application operates within the commercial temperature range defined for this speed grade.

Complex Programmable Logic Devices Selection Notes

Select this component when a non-volatile PLD with 64 I/Os and 100 MHz performance is required. The -100 speed grade offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the -280 grade if higher frequencies are needed, or the -135 grade for lower power requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2000VE family, which provides enhanced pin locking and flexible clocking options compared to previous generations. It maintains functional and pinout compatibility with the standard ispLSI 2064V series while offering improved speed and 3.3V operation capabilities.

Complex Programmable Logic Devices Replacement Considerations

The standard ispLSI 2064VE-100LT100 serves as a direct functional replacement, differing only in the absence of the lead-free designation. Other speed grades within the same package may be substituted if timing constraints allow.
