LC4064V-25TN100C

Complex Programmable Logic Devices Overview

The LC4064V-25TN100C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 64 macrocells and supports up to 64 I/Os in a 100-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 2.5 ns. It utilizes a 3.3 V core voltage for low dynamic power consumption while maintaining 5 V compatible I/Os. The component supports In-System Programming via JTAG and is rated for industrial temperature ranges.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells with SuperFast performance up to 400 MHz
• 5 V tolerant I/Os supporting LVCMOS 3.3, LV TTL, and PCI interfaces
• In-System Programmability (ISP) via JTAG interface
• 100-pin Thin Quad Flat Package (TQFP) with 0.5 mm pin pitch

Complex Programmable Logic Devices Applications

• High-speed data acquisition systems
• Protocol conversion and bus bridging
• Address decoding and logic replacement
• Industrial control logic

Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'C' indicates the commercial temperature grade (0°C to +70°C or similar depending on specific datasheet revision) versus the 'I' industrial grade. Confirm RoHS compliance status as manufacturing processes evolve. Ensure ESD precautions are taken during handling due to CMOS technology sensitivity.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design logic density. The 25 speed grade offers a balance between performance and power. Compare against LC4064V-5TN100I if higher operating temperatures (-40°C to +85°C) are required. Verify that the 100-pin TQFP footprint matches the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V series, which integrates architecture from previous ispLSI 2000 and ispMACH 4000 devices. The 'V' denotes the 3.3 V core voltage variant, distinct from the 2.5 V (B) or 1.8 V (C/Z) core variants within the broader 4000 family.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents include other parts in the LC4064V series with different speed grades or temperature ratings, such as LC4064V-5TN100I. Cross-family migration to LC4064Z may require voltage level adjustments.
