LA4064V-75TN100E

Overview

The LA4064V-75TN100E is an automotive-grade Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 64 macrocells, 4 Logic Array Blocks (LABs), and 64 I/O pins housed in a TQFP-100 package. The device operates at a maximum frequency of 168 MHz with a maximum propagation delay of 7.5 ns. It supports a supply voltage range of 3.0 V to 3.6 V, drawing approximately 12 mA of operating current. Certified under AEC-Q100 standards, it ensures reliability for automotive applications across an extended temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive electronics reliability
• High performance with 168 MHz max frequency and 7.5 ns propagation delay
• 64 macrocells organized into 4 LABs within a TQFP-100 package
• Extended industrial temperature operation from -40°C to +125°C

Applications

• Automotive body control modules
• Instrument cluster logic
• Infotainment system interfaces
• Sensor signal conditioning

Procurement Notes

Verify component authenticity through authorized Lattice distributors or certified suppliers. Confirm AEC-Q100 certification status via official datasheets. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure packaging integrity matches tray specifications for surface-mount technology processes.

Selection Notes

Select this model when automotive qualification is mandatory for CPLD designs requiring 64 macrocells. Compare against LC4064V variants if industrial temperature range (-40°C to +105°C) suffices instead of extended automotive grades. Verify pin count compatibility with TQFP-100 footprints and ensure power supply constraints align with the 3.3 V nominal requirement.

Part Context

This part belongs to the Lattice ispMACH 4000V family, specifically designed for high-density, low-power programmable logic. The 'LA' prefix denotes automotive-grade qualification, distinguishing it from commercial 'LC' series parts. It serves as a drop-in replacement for legacy GAL devices in automotive systems requiring reprogrammability.

Replacement Considerations

Direct functional equivalents include the LC4064V-75TN100I for non-automotive applications. For higher density needs, consider the LA4128V-75TN100E which offers 128 macrocells in the same package.
