LA4128V-75TN144E

Overview

The LA4128V-75TN144E is an automotive-grade Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispMACH 4000V family. It features 128 macrocells and 96 I/Os within a 144-pin TQFP package. The device supports In-System Programming via JTAG and operates on a 3V to 3.6V supply voltage. Key electrical parameters include a maximum propagation delay of 7.5 ns, a maximum operating frequency of 333 MHz, and a junction temperature range of -40°C to 125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for high reliability in vehicle environments.
• Supports 5V tolerant I/O interfaces including LVCMOS 3.3, LVTTL, and PCI, enabling direct interfacing with legacy systems.
• Features a 1.8V core voltage architecture to minimize dynamic power consumption while maintaining SuperFAST performance.

Applications

• Automotive infotainment system logic control
• Body control module interface adaptation
• Industrial sensor signal conditioning

Part Context

This component belongs to the ispMACH 4000V series, which integrates the ispLSI 2000 and ispMACH 4A architectures. The 'LA' prefix specifically denotes the automotive grade variant, offering extended temperature support and enhanced durability compared to standard commercial versions like the LC4128V.

Replacement Considerations

The LC4128V-75TN144I is a commercial-grade equivalent within the same family. While it shares identical logical density and pinout, it lacks AEC-Q100 certification and has a lower maximum junction temperature rating (-40°C to 105°C). Verify thermal requirements before substitution.
