LA4128ZC-75TN100E

Overview

The LA4128ZC-75TN100E is a complex programmable logic device (CPLD) from the Lattice ispMACH 4000Z family. It features 128 macrocells and supports up to 64 I/Os within a 100-pin TQFP package. The device operates at a maximum frequency of 168 MHz with a propagation delay of 7.5 ns. Designed for automotive applications, it holds AEC-Q100 qualification and functions within a supply voltage range of 3V to 3.6V across an industrial temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• 128 macrocells with 64 I/O pins in a 100-TQFP package
• System-in-programmable capability with JTAG boundary scan support
• High-speed performance: 168 MHz max frequency and 7.5 ns propagation delay

Applications

• Automotive electronic control units (ECUs)
• In-vehicle infotainment systems
• Industrial motor control interfaces

Procurement Notes

Verify the specific suffix 'E' against official Lattice documentation to confirm RoHS compliance status and lead-free manufacturing details. Ensure the ordering part number matches the exact package variant and temperature grade required for the target application environment.

Selection Notes

Select this component when automotive-grade certification is mandatory. Compare the 128 macrocell density against the LC4128ZC series if lower power consumption at 1.8V is prioritized over the 3.3V operation provided by the LA4128V/ZC variants.

Part Context

This part belongs to the Lattice ispMACH 4000Z family, which integrates non-volatile configuration memory. The 'LA' prefix typically denotes automotive-grade devices within the broader ispMACH portfolio, distinguishing them from standard commercial or industrial versions.

Replacement Considerations

Direct pin-compatible replacements include other members of the LA4128V series with identical package footprints. Verify electrical specifications and qualification status before substituting with non-automotive graded parts.
