LC4032ZC-75TN48C

Overview

The LC4032ZC-75TN48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000 Z series by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/Os within a 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 2.5 ns. Designed for automotive applications, it complies with AEC-Q100 standards and supports a junction temperature range of -40°C to +130°C. The core voltage is 1.8V, while I/Os are 5V tolerant, supporting LVCMOS 3.3/2.5/1.8 and LVTTTL standards.

Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification and support for -40°C to +130°C junction temperatures.
• High-performance logic with a maximum operating frequency of 400 MHz and 2.5 ns propagation delay.
• Low-power architecture utilizing a 1.8V core voltage combined with 5V-tolerant I/Os.
• Compact 48-pin Thin Quad Flat Package (TQFP) suitable for space-constrained designs.

Applications

• Automotive electronic control units requiring high reliability and wide temperature operation.
• Interface bridging between 5V legacy systems and 1.8V or 3.3V modern logic.
• General-purpose digital logic replacement in industrial and consumer electronics.

Part Context

This component is part of the ispMACH 4000 Z family, which integrates the architecture of ispLSI 2000 and ispMACH 4A devices. The 'Z' suffix specifically denotes the automotive-grade variant, offering enhanced thermal performance compared to standard commercial versions like the V, B, or C series.

Replacement Considerations

For non-automotive applications, the LC4032VC-75TN48C or LC4032BC-75TN48C may serve as functional substitutes if extended temperature ranges are not required. Pin compatibility is maintained across the 4032V/B/C/Z series in the TN48 package.
