LC4032ZC-5T48C

Overview

The LC4032ZC-5T48C is a complex programmable logic device (CPLD) belonging to the ispMACH 4000V/Z family, manufactured by Lattice Semiconductor. This automotive-grade component integrates 32 macrocells and supports up to 32 I/O pins within a 48-pin TQFP package. It operates at a maximum frequency of 400 MHz with a typical propagation delay of 2.5 ns. The device features a 1.8 V core voltage for low dynamic power consumption while maintaining 5 V compatible I/Os supporting LVCMOS 3.3, LVCMOS 2.5, LVCMOS 1.8, LVTTTL, and PCI interfaces.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for high reliability.
• Superfast performance with a maximum operating frequency of 400 MHz and 2.5 ns propagation delay.
• Low-power architecture utilizing a 1.8 V core voltage combined with 5 V tolerant I/O capabilities.
• In-system programmability via JTAG interface for flexible design updates.

Applications

• Automotive electronic systems requiring AEC-Q100 certified components.
• Industrial control applications needing robust CPLD functionality.
• Consumer electronics utilizing low-power logic control.
• Communication equipment requiring high-speed signal processing.

Procurement Notes

Verify the specific suffix 'Z' confirms automotive grade qualification (AEC-Q100) rather than standard commercial grade. Confirm the temperature range matches application requirements, typically -40°C to +100°C or +125°C junction temperature for automotive variants. Ensure ESD handling protocols are followed during procurement and storage due to moisture sensitivity levels specified in datasheets.

Selection Notes

Select this model when automotive reliability is mandatory alongside high-speed logic operations. The 32 macrocell count suits moderate complexity designs. Compare against the LC4032V series if automotive certification is not required, as the 'Z' suffix denotes specific environmental hardening. Verify pin compatibility with existing TQFP-48 footprints if migrating from other CPLD families.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which merges architectures from ispLSI 2000 and ispMACH 4A devices. The 'Z' designation specifically identifies the automotive-qualified version of the ispMACH 4000V series, offering enhanced thermal and electrical stability compared to standard commercial parts.

Replacement Considerations

Direct replacements include other members of the ispMACH 4000V/Z family such as LC4064ZC-5T48C for higher density. Commercial equivalents like LC4032VC-5T48C lack automotive certification. Cross-family migration to MachXO2 or iCE40 requires significant architectural redesign due to differences between CPLD and FPGA technologies.
