LC4032ZC-35TN48C

Overview

The LC4032ZC-35TN48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V/Z family, manufactured by Lattice Semiconductor. It integrates 32 macrocells and supports up to 32 I/O pins within a 48-pin TQFP package. The device operates with a 1.8 V core voltage for low dynamic power consumption while providing 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. Key electrical specifications include a maximum operating frequency of 400 MHz, a typical standby current of 11.3 µA, and a propagation delay of 2.5 ns.

Feature Summary

• High-performance architecture supporting SuperFAST frequencies up to 400 MHz with 2.5 ns propagation delay.
• Low-power design featuring a 1.8 V core voltage and typical standby current of 11.3 µA.
• 5 V tolerant I/Os supporting LVCMOS 3.3, LVTTL, and PCI interface standards.
• JTAG In-System Programmability (ISP) for flexible configuration.

Applications

• General-purpose logic replacement in industrial control systems.
• Interface bridging between 5 V and 1.8 V logic domains.
• Address decoding and state machine implementation in embedded systems.

Procurement Notes

Verify the specific suffix 'Z' indicates automotive-grade qualification requirements when sourcing. Confirm the package type matches the required 48-pin TQFP form factor. Ensure the temperature grade aligns with the application environment, as the 'C' suffix typically denotes commercial range. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component for designs requiring high-speed logic (400 MHz) with low static power consumption. The 32 macrocell density is suitable for moderate complexity logic functions. Consider the 5 V tolerant I/O capability if interfacing with legacy 5 V peripherals without level shifters. Compare against the standard V-series if automotive qualification is not required.

Part Context

This device is part of the ispMACH 4000V/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The Z-series specifically targets automotive applications, offering extended junction temperature support up to +130 °C compared to standard commercial variants.

Replacement Considerations

The LC4032V-75TN48C is a comparable non-automotive variant within the same family. Verify that the reduced temperature range of the V-series meets the system requirements before substitution.
