LC4032V-5TN48C

Overview

The LC4032V-5TN48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/Os within a TQFP-48 package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 5 ns. It utilizes a 3.3V core supply voltage and includes 5V-tolerant I/Os compatible with LVCMOS 3.3, LVCMOS 2.5, LVCMOS 1.8, and PCI interfaces. The component is designed for surface-mount installation and functions within an operating temperature range of 0°C to +90°C.

Feature Summary

• High-speed performance with a maximum frequency of 400 MHz and 5 ns propagation delay.
• Low-power architecture featuring a 1.8V core voltage and 3.3V supply operation.
• 5V-tolerant I/Os supporting multiple interface standards including LVCMOS and PCI.
• Robust Global Routing Pool and Output Routing Pool for timing predictability.

Applications

• General-purpose logic interfacing in industrial control systems.
• Address decoding and bus buffering in embedded computing platforms.
• Signal translation between different voltage domains.
• Replacement for legacy GAL devices in existing circuit designs.

Procurement Notes

Verify the specific suffix 'TN48' confirms the TQFP-48 package and commercial temperature grade (0°C to +90°C). Ensure the 'V' series designation aligns with the required 3.3V core voltage specifications. Confirm RoHS compliance status through the manufacturer's current documentation before procurement.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The 5 ns speed grade offers a balance between performance and power consumption compared to faster variants. Consider the TQFP-48 package constraints regarding board space and thermal dissipation requirements for the target application environment.

Part Context

This component is part of the ispMACH 4000V family, which integrates the architecture of previous ispLSI 2000 and ispMACH 4A devices. The family emphasizes low power and superfast performance, utilizing non-volatile CMOS technology that allows for in-system programming via JTAG without requiring external configuration memory.

Replacement Considerations

Direct pin-compatible replacements within the same family include the LC4032V-75TN48C, which offers a slower 7.5 ns propagation delay but maintains identical pinout and functionality. Verify that any substitute meets the specific 5 ns timing requirements of the original design.
