LC4512V-5TN176C

Complex Programmable Logic Devices Overview

The LC4512V-5TN176C is a Complex Programmable Logic Device (CPLD) belonging to the Lattice ispMACH 4000V family. It features a logic density of 512 macrocells and supports up to 128 I/O pins within a 176-pin TQFP package. The device operates with a core supply voltage range of 3.0 V to 3.6 V and achieves a maximum propagation delay of 5 ns. It supports In-System Programming via JTAG and includes 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature grade (0°C to 90°C TJ). Confirm package dimensions match the 176-TQFP (24x24 mm) specification. Ensure design tools support the ispMACH 4000V family for programming and simulation.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are required with high pin count. Compare against LC4384V if lower density suffices. Verify voltage compatibility as the core requires 3.3 V while I/Os tolerate 5 V levels.

Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000V series, which blends ispLSI 2000 and ispMACH 4A architectures. It offers density migration capabilities within the family, allowing designers to upgrade from lower-density devices like the LC4256V without changing the board layout significantly.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents within the same package include other speed grades of the LC4512V series. For density reduction, the LC4384V is a compatible alternative.
