LC5512MV-75F256I

Complex Programmable Logic Devices Overview

The LC5512MV-75F256I is a discontinued Complex Programmable Logic Device (CPLD) belonging to the ispXPLD 5000MX family. It features 512 macrocells, 16 Multi-Function Blocks (MFBs), and 193 I/O pins housed in an FPBGA-256 package. The device operates at a maximum frequency of 275 MHz with a typical propagation delay of 4.5 ns. It supports 3.3V core voltage and includes integrated sysCLOCK PLLs for timing control. Configuration utilizes EEPROM/SRAM technology, enabling instant-on capability and infinite reconfigurability via IEEE 1532.

Complex Programmable Logic Devices Procurement Notes

This specific part number is officially discontinued per Product Change Notification #09-10. Verification of current availability requires checking authorized distributors for remaining stock or legacy inventory. Replacement strategies should focus on active members of the ispXPLD 5000MX family or newer Lattice architectures.

Complex Programmable Logic Devices Selection Notes

Select this component only if the design specifically requires the 5000MX architecture's unique memory flexibility or if existing designs mandate this density. Compare against active alternatives like the LC5512MB variant if 2.5V operation is preferred, or consider the LC5768MX for higher density requirements.

Complex Programmable Logic Devices Part Context

The LC5512MV-75F256I represents the 3.3V core version of the 512-macrocell ispXPLD 5000MX series. It sits between the lower-density LC5256MX and higher-density LC5768MX devices. The 'MV' suffix denotes the 3.3V core voltage, distinguishing it from the 2.5V (MB) and 1.8V (MC) variants within the same logical family.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements are limited due to discontinuation. Consider the LC5512MB-75F256I (2.5V core) if voltage compatibility allows. For new designs, evaluate Lattice CrossLink-N or CertusPro-NX families for modern feature sets.
