LC5768VG-12F256I

Complex Programmable Logic Devices Overview

The LC5768VG-12F256I is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor. It features a density of 768 macro cells and supports up to 193 I/O pins within a 256-pin FineLine BGA package. The device operates with a maximum propagation delay of 12 ns, enabling high-speed logic implementation. Key specifications include in-system programmability via JTAG and compliance with RoHS standards for lead-free manufacturing.

Complex Programmable Logic Devices Feature Summary

• 768 Macro Cells: Provides substantial logic capacity for complex digital designs.
• In-System Programmability: Supports non-volatile configuration updates without removing the component from the PCB.
• High Pin Count: Offers 193 I/Os in a compact 256-pin FPBGA package.
• JTAG Interface: Enables standard boundary scan testing and programming.

Complex Programmable Logic Devices Applications

• Complex glue logic replacement
• Address/data buffering
• Protocol bridging

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'VG' against the manufacturer's current product selector guide to confirm availability status and exact electrical characteristics. Ensure the design environment supports the required JEDEC voltage levels for the FineLine BGA package. Confirm moisture sensitivity level 3 handling requirements during assembly.

Complex Programmable Logic Devices Selection Notes

Select this model when a high pin count EE PLD with in-system programmability is required. Compare the 12 ns speed grade against the -5 variant if timing constraints allow for lower performance but potentially different availability. Verify that the 256-pin footprint matches the target PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the LatticeLC5000V family of EE PLDs. These devices utilize EEPROM technology for non-volatile storage, allowing them to retain configuration data without power. The family is designed for applications requiring reprogrammability and moderate logic density.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the LC5768 series, such as the LC5768VG-5F256I, provided the timing requirements are met. Cross-family migration requires schematic and layout verification.
