LC5768MB-75F256C

Complex Programmable Logic Devices Overview

The LC5768MB-75F256C is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor. It features a 768 macrocell architecture with 193 I/O lines and operates at a maximum propagation delay of 7.5 ns. The device is housed in a 256-ball Fine-Pitch Ball Grid Array (FPBGA) package, measuring 16x16 mm. It supports In-System Programming (ISP) via JTAG and complies with RoHS standards.

Complex Programmable Logic Devices Feature Summary

• 768 Macrocells with 193 I/Os
• 7.5 ns Maximum Propagation Delay
• In-System Programmable (ISP) via JTAG
• 256-Ball FPBGA Package

Complex Programmable Logic Devices Applications

• General-purpose logic replacement
• Address decoding
• Bus bridging

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-75) against the manufacturer's datasheet to confirm the 7.5 ns timing specification. Ensure the FPBGA-256 package footprint matches the PCB design requirements. Confirm moisture sensitivity level (MSL 3) handling procedures during assembly.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring moderate I/O density (193 pins) with low power consumption typical of EE PLDs. The 7.5 ns speed is suitable for mid-range control applications. Compare against the -4 variant if slower speeds are acceptable for cost reduction.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice MachXO or similar EE PLD families, designed for low-power, high-density logic applications. It serves as a drop-in replacement for complex discrete logic gates, reducing board space and power usage compared to traditional TTL/CMOS solutions.

Complex Programmable Logic Devices Replacement Considerations

Check for direct pin-compatible alternatives within the same Lattice family, such as the LC5768MB-4F256C, noting the difference in propagation delay (9.5 ns vs 7.5 ns). Verify that any substitute maintains the 256-pin BGA footprint and ISP capabilities.
