LC51024VG-5F484C

Complex Programmable Logic Devices Overview

The LC51024VG-5F484C is a complex programmable logic device (CPLD) from Lattice Semiconductor's MachXO2 family. It features 10,240 system-on-programmable-logic macrocells and supports up to 360 user I/Os. The device operates with a core voltage range of 1.14V to 1.26V and is housed in a 484-ball fine-pitch ball grid array (FPBGA) package measuring 23x23 mm. It includes embedded Flash memory for non-volatile configuration and supports in-system programming via JTAG or SPI interfaces.

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 10,240 macrocells and 360 I/Os
• Embedded Flash technology enabling instant-on operation without external configuration memory
• Supports high-speed serial interfaces including PCIe Gen1 x1/x2/x4 and Gigabit Ethernet
• Integrated PLLs for clock management and phase shifting

Complex Programmable Logic Devices Applications

• PCI Express interface bridging and protocol conversion
• Gigabit Ethernet media access control (MAC) layer implementation
• System control and monitoring in industrial infrastructure
• Boot controller for flash-based systems

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'V' indicates the commercial temperature grade and 'G' denotes lead-free compliance. Confirm the '-5' speed grade matches the required timing constraints for the target design. Ensure the FPBGA-484 package dimensions align with the PCB footprint specifications provided in the official datasheet.

Complex Programmable Logic Devices Selection Notes

Select this component when a high pin count CPLD with embedded Flash is required to replace volatile SRAM-based FPGAs. The MachXO2 family offers lower power consumption compared to traditional SRAM FPGAs while providing sufficient logic density for control applications. Verify that the 360 I/O limit satisfies the interface requirements before considering larger devices in the same family.

Complex Programmable Logic Devices Part Context

This part belongs to the MachXO2 family, which bridges the gap between low-density CPLDs and high-density FPGAs. It combines the ease of use and instant-on capability of Flash-based CPLDs with the performance features typically found in FPGAs, such as dedicated clocking resources and high-speed serial transceivers.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the Lattice portfolio include other MachXO2 devices with higher or lower macrocell counts, such as the LC5128M or LC5256 variants, provided the package and pinout compatibility are maintained.
