LC4512C-5FT256I

Complex Programmable Logic Devices Overview

The LC4512C-5FT256I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000C family. It features 512 macrocells and supports up to 208 I/O pins within a 256-pin FineLine BGA package. The device operates on a single 1.8V supply voltage with a maximum propagation delay of 5 ns and a maximum operating frequency of 333 MHz. It includes system-in-system programmability, JTAG support, and is rated for industrial temperature ranges (-40°C to +105°C).

Complex Programmable Logic Devices Feature Summary

• High performance: 5 ns max propagation delay and 333 MHz max frequency.
• High density: 512 macrocells and up to 208 user I/Os.
• Industrial grade: Operates reliably from -40°C to +105°C junction temperature.
• Flexible programming: Supports In-System Programming (ISP) and JTAG boundary scan.

Complex Programmable Logic Devices Applications

• High-speed interface bridging in industrial automation systems.
• Complex glue logic replacement in telecommunications equipment.
• Control logic for high-density data acquisition modules.
• Protocol conversion between legacy and modern bus standards.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'FT' indicates the 256-pin FineLine BGA package and 'I' denotes the industrial temperature range. Confirm the '-5' speed grade matches the required 5 ns timing constraints for the target design. Ensure the component status is checked against current manufacturing availability as older CPLD families may have limited stock or end-of-life notices.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require high pin counts (up to 208) and fast switching speeds (5 ns) in a compact BGA footprint. Compare against the LC4512C-5TN176I if a QFP package is preferred but fewer I/Os are acceptable. Consider the LC4512C-5FTN256C if commercial temperature range (0°C to 90°C) suffices, potentially offering different supply chain options.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C family, designed for high-performance applications requiring non-volatile configuration and low power consumption. It serves as a successor to earlier ispMACH 4000 variants, offering improved speed and density while maintaining backward compatibility with existing design tools and methodologies.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements include other variants within the LC4512C family such as LC4512C-5FT256C (commercial temp) or LC4512C-10FT256I (slower speed). Verify that any substitute maintains the same 256-pin FTBGA outline and electrical characteristics.
