LC4512C-35F256C

Complex Programmable Logic Devices Overview

The LC4512C-35F256C is a Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's MachXO family. It features 512 macrocells and operates at a maximum system clock frequency of 350 MHz in the -35 speed grade. The device utilizes non-volatile Flash memory technology for instant-on configuration, eliminating the need for external configuration components. It supports high-density I/O with up to 224 user-accessible pins in the 256-pin FineLine BGA package. Key electrical parameters include a core voltage of 1.8V and support for various I/O standards.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture providing instant power-up functionality without external configuration memory.
• High performance with a 350 MHz system clock frequency and low latency.
• Flexible I/O capabilities supporting multiple voltage standards including 1.8V, 2.5V, and 3.3V.
• Advanced security features including bitstream encryption and anti-tamper protection.

Complex Programmable Logic Devices Applications

• System control and management in industrial automation equipment.
• Interface bridging between legacy protocols and modern high-speed interfaces.
• Power supply monitoring and control in telecommunications infrastructure.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix codes on the component marking against official Lattice documentation to confirm temperature range and package variant. Ensure that the design environment supports the MachXO family toolchain for accurate synthesis and implementation. Check for any recent lifecycle status updates directly from the manufacturer to confirm availability and long-term supply commitments.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile configuration and instant-on capability are required to simplify board design by removing external Flash chips. Compare logic density requirements against the 512 macrocell capacity; if higher density is needed, consider the MachXO2 or MachXO3L families. Evaluate I/O count needs as the F256 package offers up to 224 usable pins, suitable for complex interface applications.

Complex Programmable Logic Devices Part Context

This part belongs to the MachXO series, which represents Lattice's first generation of non-volatile CPLDs. The MachXO line was designed to bridge the gap between traditional EPROM-based CPLDs and volatile FPGA technologies, offering the ease of use of CPLDs with the flexibility and lower power consumption of Flash-based FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package may be found in the MachXO2 series, such as the LCMXO2-5000HC models, though these offer significantly higher logic density. Verify compatibility with existing firmware and timing constraints when migrating to newer generations.
