LC5768VG-10F256C

Complex Programmable Logic Devices Overview

The LC5768VG-10F256C is a Complex Programmable Logic Device (CPLD) from the Lattice ispXPLD family, manufactured by Lattice Semiconductor Corporation. It features 768 macrocells and 176 I/Os housed in a 256-ball FPBGA package. The device operates at a maximum frequency of 100 MHz with a typical propagation delay of 10 ns. It utilizes EEPROM/SRAM storage technology and functions within a supply voltage range of 2.3 V to 2.7 V, consuming approximately 40 mA of current. The component supports an operating temperature range from 0°C to +90°C.

Complex Programmable Logic Devices Feature Summary

• High-density logic architecture with 768 macrocells and 24 Logic Array Blocks (LABs).
• Fast performance with a maximum operating frequency of 100 MHz and 10 ns propagation delay.
• EEPROM/SRAM non-volatile configuration storage for instant-on capability.
• 176 available I/O pins supporting diverse interface requirements.

Complex Programmable Logic Devices Applications

• High-speed data acquisition systems requiring deterministic logic control.
• Interface bridging between legacy protocols and modern high-speed buses.
• Complex glue logic replacement in industrial automation controllers.
• Signal processing front-ends in telecommunications infrastructure.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'VG' against official Lattice documentation to confirm voltage grade and temperature range specifications. Confirm RoHS compliance status as historical CPLD data may vary by production batch. Check for End-of-Life (EOL) notifications or last-time-buy dates through authorized distributors. Ensure moisture sensitivity level (MSL) handling procedures are followed during assembly due to the BGA package type.

Complex Programmable Logic Devices Selection Notes

Select this model when a high pin count (176 I/Os) and moderate logic density (768 macrocells) are required. The 10 ns speed grade suits applications needing faster switching than standard 15 ns variants but lower power than higher-speed FPGA alternatives. Compare against the LC57256 series if fewer I/Os are acceptable for cost reduction. Verify that the 2.5V core voltage aligns with system power rails.

Complex Programmable Logic Devices Part Context

This part belongs to the ispXPLD family, designed for high-performance, high-density programmable logic applications. It bridges the gap between simple PLDs and complex FPGAs, offering non-volatile configuration without external boot flash memory. The FPBGA-256 package provides a compact form factor suitable for space-constrained PCB designs requiring robust signal integrity.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be verified via Lattice's cross-reference tools. Consider the LC5768VG-10F256I for industrial temperature ranges if applicable. Evaluate newer Lattice Nexus or MachXO families for improved power efficiency and security features, noting potential architectural differences.
