LC4384C-75FN256C

Complex Programmable Logic Devices Overview

The LC4384C-75FN256C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000C family. It features 384 macrocells organized into 24 Logic Array Blocks (LABs). The device provides 48 I/O pins and utilizes an EEPROM non-volatile memory configuration scheme. It operates within a supply voltage range of 1.65 V to 1.95 V, with a typical operating voltage of 1.8 V. The maximum propagation delay is specified at 7.5 ns, supporting system frequencies up to approximately 133 MHz. The component is housed in a 256-pin FineLine BGA package.

Complex Programmable Logic Devices Feature Summary

• 384 Macrocells across 24 LABs for high-density logic implementation
• EEPROM-based non-volatile configuration technology
• System-in-Programmable (SiP) capability for on-system reconfiguration
• Supports 1.8V core voltage with 5V tolerant I/O options

Complex Programmable Logic Devices Applications

• High-speed interface bridging between legacy and modern protocols
• Complex glue logic replacement in industrial control systems
• Address decoding and bus arbitration in embedded computing
• State machine implementation for automated test equipment

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors due to availability constraints. Confirm RoHS compliance status as older manufacturing lots may differ. Check for moisture sensitivity level (MSL) handling requirements prior to soldering. Ensure design files match the specific speed grade suffix (-75) to guarantee timing closure.

Complex Programmable Logic Devices Selection Notes

Select this model when 384 macrocells are required with a 256-ball BGA footprint. Compare against the -5 speed grade if higher frequency performance above 133 MHz is necessary. Consider the LC4384V series if 3.3V operation is preferred over the 1.8V core voltage architecture. Verify pin compatibility if migrating from previous generation CPLDs.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C family, designed for low-power, high-performance applications. It succeeds earlier ispMACH 4000 variants with improved density and lower power consumption. The FPBGA-256 package allows for compact board layouts while maintaining robust thermal performance for continuous operation.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements include other speed grades within the LC4384C series, such as LC4384C-5FN256C or LC4384C-10FN256C, provided timing requirements allow. Cross-family migration to ispMACH 4000V requires voltage level verification.
