LC4512B-5FT256C

Complex Programmable Logic Devices Overview

The LC4512B-5FT256C is a complex programmable logic device (CPLD) from the Lattice ispMACH 4000B family. It features 32 macrocells, 512 usable macrocells, and supports up to 208 I/O pins. The device operates within a supply voltage range of 2.3V to 2.7V and offers a maximum propagation delay of 5ns. It is housed in a 256-ball fine-pitch ball grid array (FPBGA) package measuring 17x17mm. The component supports in-system programming and functions across an industrial temperature range of 0°C to 90°C.

Complex Programmable Logic Devices Feature Summary

• Supports in-system programming for flexible configuration updates without removal from the circuit board.
• Utilizes non-volatile EEPROM technology to retain programmed logic states when power is removed.
• Integrates high-density interconnect architecture to manage extensive I/O counts within a compact footprint.

Complex Programmable Logic Devices Applications

• High-speed interface bridging between disparate system components
• Address decoding and bus control logic in embedded systems
• State machine implementation for industrial automation controllers

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'FT' against official manufacturer documentation to confirm pinout compatibility and package dimensions, as variations exist within the 4000B series. Confirm RoHS compliance status directly with the supplier, as older production runs may differ from current manufacturing standards. Ensure ESD handling protocols are strictly followed during installation due to the sensitivity of CMOS structures.

Complex Programmable Logic Devices Selection Notes

Select this component when design requirements demand moderate logic density with low power consumption and non-volatile storage capabilities. The 5ns speed grade suits applications requiring fast combinatorial logic response without the complexity of FPGA architectures. Consider the 256-pin package availability relative to board space constraints and routing density requirements compared to smaller QFP alternatives.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000B family, designed to replace legacy GAL and PAL devices while offering higher performance and reprogrammability. The family emphasizes low power operation and ease of use for designers migrating from simple programmable logic devices to more complex solutions.

Complex Programmable Logic Devices Replacement Considerations

Check for LC4512B variants with different speed grades or package types if the FT256 is unavailable. Verify functional equivalence with LC4512V or LC4512Z series parts, noting potential differences in voltage ranges and feature sets before substitution.
