Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'B' against official Lattice documentation to confirm it denotes the standard 3.3V variant or a specific revision, as datasheets often group B/C/V/Z families together. Ensure the FTN256 package designation matches the required footprint for PCB design. Confirm RoHS compliance status through the manufacturer's current product status page.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require high pin counts (up to 208) and moderate speed (322 MHz) in a compact BGA form factor. Compare against the LC4512V series if lower power consumption is critical, as the V-series typically offers improved power characteristics while maintaining similar logic density and performance metrics.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000B family, which succeeded earlier CPLD generations. It utilizes CMOS technology and supports both 3.3V and 2.5V core voltages. The family is known for fast path delays and wide input gating capabilities, making it suitable for address decoding and counter applications requiring high performance.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the ispMACH 4000 family such as the LC4512V-10FTN256I or LC4512Z-10FTN256I, provided pin compatibility and electrical specifications align with the system requirements.
