Lifecycle

Status The ispMACH 4000V family is mature. Availability can vary by speed grade and package. Check current status before new designs

Pin-to-pin options Within the same family, variants may exist with different speed grades or temperature grades. Examples commonly seen in the market include LC4128V family parts with other speed options or package options. Verify exact compatibility against the datasheet and your PCB

Functional alternatives Not pin-compatible. Evaluate as design replacements

- Lattice MachXO and MachXO2 families (for example LCMXO2-1200 series) for non-volatile, low-power CPLD-like use cases

- Xilinx CoolRunner-II XC2C128 series for 128-macrocell CPLD needs

- Microchip ATF1508AS/ATF1508 series for 128-macrocell CPLD functionality

- Intel (Altera) MAX 7000 EPM7128 series for legacy CPLD designs
