Complex Programmable Logic Devices Procurement Notes

Verify the specific package type associated with the 'YI' suffix against official Lattice Semiconductor documentation or authorized distributor datasheets before procurement. Confirm that the required speed grade (-10) meets the timing constraints of the target design. Ensure compatibility with existing design tools for the ispMACH 4A family.

Complex Programmable Logic Devices Selection Notes

Select this device when a design requires 128 macrocells with guaranteed fixed timing characteristics. The -10 speed grade is suitable for applications needing a 10 ns maximum propagation delay. Consider the 3.3 V operation and 5 V input tolerance if interfacing with legacy 5 V logic systems. Verify that the available I/O options match the board layout requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family from Lattice Semiconductor. The family offers densities ranging from 32 to 512 macrocells. The M4A3-128 variant provides a balance of logic density and I/O flexibility, utilizing E2CMOS technology for non-volatile configuration and low static power consumption compared to older EEPROM-based CPLDs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-128 variants with different speed grades (e.g., -5, -55, -6, -65, -7, -12) or package options. Cross-family migration to newer Lattice CPLD families may require architectural redesign due to differences in macrocell structure and routing resources.
