Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B series, designed as a high-performance, low-voltage CPLD. It maintains pin compatibility with other MAX 7000 variants while offering improved speed and lower power consumption due to its 2.5 V operation. The B suffix indicates the specific voltage and performance tier within the broader MAX 7000 product line.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the MAX 7000 family include the EPM7256BQC208-7 and EPM7256BFC256-5N, though package differences (PQFP vs. FBGA) must be accounted for. Verify that the target system supports 2.5 V logic levels if replacing with 3.3 V or 5 V variants.
