Application Scenarios & Design Considerations

In-System Programmable 3.3V SuperWIDE? High Density PLD

Alternative Part Number

  • LC5256MV-125F256C --: Same ispMACH 5000 family CPLD with equivalent 256-macrocell density and 125 ns speed grade, offered in a different package and naming series, making it a close functional replacement.
  • M4A5-256/128-10YNC --: Lattice MACH4A5 CPLD with 256 macrocells and comparable logic capacity; different series name and package, suitable as a cross-family alternative when the LB272 BGA footprint is not mandatory.
  • EPM3256AQC208-10N --: Altera MAX 3000A CPLD with 256 macrocells and similar 3.3V operation; a well-known second-source style alternative with clearly different naming and package, usable after pinout and timing verification.
