• Combinatorial PAL device applications

Part Context

This component belongs to the PALCE20V8 family of Electrically Erasable Programmable Logic Devices (EE PLD). It is designed as a high-speed, low-power solution compatible with standard PAL architectures. The 'H' suffix typically denotes specific packaging or temperature variants within the Lattice/Vantis product line, while 'E4/BLA' indicates the specific package type and environmental compliance status.

Replacement Considerations

The PALCE20V8H-25E4/BLA is pin and function compatible with all PAL 20V8 devices. It serves as a direct plug-in replacement for GAL20V8 and PAL20R8 series components. Designers should verify that the target application utilizes standard PAL programming tools compatible with EE PLD structures.
