PALCE26V12H-20PC/4 – LATTICE SEMI

The PALCE26V12H-20PC/4 is a high-performance, electrically erasable programmable logic device (EE PLD) manufactured by Lattice Semiconductor. Designated as a 26V12 architecture, it features 26 inputs and 12 outputs, configurable via programmable AND and fixed OR logic arrays. The “-20” suffix indicates a maximum propagation delay of 20 nanoseconds from input to output, defining its speed grade. The “PC” denotes that it is packaged in a plastic DIP (Dual In-Line Package), facilitating through-hole mounting on printed circuit boards. The “/4” likely represents a specific revision or lot code, though its precise meaning is proprietary to Lattice. This device is designed for applications requiring combinatorial and sequential logic functions, offering in-system programmability and reprogrammability for design flexibility and prototyping. The 2002 date code suggests it is a mature product, potentially with limited availability.
