GAL22CV10-LNC

Programmable Logic Device Pld Overview

The GAL22CV10-LNC is a Generic Array Logic (GAL) device manufactured by National Semiconductor. It utilizes E2CMOS technology, combining high-speed CMOS performance with Electrically Erasable and Programmable logic capabilities. The component features 22 input pins and 10 output pins, structured around Output Logic Macrocells (OLMCs) that provide design flexibility for complex combinational or registered logic applications. As an electrically erasable PLD, it supports repeated programming cycles, offering a reconfigurable alternative to traditional mask-programmed PAL devices while maintaining compatibility with standard 22V10 pinouts.

Programmable Logic Device Pld Part Context

The GAL22CV10-LNC belongs to the GAL22V10 family of high-performance PLDs. The 'C' suffix typically denotes commercial temperature range operation, while 'LNC' indicates specific packaging and lead-free compliance attributes defined by National Semiconductor. This series bridges the gap between fixed-function logic and complex FPGAs, serving as a cost-effective solution for medium-complexity logic designs requiring field reprogrammability.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other GAL22V10 variants from National Semiconductor or Lattice Semiconductor, such as the GAL22V10B-15LJ. When substituting, verify that the replacement device matches the required speed grade and package type. Ensure the new component supports the same voltage levels and OLMC configurations used in the original design.
