GAL16LV8C-10LJN

Programmable Logic Device Pld Overview

The GAL16LV8C-10LJN is a discontinued Generic Array Logic (GAL) programmable logic device manufactured by Lattice Semiconductor. It utilizes low voltage E2CMOS technology and operates at a supply voltage of +3.0V to +3.6V. The device features an 8-output architecture with reprogrammable macrocells, supporting registered, complex, and simple modes. Key electrical specifications include a maximum propagation delay of 15 ns for the -10 speed grade, a maximum clock frequency of 100 MHz, and JEDEC-compatible 3.3V interface standards with 5V tolerant inputs. It is housed in a 20-pin PLCC package.

Programmable Logic Device Pld Procurement Notes

All devices in the GAL16LV8 datasheet have been officially discontinued per Product Change Notifications (PCNs). The GAL16LV8C-10LJN is no longer in production. Verification of availability requires checking secondary market distributors or contacting authorized partners for potential remaining inventory or obsolescence management options.

Programmable Logic Device Pld Selection Notes

When selecting this component, note that it is part of a discontinued product line. Designers should verify if the specific -10 speed grade (15 ns max tpd) meets timing requirements compared to faster variants like the -7 or -3 grades. Ensure the design accommodates the 3.3V core voltage while leveraging the 5V tolerant input buffers for compatibility with existing 5V logic levels.

Programmable Logic Device Pld Part Context

The GAL16LV8 series represents Lattice's low-power evolution of the classic 16V8 GAL architecture. The 'C' suffix denotes the variant with 5V tolerant inputs suitable for mixed-voltage systems, while 'D' variants feature active pull-ups on all pins. The 'JN' suffix indicates a lead-free PLCC package option.

Programmable Logic Device Pld Replacement Considerations

As the device is discontinued, direct replacements are not listed in the official documentation. Engineers may need to evaluate modern Lattice MachXO3 or iCE40 FPGA families for equivalent functionality, considering differences in architecture, programming tools, and pinouts.
