GAL16V8D-7LJ

Programmable Logic Device Pld Overview

The GAL16V8D-7LJ is a discontinued high-performance Electrically Erasable CMOS (E2CMOS) Programmable Logic Device (PLD) manufactured by Lattice Semiconductor. It utilizes Generic Array Logic architecture with eight Output Logic Macrocells (OLMCs). The device supports registered, complex, and simple logic modes, emulating standard PAL architectures. Key electrical specifications include a maximum propagation delay of 3.5 ns, a maximum operating frequency of 250 MHz, and an active pull-up on all pins. It features E2 cell technology allowing for reprogrammability with over 100 erase/write cycles and 20-year data retention.

Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 datasheet are officially discontinued per Product Change Notifications (PCNs), including PCN#13-10 which applies to the GAL16V8D-7LJ. No new production is available from Lattice Semiconductor. Verification of current availability requires checking third-party distributors or authorized liquidation partners like Rochester Electronics for existing inventory.

Programmable Logic Device Pld Selection Notes

The GAL16V8D-7LJ offers a 3.5 ns speed grade in a PLCC package. Selection should consider that pins 1 and 11 are permanently configured as Clock and Output Enable in registered mode, while they serve as dedicated inputs in complex mode. Designers must account for the device's discontinuation status when planning long-term production lifecycles.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's high-speed PLD line utilizing E2CMOS technology. The 'D' suffix indicates the specific device variant within the GAL16V8 family. The '-7' denotes the 3.5 ns speed grade, and 'LJ' specifies the Plastic Leadless Chip Carrier (PLCC) package type without lead-free certification in the original ordering nomenclature.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the discontinued status, designers typically migrate to modern FPGA families such as the Lattice iCE40 or MachXO series for equivalent functionality with updated manufacturing support.
