GAL16V8ZD-15QP

Programmable Logic Device Pld Overview

The GAL16V8ZD-15QP is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, belonging to the GAL16V8 family. It utilizes E2CMOS technology for electrically erasable programmability with high-speed erase capabilities under 100ms. The device features an architecture of 16 inputs and 8 outputs, housed in a 28-pin Plastic Quad Flatpack (PQCC) package. It operates at a maximum propagation delay of 15ns and supports a maximum clock frequency of 45.5 MHz. The component includes eight output logic macrocells with programmable polarity and register preload functionality.

Programmable Logic Device Pld Procurement Notes

This specific part number is officially discontinued by Lattice Semiconductor. Product Change Notifications (PCN) confirm that all devices in the GAL16V8 series are no longer in production. Verification of availability requires checking authorized distributors or third-party suppliers for existing stock, as direct manufacturing supply has ceased.

Programmable Logic Device Pld Selection Notes

Designers should evaluate advanced replacement families such as the MachXO or CrossLink series for new projects. The GAL16V8ZD-15QP serves primarily as a drop-in replacement for legacy bipolar PAL devices due to its functional and parametric compatibility. Ensure that the 28-pin PQCC footprint matches the target PCB layout if substituting into existing hardware.

Programmable Logic Device Pld Part Context

The GAL16V8ZD-15QP is part of the broader GAL16V8 product line, which was designed to emulate 20-pin PAL devices while offering enhanced flexibility through electrically erasable cells. This specific suffix indicates the 15ns speed grade and the 28-pin PQCC package variant within the discontinued portfolio.

Programmable Logic Device Pld Replacement Considerations

Lattice recommends transitioning to modern FPGA families like MachXO2 or iCE40 for new designs. For pin-compatible replacements, verify electrical parameters against similar SPLDs from other manufacturers, noting that the original device is obsolete.
