GAL16V8ZD-12QS

Programmable Logic Device Pld Overview

The GAL16V8ZD-12QS is a Generic Array Logic (GAL) device from Lattice Semiconductor, utilizing high-performance E²CMOS technology. It features eight output logic macrocells and supports reprogrammable cells with electrical erasure times under 100ms. The device offers a maximum propagation delay of 3.5ns and a maximum operating frequency of 250MHz. Power consumption is significantly reduced compared to bipolar devices, with typical supply currents of 75mA in low-power mode and 45mA in quarter-power mode. It includes active pull-ups on all pins and provides full functional and parametric compatibility with 20-pin PAL devices.

Programmable Logic Device Pld Procurement Notes

Lattice Semiconductor has issued Product Change Notifications indicating that the GAL16V8 product line is discontinued. Designers should consult official PCNs for current status and contact authorized distributors such as Rochester Electronics or Arrow Electronics for availability inquiries regarding legacy stock.

Programmable Logic Device Pld Selection Notes

Select this component for designs requiring replacement of standard PAL logic with reprogrammable flexibility. Verify that the 20-pin package type matches the target footprint. Ensure system requirements align with the specified voltage levels and power modes, noting that specific suffixes may denote temperature grades or package variations.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's entry into electrically erasable programmable logic devices, bridging the gap between fixed-function PALs and more complex FPGAs. This specific part belongs to the mature device category, where newer process technologies have superseded older generations, though support remains available through designated channels.

Programmable Logic Device Pld Replacement Considerations

Due to discontinuation, direct replacements are limited. Evaluate modern Lattice MachXO or CrossLink families for new designs. For pin-compatible swaps, verify electrical characteristics against original specifications, as no identical current-production equivalent exists within the same form factor.
