GAL16V8D-10LJN

Programmable Logic Device Pld Overview

The GAL16V8D-10LJN is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 16 inputs and 8 outputs in a 20-pin PLCC package. The device specifies a maximum propagation delay of 10 ns and a maximum operating frequency of 83.3 MHz under no-feedback conditions. Operating at 5V, the quarter-power variant draws a typical supply current of 45 mA with a maximum of 55 mA. It supports Electrically Erasable floating gate technology for reprogramming.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Utilizes electrically erasable floating gate technology allowing high-speed electrical erasure in less than 100ms and data retention exceeding 20 years.
• Reconfigurable Architecture: Features eight Output Logic Macrocells (OLMCs) supporting simple, complex, and registered modes to emulate various PAL architectures.
• Low Power Consumption: Quarter-power version reduces power consumption by up to 75% compared to bipolar devices, with a typical Icc of 45 mA.
• Active Pull-ups: All pins include active pull-up resistors to minimize latch-up potential caused by input undershoots or output overshoots.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• High Speed Graphics Processing
• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#13-10. No new production units are available from Lattice Semiconductor. Verification of availability should be restricted to existing inventory held by third-party distributors or secondary market suppliers. Designers must assess end-of-life status for long-term projects.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with specific PAL fuse maps is required. The -10 speed grade offers a 10 ns maximum propagation delay. Ensure the design utilizes the 20-pin PLCC footprint. Consider that the device requires a 5V supply and verify that compiler software supports the GAL16V8 device type for proper OLMC configuration.

Programmable Logic Device Pld Part Context

The GAL16V8D series belongs to the Generic Array Logic family, designed to provide flexibility through reprogrammable macrocells. The 'D' suffix indicates the low-power CMOS variant. The 'LJN' ordering suffix denotes a Lead-free PLCC package. This device serves as a drop-in replacement for many standard 20-pin PAL devices while offering full function and parametric compatibility.

Programmable Logic Device Pld Replacement Considerations

No direct functional substitutes are listed in the provided documentation. Due to discontinuation, alternative SPLDs or CPLDs from other manufacturers may require schematic and firmware modifications. Verify pinout compatibility if considering cross-vendor replacements.
