GAL16V8D-15QJN

Programmable Logic Device Pld Overview

The GAL16V8D-15QJN is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features an architecture with 16 inputs and 8 outputs housed in a 20-pin PLCC package. The device operates at a maximum propagation delay of 15 ns and supports a maximum clock frequency of 45.5 MHz. It draws a typical supply current of 45 mA under quarter-power conditions. Key functional capabilities include reprogrammable logic cells, active pull-ups on all pins, and support for registered, complex, and simple output macrocell configurations.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology enabling high-speed electrical erasure in less than 100ms and data retention exceeding 20 years.
• Flexible Output Logic Macrocells (OLMC): Supports Registered, Complex, and Simple modes to emulate various PAL architectures with full parametric compatibility.
• Low Power Consumption: Offers a 50% to 75% reduction in power compared to bipolar devices, with a typical operating current of 45 mA for the Quarter Power variant.
• Reprogrammability: Features 100 erase/write cycles and includes an electronic signature for identification purposes.

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 has been officially discontinued by Lattice Semiconductor per Product Change Notification PCN#13-10. No new production units are available from the manufacturer. Verification of availability should be restricted to existing inventory held by third-party distributors or surplus suppliers. Designers must account for the end-of-life status when planning long-term manufacturing runs.

Programmable Logic Device Pld Selection Notes

Select this device only if legacy compatibility with specific PAL fuse maps is required. The -15 speed grade provides a 15 ns maximum propagation delay. Ensure the design utilizes the 20-pin PLCC form factor. Consider that the device is electrically erasable, allowing for field reprogramming, which differs from one-time programmable alternatives.

Programmable Logic Device Pld Part Context

The GAL16V8D series belongs to the Generic Array Logic family, designed to replace discrete bipolar logic gates. The 'D' suffix denotes the CMOS version, while 'QJN' specifies the Quarter Power consumption level, PLCC package type, and lead-free construction. This part serves as a direct pin-compatible replacement for older PAL devices in embedded control applications.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Due to the discontinuation of the entire GAL16V8 product line, designers typically migrate to modern CPLD families such as the Lattice MACH XO or ICE40 series, though these require schematic and layout modifications.
