GAL16V8D-25LJI

Programmable Logic Device Pld Overview

The GAL16V8D-25LJI is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology and features 16 inputs, 8 outputs, and 8 macrocells within a 20-pin PLCC package. The device operates at a maximum propagation delay of 25 ns with a typical supply current of 75 mA. It supports Industrial temperature ranges (-40°C to +85°C) and includes an electronic signature for identification.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology enabling reprogrammability and high-speed performance.
• Flexible Architecture: Configurable Output Logic Macrocells (OLMCs) supporting Registered, Complex, and Simple modes.
• Electronic Signature: 64-bit reprogrammable memory for user-defined data such as revision numbers or IDs.
• Latch-Up Protection: On-board charge pump and n-channel pull-ups minimize latch-up risks.

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. Verification of availability requires checking secondary market distributors or authorized liquidators like Rochester Electronics. Ensure the specific ordering suffix matches the required industrial grade and lead-free packaging specifications.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with PAL fuse maps is required. Verify that the 25 ns speed grade meets system timing constraints. Consider modern FPGA alternatives for new designs due to the device's obsolete status and limited I/O density compared to contemporary programmable logic solutions.

Programmable Logic Device Pld Part Context

The GAL16V8D series represents Lattice's Generic Array Logic line based on E2CMOS technology. The 'D' suffix denotes the low-power variant, while 'I' indicates Industrial temperature rating. The 'J' suffix specifies the 20-pin Plastic Leadless Chip Carrier (PLCC) package. This family was designed to emulate standard bipolar PAL devices with full parametric compatibility.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-to-pin replacements from other manufacturers are not explicitly listed. Designers should evaluate modern Lattice MachXO or CrossLink FPGA families for functional equivalents.
