GAL16VP8B-15LP

Programmable Logic Device Pld Overview

The GAL16VP8B-15LP is a high-performance E²CMOS Programmable Logic Device (PLD) from Lattice Semiconductor, belonging to the GAL16V8 family. It features an EE PLD architecture with a maximum propagation delay of 9 ns and a maximum clock frequency of 45.5 MHz. The device utilizes UltraMOS technology and includes eight output logic macrocells with programmable output polarity. Key functional features include active pull-ups on all pins, register preload capability, and power-up reset for all registers. It is housed in a 20-pin plastic DIP package.

Programmable Logic Device Pld Feature Summary

• High Performance E²CMOS Technology: Achieves 9 ns maximum propagation delay and 45.5 MHz max clock frequency.
• Eight Output Logic Macrocells: Provides flexibility for complex logic designs with programmable output polarity.
• Active Pull-Ups: Ensures defined states on all pins via active pull-up technology.
• Register Control: Supports preload and power-on reset functions for all internal registers.

Programmable Logic Device Pld Applications

• Replacement for legacy bipolar PAL devices requiring full function/fuse map compatibility.
• Complex logic design implementations utilizing reconfigurable logic cells.
• Systems requiring specific register preload or power-up reset initialization sequences.

Programmable Logic Device Pld Procurement Notes

Lattice Semiconductor has issued Product Change Notifications (PCNs) discontinuing all devices in the GAL16V8 datasheet, including the GAL16VP8B-15LP. Verification of current availability requires checking specific PCN status codes (e.g., PCN#06-07, PCN#13-10). Designers should confirm if the component is listed as discontinued or obsolete before procurement planning.

Programmable Logic Device Pld Selection Notes

Select this component when a direct pin-compatible replacement for standard 20-pin PAL devices is required with lower power consumption. The GAL16VP8B-15LP offers a 75% reduction in power compared to bipolar equivalents. Ensure the design accommodates the 9 ns propagation delay and utilizes the available 18 inputs and 8 outputs within the 20-pin DIP footprint.

Programmable Logic Device Pld Part Context

The GAL16VP8B-15LP is part of the Generic Array Logic (GAL) family manufactured by Lattice Semiconductor. This series was designed to emulate 20-pin PAL devices while offering reprogrammable cells and higher speed electrical erasure capabilities. The 'B' suffix typically denotes specific speed grades or revisions within the GAL16V8 product line.

Programmable Logic Device Pld Replacement Considerations

All GAL16V8 devices have been officially discontinued by Lattice Semiconductor. No direct public substitute part numbers are confirmed in the provided documentation. Designers must evaluate alternative FPGA or CPLD solutions for new designs, as existing inventory may be limited to surplus stock.
