GAL16V8D-25LPI

Programmable Logic Device Pld Overview

The GAL16V8D-25LPI is a discontinued high-performance E2CMOS programmable logic device (PLD) from Lattice Semiconductor. It features Electrically Erasable (E2) floating gate technology, allowing for rapid reprogramming with erase times under 100ms and over 20 years of data retention. The device utilizes UltraMOS advanced CMOS technology to achieve significant power reductions compared to bipolar devices. It includes eight output logic macrocells (OLMCs) that support registered, complex, and simple modes, providing flexibility for various logic designs.

Programmable Logic Device Pld Feature Summary

• High Performance E2CMOS Technology: Features a maximum propagation delay of 3.5 ns and an Fmax of 250 MHz.
• Low Power Consumption: Offers a 50% to 75% reduction in power compared to bipolar devices, with typical Icc of 75mA for low power variants.
• Reprogrammable Architecture: Supports up to 100 erase/write cycles with high-speed electrical erasure (<100ms).
• Flexible OLMC Configuration: Eight output logic macrocells configurable as registered, complex, or simple outputs.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control

• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor per Product Change Notification (PCN) #09-10. No new units are manufactured. Verification of availability should focus on existing inventory from authorized distributors or third-party suppliers. Ensure the part number matches the specific speed grade (-25) and package type (Plastic DIP, indicated by 'P').

Programmable Logic Device Pld Selection Notes

Select this device only if legacy compatibility with GAL16V8 architectures is required. The -25 suffix indicates a 25ns max propagation delay. The 'I' suffix denotes Industrial temperature range (-40°C to +85°C). The 'P' suffix specifies a Plastic DIP package. Verify that the design does not require active manufacturing support or long-term supply guarantees.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's Generic Array Logic (GAL) family, combining CMOS performance with electrically erasable memory. This specific model, GAL16V8D-25LPI, belongs to the D-series (Industrial/Commercial options) with Low Power characteristics. It serves as a drop-in replacement for many 20-pin PAL devices while offering reprogrammability.

Programmable Logic Device Pld Replacement Considerations

As the device is discontinued, direct replacements must be sourced from secondary markets or equivalent legacy PLDs. Check for functional compatibility with other GAL16V8 variants or modern SPLD/FPGA alternatives if reprogramming capability is not strictly necessary.
