GAL16V8D-15QP

Programmable Logic Device Pld Overview

The GAL16V8D-15QP is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes high-performance E2CMOS technology to achieve a maximum propagation delay of 15 ns and a maximum operating frequency of 125 MHz with no feedback. The device features eight output logic macrocells, 16 inputs, and an 8-bit electronic signature for identification. It operates within a supply voltage range of 4.75 V to 5.25 V and is housed in a 20-pin Plastic Leadless Chip Carrier (PLCC) package.

Programmable Logic Device Pld Feature Summary

• High Performance E2CMOS Technology: Supports up to 250 MHz operation with 3.5 ns minimum propagation delay across the family.
• Reprogrammable Architecture: Features Electrically Erasable floating gate technology allowing over 100 erase/write cycles and 20-year data retention.
• Flexible Output Logic Macrocells (OLMC): Configurable as simple, complex, or registered modes to emulate various PAL architectures.
• Electronic Signature: Includes 64 bits of reprogrammable memory for user-defined identification data.

Programmable Logic Device Pld Applications

• DMA Control

Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 datasheet have been officially discontinued via Product Change Notification (PCN). The GAL16V8D-15QP is not available for new production orders from Lattice Semiconductor. Verification of current availability requires contacting authorized distributors or secondary market suppliers, as inventory is limited or exhausted.

Programmable Logic Device Pld Selection Notes

Designers should note that the GAL16V8D-15QP is obsolete. Selection of this component is restricted to maintenance of existing legacy systems. For new designs, replacement with modern SPLDs or FPGAs is required. Verify that the 20-pin PLCC package footprint matches the target PCB layout if sourcing from surplus stock.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents a generic array logic device combining CMOS speed with electrically erasable non-volatile memory. The 'Q' suffix denotes the Plastic Leadless Chip Carrier package, while '15' indicates the 15 ns speed grade. This specific part number falls under the commercial grade specifications defined in the September 2010 datasheet revision.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Due to the discontinuation status, designers must evaluate modern low-power FPGAs or CPLDs from Lattice or other vendors that offer equivalent pin counts and logic capacity.
