GAL16V8D-15LP

Programmable Logic Device Pld Overview

The GAL16V8D-15LP 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 DIP package. The device specifies a maximum propagation delay of 15 ns and a maximum clock frequency of 45.5 MHz. Operating at 5V, it offers low power consumption with typical supply currents of 75 mA for the Low Power variant. The component includes eight Output Logic Macrocells (OLMCs) supporting registered, complex, and simple modes.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology enabling high-speed reprogramming (<100ms) and 20-year data retention.
• Flexible OLMC Architecture: Eight macrocells configurable as Registered, Complex, or Simple logic functions to emulate various PAL devices.
• Active Pull-ups: All pins feature active pull-up resistors to minimize latch-up potential.
• Electronic Signature: Includes 64 bits of reprogrammable memory for user-defined identification data.

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 part number is officially discontinued per Product Change Notification PCN#13-10. No new units are manufactured by Lattice Semiconductor. Verification of availability requires checking secondary market distributors for existing inventory. Designers should confirm lead times and authenticity carefully when sourcing from non-original suppliers.

Programmable Logic Device Pld Selection Notes

Select this component only for legacy system maintenance where specific pin compatibility and timing characteristics (15 ns delay) are required. Due to discontinuation, alternative SPLDs or FPGAs must be evaluated for new designs. Ensure the selected package matches the PCB footprint, as the 'P' suffix denotes a Plastic DIP package.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's Generic Array Logic line based on E2CMOS technology. The 'D' suffix indicates the second generation of this architecture. This specific model falls under the commercial grade specifications with a -15 speed grade, providing a balance between switching speed and power consumption compared to faster or lower-power variants.

Programmable Logic Device Pld Replacement Considerations

Lattice has not published a direct functional replacement part number for the GAL16V8D-15LP within the same datasheet. Users are advised to consult Lattice Semiconductor for modern FPGA or CPLD equivalents suitable for migrating legacy GAL designs.
