GAL16V8D-10LP

Programmable Logic Device Pld Overview

The GAL16V8D-10LP is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes high-performance E2CMOS technology to provide Electrically Erasable and Programmable (E2) floating gate functionality within a 20-pin Plastic DIP package. The device features an architecture of 16 inputs and 8 outputs, with eight Output Logic Macrocells (OLMCs). Key electrical specifications include a maximum propagation delay of 10 ns, a typical operating supply current of 75 mA at Vcc = 5V, and a maximum clock frequency of 100 MHz with external feedback.

Programmable Logic Device Pld Feature Summary

• High Performance E2CMOS Technology: Features UltraMOS advanced CMOS process with a maximum propagation delay of 3.5 ns for the fastest variant; the -10 speed grade offers 10 ns tpd.
• Reprogrammable Architecture: Utilizes E2 cell technology allowing over 100 erase/write cycles and data retention exceeding 20 years without requiring UV erasure.
• Flexible OLMC Configuration: Supports Registered, Complex, and Simple modes, enabling emulation of standard PAL architectures such as 16R8, 16L8, and 10L8.
• Active Pull-Ups: All pins feature active pull-ups to minimize leakage current and improve noise immunity.

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued per Product Change Notification (PCN) #13-10. No new units are manufactured or stocked by Lattice Semiconductor. Verification of availability requires checking third-party distributors for existing inventory or obsolete stock. Designers must account for end-of-life status when integrating this part into new hardware.

Programmable Logic Device Pld Selection Notes

Select the GAL16V8D-10LP only if legacy compatibility with specific PAL fuse maps or parametric characteristics is required. The 'L' suffix indicates Low Power consumption (75 mA typical Icc), while 'Q' denotes Quarter Power. Ensure the design tool supports the G16V8MS or P16V8R device types for proper compilation of registered or combinatorial logic configurations.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's Generic Array Logic line, bridging the gap between fixed-function logic and complex FPGAs. The D-series variants utilize E2CMOS technology, distinguishing them from earlier OTP devices. This specific part number belongs to the commercial grade low-power subset, designed for cost-sensitive applications requiring reprogrammability in a standard 20-pin footprint.

Programmable Logic Device Pld Replacement Considerations

No direct functional replacements are listed in the official datasheet due to the discontinuation of the entire GAL16V8 family. Modern alternatives typically involve Lattice's MachXO or iCE40 FPGA families, though these require architectural redesign and different programming tools.
