GAL20VP8B-15LP

Programmable Logic Device Pld Overview

The GAL20VP8B-15LP is a high-performance E²CMOS Complex Programmable Logic Device (CPLD) manufactured by Lattice Semiconductor. It features a 24-pin DIP package and operates within an industrial temperature range of -40°C to +85°C. The device provides 8 macrocells with registered outputs, supporting a maximum propagation delay of 15 ns. It utilizes UltraMOS technology for low power consumption and includes active pull-ups on all pins. The component is marked as obsolete in the manufacturer's lifecycle.

Programmable Logic Device Pld Feature Summary

• E²CMOS Technology: Combines EEPROM non-volatility with CMOS performance, offering 100% electrical erasure and reprogrammability.
• Registered Outputs: Features 8 output logic macrocells with programmable output polarity and register preload capabilities.
• Low Power Consumption: Achieves significant power reduction compared to bipolar devices, with typical Icc of 75mA on low-power variants.
• High Reliability: Includes active pull-ups on all pins and supports up to 100 program/erase cycles.

Programmable Logic Device Pld Applications

• Replacement for legacy PAL and PLD devices in existing designs.
• Address decoding and chip select generation in microprocessor systems.
• State machine implementation for control logic.
• Bus protocol conversion and interface bridging.

Programmable Logic Device Pld Procurement Notes

This component is officially designated as obsolete by Lattice Semiconductor. Verification of availability should focus on surplus distributors or secondary markets. Buyers must confirm the specific suffix 'LP' corresponds to the lead-free and RoHS-compliant version if environmental compliance is required. Cross-reference with equivalent GAL20V8B variants is recommended for new designs.

Programmable Logic Device Pld Selection Notes

Select this part when a registered output configuration is required for 8 macrocells in a 24-pin package. The '15' speed grade indicates a 15 ns maximum propagation delay. Ensure the design accommodates the through-hole DIP-24 footprint. Compare against GAL20V8B-15LPNI for pin-compatible alternatives with different packaging or compliance markings.

Programmable Logic Device Pld Part Context

The GAL20VP8B series belongs to Lattice's GAL20V8 family of E²CMOS PLDs. These devices are designed to be functionally and parametrically compatible with standard 20-pin and 24-pin PAL devices while offering reprogrammability. The GAL20VP8B specifically targets applications requiring registered outputs and higher density than the GAL16V8.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include GAL20V8B-15LPNI (RoHS compliant, tube packaging). For modern FPGA-based upgrades, consider Lattice MachXO or iCE40 series devices, though pin compatibility will differ.
