GAL20RA10B-20LPI

Programmable Logic Device Pld Overview

The GAL20RA10B-20LPI is a high-speed asynchronous E2CMOS programmable logic device (PLD) manufactured by Lattice Semiconductor. It features 10 macrocells and operates within a supply voltage range of 4.5V to 5.5V. The component exhibits a maximum propagation delay of 20ns and supports a maximum operating frequency of 25MHz. It functions reliably across an industrial temperature range from 0°C to +75°C. The device is housed in a 24-pin PDIP package with through-hole mounting, drawing a typical operating supply current of 100mA.

Programmable Logic Device Pld Feature Summary

• Utilizes high-speed asynchronous E2CMOS technology for efficient programmable logic implementation
• Provides flexible configuration through 10 dedicated macrocells for custom logic design
• Supports standard through-hole installation via a 24-pin dual in-line package

Programmable Logic Device Pld Applications

• General-purpose digital logic replacement
• Address decoding circuits
• Simple state machine implementation

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'LPI' to confirm the 20ns speed grade and PDIP package variant. Ensure compatibility with existing 5V logic levels and interface requirements. Confirm that the 10-macrocell capacity meets the design complexity needs. Check for obsolescence status as older PLD families may have limited availability or end-of-life implications.

Programmable Logic Device Pld Selection Notes

Select this component when a simple, cost-effective solution for low-count logic functions is required. It serves as a direct drop-in replacement for legacy GAL devices in designs utilizing 24-pin DIP footprints. Consider its 20ns delay limit for timing-critical paths and ensure the 10-macrocell resource suffices for the intended application without requiring more complex CPLDs.

Programmable Logic Device Pld Part Context

This part belongs to the GAL20RA10B series of Simple Programmable Logic Devices (SPLDs). It represents a standard offering from Lattice Semiconductor's historical portfolio of Generic Array Logic products. These devices were widely used before the dominance of modern FPGAs for basic logic control tasks.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible substitutes include other GAL20RA10B variants with different speed grades, such as the GAL20RA10B-30LP. Cross-vendor equivalents exist but require careful verification of electrical characteristics and pinout definitions.
