GAL20RA10B-15LP

Programmable Logic Device Pld Overview

The GAL20RA10B-15LP is a high-performance Electrically Erasable CMOS (E2CMOS) Programmable Logic Device (PLD) from Lattice Semiconductor. It utilizes Generic Array Logic architecture with reconfigurable logic cells and active pull-ups on all pins. The device features ten output macrocells, supporting complex logic designs with maximum propagation delays of 15 ns. It offers significant power reduction compared to bipolar devices, with typical supply currents of 90 mA for low-power variants. Key capabilities include register preload, power-on reset, and electronic signature identification.

Programmable Logic Device Pld Feature Summary

• High Performance E2CMOS Technology: Features 15 ns maximum propagation delay and Fmax up to 66 MHz.
• Reconfigurable Logic: Utilizes E2 cell technology allowing high-speed electrical erasure (<100ms) and 20-year data retention.
• Power Efficiency: Provides 50% to 75% power reduction versus bipolar equivalents, with typical Icc of 90 mA.
• Functional Compatibility: Fully function/fuse-map/parametric compatible with standard 20-pin PAL devices.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'LP' against official Lattice documentation to confirm it denotes Low Power characteristics rather than a package variant. Ensure the component meets RoHS requirements if applicable, as older E2CMOS PLDs may have varying compliance statuses. Cross-reference the pinout with standard 20-pin DIP or PQCC packages to ensure mechanical compatibility.

Programmable Logic Device Pld Selection Notes

Select this device when replacing legacy bipolar 20-pin PALs requiring higher speed and lower power consumption. The GAL20RA10B series is suitable for designs needing reprogrammability without UV erasure. Consider the GAL22V10B if additional inputs are required, or the GAL16V8B for simpler logic functions with fewer I/O lines.

Programmable Logic Device Pld Part Context

This component belongs to the GAL20V10 family of E2CMOS PLDs. It serves as a drop-in replacement for older bipolar PAL devices in industrial and consumer electronics. The family is characterized by its ability to be electrically erased and reprogrammed multiple times, offering flexibility during prototyping and production adjustments.

Programmable Logic Device Pld Replacement Considerations

Direct functional replacements include other GAL20RA10B variants with different speed grades (e.g., GAL20RA10B-10LP). Verify that the target application does not require the additional input provided by the GAL22V10B series.
