ISPGAL22LV10-5LK

Programmable Logic Device Pld Overview

The ISPGAL22LV10-5LK is a high-performance, electrically erasable programmable logic device (E2CMOS) from Lattice Semiconductor. It features a maximum propagation delay of 4ns and operates at frequencies up to 250 MHz. The device utilizes UltraMOS advanced CMOS technology for low power consumption, offering a 50% to 75% reduction compared to bipolar equivalents. It includes ten output logic macrocells with active pull-ups on all pins, ensuring compatibility with standard 22V10 devices while providing reconfigurable logic capabilities.

Programmable Logic Device Pld Feature Summary

• High Performance E2CMOS Technology: 4ns max propagation delay and 250 MHz Fmax
• Low Power Consumption: 50-75% reduction vs. bipolar devices; typical Icc of 90mA (low power) or 45mA (quarter power)
• Reprogrammable Cells: Fast electrical erase times (<100ms) and 20-year data retention
• Full Compatibility: Functionally and parametrically compatible with bipolar and UVCMOS 22V10 devices

Programmable Logic Device Pld Applications

• DMA Control systems
• State Machine Control
• High Speed Graphics Processing
• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix '5LK' against official Lattice documentation to confirm package type and temperature range. Ensure design requirements align with the 22V10 pinout and electrical specifications. Confirm that the E2CMOS technology meets the necessary reprogramming endurance and data retention standards for the target application environment.

Programmable Logic Device Pld Selection Notes

Select this component when upgrading from bipolar GAL22V10 devices to reduce power consumption without changing the board layout. It is suitable for applications requiring fast logic switching (up to 250 MHz) and in-system reconfigurability. Consider the 10 macrocell count for complex logic designs needing active pull-ups on all outputs.

Programmable Logic Device Pld Part Context

The ISPGAL22LV10 series belongs to Lattice's GAL family of Electrically Erasable Programmable Logic Devices. These devices are designed as drop-in replacements for older bipolar GAL22V10 parts, offering improved performance and lower power. The 'ISP' designation indicates In-System Programmability via the TAP controller, allowing for field updates and debugging.

Programmable Logic Device Pld Replacement Considerations

For new designs, Lattice recommends evaluating the ispMACH 4000V series as a modern alternative. The GAL22LV10 is classified as a mature product, and while supported, it may be superseded by newer technologies for future development cycles.
