ISPGAL22V10AB-5LN

Programmable Logic Device Pld Overview

The ISPGAL22V10AB-5LN is an in-system programmable simple programmable logic device (SPLD) from the ispGAL22LV10 family, manufactured by Lattice Semiconductor. It features 10 macrocells and operates with a maximum propagation delay of 5 ns. The device utilizes E2CMOS technology, allowing for electrical erasure and reprogramming without removal from the circuit board. It supports standard 22V10 pinouts and logic compatibility while offering reduced power consumption compared to bipolar equivalents. The component is housed in a 28-pin PLCC package.

Programmable Logic Device Pld Feature Summary

• In-system programmability via ISP interface
• 10 macrocells with active pull-ups on all pins
• 5 ns maximum propagation delay
• Compatible with standard 22V10 fuse maps

Programmable Logic Device Pld Applications

• State machine control
• DMA controller interfaces
• Standard logic speed upgrades

Programmable Logic Device Pld Procurement Notes

Verify RoHS compliance status as older GAL series devices may not meet current environmental standards. Confirm package integrity for 28-PLCC variants. Check for end-of-life notifications or last-time buy dates from Lattice Semiconductor distributors. Ensure programming tools support the specific ispGAL architecture.

Programmable Logic Device Pld Selection Notes

Select this model when in-system programming capability is required for legacy 22V10 designs. Compare against GAL22V10D if non-volatile reprogrammability is needed without ISP infrastructure. Verify voltage requirements; this family typically supports 3.3V or 5V operation depending on the specific suffix. Ensure design tools like ispLEVER Classic are available for configuration.

Programmable Logic Device Pld Part Context

This part belongs to the ispGAL22LV10 family, which succeeded the traditional GAL22V10 series by adding in-system programmability. It maintains functional compatibility with earlier bipolar and UVCMOS 22V10 devices while offering lower power consumption and faster switching speeds. The family bridges the gap between fixed logic gates and complex CPLDs.
