ISPGAL22V10AV-75LN

Programmable Logic Device Pld Overview

The ISPGAL22V10AV-75LN is a Simple Programmable Logic Device (SPLD) from the ispGAL22V10 family, manufactured by Lattice Semiconductor. It features an Electrically Erasable CMOS (E2CMOS) technology architecture, supporting in-system programming capabilities. The device provides 10 macrocells and operates with a maximum propagation delay of 7.5 ns. It is housed in a 28-pin Plastic Quad Flat Package (PQCC28), also designated as LCC-28. This component is designed for low-voltage applications within the standard GAL22V10 functional specification.

Programmable Logic Device Pld Feature Summary

• Utilizes E2CMOS technology for electrically erasable and programmable logic functionality.
• Supports In-System Programming (ISP) for flexible design updates without removal from the circuit board.
• Delivers a guaranteed maximum propagation delay of 7.5 ns.
• Contains 10 macrocells configured for complex combinational or registered logic operations.

Programmable Logic Device Pld Applications

• Replacement for legacy GAL22V10 devices in existing hardware designs.
• Implementation of address decoding and chip select logic in embedded systems.
• State machine implementation for industrial control interfaces.
• Bus protocol translation between different voltage domains.

Programmable Logic Device Pld Procurement Notes

Verify the suffix 'N' indicates the specific package variant and temperature grade during sourcing. Confirm RoHS compliance status as older revisions may differ. Ensure the supplier provides valid traceability documentation for the Lattice Semiconductor origin. Check for any specific handling requirements related to the PQCC28 plastic package during assembly.

Programmable Logic Device Pld Selection Notes

Select this model when a 7.5 ns speed grade is required for GAL22V10-compatible logic functions. The E2CMOS process allows for reprogramming, unlike one-time programmable alternatives. Consider the 28-pin LCC footprint for PCB layout compatibility. Verify that the system power supply aligns with the device's operating voltage specifications for reliable ISP operations.

Programmable Logic Device Pld Part Context

This part belongs to the ispGAL22V10 family, which bridges the gap between traditional GAL devices and modern CPLDs. It retains the pinout and logic structure of the classic GAL22V10 while adding non-volatile memory and ISP capabilities. The 'A' typically denotes advanced process technology, and 'V' indicates voltage characteristics within the Lattice nomenclature.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements include other variants within the GAL22V10 series, such as GAL22V10D-75LJ, provided speed grades match. Cross-family upgrades to Lattice MachXO or iCE40 devices require schematic redesign due to architectural differences. Verify that substitute parts support the same I/O drive strengths and voltage levels.
