ISPGAL22V10AB-75LNI

Programmable Logic Device Pld Overview

The ispGAL22V10AB-75LNI is a discontinued Complex Programmable Logic Device (CPLD) from Lattice Semiconductor, belonging to the ispGAL22V10A family. It utilizes E²CMOS technology and operates at a core voltage of 2.5V. The device features 10 I/Os, 10 Output Logic Macrocells (OLMCs), and a programmable AND array with up to 44 product terms. Key electrical parameters include a maximum propagation delay of 7.5 ns, a typical standby power consumption under 300 µW, and support for IEEE 1149.1 boundary scan testing and IEEE 1532 in-system programming.

Programmable Logic Device Pld Feature Summary

• E²CMOS Technology: Combines CMOS logic with Electrically Erasable floating gate technology for high-speed operation and low standby power without turbo bits.
• Flexible OLMCs: Ten macrocells offer variable product term access (8 to 16 terms) and support both registered and combinatorial modes with individually programmable polarity.
• In-System Programming: Supports ISP via IEEE 1532 compliant interface and includes IEEE 1149.1 boundary scan testability for board-level verification.
• I/O Versatility: Features 5V tolerant inputs, open-drain capability, programmable slew rates, and configurable pull-up/pull-down resistors.

Programmable Logic Device Pld Applications

• DMA control
• State machine control
• High speed graphics processing
• Software-driven hardware configuration

Programmable Logic Device Pld Procurement Notes

All devices in the ispGAL22V10A family, including the ispGAL22V10AB-75LNI, have been officially discontinued per Product Change Notification (PCN) #09-10. Verification of part authenticity is critical when sourcing from secondary markets, as original manufacturing has ceased. Designers should confirm that legacy inventory meets functional requirements before integration.

Programmable Logic Device Pld Selection Notes

Select this component only for maintenance of existing designs requiring 2.5V core voltage and 28-pin PLCC packaging. The 'B' suffix denotes the 2.5V supply variant, while '75' indicates the 7.5 ns speed grade. Ensure compatibility with 3.3V or 5V I/O interfaces if required, as the device supports 5V tolerant inputs. Consider modern replacements due to discontinuation status.

Programmable Logic Device Pld Part Context

The ispGAL22V10AB-75LNI is part of the ispGAL22V10A series, which serves as a low-power successor to the GAL22V10 and ispGAL22LV10 families. It is functionally compatible with these earlier devices but offers enhanced features such as in-system programmability and lower power consumption through E²CMOS technology.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the datasheet. Discontinued models typically require migration to newer Lattice SPLD families or generic CPLDs with equivalent pin counts and logic resources.
