ISPGAL22V10AV-75LNN

Programmable Logic Device Pld Overview

The ISPGAL22V10AV-75LNN is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, belonging to the ispGAL22V10A family. It utilizes low-voltage E2CMOS technology with a 3.3V core supply and supports 3.3V LVCMOS I/O standards. The device features ten Output Logic Macrocells (OLMCs), In-System Programmability (ISP) via IEEE 1149.1 and IEEE 1532 interfaces, and hot-socketing capability. Key electrical parameters include a maximum propagation delay of 7.5 ns, a typical standby power consumption under 300 µW, and an erase/reprogram cycle endurance of 1,000 cycles.

Programmable Logic Device Pld Feature Summary

• In-System Programmability (ISP) compliant with IEEE 1149.1 boundary scan and IEEE 1532 programming standards.
• Low-power E2CMOS architecture with 3.3V core voltage and 5V tolerant I/O for 3.3V interface compatibility.
• Hot-socketing support allowing tolerance of active signals during power-up and power-down sequences.
• Programmable output slew rate control and open-drain capability on individual outputs.

Programmable Logic Device Pld Applications

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

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor pursuant to Product Change Notification (PCN) #09-10. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Designers must confirm that any sourced units match the specific lead-free QFN package designation indicated by the 'NN' suffix.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy design compatibility with the ispGAL22LV10 or GAL22V10 families is required. Ensure the system operates within the 3.0V to 3.6V VCC range. For new designs, consider modern replacements as this device is no longer in production. Verify that the 32-pin QFN/QFNS package dimensions fit the target PCB layout, noting that the QFN package was also subject to discontinuance via PCN #13A-08.

Programmable Logic Device Pld Part Context

The ISPGAL22V10AV-75LNN belongs to the ispGAL22V10A series, which offers high-performance SPLDs with fast pin-to-pin speeds. The 'AV' indicates a 3.3V supply variant, '75' denotes the 7.5 ns speed grade, 'L' signifies low power, 'J' or 'N' refers to the package type (though 'NN' specifies lead-free QFN), and 'I' would indicate industrial grade (absent here, implying commercial grade). This family bridges the gap between traditional GAL devices and more complex CPLDs.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult Lattice Semiconductor's current portfolio for equivalent functionality in terms of macrocell count and I/O capabilities.

Programmable Logic Device Pld FAQ

What is the maximum operating frequency for the ISPGAL22V10AV-75LNN?

The maximum operating frequency (fMAX) with no feedback is 166 MHz. With internal feedback, it is 133 MHz, and with external feedback, it is 100 MHz.

Does the ISPGAL22V10AV-75LNN support hot-socketing?

Yes, the device supports hot-socketing. It can tolerate active signals on I/Os and inputs during power-up and power-down without damage, provided input voltages remain within the 0V to 3.0V range.

How many product terms are available per Output Logic Macrocell (OLMC)?

The number of product terms varies by OLMC position: two OLMCs have 8 terms, two have 10, two have 12, two have 14, and two have 16 terms. Each OLMC also has one dedicated term for output enable control.
