• 5.0-V ISP capability through IEEE Std. 1149.1 JTAG interface
• Built-in JTAG boundary-scan test circuitry
• Open-drain output option available

Complex Programmable Logic Devices Applications

• PCI-compliant logic design
• High-speed data buffering
• Address decoding and bus interfacing

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm that the ordering suffix corresponds to the specific speed grade (-6) and package type (PQFP-100). Ensure storage conditions comply with humidity sensitivity requirements for EEPROM-based devices.

Complex Programmable Logic Devices Selection Notes

Select this model when 5.0-V supply voltage and ISP functionality are required. The -6 speed grade provides a 6 ns pin-to-pin delay suitable for moderate-speed applications. Verify that the 100-pin PQFP footprint matches the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000 family, which utilizes second-generation MAX architecture. The MAX 7000S variant specifically adds In-System Programmability and JTAG boundary-scan capabilities compared to standard MAX 7000 devices.
