Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment prior to installation. Ensure handling procedures account for moisture sensitivity levels as specified in the datasheet. Validate that the specific speed grade (-10) meets timing requirements for the target application design.

Complex Programmable Logic Devices Selection Notes

Select this model when high gate density (10,000 gates) and extensive I/O count (208 pins) are required within the MAX 3000A family. The -10 speed grade provides a 7.5 ns delay suitable for moderate-speed synchronous designs. Consider the 3.3-V core voltage and MultiVolt I/O capabilities if interfacing with mixed-voltage peripherals. Verify that the 208-pin PQFP package fits the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 3000A series, which succeeded the original MAX 3000 family. It shares architectural similarities with other devices in the series, such as the EPM3256A, but offers higher capacity. The MAX 3000A family is characterized by its EEPROM-based technology, allowing for unlimited reprogramming and in-system configurability without external voltage generators.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements within the same family include the EPM3512A variant with different speed grades or packages. Cross-family migration may require architectural adjustments. Verify pin compatibility and timing specifications before substituting with other CPLD manufacturers' products.
