The EPM7128SLC84-15W is a MAX 7000 series Programmable Logic Device (PLD) from Intel (formerly Altera). Similar to the EPM7128QC100-15, it features 128 macrocells, providing a high level of logic density suitable for complex digital designs. The 'SLC84' designation refers to the package type, which is an 84-pin PLCC (Plastic Leaded Chip Carrier). The '-15' indicates a 15ns propagation delay, representing the speed grade. The 'W' suffix often signifies a wide voltage range or a specific industrial temperature range.

Additional Details

The EPM7128SLC84-15W operates at a specific voltage range (typically 5V or 3.3V) and has specific timing characteristics that must be considered during design. The device is programmed using Altera's Quartus II software or other compatible programming tools. The datasheet is crucial for detailed specifications, including propagation delays, setup and hold times, and power consumption. The PLCC package allows for socketed mounting, which simplifies prototyping and replacement. 'W' often suggests compliance with specific environmental standards or a wider operating temperature range, making it suitable for more demanding applications. Proper PCB layout guidelines should be followed to minimize noise and ensure reliable operation.
