EPM7128EQC100-15

Complex Programmable Logic Devices Overview

The Altera EPM7128EQC100-15 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000E family. It features 128 macrocells, 8 logic array blocks (LABs), and 2,500 usable gates. The device operates at a nominal 5.0 V supply voltage with a maximum propagation delay of 7.5 ns and a counter frequency of 125 MHz. It is housed in a 100-pin PQFP package and provides up to 100 user I/O pins. This component supports MultiVolt I/O interface operation for compatibility with 3.3-V or 5.0-V devices.

• Replacement for discrete TTL/CMOS logic gates
• Data acquisition and sensor signal processing

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'QC' against official documentation to confirm package type and temperature range. Confirm availability status as this series may be discontinued or subject to end-of-life notices. Ensure design tools support the MAX 7000E family for programming and simulation.

Complex Programmable Logic Devices Selection Notes

Select this device when 128 macrocells are sufficient for the logic density requirements. Choose the -15 speed grade if a 7.5 ns delay and 125 MHz frequency meet system timing constraints. Consider the MAX 7000S variant if In-System Programming (ISP) via JTAG is required, as the standard MAX 7000E does not include ISP circuitry.

Complex Programmable Logic Devices Part Context

The EPM7128EQC100-15 is part of the MAX 7000E family, which offers enhanced features over the base MAX 7000 series, such as additional global clocking and output enable controls. It sits between the MAX 7000S (which adds ISP) and the MAX 7000A (which is 3.3V). It is designed for high-density integration of SSI, MSI, and LSI logic functions.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include other EPM7128 variants with different speed grades or packages. For ISP functionality, consider the EPM7128S series. For lower voltage operation, the MAX 7000A series is pin-compatible but requires 3.3V power.
