EPM7512AEQC208-7

Complex Programmable Logic Devices Overview

The Altera EPM7512AEQC208-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 512 macrocells organized into 32 Logic Array Blocks (LABs), providing approximately 10,000 usable gates. The device operates at a maximum frequency of 116.3 MHz with a typical propagation delay of 7.5 ns. It utilizes an EEPROM technology for non-volatile configuration and supports In-System Programming (ISP) via JTAG. The component is housed in a 208-pin Plastic Quad Flat Package (PQFP) and functions within a supply voltage range of 3.0 V to 3.6 V.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-7) against official datasheets to confirm timing characteristics. Confirm RoHS compliance status as older manufacturing runs may differ. Check for obsolescence notices from Intel/Altera, as this legacy CPLD series may have limited availability or require alternative sourcing strategies.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are required with a 208-pin footprint. Ensure the design accommodates the 3.3V I/O levels compatible with 2.5V/3.3V/5V tolerant pins. Verify that the PCB layout supports the PQFP-208 package dimensions and thermal requirements for the specified operating temperature range.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000A series, an evolution of the original MAX 7000 line. It shares architectural similarities with variants like the EPM7512AEQC208-10 but offers faster switching speeds. The series is characterized by its high density for CPLDs and robust ISP capabilities, widely used in legacy designs before migration to FPGA technologies.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade are limited due to the end-of-life status of many MAX 7000 variants. Review the EPM7512AEQC208-10 for slower speed compatibility if available. Consider modern FPGA alternatives from Intel or Lattice for new designs requiring equivalent logic density.
