EPM7128EQC100-20YY

Complex Programmable Logic Devices Overview

The EPM7128EQC100-20YY is a Complex Programmable Logic Device (CPLD) from the Altera MAX 7000E family. It features 128 macrocells, 8 logic array blocks, and 2,500 usable gates. The device operates at a maximum frequency of 125 MHz with a pin-to-pin propagation delay of 7.5 ns. It utilizes CMOS EEPROM technology for non-volatile configuration and supports 5.0 V operation. The component is housed in a PQFP-100 package, providing up to 100 user I/O pins. It includes enhanced features such as programmable slew-rate control, six global output enables, two global clocks, and fast input registers.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'YY' against official manufacturer documentation, as standard datasheets typically list suffixes like '-20' for speed grade. Confirm current lifecycle status, as many MAX 7000 devices are discontinued or Not Recommended for New Designs. Ensure compatibility with existing PCB footprints for the PQFP-100 package.

Complex Programmable Logic Devices Selection Notes

Select this device when high-density logic replacement is required without the complexity of an FPGA. The MAX 7000E series offers deterministic timing due to its fixed interconnect array. Consider the 7.5 ns delay and 125 MHz limit for high-speed applications. Verify voltage requirements, as this specific part is a 5.0 V device, unlike the later MAX 7000A series which supports 3.3 V.

Complex Programmable Logic Devices Part Context

The EPM7128EQC100-20YY belongs to the MAX 7000E family, representing an enhancement over the original MAX 7000 series with additional global controls and slew-rate options. It sits between the basic MAX 7000 and the ISP-capable MAX 7000S series. This generation was widely used in industrial and communication equipment before being superseded by MAX 7000A and newer families.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may be limited due to the legacy status of the MAX 7000E family. Check for MAX 7000A equivalents if 3.3 V operation is acceptable, noting that voltage levels differ. For new designs, consider modern CPLDs or FPGAs with similar logic density and I/O counts.
