EPM7128SLC84-6N

Complex Programmable Logic Devices Overview

The EPM7128SLC84-6N is a Complex Programmable Logic Device (CPLD) from the Altera MAX 7000S family, fabricated using CMOS EEPROM technology. It integrates 128 macrocells organized into 8 logic array blocks (LABs), providing 2,500 usable gates and 68 user I/O pins in an 84-pin PLCC package. The device supports 5.0-V operation with In-System Programmability (ISP) via a JTAG interface. Key electrical parameters include a maximum pin-to-pin propagation delay of 6 ns, a minimum input setup time of 3.4 ns, and a counter frequency of 147.1 MHz.

• Built-in boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1

Complex Programmable Logic Devices Applications

• Address decoding and bus interfacing
• Signal processing and timing control
• Replacement for PALs, GALs, and standard PLDs

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number is discontinued. Check for moisture sensitivity indicators on packaging, as EEPROM devices are hygroscopic. Confirm that programming equipment supports the specific constant or adaptive algorithm variants if required by the design history.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 5.0-V logic compatibility and high-density programmability within an 84-pin footprint. Ensure the application utilizes the JTAG interface for programming, as this variant lacks alternative ISP methods. Compare against EPM7128E for non-ISP requirements or EPM7128A for 3.3-V voltage levels.

Complex Programmable Logic Devices Part Context

This component belongs to the MAX 7000S series, which enhances the base MAX 7000E features with in-system programmability. The 'S' suffix denotes ISP capability, 'LC' indicates the PLCC package type, and '84' specifies the pin count. The '-6N' suffix identifies the 6 ns speed grade and commercial temperature range.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other MAX 7000S devices such as EPM7128SLC84-10 or EPM7128SLC84-7. For higher density, consider EPM7160SLC84 variants. Note that MAX 7000A devices operate at 3.3 V and require voltage level translation.
