EPM7160ELC84-20

Complex Programmable Logic Devices Overview

The Altera EPM7160ELC84-20 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000E family. It features 160 macrocells organized into 10 logic array blocks and provides 64 user I/O pins within an 84-pin PLCC package. The device operates at a 5.0 V supply voltage with a maximum propagation delay of 10 ns and a maximum counter frequency of 100 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration, allowing reprogramming up to 100 times.

Complex Programmable Logic Devices Feature Summary

• MAX 7000E architecture with 160 macrocells and 3,200 usable gates
• 10 ns maximum pin-to-pin propagation delay
• EEPROM-based non-volatile storage supporting 100 erase/program cycles
• Enhanced features including programmable slew-rate control and fast input registers

Complex Programmable Logic Devices Applications

• High-density digital logic integration replacing PALs, GALs, and standard SSI/MSI components
• System controller functions in mixed-voltage environments using MultiVolt I/O capability
• Prototyping and design verification for complex sequential and combinatorial logic circuits

Complex Programmable Logic Devices Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Verification of authenticity is critical when sourcing from secondary markets due to the age of the product. Buyers must confirm the specific speed grade suffix (-20) and package type (LC84) match system requirements, as functional equivalents may require retiming analysis.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring 160 macrocells with 5V operation and EEPROM retention. The -20 speed grade indicates a 10 ns delay; faster grades like -10 are available if timing constraints allow. Ensure the PCB layout supports the PLCC-84 footprint and that the design toolchain supports the MAX 7000E architecture for proper place-and-route.

Complex Programmable Logic Devices Part Context

The EPM7160ELC84-20 is part of the MAX 7000E series, which offers enhanced features over the base MAX 7000 line, such as additional global clocks and output enables. It sits between the lower-density EPM7128E and higher-density EPM7192E in the product lineup, serving as a mid-range solution for dense logic applications before the introduction of ISP-capable MAX 7000S devices.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other MAX 7000E variants such as the EPM7160ELC84-10 or EPM7160ELC84-7, provided the timing specifications meet the design requirements. For modern replacements, Intel/Altera MAX 10 or Cyclone IV FPGAs may be considered, though these require significant architectural redesign.
