EPM7256EQC160-12

Complex Programmable Logic Devices Overview

The EPM7256EQC160-12 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000E family, manufactured by Altera. It features 256 macrocells organized into 16 logic array blocks and provides up to 5,000 usable gates. The device operates at a standard 5.0 V supply voltage with a maximum operating frequency of 90.9 MHz and a typical pin-to-pin propagation delay of 12 ns. It is housed in a 160-pin Plastic Quad Flat Pack (PQFP) package and supports MultiVolt I/O interface operation for compatibility with both 3.3-V and 5.0-V systems.

Complex Programmable Logic Devices Feature Summary

• MAX 7000E architecture with 256 macrocells, 16 LABs, and 5,000 usable gates
• Enhanced features including two global clock signals, six output enables, and programmable slew-rate control
• MultiVolt I/O capability allowing interface with 3.3-V or 5.0-V devices
• EEPROM-based non-volatile storage supporting reprogramming

Complex Programmable Logic Devices Applications

• High-density integration of SSI, MSI, and LSI logic functions
• Replacement for PALs, GALs, and discrete gate circuits
• Complex address decoding and bus interfacing
• State machine implementation and timing control

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated on specific product labels. Ensure handling procedures account for moisture sensitivity levels appropriate for PQFP packages during storage and assembly.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require 256 macrocells within a 160-pin PQFP footprint. The -12 speed grade offers a 12 ns delay suitable for applications running below 90.9 MHz. Consider MAX 7000S variants if In-System Programming via JTAG is required, as the E variant lacks ISP capabilities.

Complex Programmable Logic Devices Part Context

This component is part of the second-generation MAX 7000 family, which utilizes CMOS EEPROM technology. The MAX 7000E series specifically adds enhanced routing resources, additional global clocks, and output enable controls compared to the base MAX 7000 devices, improving design routability and performance.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other speed grades within the EPM7256E series, such as EPM7256EQC160-10 or EPM7256EQC160-15, provided timing requirements are met. For ISP functionality, consider the EPM7256SQC160-10N from the MAX 7000S family.
