EPM7256SRC208-15

Complex Programmable Logic Devices Overview

The EPM7256SRC208-15 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family, fabricated using CMOS EEPROM technology. It provides 5,000 usable gates and 256 macrocells organized into 16 logic array blocks. The device supports in-system programming via a JTAG interface and features 164 user I/O pins within a 208-pin PQFP package. Electrical specifications include a maximum propagation delay of 7.5 ns, a setup time of 3.9 ns, and a counter frequency of 128.2 MHz. It operates at 5.0 V with MultiVolt I/O capabilities.

Complex Programmable Logic Devices Feature Summary

• In-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface
• Built-in JTAG boundary-scan test circuitry for devices with 128+ macrocells
• MultiVolt I/O interface supporting 3.3-V or 5.0-V operation
• Programmable speed/power optimization with power-saving mode

Complex Programmable Logic Devices Applications

• High-density integration of SSI, MSI, and LSI logic functions
• PCI-compliant system designs
• Replacement for PALs, GALs, and discrete gate circuits
• Mixed-voltage system interfacing

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'SRC' against official manufacturer documentation to confirm package type and speed grade accuracy. Ensure compatibility with 5.0 V ISP programming hardware such as MasterBlaster or ByteBlasterMV cables. Confirm that the design environment supports the MAX 7000S architecture features.

Complex Programmable Logic Devices Selection Notes

Select this device when high-density logic replacement is required with in-system reprogrammability. The MAX 7000S family offers enhanced interconnect resources and fast input registers compared to standard MAX 7000 devices. Consider the 208-pin PQFP package constraints and 5.0 V supply requirements during board layout.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000S series, which extends the MAX 7000E architecture with ISP capabilities. It is designed for applications requiring non-volatile configuration and rapid design iteration without removing the device from the PCB.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements exist within the MAX 7000A and MAX 7000B low-voltage families, though voltage levels differ. Verify that any substitute supports the required 5.0 V ISP functionality if in-system programming is necessary.
