EPM7256EGI192-15

Complex Programmable Logic Devices Overview

The Altera EPM7256EGI192-15 is a MAX 7000E series EEPROM-based programmable logic device (PLD) housed in a 192-pin PGA package. It features 256 macrocells organized into 16 Logic Array Blocks, providing 5,000 usable gates and up to 164 user I/O pins. Key electrical parameters include a maximum pin-to-pin delay of 12 ns, a setup time of 7 ns, and a counter frequency of 90.9 MHz. The device supports MultiVolt I/O for 3.3-V or 5.0-V operation and includes enhanced features such as two global clocks, six output enables, fast input registers, and programmable slew-rate control.

Complex Programmable Logic Devices Feature Summary

• 256 macrocells with 5,000 usable gates across 16 Logic Array Blocks
• 12 ns maximum pin-to-pin delay and 90.9 MHz counter frequency
• MultiVolt I/O interface supporting 3.3-V and 5.0-V mixed-voltage systems
• Enhanced architecture with two global clocks, six output enables, and programmable slew-rate control

Complex Programmable Logic Devices Applications

• High-density integration of SSI, MSI, and LSI logic functions
• Replacement for PALs, GALs, and pLSI devices in complex digital designs
• Mixed-voltage system interfacing requiring 3.3-V/5.0-V compatibility

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix 'EGI' corresponds to the 192-pin Ceramic Pin-Grid Array (PGA) package and -15 speed grade. Confirm that the specific revision matches the MAX 7000E family specifications, particularly regarding the absence of In-System Programmability (ISP), which is reserved for MAX 7000S variants. Ensure design files account for the 164 maximum user I/O pins available in this package configuration.

Complex Programmable Logic Devices Selection Notes

Select this component when 256 macrocells are required without the need for JTAG-based in-system programming. The -15 speed grade offers a 12 ns delay suitable for moderate-speed applications. Consider the MAX 7000S variant if ISP via IEEE Std. 1149.1 is necessary. Verify that the 192-pin PGA footprint fits the target PCB layout constraints and thermal requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000E family, characterized by enhanced interconnect resources and additional global control signals compared to the base MAX 7000 series. Unlike the MAX 7000S devices, it lacks built-in JTAG boundary-scan test circuitry and ISP capabilities. It is designed for high-performance applications requiring reprogrammability during development but not necessarily in-field updates.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same density include other MAX 7000E devices in different packages, provided the pin count matches. For ISP functionality, the EPM7256S series is the functional equivalent but requires verification of software toolchain support for JTAG programming.
