EPM240ZM68C6N

Complex Programmable Logic Devices Overview

The Altera EPM240ZM68C6N is a MAX II series Complex Programmable Logic Device (CPLD) manufactured using 0.18μm CMOS technology. It features 240 logic elements and 192 macrocells, providing non-volatile configuration storage via integrated Flash memory that eliminates the need for external configuration devices. The device supports up to 52 I/O pins organized into two independent voltage domains, allowing flexible interface compatibility with various system components. It operates within a commercial temperature range of 0°C to 70°C and utilizes a 68-pin TFBGA package. Key electrical parameters include a maximum propagation delay of 7.5ns and an internal core voltage supply ranging from 1.71V to 1.89V.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture enables immediate operation upon power-up without external configuration memory.
• Dual voltage domain I/O banks support independent level standards such as LVCMOS and LVTTL.
• Integrated user-accessible Flash memory allows for small-scale data storage or parameter retention.
• System-in-Programmability (ISP) capability facilitates in-system programming via JTAG interfaces.

Complex Programmable Logic Devices Applications

• Logic glue functions in embedded systems
• Bus protocol conversion between different voltage levels
• Address decoding and control signal generation
• I/O expansion for microcontrollers

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix codes against official Intel/Altera documentation to confirm package type, speed grade, and environmental rating. Ensure the ordering part number matches the required commercial temperature range and pin count. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding labeling or manufacturing site changes before finalizing procurement orders.

Complex Programmable Logic Devices Selection Notes

Select this component when a simple, cost-effective solution for moderate logic density is required without the complexity of FPGA configuration flows. It is suitable for designs needing deterministic timing and low standby power. Consider the 68-pin package constraints for PCB layout and ensure the development environment supports legacy MAX II device families using older Quartus software versions.

Complex Programmable Logic Devices Part Context

This device belongs to the MAX II family, representing a transition point in Altera's CPLD portfolio towards lower power consumption and higher integration compared to previous generations. It serves as a drop-in replacement for many legacy GALs and simpler CPLDs in industrial and consumer electronics applications where non-vatility and ease of use are prioritized over high-speed parallel processing capabilities.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same package and pinout may be found within the EPM240 series variants differing only in speed grades or temperature ranges. Cross-family migration to newer MAX 10 devices requires significant design adaptation due to architectural differences and toolchain updates.
