EPM240GT100C3N

Complex Programmable Logic Devices Overview

The Altera EPM240GT100C3N is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 240 logic elements organized into 24 Logic Array Blocks (LABs) and provides 192 macrocells with 80 available I/O pins. The device utilizes Flash memory technology for non-volatile configuration storage, eliminating the need for external configuration devices. It operates within a supply voltage range of 1.71 V to 1.89 V, typically at 1.8 V, and supports a maximum operating frequency of 304 MHz with a maximum propagation delay of 4.7 ns. The component is housed in a 100-pin TQFP package and is rated for commercial temperature operation from 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C3N' against the official Intel/Altera MAX II ordering guide to confirm the exact speed grade, temperature range, and package variant. Ensure that the source documentation explicitly lists this part number as active or available, as older CPLD families may have undergone lifecycle changes. Confirm RoHS compliance status through the manufacturer's current product availability page rather than relying on distributor listings alone.

Complex Programmable Logic Devices Selection Notes

Select this component when a design requires non-volatile programmability with low static power consumption and moderate logic density. The 1.8 V core voltage necessitates careful attention to I/O voltage levels if interfacing with 3.3 V systems, requiring appropriate level shifting or selection of compatible I/O standards. Compare the 240 LE count against alternative MAX II variants like the EPM570 for higher density needs or smaller packages for reduced pin counts.

Complex Programmable Logic Devices Part Context

The EPM240GT100C3N is part of the Intel MAX II family, which succeeded earlier MAX/VHDL-based CPLDs by integrating Flash memory directly onto the die. This integration simplified board design by removing the requirement for separate configuration PROMs. The MAX II series is widely used in cost-sensitive applications requiring reprogrammability, such as consumer electronics and industrial automation controllers.
