EPM240GT100C4

Complex Programmable Logic Devices Overview

The Altera EPM240GT100C4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 240 logic elements, 192 macrocells, and 80 I/O pins housed in a 100-TQFP package. The device operates with an internal supply voltage ranging from 1.71V to 1.89V and supports system-in-programmability via JTAG. Key electrical parameters include a maximum propagation delay of 4.7 ns and a maximum operating frequency of 304 MHz. It utilizes Flash memory technology for non-volatile storage and functions within a commercial temperature range of 0°C to 70°C or 85°C depending on specific suffix variations.

Complex Programmable Logic Devices Feature Summary

• Contains 240 logic elements organized into 24 Logic Array Blocks (LABs) with 192 macrocells.
• Supports System-In-Programmability (SIP) and IEEE 1149.1 (JTAG) boundary scan testing.
• Utilizes non-volatile Flash memory technology for configuration retention without external battery.
• Offers high-speed performance with a maximum propagation delay of 4.7 ns and frequency up to 304 MHz.

Complex Programmable Logic Devices Applications

• Wireless data reception platforms requiring baseband interface control and data buffering.
• Digital logic systems needing flexible I/O expansion and protocol conversion.
• Industrial control applications utilizing JTAG-based debugging and reconfiguration.
• General-purpose programmable logic for timing generation and signal interfacing.

Complex Programmable Logic Devices Procurement Notes

Verify the complete part number including the temperature grade suffix (e.g., C4N for commercial, I5N for industrial) as specifications vary significantly between grades. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for surface mount assembly processes. Check for any Product Change Notices regarding labeling or packaging updates before ordering.

Complex Programmable Logic Devices Selection Notes

Select the EPM240GT100C4N when 240 logic elements and 80 I/Os are sufficient for the design. Ensure the chosen temperature suffix matches the operational environment; 'C' variants typically support 0°C to 70°C or 85°C, while 'I' variants support -40°C to 85°C. Verify that the 100-TQFP package dimensions fit the PCB footprint constraints and that the 1.8V core voltage aligns with the system power budget.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II family, designed for low-cost, low-power CPLD applications. It serves as a successor to older GAL and PAL devices, offering higher density and reprogrammability. The 'EPM240' designation indicates the logic capacity, while 'GT' signifies the Flash-based technology and TQFP package type.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same package and pinout include other MAX II devices such as EPM240T100C4N or EPM240T100I5N. For higher density needs, consider the EPM570 series, though pin compatibility must be verified. Cross-family migration to Cyclone FPGAs requires significant redesign due to architectural differences.
