EPM240F100C4N

Complex Programmable Logic Devices Overview

The Altera EPM240F100C4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 240 logic elements and 192 macrocells, housed in a 100-pin FBGA package measuring 11x11 mm. The device supports system-in-programmability via JTAG and operates with internal supply voltages of 2.5V and 3.3V. Key electrical parameters include a maximum propagation delay of 4.7 ns and an operating temperature range of 0°C to 85°C TJ. It integrates non-volatile Flash configuration memory, eliminating the need for external configuration devices.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture allows immediate operation upon power-up without external configuration chips.
• Supports In-System Programming (ISP) via JTAG interface for flexible field updates.
• Dual voltage domain capability with VCCINT at 2.5V and configurable VCCIO levels.
• Integrated 8Kbit user-accessible Flash memory for data storage.

Complex Programmable Logic Devices Applications

• Logic glue functions in embedded systems
• Bus level translation between different voltage domains
• Simple state machine implementation
• I/O expansion for microcontrollers

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C4N' against official datasheets to confirm the commercial temperature grade (0°C to 85°C) and FBGA packaging. Ensure compatibility with legacy Quartus II software versions, as newer tools may not support this MAX II series component. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile configuration is required to reduce board space and BOM cost compared to volatile FPGAs. The 240 LE count suits low-complexity logic tasks. Verify that the 100-FBGA footprint fits the PCB design constraints, noting the 0.5mm ball pitch. Ensure the design can accommodate the 2.5V core voltage requirement alongside the I/O voltage needs.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II family, which succeeded the MAX 7000 series with improved power efficiency. The EPM240 variant represents the entry-level density within this family. The 'F' designation indicates the FBGA package type, while 'C4' specifies the commercial temperature range and speed grade. Intel acquired Altera, but these parts remain distinct from the Cyclone or Arria FPGA lines.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be verified against the MAX II Device Order Guide. Upgrading to higher density variants like EPM570 requires schematic and layout changes due to different pin counts or logic resources. Cross-family migration to Cyclone devices is not a direct replacement due to architectural differences.
