EPM240T100I5NAJ

Complex Programmable Logic Devices Overview

The Altera EPM240T100I5NAJ is a MAX II series Complex Programmable Logic Device (CPLD) manufactured by Intel. It features 240 logic elements and 192 macrocells, housed in a 100-pin TQFP package. The device utilizes non-volatile Flash technology for configuration storage, enabling immediate operation upon power-up without external configuration memory. It supports industrial temperature ranges (-40°C to +100°C) and offers flexible I/O voltage levels including 1.5V, 1.8V, 2.5V, and 3.3V across two independent banks. Key electrical parameters include a maximum propagation delay of 4.7ns and an internal kernel voltage of 2.5V.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture eliminates the need for external configuration chips.
• Industrial temperature rating (-40°C to +100°C) ensures reliability in harsh environments.
• Flexible I/O support with dual voltage domains (1.5V/1.8V/2.5V/3.3V).
• Integrated 8Kbit user Flash for small data storage or parameter retention.

Complex Programmable Logic Devices Applications

• Logic glue functions in embedded systems.
• Bus level translation between different voltage domains.
• Timing control and signal buffering.
• IO expansion for microcontrollers.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'AJ' against official Intel documentation, as standard datasheets typically list 'N' for lead-free compliance. Confirm the package type corresponds to TQFP-100 rather than MBGA variants found in similar model numbers. Ensure compatibility with legacy Quartus II software versions, as newer tools may not support this MAX II family.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required to simplify board design by removing external Flash memory. The 240 LE count is suitable for moderate complexity logic applications. Verify that the 100-pin TQFP package fits the PCB footprint constraints and that the thermal dissipation capabilities meet the system's power budget under industrial operating conditions.

Complex Programmable Logic Devices Part Context

This part belongs to the Intel MAX II family, which succeeded the MAX 7000 series with lower power consumption. The EPM240 designation indicates 240 logic elements. The 'T' denotes the TQFP package, '100' specifies the pin count, 'I5' indicates the industrial temperature range and speed grade, and 'N' signifies RoHS compliance. The 'AJ' suffix requires verification for specific tape-and-reel or packaging variations.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the MAX II family include EPM240T100C5N (commercial grade) or EPM240M100I5N (MBGA package). For upward compatibility, consider MAX V series devices, though these require external configuration memory. Verify pin-to-pin compatibility if substituting with other CPLD families.
