EPM240T100I5NGA

Complex Programmable Logic Devices Overview

The Altera EPM240T100I5NGA is a MAX II series Complex Programmable Logic Device (CPLD) manufactured by Intel. It features 240 logic elements and 192 macrocells within a 100-pin TQFP package. The device utilizes non-volatile Flash technology for configuration, eliminating the need for external memory. Key electrical specifications include a maximum propagation delay of 4.7 ns and an internal kernel voltage of 2.5 V. It supports I/O voltages of 1.5 V, 1.8 V, 2.5 V, or 3.3 V across two independent banks. The industrial temperature grade ensures operation from -40°C to +100°C.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture provides immediate power-up operation without external configuration chips.
• Integrated 8 Kbit user Flash allows storage of small data sets such as serial numbers or calibration parameters.
• Dual voltage domain I/O banks support flexible interfacing with various logic families including LVCMOS and LVTTL.
• Four global clock networks enable precise timing control for synchronous designs.

Complex Programmable Logic Devices Applications

• Bus protocol conversion between different voltage domains.
• Timing control and glue logic in embedded systems.
• IO expansion for microcontrollers and processors.
• Address decoding and chip select generation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'GA' against official Intel documentation, as standard datasheets typically list 'N' for lead-free compliance. Confirm availability through authorized distributors, noting that older MAX II components may have limited stock or longer lead times due to lifecycle status. Ensure the supplier provides valid traceability documents.

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 functions. Verify that the 100-pin TQFP package fits the PCB footprint constraints and that the thermal requirements for the industrial grade (-40°C to +100°C) are met by the application environment.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX II family, which was acquired by Intel. It serves as a low-cost, low-power alternative to traditional EEPROM-based CPLDs and smaller FPGAs. The MAX II series is designed for applications requiring simple programmable logic with instant-on capabilities and high reliability in industrial environments.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed pin-compatible substitutes include the AG256SL100 from Agamatrix Microelectronics. Note that while pin-compatible, the AG256SL100 uses SRAM technology requiring an external SPI Flash, differing from the integrated Flash of the EPM240T100I5NGA.
