EPM240T100I5TT

Complex Programmable Logic Devices Overview

The EPM240T100I5TT is a Complex Programmable Logic Device (CPLD) belonging to the Intel MAX II family. It features 240 logic elements and 192 macrocells, fabricated using 0.18μm CMOS technology. The device integrates 8Kbit of non-volatile Flash memory for configuration storage, enabling immediate operation upon power-up without external configuration chips. It supports up to 80 user I/Os with MultiVolt capability, allowing independent voltage domains for VCCIO (1.5V, 1.8V, 2.5V, or 3.3V) and a core voltage of 2.5V. The component operates within an industrial temperature range of -40°C to +100°C and utilizes a 100-pin TQFP package.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture provides instant-on functionality and retains configuration without power.
• MultiVolt I/O banks support multiple voltage standards including LVCMOS and LVTTL.
• Industrial temperature rating (-40°C to +100°C) ensures reliability in harsh environments.
• In-system programmability (ISP) via JTAG interface allows field updates.

Complex Programmable Logic Devices Applications

• Bus bridging and protocol conversion between different voltage domains.
• I/O expansion for microcontrollers and embedded processors.
• Power-on reset generation and sequencing control.
• Logic glue functions in industrial automation systems.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TT' against official Intel/Altera documentation, as standard listings typically use 'I5N' or 'I5'. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for this specific variant may vary. Ensure the ordering part number matches the exact package and temperature grade required for the design.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required to eliminate external Flash memory costs. The MAX II series is suitable for designs needing moderate logic density (240 LEs) with flexible I/O voltage levels. Consider the TQFP-100 package constraints regarding thermal dissipation and PCB space compared to BGA alternatives.

Complex Programmable Logic Devices Part Context

This device is part of the Altera MAX II family, which succeeded the MAX 7000 series. Intel acquired Altera, and these devices are now manufactured under Intel's portfolio. The MAX II line focuses on low-power, cost-effective solutions for small-scale logic applications, bridging the gap between simple PALs/GALs and high-end FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements from other manufacturers are rare due to proprietary architecture. Some domestic CPLDs like the AGM AG256SL100 offer physical compatibility but require careful verification of electrical parameters and pin function mapping before substitution.
