EPM240T100I5

Complex Programmable Logic Devices Overview

The EPM240T100I5 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 operates with an internal core voltage of 2.5V and supports I/O voltages of 3.3V. It offers up to 80 user I/Os and includes 8Kbit of embedded Flash memory for configuration and data storage. Key electrical parameters include a maximum propagation delay of 7.5ns and a maximum operating frequency of 201.1MHz. The component utilizes non-volatile Flash architecture, enabling immediate operation upon power-up without external configuration devices.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture eliminates the need for external configuration memory.
• Supports multiple I/O standards including LVCMOS and LVTTL across independent voltage banks.
• Integrated 8Kbit user-accessible Flash for persistent data storage.
• System-in-Programmability (ISP) capability via JTAG interface.

Complex Programmable Logic Devices Applications

• Bus protocol conversion between different voltage domains.
• Timing control and glue logic in embedded systems.
• General-purpose I/O expansion for microcontrollers.
• Address decoding and chip select generation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I5' confirms industrial temperature range (-40°C to +100°C). Confirm package type TQFP-100 matches design requirements. Check RoHS compliance status as indicated by manufacturer documentation. Ensure Quartus II software version compatibility for legacy MAX II support.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile configuration is required to reduce BOM cost. Compare propagation delay specifications against timing constraints. Verify I/O bank voltage compatibility with connected peripherals. Consider thermal performance within the industrial temperature range if operating near limits.

Complex Programmable Logic Devices Part Context

This part is part of the Intel MAX II series, designed for low-cost, low-power applications. It serves as a successor to older GAL and MAX 7000 families, offering higher density and lower power consumption. The MAX II line is characterized by its embedded Flash technology, distinguishing it from volatile SRAM-based FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be verified against official substitution lists. Cross-family migration to MAX 10 or Agilex requires significant redesign due to architectural differences.
