EPM240T100C5

Complex Programmable Logic Devices Overview

The Altera EPM240T100C5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX II series. It features 240 logic elements and 192 macrocells, housed in a 100-pin TQFP surface-mount package with an 80 I/O count. The device utilizes non-volatile Flash memory technology for instant-on operation. Electrical specifications include a maximum propagation delay of 4.7 ns and a maximum operating frequency of 304 MHz. It supports MultiVolt core voltages ranging from 2.375V to 2.625V or 3V to 3.6V, with I/O levels compatible with 3.3V, 2.5V, 1.8V, and 1.5V standards.

Complex Programmable Logic Devices Feature Summary

• Enhanced In-System Programming (ISP) compliant with IEEE Std. 1532.
• Integrated JTAG boundary scan test circuitry compliant with IEEE Std. 1149.1-1990.

Complex Programmable Logic Devices Applications

• Bus bridging and protocol conversion.
• I/O expansion for microprocessor systems.
• Power-on reset (POR) generation and timing control.
• Device configuration control.

Complex Programmable Logic Devices Part Context

The EPM240T100C5 is part of the MAX II family, designed for low-cost, low-power applications. This specific model represents the C5 speed grade within the 100-pin TQFP form factor. While the broader MAX II line remains active, this specific part number is listed as obsolete by major distributors such as Mouser, indicating it has been superseded by newer revisions or packages like the EPM240T100C5N.

Complex Programmable Logic Devices Replacement Considerations

Public documentation identifies the AGM AG256SL100 as a pin-compatible alternative. However, the AG256SL100 uses SRAM technology requiring an external SPI Flash, unlike the internal Flash of the EPM240T100C5. Engineers must verify power supply configurations, specifically VCCINT pin assignments, when migrating designs.
