EPM240GT100C5N

Complex Programmable Logic Devices Overview

The Altera EPM240GT100C5N is a MAX II series Complex Programmable Logic Device (CPLD) manufactured using 0.18μm CMOS Flash technology. It provides 240 logic elements and 192 macrocells within a 100-pin TQFP package. The device features an internal core voltage range of 1.71V to 1.89V and supports external I/O voltages of 3.3V, 2.5V, or 1.8V. Key electrical parameters include a maximum propagation delay of 4.7ns and a maximum operating frequency of 304 MHz. It operates within a commercial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture enables instant-on operation without external configuration memory.
• Supports System In-Programmability (ISP) via JTAG interface for field updates.
• MultiVolt I/O banks allow independent voltage domain configuration for mixed-signal interfaces.
• Includes 8Kbit user-accessible Flash memory for data storage.

Complex Programmable Logic Devices Applications

• Bus bridging and protocol conversion between different logic families.
• I/O expansion for microcontrollers and embedded processors.
• Power-on reset sequencing and system control logic.
• Address decoding and simple state machine implementation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C5N' against the manufacturer's current ordering guide to confirm availability status, as MAX II series components may have undergone lifecycle changes. Ensure the design utilizes Quartus II software versions compatible with MAX II devices, as newer toolchains may not support this family. Confirm RoHS compliance requirements match the 'N' suffix designation.

Complex Programmable Logic Devices Selection Notes

Select this model when non-vatility is required to eliminate external configuration Flash chips, reducing BOM cost and board space. Choose the TQFP-100 package if through-hole or standard surface-mount reflow processes are preferred over BGA. Verify that the 240 LE capacity meets the logic density needs, as higher performance variants like the EPM240T100C5N offer extended temperature ranges if industrial ratings are necessary.

Complex Programmable Logic Devices Part Context

This component belongs to the Altera MAX II family, which succeeded the MAX 7000 series. It represents a transition to lower power consumption while maintaining the ease of use associated with CPLDs. The part is widely used in legacy designs requiring reliable, low-cost programmable logic for glue logic applications.

Complex Programmable Logic Devices Replacement Considerations

For pin-compatible replacements, consider the EPM240T100C5N for industrial temperature range (-40°C to +85°C). Other MAX II variants with different package options (e.g., MBGA) share the same core logic but require PCB redesign. Cross-family migration to FPGA architectures requires significant logic restructuring.
