EPM240GM100I5N

Complex Programmable Logic Devices Overview

The Altera EPM240GM100I5N is a MAX II series Complex Programmable Logic Device (CPLD) manufactured using 0.18μm CMOS technology. It features 240 logic elements and 192 macrocells, housed in a 100-pin M-MBGA package measuring 6x6 mm. The device operates with an internal core voltage of 1.71V to 1.89V and supports I/O voltages of 1.5V, 1.8V, 2.5V, or 3.3V across two independent banks. Key electrical parameters include a maximum propagation delay of 4.7 ns and a maximum operating frequency of 304 MHz. It includes 8 Kbit of user-accessible Flash memory for data storage. The component is rated for industrial temperature ranges from -40°C to +100°C junction temperature.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture enables immediate operation upon power-up without external configuration memory.
• Dual voltage domain I/O banks support flexible interfacing with LVCMOS and LVTTL standards.
• Integrated 8 Kbit user Flash allows on-chip storage of configuration parameters or serial numbers.
• Industrial grade reliability with a wide operating temperature range of -40°C to +100°C.

Complex Programmable Logic Devices Applications

• Logic glue and bus conversion in industrial control systems.
• Timing control and address decoding in embedded devices.
• IO expansion for microcontrollers and legacy interface bridging.
• Low-power portable equipment requiring non-vatile logic configuration.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'GM' indicates the M-MBGA package variant distinct from other pinouts like TQFP or GT. Confirm RoHS compliance status as 'N' suffix typically denotes lead-free construction. Ensure design files use Quartus II versions up to 13.1, as newer Quartus Prime software does not support the MAX II family. Check for moisture sensitivity level (MSL 3) handling requirements during assembly.

Complex Programmable Logic Devices Selection Notes

Select this model when 240 LEs are sufficient for the design logic density. Choose the GM package for space-constrained PCB layouts requiring a 6x6 mm footprint. Verify that the application requires industrial temperature stability (-40°C to +100°C); if commercial grade (0°C to +70°C) is acceptable, consider the C5N variant. Ensure the design utilizes JTAG for in-system programming capabilities.

Complex Programmable Logic Devices Part Context

This component belongs to the Intel (formerly Altera) MAX II family, which succeeded the MAX 7000 series. It represents a transition to lower power consumption while maintaining non-volatile configuration. The EPM240GM100I5N is part of the 240-LE tier, offering a balance between cost and logic capacity for small-scale programmable logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the end-of-life status of many MAX II parts. Functionally equivalent alternatives may include the EPM240T100I5N (TQFP package, different form factor) or EPM240GT100I5N (TQFP package). Cross-package substitution requires PCB redesign. No direct drop-in replacement exists for the MBGA package in current active production lines.
