EPM1270GT144I5N

Complex Programmable Logic Devices Overview

The EPM1270GT144I5N is a Complex Programmable Logic Device (CPLD) from the Altera MAX II family. It features 1270 logic elements organized into 127 Logic Array Blocks (LABs) and provides 980 macrocells. The device utilizes non-volatile Flash memory for configuration, supporting in-system programmability. It operates with a supply voltage range of 1.71 V to 1.89 V at 1.8 V nominal. Key electrical parameters include a maximum operating frequency of 304 MHz and a typical propagation delay of 6.2 ns. The component is housed in a TQFP-144 surface-mount package and supports an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash memory architecture enabling instant-on operation and high endurance.
• High-performance logic fabric with 127 LABs, 980 macrocells, and 116 I/O pins.
• Supports System In-Programmability (SIP) via JTAG interface.
• Operates within a 1.8 V power domain (1.71 V–1.89 V) with low static current consumption.

Complex Programmable Logic Devices Applications

• Bus bridging and protocol conversion in embedded systems.
• Address decoding and control logic generation.
• State machine implementation for industrial automation controllers.
• Interface adaptation between legacy components and modern digital systems.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I5N' against the manufacturer's official datasheet to confirm the industrial temperature grade (-40°C to +85°C) and pinout compatibility. Ensure that the design accounts for the 1.8 V core voltage requirements and appropriate decoupling capacitors near the VCC pins. Confirm RoHS compliance status through the latest production change notices provided by the manufacturer.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile storage is required to eliminate external configuration EEPROMs. Compare the 1270 logic element count against project complexity; if higher density is needed, consider larger packages in the same series. Verify that the 116 available I/O pins meet the interface requirements, noting that not all pins may be usable for general purpose I/O depending on the selected functionality.

Complex Programmable Logic Devices Part Context

This component belongs to the Altera MAX II CPLD series, designed as a cost-effective solution for low-to-medium density logic applications. It serves as a successor to earlier EPMA/EPMM series devices, offering improved performance and lower power consumption while maintaining backward compatibility with existing design tools like Quartus II. The TQFP-144 package provides a balance between pin count and physical footprint for board-level integration.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same series include EPM1270T144I5N (if temperature grades align) or EPM1270GT144C5N for commercial temperature variants. Cross-family migration to MAX V (e.g., 5M1270ZT144I5N) requires schematic and code re-verification due to architectural differences in logic blocks and I/O standards.
