EPM1270T144C4

Complex Programmable Logic Devices Overview

The Altera EPM1270T144C4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 1270 logic elements and 980 macrocells within 127 Logic Array Blocks (LABs). The device operates at supply voltages of 2.5 V or 3.3 V, with a maximum operating frequency of 304 MHz and a typical propagation delay of 6.2 ns. It provides 116 I/O pins in a 144-pin TQFP package. Designed for industrial applications, it supports an extended temperature range from -40°C to +85°C and utilizes non-volatile Flash memory for configuration.

• Features non-volatile Flash technology for instant-on operation without external configuration devices.
• Operates on 2.5 V or 3.3 V power supplies with low static current consumption.

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems.
• Address decoding and bus bridging in embedded computing platforms.
• State machine implementation for communication protocol interfaces.
• General-purpose digital logic integration in consumer electronics.

Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'N' indicates RoHS compliance and lead-free status. Confirm the temperature grade 'C' corresponds to the commercial/industrial range (-40°C to +85°C). Ensure the package type matches the required 144-lead Thin Quad Flat Pack (TQFP) footprint. Check for specific revision levels if legacy design compatibility is critical.

Complex Programmable Logic Devices Selection Notes

Select this model when 1270 LEs are sufficient for the design complexity. Choose the TQFP-144 package for through-hole or surface-mount assembly requiring 116 accessible I/Os. Consider the C4 speed grade if timing constraints require a 6.2 ns maximum delay. Verify voltage requirements align with the 2.5 V or 3.3 V internal regulator capabilities.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II family, which succeeded the MAX 7000 series. It offers higher density and lower power consumption compared to earlier EEPROM-based CPLDs. The EPM1270 variant represents a mid-range density option within the series, balancing performance and pin count for versatile digital logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other EPM1270 variants with different speed grades (e.g., C3, C5) or packages (e.g., F256 for FBGA). Cross-family migration to MAX V or MAX 10 requires retiming and resource verification due to architectural differences.
