EPM1270T144C3RR

Complex Programmable Logic Devices Overview

The EPM1270T144C3RR is a Complex Programmable Logic Device (CPLD) belonging to the Altera MAX II family. It features 1270 logic elements and 980 macrocells, housed in a 144-pin TQFP package with 116 I/Os. The device supports system-in-programmability via Flash memory technology and operates on internal voltages of 2.5V or 3.3V. Key electrical specifications include a maximum propagation delay of 6.2 ns and a maximum operating frequency of 304 MHz. It is designed for surface-mount installation within an industrial temperature range of 0°C to 85°C.

Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'RR' against official manufacturer documentation to confirm if it denotes a specific tape-and-reel packaging variant or a restricted distribution channel. Standard datasheets typically list 'EPM1270T144C3N'. Ensure the supplier provides valid traceability documents and RoHS compliance certificates matching the specific batch code.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration without external boot ROM is required. Compare the 6.2 ns delay against timing requirements of the target clock domain. Verify that the 144-pin TQFP footprint matches the PCB layout constraints and that the 3.3V/2.5V I/O standards are compatible with connected peripherals.

Complex Programmable Logic Devices Part Context

This part is a member of the MAX II family, which succeeded the MAX VII series. It offers higher capacity per dollar compared to previous generations while maintaining lower power dissipation. The EPM1270 variant specifically targets applications requiring moderate logic density with simple programming interfaces.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package may include other MAX II devices with equal or higher macrocell counts, such as the EPM1270T144C5N. Cross-family migration to MAX V requires re-evaluation of programming interfaces and I/O standards.
