5M1270ZT144A5N

Overview

The Altera 5M1270ZT144A5N is a MAX V series Complex Programmable Logic Device (CPLD) housed in a 144-pin TQFP package. It features 980 macrocells, 127 logic array blocks (LABs), and 116 I/O pins. The device operates on a single 1.8V supply voltage with a maximum frequency of 201.1 MHz and a typical propagation delay of 6.2 ns. It utilizes non-volatile Flash memory for configuration, supporting system-in-system programming. The component is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• MAX V architecture with 980 macrocells and 127 LABs
• Single 1.8V power supply operation
• Non-volatile Flash configuration memory
• System-in-System Programming (SISP) capability

Applications

• Low-power embedded control applications
• Interface bridging between different voltage domains
• Address decoding and simple state machine implementation
• Replacement for legacy PAL/GAL devices

Procurement Notes

Verify the specific suffix 'A5N' against official Intel/Altera documentation to confirm it denotes the standard commercial/industrial grade variant within the MAX V family. Ensure compatibility with Quartus Prime software versions that support the MAX V device family for programming and configuration.

Selection Notes

Select this model when a single 1.8V supply is available and non-volatile configuration is required without external memory. Compare against the EPM1270 series if higher I/O counts or multiple voltage domains are necessary, noting that the EPM1270 supports 2.5V/3.3V supplies.

Part Context

The 5M1270ZT144A5N belongs to the Intel MAX V CPLD family, which succeeded earlier EPM/EPM7000 series devices. It offers lower power consumption and integrated Flash memory compared to previous generations, simplifying board design by eliminating the need for external configuration PROMs.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the MAX V family such as the 5M1270ZT144C5N, provided the temperature rating meets application requirements. Verify that any substitute maintains the same 1.8V core voltage and Flash-based configuration characteristics.
