EPM1270GF256C3

Complex Programmable Logic Devices Overview

The EPM1270GF256C3 is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family, manufactured by Altera. It features 980 macrocells and supports 212 I/O lines within a 256-pin FBGA package measuring 17x17 mm. The device operates at a supply voltage of 1.8 V, with a maximum operating frequency of 304 MHz and a propagation delay of 6.2 ns. It utilizes Flash memory technology for non-volatile configuration and supports system-in-programmability via JTAG. The component is rated for commercial temperature ranges up to +70 °C.

Complex Programmable Logic Devices Feature Summary

• Contains 980 macrocells and 127 logic array blocks (LABs) for high-density logic implementation.
• Supports In-System Programming (ISP) and JTAG boundary scan testing.
• Utilizes Flash-based non-volatile memory architecture for instant-on functionality.
• Operates at 1.8 V core voltage with support for 3.3 V I/O interfaces.

Complex Programmable Logic Devices Applications

• High-speed data interface bridging between different voltage domains.
• Address decoding and bus buffering in embedded systems.
• State machine control for industrial automation equipment.
• Configuration management for peripheral devices requiring low power consumption.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C3' against official Intel/Altera documentation to confirm the commercial temperature grade (+70 °C) and lead-free status. Ensure compatibility with 1.8 V core requirements if replacing older variants. Check for RoHS compliance status as some listings indicate non-compliance for certain revisions. Confirm package dimensions match the 256-FBGA (17x17 mm) specification before integration.

Complex Programmable Logic Devices Selection Notes

Select this model when a non-volatile CPLD with ISP capability is required for designs needing 980+ macrocells. The 1.8 V operation makes it suitable for battery-powered or low-power applications compared to 3.3 V families. Ensure the design footprint accommodates the 256-ball FBGA package. Verify that the 304 MHz maximum frequency meets the timing constraints of the target application.

Complex Programmable Logic Devices Part Context

This component is part of the MAX II family, which bridges the gap between simple PLDs and complex FPGAs. It offers the simplicity of CPLDs with the flexibility of Flash-based reprogramming. The EPM1270 variant provides a mid-range density option within the series, balancing pin count and logic resources for general-purpose programmable logic tasks.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other MAX II devices with similar macrocell counts, such as the EPM1270F256 series. Verify pin-to-pin compatibility and voltage levels when considering alternatives from the same family. Cross-reference with Intel's official obsolescence notices to ensure long-term availability.
