XCR3512XL-12FTG256C

Overview

The XCR3512XL-12FTG256C is a Complex Programmable Logic Device (CPLD) belonging to the CoolRunner-XPLA3 family, manufactured by AMD. It features 512 macrocells and 12,000 system gates within two logic array blocks. The device supports up to 212 I/Os and operates on a single 2.7V to 3.6V supply voltage. It utilizes EEPROM technology for non-volatile storage, allowing for in-system programming with over 1,000 erase/program cycles. The maximum propagation delay is 7 ns, supporting operation frequencies up to 135 MHz across an industrial temperature range of -40°C to +85°C.

Feature Summary

• 512 Macrocells and 12,000 Gates: Provides substantial logic density within a compact architecture suitable for complex digital designs.
• High-Speed Performance: Achieves a maximum propagation delay of 7 ns and operating frequencies up to 135 MHz.
• EEPROM Non-Volatile Memory: Retains configuration data without power, eliminating the need for external configuration PROMs.
• Industrial Temperature Range: Rated for reliable operation from -40°C to +85°C, suitable for harsh environments.

Applications

• System Controller Logic
• Address Decoding
• Bus Bridging

Procurement Notes

This component is officially discontinued and no longer manufactured as per Product Discontinuation Notification dated January 1, 2024. Verification of availability should focus on surplus or new old stock channels rather than direct manufacturer distribution. Ensure that any sourced units are verified for authenticity and storage history due to the end-of-life status.

Selection Notes

When selecting this CPLD, verify that the FTG256 package (Fine-Pitch Ball Grid Array) fits the PCB footprint constraints. Confirm that the 2.7V to 3.6V VCC requirement aligns with the target system's power rails. For designs requiring higher performance or continued manufacturing support, consider migrating to newer CoolRunner-II or CoolRunner-IV families which offer improved speed and lower power consumption.

Part Context

The XCR3512XL is part of the CoolRunner-XPLA3 series, designed to bridge the gap between simple PALs/GALs and high-end FPGAs. It offers a cost-effective solution for moderate complexity logic applications. The 'XL' designation indicates extended temperature ranges and enhanced features compared to earlier generations. This specific model represents a high-density option within the series with 512 macrocells.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the EOL status. Potential alternatives include other AMD/Xilinx CPLDs with similar macrocell counts or Lattice Semiconductor devices like the MACHXO series. Verify electrical compatibility and timing requirements when substituting with components from different manufacturers.
