XCR3512XL-12PQG208I

Overview

The XCR3512XL-12PQG208I is a CoolRunner-II CPLD manufactured by AMD (formerly Xilinx). It features 512 macrocells and supports up to 180 I/O pins within a 208-pin PQFP package. The device operates at a maximum clock frequency of 88 MHz with a typical pin-to-pin propagation delay of 12 ns. It utilizes a 3.3V supply voltage and incorporates non-volatile EEPROM technology for in-system programmability, allowing for repeated reconfiguration without removal from the circuit board.

Feature Summary

• 512 Macrocells with 12 ns propagation delay
• 180 I/O Pins in 208-PQFP Package
• In-System Programmable via JTAG
• 3.3V Operating Voltage

Applications

• Interface logic conversion
• Address/data bus buffering
• Clock driver and buffer applications

Procurement Notes

Verify the specific suffix '12' against official AMD datasheets to confirm the 12 ns speed grade variant. Confirm RoHS compliance status as older manufacturing runs may differ. Ensure the PQFP-208 package availability aligns with current production cycles, as legacy PLDs may have limited stock or end-of-life implications.

Selection Notes

Select this component when a moderate density of 512 macrocells is required for complex glue logic. The 12 ns speed grade suits general-purpose digital control tasks. Compare against the XCR3064XL series for lower density needs or the XCR3512XL-10 variant if faster 10 ns switching is necessary for higher frequency interfaces.

Part Context

This part belongs to the AMD CoolRunner-II family of Complex Programmable Logic Devices. This generation introduced EEPROM-based non-volatility, eliminating the need for external configuration memory chips often required by earlier Flash-based CPLDs. It serves as a drop-in replacement for many standard gate array applications.

Replacement Considerations

The XCR3512XL-10PQG208I offers identical functionality with a faster 10 ns delay specification. For higher density requirements, the XCR3512XL family provides options up to 12,000 system gates.
