XCR3064XL-7PC44C

Overview

The XCR3064XL-7PC44C is a Complex Programmable Logic Device (CPLD) belonging to the XPLA3 series, manufactured by AMD/Xilinx. It features an EEPROM storage type and operates within a supply voltage range of 3 V to 3.6 V. The device contains 64 macrocells, 1500 gates, and provides 36 I/O lines across two logic array blocks. Packaged in a PLCC-44 surface-mount format, it supports a maximum operating frequency of 192 MHz with a typical propagation delay of 5.5 ns. The component functions reliably within an ambient temperature range of 0°C to +70°C.

Feature Summary

• XPLA3 architecture with 64 macrocells and 1500 system gates
• EEPROM non-volatile memory technology for configuration retention
• High-speed performance with 5.5 ns max propagation delay and 192 MHz clock capability
• 36 I/O pins available in a compact PLCC-44 package

Applications

• General-purpose digital logic implementation
• Address decoding and bus interfacing
• State machine control in embedded systems
• Signal protocol conversion between different voltage domains

Procurement Notes

Verify manufacturer authenticity as multiple entities, including Rochester Electronics, distribute this part number. Confirm the specific suffix '7' corresponds to the 7 ns speed grade and 'PC44' indicates the plastic quad leaded chip carrier package. Check RoHS compliance status and current availability, as distribution channels may list varying stock levels or obsolescence notices.

Selection Notes

Select this component when a moderate density CPLD with EEPROM reprogrammability is required. Ensure the design fits within the 64 macrocell limit and utilizes no more than 36 I/Os. Verify that the 3V to 3.6V power supply aligns with the target system's voltage rails. Consider the PLCC-44 footprint constraints during PCB layout planning.

Part Context

This device is part of the Xilinx XPLA3 family, designed to replace older GALs and PALs with higher density and flexibility. The XCR3064XL variant specifically offers enhanced performance over previous generations while maintaining compatibility with standard JEDEC pinouts for legacy designs.

Replacement Considerations

Direct pin-compatible replacements include other speed grades within the same package, such as the XCR3064XL-10PC44C, which offers a slower 10 ns delay but identical physical dimensions and functionality.
