XCR3064XL-10PC44C

Overview

The XCR3064XL-10PC44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XPLA3 series. It features 64 macrocells and 36 I/O lines housed in a 44-pin Plastic Quad Flatpack (PQCC44/LCC-44) package. The device operates on EEPROM storage technology with a maximum propagation delay of 10 ns, supporting a maximum clock frequency of 95 MHz. It functions within a supply voltage range of 3 V to 3.6 V and an operating temperature range of 0°C to +70°C.

Feature Summary

• 64 Macrocells with 36 I/Os in a 44-pin PQCC44 package
• 10 ns maximum propagation delay and 95 MHz max clock frequency
• EEPROM non-volatile memory technology for configuration retention

Applications

• General-purpose digital logic control systems
• Address decoding and bus bridging applications
• Interface translation between different voltage domains

Part Context

This component belongs to the XPLA3 family of CPLDs, designed as a successor to earlier GAL-based solutions. It offers higher density and speed compared to standard PAL/GAL devices while maintaining pin compatibility with legacy designs. The XCR3064XL variant specifically provides 64 macrocells, balancing complexity and cost for mid-range logic applications.

Replacement Considerations

Direct pin-compatible replacements within the same package include the XCR3064XL-7PC44C, which offers faster performance (7 ns delay). Designers should verify timing constraints when substituting faster variants, as the original design may not require the higher speed.
