AMD XC2C64A-7QFG48C

Overview

XC2C64A-7QFG48C from AMD is a CoolRunner-II CPLD intended for low-power programmable logic, interface adaptation, control sequencing, and moderate-density board-support logic in embedded and communications hardware. The device combines 64 macrocells, very low standby-current architecture, fast CPLD timing, and multi-voltage I/O support in a 48-VFQFN exposed-pad package package for denser programmable control tasks than the smaller 32-macrocell class.

The CoolRunner-II CPLD series provides nonvolatile logic retention, JTAG-based in-system programmability, low-power architecture, and scalable macrocell resources for compact control and interface functions. For engineers reviewing the XC2C64A-7QFG48C datasheet, XC2C64A-7QFG48C pinout, XC2C64A-7QFG48C application, or XC2C64A-7QFG48C equivalent, this device is widely used in control-plane logic, protocol adaptation, industrial modules, communications boards, bus interfacing, and low-power programmable board-support designs.

Technical Context

In embedded systems, XC2C64A-7QFG48C serves as a compact CPLD for moderate-complexity deterministic logic tasks such as state sequencing, bus adaptation, address/control decoding, and local supervisory logic. The 64-macrocell resource level makes it a practical fit when the logic demand exceeds the smallest CPLD devices but still does not justify a larger FPGA platform.

CoolRunner-II devices are especially useful when standby current matters, because the family is designed for low-power always-on logic roles. The architecture also supports mixed-voltage I/O interfacing, which helps one CPLD participate across several board-level digital domains.

XC2C64A-7QFG48C is commonly used when a board needs compact programmable logic with more logic headroom than 32-macrocell devices while keeping low-power CPLD behavior, JTAG updateability, and deterministic interface timing.

Key Specifications

Pinout & Package

The XC2C64A-7QFG48C pinout includes programmable I/O, clock-capable pins, JTAG interface pins, supply rails, and ground returns in the 48-VFQFN exposed-pad package outline.

For PCB design, I/O-bank planning, JTAG access, and supply decoupling remain important because CoolRunner-II CPLDs are often used between multiple logic domains and in always-on board-support roles.

Key Features

• 64 macrocells provide more headroom than the smallest CoolRunner-II devices.
• Very low standby current suits always-on and portable logic functions.
• Nonvolatile CPLD operation preserves logic at power cycle.
• JTAG in-system programmability supports production and field updates.
• Mixed-voltage I/O support eases logic-domain bridging.
• Multiple package options fit dense embedded layouts.

Applications

Equivalent & Alternatives

When evaluating a XC2C64A-7QFG48C equivalent, engineers should compare macrocell count, package, low-power behavior, timing grade, and logic-domain compatibility.

Compared with XC2C64A-7VQG44C, XC2C64A-7QFG48C selection depends mainly on package and board-fit details while staying in the same CoolRunner-II family. XC2C64A-7QFG48C vs XC9572XL-10VQG44C selection depends on whether the design should prioritize CoolRunner-II low-power behavior or maintain XC9500XL architectural continuity.
