XC9572XL-10PC44C

Complex Programmable Logic Devices Overview

The AMD XC9572XL-10PC44C is a Complex Programmable Logic Device (CPLD) from the XC9500XL family, manufactured by AMD. It features 72 macrocells and 1,600 usable gates organized into four Logic Array Blocks (LABs). The device operates at a supply voltage of 3V to 3.6V with a maximum propagation delay of 10 ns and a system frequency up to 178 MHz. It utilizes Flash memory technology for non-volatile storage and supports System-In-Programmability (SIP) via JTAG. The component is housed in a 44-pin PLCC package and is rated for an operating temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, which succeeded the original XC9500 family. The XC9572XL variant specifically provides 72 macrocells. The '10' suffix indicates the 10 ns speed grade, while 'PC44' denotes the 44-pin PLCC package. This series is characterized by its low power consumption and fast programming capabilities compared to earlier EPROM-based CPLDs.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed direct substitutes include the XC9572XL-10VQ44C (VQFP package) and XC9572XL-10PCG44C (Pb-free PLCC package). Cross-vendor alternatives such as Microchip's ATF1504ASV series or Lattice's LC4000 series may be considered but require verification of pin compatibility and logic density.
