What is XC18V04VQ44C? It is a Xilinx XC18V00-series in-system-programmable configuration PROM with 4,194,304 configuration bits. DS026 specifies a 3.3 V internal supply, IEEE 1149.1 JTAG boundary scan and in-system programming, serial configuration up to 33 MHz, parallel output up to 264 Mb/s at 33 MHz, and 20,000 program/erase cycles. Multiple XC18V00 PROMs can be cascaded when one FPGA bitstream or a chain of FPGAs requires more configuration storage.
What do VQ44C and lifecycle mean? The current device data sheet defines VQ44 as a 44-pin plastic quad flat package and explicitly defines the C ordering suffix as the industrial -40°C to +85°C ambient range. This device-specific ordering rule is the applicable temperature definition for the exact part. AMD/Xilinx notice XCN20013 covers all XC18V00 products under a phased discontinuation program and lists no direct compatible replacement for XC18V04VQ44C. ZZX Electronics lists 1,860 pcs with date code 1646. Before acceptance, verify the exact top marking and die revision, programmed image and security state, package leads, lot/date-code evidence, storage history and compatibility with the intended programming cable and legacy Xilinx software flow. Send an RFQ for current lot photos, traceability and programming-state confirmation.
