H5TQ4G63CFR-RDC – DDR3 SDRAM – SK Hynix

The SK Hynix H5TQ4G63CFR-RDC is a 4Gb DDR3 SDRAM organized as 256M x 16, rated for DDR3-1866 operation at 1.5V in a 96-ball FBGA package. This is an obsolete, hard-to-find device available for RFQ.

The SK Hynix H5TQ4G63CFR-RDC is a 4-gigabit (4,294,967,296-bit) CMOS Double Data Rate III (DDR3) Synchronous DRAM. Organized as 256M x 16 across 8 internal banks, it is designed for applications requiring high memory density and high bandwidth. The device uses an 8-bit prefetch architecture with internally pipelined data paths and operates from a 1.5V supply, making it a common building block in embedded systems, networking gear, and legacy computing platforms.

The -RDC ordering suffix designates the DDR3-1866 speed grade (“RD” speed code) in the commercial temperature range. The component ships in a 96-ball Fine-pitch Ball Grid Array (FBGA) package suited to surface-mount assembly. This part is obsolete and has little to no authorized-distributor availability, which is why it is offered here on a request-for-quote basis.
