H5TQ4G83EFR-RDC – DDR3 SDRAM – SK Hynix

The H5TQ4G83EFR-RDC is an SK Hynix 4Gb DDR3 SDRAM device organized as 512M x 8 in a 78-ball FBGA package, operating at 1.5V with a DDR3-1866 speed grade. This part is hard-to-find and available for RFQ at Pacific Component Xchange.

The H5TQ4G83EFR-RDC from SK Hynix is a 4-gigabit (4Gb) DDR3 Synchronous DRAM (SDRAM) component designed for high-bandwidth main-memory applications. It is organized as 512M x 8 (x8 data width) and packaged in a space-efficient 78-ball Fine-pitch Ball Grid Array (FBGA-78). The device operates from a nominal 1.5V supply (VDD/VDDQ, 1.5V ± 0.075V) and belongs to SK Hynix’s 4Gb DDR3 SDRAM family. The “-RDC” suffix denotes the DDR3-1866 speed grade at commercial temperature.

DDR3 SDRAM transfers data on both the rising and falling edges of the clock and uses an 8-bit prefetch architecture to deliver high effective bandwidth. The H5TQ4G83EFR-RDC supports the standard DDR3 feature set, including programmable CAS latency, programmable burst length (BL8 / BC4), dynamic on-die termination (ODT), write leveling, and ZQ calibration.
