H5TQ4G63EFR-RDI – DDR3 SDRAM – SK Hynix

The H5TQ4G63EFR-RDI is an SK Hynix 4Gb DDR3 SDRAM organized as 256M x 16, rated for DDR3-1866 (1866 MT/s) operation at 1.5V in a 96-ball FBGA package. This is an obsolete, hard-to-find industrial temperature-grade memory device available for RFQ.

The H5TQ4G63EFR-RDI from SK Hynix is a 4-gigabit (4Gb) DDR3 Synchronous DRAM organized as 256M x 16. Packaged in a space-efficient 96-ball Fine-pitch Ball Grid Array (FBGA), it is designed for high-bandwidth main-memory and embedded applications where a x16 data width simplifies board layout. The “-RD” speed code designates DDR3-1866 (1866 MT/s) operation, and the trailing “I” identifies this as the industrial temperature-grade variant. The device operates at 1.5V (the “H5TQ” prefix denotes the 1.5V DDR3 family) and is offered as a Lead-Free & Halogen-Free, RoHS-compliant part.
