H5TC4G63EFR-RDA – DDR3L SDRAM – SK Hynix

The SK Hynix H5TC4G63EFR-RDA is a 4Gb DDR3L SDRAM organized as 256M x 16, housed in a 96-ball FBGA package and operating at 1.35V with a DDR3-1866 (-RD) speed grade. An obsolete/hard-to-find memory device available for RFQ.

The SK Hynix H5TC4G63EFR-RDA is a 4-gigabit low-power Double Data Rate III (DDR3L) Synchronous DRAM organized as 256M x 16. Designed for main-memory applications that demand large density, high bandwidth, and low-power operation, it runs at a 1.35V VDD/VDDQ supply while remaining backward compatible with 1.5V DDR3 environments without changes. The device delivers fully synchronous operation, an 8-bit prefetch architecture, and eight internal banks, and is supplied in a JEDEC-standard 96-ball FBGA package. It is Lead-Free and Halogen-Free (RoHS compliant).

Key Features

• Density: 4Gb (4 Gigabit)

• Programmable CAS latency 5, 6, 7, 8, 9, 10, 11 and 13; programmable CAS Write Latency (CWL) 5-8; additive latency 0, CL-1, CL-2
• Fully differential clock inputs (CK, CK#) and differential data strobe (DQS, DQS#)
• On-chip DLL, Dynamic On-Die Termination, ZQ calibration, write leveling, asynchronous RESET
• Temperature: Commercial 0°C ~ 95°C (suffix "A"), Normal power consumption
• Package: 96-ball FBGA; Lead-Free & Halogen-Free (RoHS compliant)

Applications

• Embedded and industrial computing main memory
• Networking and telecom line cards
• Set-top boxes, digital signage, and consumer electronics
• Single-board computers and SoC reference designs
• Legacy system repair, refurbishment, and end-of-life production builds

Why Source H5TC4G63EFR-RDA from Pacific Component Xchange

The H5TC4G63EFR-RDA is an obsolete, hard-to-find DDR3L memory device with little to no authorized-distributor availability.
