H5TC4G63EFR-RDI – DDR3L SDRAM – SK Hynix

The SK Hynix H5TC4G63EFR-RDI is a 4Gb low-power DDR3L SDRAM organized as 256M x 16, operating at 1.35V in a 96-ball FBGA package and rated for the industrial temperature range (-40°C to +95°C).

The SK Hynix H5TC4G63EFR-RDI is a 4-gigabit low-power DDR3L Synchronous DRAM from SK Hynix’s H5TC4G63EFR family. Organized as 256M x 16, it operates at a 1.35V supply (V_DD = V_DDQ = 1.35V) while remaining backward compatible with 1.5V DDR3 environments, making it well suited to embedded, networking, and industrial main-memory designs that demand high bandwidth and reduced power. The “-RD” speed code rates the device up to DDR3-1866 (13-13-13), and the trailing “I” denotes the industrial temperature range (-40°C to +95°C).
