4Gb DDR3L-1600 x16 (256M x 16), CL11, 1.35 V, 96-ball FBGA – SK hynix C-revision die, no longer in volume production
The SK hynix H5TC4G63CFR-PBA is a 4Gb DDR3L SDRAM organized as 256M x 16 with 8 internal banks, rated DDR3L-1600 at CL11 with a 1.35 V supply (1.5 V compatible), in a 96-ball FBGA. The x16 4Gb density is the standard single-chip or two-chip memory in routers, set-top boxes, industrial controllers, printers and display boards still shipping in volume. SK hynix has moved production to later die revisions, so the C-revision part is sourced increasingly from channel and spot inventory by OEMs that want to avoid requalifying their DDR3 controller settings. Cerametronics sources H5TC4G63CFR-PBA and compatible later revisions with full lot traceability and quotes within 24 hours.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Why is H5TC4G63CFR-PBA hard to source?
DDR3 is a legacy interface and SK hynix has moved its 4Gb x16 production to newer die revisions, so the C-revision part is no longer produced in volume. Networking, industrial and consumer boards whose memory controllers were tuned on the CFR die keep buying remaining stock rather than requalifying.
Are newer SK hynix 4Gb x16 DDR3L parts compatible?
Later revisions such as H5TC4G63EFR-PBA share the same 96-ball footprint and DDR3L-1600 timing, and many designs can switch after a DDR calibration check. We can quote the original CFR revision or a later revision depending on your qualification requirements.
