K4U6E3S4AB-MGCL

K4U6E3S4AB-MGCL is a 16Gb LPDDR4X Mono mobile SDRAM from Samsung. The datasheet identifies the array on the §2.0 key-feature line as “16G = 64M x16DQ x8banks x2channels” and on the cover as 64Mb x16DQ x8banks x2channels. The device is rated up to 4266 Mbps at tCK = 0.468 ns on the LVSTLE_06 interface with VDD1/VDD2/VDDQ = 1.8V/1.1V/0.6V, in the package printed on the cover as 200FBGA, 10×15, with case temperature Tc = -25 to +85 °C. Procurement note: the full order code printed on the §3.0 ordering table is K4U6E3S4AB-MGCL — bills of material, purchase orders and silkscreen should carry that code.

Key figures

• Density and organisation: 16Gb LPDDR4X in a Mono configuration; §2.0 prints “16G = 64M x16DQ x8banks x2channels” and the cover prints 64Mb x16DQ x8banks x2channels.
• Data rate: up to 4266 Mbps at tCK = 0.468 ns; the §3.0 note states that “4266Mbps is backward compatible to lower frequency.
• Channel structure: the §2.0 feature list prints 2channel composition per die and 8 internal banks for each channel; the ordering table gives the Org column as 2Ch, x16/Ch, and the decode strip gives 3S = x32 (Mono LPDDR4X) and 4 = 8Bank.
• Supplies and IO: LVSTLE_06 with VDD1/VDD2/VDDQ = 1.8V/1.1V/0.6V.
• Package: 200-ball FBGA, 10 x 15 mm — the decode strip gives M = 200-FBGA.
• Refresh: the §2.0 feature list prints Refresh rate : 3.9us, and the density field of the decode strip gives 6E = 16G, 8K/32ms.
• Device generation: the decode strip marks B = 3rd Generation.

Ordering and decoding

§3.0 prints exactly one order code for this document, K4U6E3S4AB-MGCL. Its decode strip reads: device type LPDDR4X SDRAM, 6E = 16G, 8K/32ms, 3S = x32 (Mono LPDDR4X), 4 = 8Bank, the interface field gives LVSTLE_06 at 1.8V/1.1V/0.6V, M = 200-FBGA and G gives the temperature window quoted below.

Temperature rating

The §3.0 order table prints the rating as Tc = -25 ~ 85 and the decode strip repeats that window. The datasheet carries no reliability qualification standard and no grade certification of any kind, so this page asserts none: the temperature window is published exactly as printed, nothing more.

Lifecycle status

The Lifecycle row above is left blank: this document is a technical specification and states no product-status or end-of-life figure, so we publish none.

Provenance

Every figure above is taken from the Samsung datasheet for K4U6E3S4AB-MGCL dated Rev. 1.0, Jul. 2021, whose revision history ends at “Final datasheet”. The copy is a channel-held local file and has not been byte-compared with a copy downloaded from the manufacturer, so the manufacturer datasheet button is left unpopulated and no direct PDF link is published.
