What is the Samsung K4U6E3S4AB-KHCL?

It is a Samsung 16 Gb (2 GB) LPDDR4X low-power mobile SDRAM with a x32 organization, a 4266 Mbps data rate, and a 200-ball FBGA package. The -KHCL variant supports an extended -40 to 105 u00b0C operating temperature range.

Is the K4U6E3S4AB-KHCL still in production?

No. Samsung has discontinued its LPDDR4X product line, including this part. It is now an obsolete, hard-to-find memory device, which is why it is offered through Pacific Component Xchange on a request-for-quote basis.

What is the difference between the KHCL and MGCL variants?

The K4U6E3S4AB-KHCL carries an extended operating temperature range of -40 to 105 u00b0C, suited to automotive and industrial use, whereas commercial-grade variants such as the MGCL target a narrower temperature range. Density (16 Gb), organization (x32), speed (4266 Mbps), and package (200-ball FBGA) are otherwise the same.

What is the operating voltage of the K4U6E3S4AB-KHCL?

It uses the standard LPDDR4X rail configuration: VDD1 at 1.8 V, VDD2 at 1.1 V, and VDDQ at 0.6 V for low-power operation.

How do I get pricing and lead time for the K4U6E3S4AB-KHCL?

Submit a Request for Quote (RFQ) to Pacific Component Xchange. Because this is an obsolete part with limited authorized availability, our team will confirm current stock, pricing, and lead time for your required quantity.

Does Pacific Component Xchange verify authenticity of obsolete memory?

Yes. Every order is subject to authenticity verification and inspection to guard against counterfeit or out-of-spec components, which is especially important for end-of-life and hard-to-find memory like this part.
