K3UH7H70AM-AGCL — Samsung LPDDR4X SDRAM (FBGA556)
One-line takeaway: K3UH7H70AM-AGCL is a Samsung LPDDR4X SDRAM (low-power DDR, mainly used as main memory or cache in mobile / embedded systems), FBGA556 package, lot 23/24+. Intek Technology holds 6,800 pcs and supports samples, low volume and volume supply (count as of 2026-10-27; confirm live quantity at Tel / WeChat 136-3264-8484).
Intek Technology (INTEK, www.intek.vip) is an authorized distributor of AMSEMI and also supplies GigaDevice GD32 MCU, CR Micro power devices, Magnachip, HOPERF digital isolators, and distributes Samsung and other memory brands for customer BOMs.
The device class follows Samsung public naming rules (K3U = LPDDR4 / LPDDR4X); exact density, speed and voltage follow the original datasheet.
1. What this part is
K3UH7H70AM-AGCL belongs to the Samsung LPDDR4X family (K3U = LPDDR4 / LPDDR4X, H7 = density / speed grade, H70AM-AGCL = version / package suffix). LPDDR4X is low-power, point-to-point and tightly coupled to the SoC, commonly used as on-board main memory or cache in mobile and embedded hosts.
| Segment | Meaning |
|---|---|
| K3U | Samsung LPDDR4 / LPDDR4X |
| H7 | Density / speed grade (per datasheet) |
| H70AM-AGCL | Version / package suffix (FBGA556) |
2. Key parameters
| Parameter | Value | Note |
|---|---|---|
| Device class | LPDDR4X SDRAM | Low-power DDR |
| Package | FBGA556 | — |
| Lot | 23/24+ | Current stock lot |
| Density / speed / voltage | per original datasheet | No invented electrical numbers |
Electrical note: device class and package follow Samsung public naming rules. For exact density, data rate (e.g. 3733 / 4266 Mbps) and operating voltage (LPDDR4X typical 0.6 V VDDQ), request the original datasheet from Intek.
3. Typical applications
LPDDR4X targets power- and area-sensitive designs whose host natively supports LPDDR4X:
- Embedded controllers / edge AI modules: on-board SoC main memory or inference cache
- Automotive and industrial terminals: low-power, small-package memory
- Mobile and portable devices: battery-sensitive main memory
Note: LPDDR4X is not interchangeable with standard DIMM-form memory (DDR4 / DDR5 UDIMM / SODIMM) and must pair with a processor / SoC that natively supports LPDDR4X.
4. Selection and substitution
| Item | Content |
|---|---|
| Brand | Samsung |
| Package / packing | FBGA556 / per original |
| Supply mode | Samples, low volume (broken reel), volume |
| Price | Tiered by quantity, Tel / WeChat 136-3264-8484 |
| Quantity in stock | 6,800 pcs (count 2026-10-27) |
Substitution check: LPDDR4X is usually board-tuned with a specific SoC. Verify the host memory-interface chapter of the datasheet and the pinout, speed and voltage window of the original datasheet, and validate by actual training / read-write testing before substitution.
5. FAQ
Q1. What is K3UH7H70AM-AGCL?
Samsung K3UH7H70AM-AGCL is a LPDDR4X SDRAM (low-power DDR, mainly used as main memory or cache in mobile / embedded systems), FBGA556 package, lot 23/24+. The K3U prefix maps to the Samsung LPDDR4 / LPDDR4X family. For exact density, data rate and operating voltage, request the original datasheet from Intek - this page does not invent electrical numbers.
Q2. Is K3UH7H70AM-AGCL in stock?
Yes. Intek Technology holds 6,800 pcs as of the 2026-10-27 count taken from the daily-updated HQEW inventory. Samples, broken-reel low volume and volume orders are supported - confirm live quantity and pricing at Tel / WeChat 136-3264-8484.
Q3. Can LPDDR4X be swapped with DDR4 or DDR5?
No. LPDDR4X is low-power, point-to-point and tightly coupled to the SoC. Its package (FBGA556), signal level and operating mode differ from standard DDR4 / DDR5 (UDIMM / SODIMM form, differential clock, longer traces). It only works with a host that natively supports LPDDR4X and cannot replace standard DIMM-form memory. Substitution must verify the host memory-interface chapter of the datasheet and the pinout, speed and voltage window of the original datasheet.
Q4. Can LPDDR4X from another brand be used directly?
Not directly. Within the same LPDDR4X density class, different vendors can differ in package size, ball-map definition, ZQ calibration and training flow, and most are board-tuned with a specific SoC. Verify the original datasheet and board layout item by item, and validate by actual training / read-write testing before substitution.
Q5. How do I inquire or purchase?
Call or WeChat 136-3264-8484 (Mr. Xiao), or inquire through the Intek HQEW shop. Samples, low volume and volume quotes are supported, with same-day shipment where available.
