Q6422XM3BDGVK-U

The Q6422XM3BDGVK-U is a 64 Gbit Low Power DRAM (LPDDR4X) device in a 200-ball FBGA package from Kingston Technology. It implements a parallel LPDDR4X architecture with two channels (2048M × 16 I/O × 2 channels) to deliver high-bandwidth, double-data-rate memory for mobile and compact system designs.

Designed for low-voltage operation and high data throughput, the device targets mobile and handheld applications requiring fast, energy-efficient DRAM. Key value comes from its 4266 Mb/s maximum data rate, programmable timing and driver options, and advanced refresh/power-saving features.

Key Features

• Memory Architecture and Capacity — 64 Gbit total capacity organized as 2048M × 16 I/O × 2 channels (2 ranks), providing 4G × 16 logical organization and eight internal banks per channel.
• High Data Rate — Clock rate 2133 MHz (2.133 GHz) with a maximum data rate of 4266 Mb/s per pin and double-data-rate transfers.
• Low-Power Supply Options — Multiple supply domains: VDD1 = 1.70–1.95 V, VDD2 = 1.06–1.17 V and VDDQ = 0.57–0.65 V, enabling low-power operation typical of LPDDR4X devices.
• Programmable Timing and Drivers — Programmable read and write latencies (RL/WL) and selectable driver strength for system tuning.
• Burst and Transfer Modes — Supports burst lengths of 16, 32 and on-the-fly burst mode (enabled by MRS) with auto-precharge options.
• Refresh and Power Management — Auto-refresh, self-refresh, per-bank refresh, Partial Array Self-Refresh (PASR), and Auto Temperature Compensated Self-Refresh (ATCSR) using a built-in temperature sensor; 8192 refresh cycles per 32 ms.
• Signal Interfaces — Differential clock inputs (CK_t/CK_c) and bi-directional differential data strobe (DQS_t/DQS_c); commands and data referenced to both clock/DQS edges. DMI pin support for write data masking and DBI/DC functionality.
• Package and Thermal — 200-ball FBGA (200-VFBGA / 200-FBGA 10 × 14.5 mm) with operating temperature range TC = −25 °C to +85 °C.
• Performance Timing — Access time ~3.5 ns and write cycle time (word page) 18 ns.

Typical Applications

• Mobile and Handheld Devices — High-bandwidth LPDDR4X memory for mobile computing and handheld systems requiring energy-efficient DRAM.
• Embedded Systems — Parallel LPDDR4X interface and programmable latencies suitable for embedded designs that need configurable memory performance.
• Consumer Electronics — Memory capacity and throughput for consumer devices that leverage low-voltage, high-speed DRAM.

Unique Advantages

• High Throughput: 4266 Mb/s maximum data rate and 2133 MHz clock enable high-bandwidth data transfers for performance-sensitive workloads.
• Low-Voltage Operation: Multiple supply domains including VDD2 ≈1.06–1.17 V and VDDQ ≈0.57–0.65 V reduce power draw in portable applications.
• Flexible Timing and Drive Control: Programmable RL/WL and driver strength let designers tune latency and signal integrity for specific system needs.
• Advanced Power Management: PASR, per-bank refresh, ATCSR and self-refresh options minimize refresh overhead and extend low-power operation windows.
• Compact FBGA Package: 200-ball FBGA (10 × 14.5 mm supplier package) balances density and mounting for compact system boards.
• Robust Thermal Range: Specified operation from −25 °C to +85 °C for a wide set of ambient conditions.
