H58G56AK6QX032 概要
LPDDR5 (Low Power Double Data Rate 5) is the fifth generation of the JEDEC LPDDR SDRAM family, designed for mobile, edge computing, and automotive systems where bandwidth-per-watt matters more than raw capacity per rank. Within the memory hierarchy it sits as the main system DRAM, sitting between high-speed caches and long-term NAND flash storage, and it is the dominant main-memory standard for SoC-based platforms including ADAS domain controllers and infotainment head units.
Key features of the H58G56AK6QX032 include the 6400 Mbps pin speed (LPDDR5-6400), a x64 organization providing 51.2 GB/s peak bandwidth per device, an automotive qualification level suited to extended temperature environments, and the low-voltage signaling of LPDDR5 (0.5V VDDQ) that significantly reduces I/O power compared with LPDDR4X. The FBGA-315 ball-grid array provides reliable solder-joint performance under vibration and thermal cycling typical of automotive deployments.
Technically, LPDDR5 introduces bank-group-aware architectures, 16-bank operation, and enhanced DVFS (dynamic voltage frequency scaling) of the core rail, allowing the memory controller to trade speed against power in real time. SK Hynix fabricates this device on an advanced DRAM process with on-die termination and DFE (decision feedback equalization) receivers to sustain 6400 Mbps signaling integrity across the channel.
Typical applications include ADAS/autonomous-driving domain controllers, automotive infotainment and digital cockpit SoCs, telematics and gateway modules, and high-performance edge computing platforms requiring certified automotive memory. The x64 bus width makes it a natural fit alongside mid-range SoCs such as the Intel/Altera Agilex-family co-processors and automotive SoCs with 64-bit LPDDR5 interfaces.
When designing with this device, validate the memory controller's LPDDR5 speed-grade support, keep trace lengths length-matched to the fly-by/command-address topology, and confirm the 3-rail power sequencing (VDD2 1.8V, VDD 1.05V, VDDQ 0.5V) in your PMIC selection.

主な用途
H58G56AK6QX032 の用途: 6 件s: ADAS Domain Controller, Automotive Digital Cockpit / Infotainment, Telematics and Gateway Modules, Edge Computing and AI Accelerator Modules, Industrial Controllers and Robotics, Data Storage and Embedded Logging Systems.
ADAS Domain Controller
The H58G56AK6QX032 fits ADAS domain controllers because its LPDDR5-6400 interface delivers 51.2 GB/s per device in a x64 configuration, enough to feed multi-camera sensor fusion and neural-inference SoCs in real time. The automotive qualification grade targets the extended temperature and reliability envelope required in front-view and surround-view ECU deployments. In the memory subsystem it connects to the SoC's 64-bit LPDDR5 controller through length-matched fly-by routing; the 0.5V VDDQ rail keeps I/O power low, which matters for passively cooled windshield-mounted housings. Designers should budget IDD current on the 1.05V core rail and verify controller training at 6400 Mbps across the full temperature range before releasing the design.
おすすめ
Automotive Digital Cockpit / Infotainment
Digital cockpit SoCs driving multiple high-resolution displays benefit directly from the H58G56AK6QX032's 6400 Mbps data rate and 51.2 GB/s peak bandwidth, which sustain 3D navigation rendering, cluster graphics, and video decode simultaneously. SK Hynix's own product overview lists computing modules and embedded logging among target uses, and infotainment head units are a canonical automotive LPDDR5 deployment. The FBGA-315 package withstands the thermal cycling of dashboard environments, and the 1.8V/1.05V/0.5V triple-rail scheme integrates with common automotive PMICs. Place the DRAM within the controller's supported trace-length budget and use on-die termination settings from the datasheet to maintain signal integrity at full speed.
おすすめ
Telematics and Gateway Modules
Connected vehicle gateways aggregate CAN, Ethernet, and cellular traffic while running firewall and OTA-update stacks, workloads that need responsive main memory more than extreme bandwidth. The H58G56AK6QX032 serves this role with 4 GB of automotive LPDDR5, providing headroom for secure-boot log storage, message buffering, and hypervisor-hosted services. LPDDR5's DVFS capability allows the gateway SoC to drop the memory frequency - and core voltage - during idle periods, cutting average power in always-on modules that must remain powered with the vehicle parked. The automotive grade supports the under-hood-adjacent and engine-bay temperature zones many gateways occupy, and the FBGA-315 ballout survives vibration per automotive mechanical expectations.
おすすめ
Edge Computing and AI Accelerator Modules
Edge AI modules running vision or speech inference models need memory bandwidth to stream activation tensors between the accelerator and DRAM; the H58G56AK6QX032's 51.2 GB/s per-device bandwidth at 6400 Mbps directly raises achievable inference throughput versus LPDDR4X-class alternatives. SK Hynix positions the part for computing modules and embedded logging, and x64 organization pairs cleanly with 64-bit memory controllers on common edge-SoC platforms. Because LPDDR5 channels support per-bank refresh and deeper bank groups, real-world bandwidth efficiency at high utilization is superior to prior generations, reducing the DRAM count needed for a given model size. Verify the module's PMIC supplies the exact 0.5V VDDQ tolerance window at full 6400 Mbps operation.
おすすめ
Industrial Controllers and Robotics
Industrial PCs, motion controllers, and robot main controllers deploy LPDDR5 for the same reasons as automotive platforms: high bandwidth, low I/O power, and BGA mechanical robustness under continuous vibration. The H58G56AK6QX032's 32Gb capacity comfortably hosts Linux-based control stacks plus logging buffers for predictive maintenance, and its 6400 Mbps rate keeps deterministic control loops responsive when vision or FFT workloads run concurrently. GlobalSpec's overview explicitly lists industrial controllers among the target uses for this part. In factory environments, designers should validate operation at the controller's lower speed bins as a fallback strategy, since LPDDR5 DVFS allows graceful derating under EMI-heavy conditions rather than hard failure.
おすすめ
Data Storage and Embedded Logging Systems
Event data recorders, fleet dashcams, and embedded logging appliances write continuous high-rate sensor streams to storage, and the H58G56AK6QX032 acts as the write-buffer between sensors and NAND. Its 51.2 GB/s peak bandwidth absorbs burst captures from multiple image sensors simultaneously, while 4 GB of capacity provides seconds of buffering that absorbs NAND erase-cycle latency spikes without frame loss. The SK Hynix automotive product overview names embedded logging and data storage among its intended functions. The LPDDR5 interface's low 0.5V VDDQ signaling limits buffer power in passively cooled recorder housings, and automotive qualification supports installations in the dashcam and EDR duty cycles that approach continuous operation.

設計ノート
The H58G56AK6QX032 requires three rails: VDD2 at 1.8V, VDD at 1.05V, and VDDQ at 0.5V (per distributor specification: 1.8V / 1.05V / 0.5V). Choose an automotive PMIC that outputs all three rails with the sequencing and DVFS support the SK Hynix datasheet requires; LPDDR5 core voltage scales dynamically with frequency, so a PMIC with I2C/SVDT feedback to the memory controller is strongly recommended. Budget IDD current on the 1.05V rail at full 6400 Mbps operation and verify the 0.5V VDDQ tolerance window with an oscilloscope at the ball side, not just at the regulator output.
At 6400 Mbps, signal integrity dominates the layout. Route the CA bus and DQ byte lanes as length-matched groups per the SK Hynix LPDDR5 layout guidelines, keep stubs off DQS differential pairs, and reference DQ/CA routing to a continuous ground plane. Use ODT and training values from the memory controller's LPDDR5-6400 configuration and re-run write leveling/read training across the full temperature range in validation. Vias-in-pad under the FBGA-315 ballout reduce escape complexity; if dog-bone escape is used, verify eye diagrams on the longest byte lane.
Do not substitute grade suffixes blindly: QX, JX, and PX variants of the H58G56AK6 family share the FBGA-315 pinout but differ in speed/temperature binning, and an automotive design released with a P-grade part instead of the QX automotive grade may fail qualification. Also confirm the memory controller supports LPDDR5 (not just LPDDR4X) and the specific 6400 Mbps speed grade before layout lock, since LPDDR5 CA bus training and bank-group behavior differ fundamentally from LPDDR4.
