MT40A512M16HA-083E Overview
DDR4 SDRAM, or Double Data Rate 4 Synchronous Dynamic Random-Access Memory, is volatile memory that transfers data on both edges of the clock. It belongs to the SDRAM and DRAM hierarchies and operates from a lower core voltage than DDR3 while supporting higher data throughput. DDR4 memory is widely used in servers, networking equipment, data storage systems, and industrial computing platforms.
The MT40A512M16HA-083E provides an 8Gbit density with a 16-bit parallel data bus. Its 1.2V VDD and VDDQ supply, 2.5V VPP supply, 1.2V pseudo open-drain I/O interface, and internal adjustable VREFDQ generation support modern DDR4 signal-integrity requirements. Micron specifies a 1.2V supply tolerance of plus or minus 60mV and VPP tolerances from -125mV to +250mV.
Refresh timing is temperature dependent. The device uses an 8192-cycle refresh interval, with stated refresh times of 64 ms from -40 degrees C to 85 degrees C, 32 ms above 85 degrees C to 95 degrees C, and 16 ms above 95 degrees C. The 96-ball FBGA uses a 0.8 mm ball pitch and is intended for surface-mount assembly.
Typical applications include high-performance servers, routers, switches, storage systems, and industrial platforms. The x16 organization enables practical memory-controller configurations where wider logical channels can be built from multiple devices.
PCB implementation should follow Micron's DDR4 layout guidance, including controlled-impedance routing, careful fly-by topology, and placement of decoupling and command/address termination networks close to the memory device. A stable, low-noise 1.2V rail and a compliant 2.5V VPP supply are essential.
This page combines manufacturer specifications, distributor references, replacement analysis, and practical DDR4 design guidance to support component selection and board-level implementation.

Typical Applications
MT40A512M16HA-083E is suitable for 6 applications: High-Performance Server Memory, Networking Equipment, Industrial Computing Platforms, Data Storage Systems, Telecommunications Equipment, Embedded Control Systems.
High-Performance Server Memory
The MT40A512M16HA-083E is suitable for server memory channels that require an 8Gbit DDR4 device with a 512M x 16 organization and up to DDR4-2400-class signaling. Its 1.2V core and I/O supply lowers the power burden compared with older memory technologies while providing sufficient bandwidth for processor and accelerator traffic. A controller with compatible x16 DDR4 support can use the device in server DIMM or module designs when thermal and signal-integrity requirements are met. The board must follow Micron's recommended topology, decoupling, VPP generation, and controlled-impedance routing.
Recommended
Networking Equipment
The MT40A512M16HA-083E can support packet-processing and switching platforms that need deterministic DDR4 bandwidth in a compact 96-ball FBGA package. Its 512M x 16 organization allows memory designers to construct wider channels from multiple devices, while the 1.2V pseudo open-drain interface and internal VREFDQ generation support DDR4 signal integrity. In routers and switches, placement near the memory controller, careful fly-by routing, and clean 1.2V and 2.5V supplies are essential. Exact controller and thermal requirements must be verified for each platform.
Recommended
Industrial Computing Platforms
The MT40A512M16HA-083E is appropriate for industrial controllers and embedded systems that need local DDR4 memory for buffering, networking, or compute workloads. Its 8Gbit density and 16-bit organization provide a practical balance of capacity, bandwidth, and package size for control cabinets, machine vision, and industrial gateways. Temperature-grade qualification, refresh timing, and controller support must match the enclosure environment. Since the supplied data does not state the complete operating-temperature range, engineers should confirm the exact ordering option before production release.
Recommended
Data Storage Systems
The MT40A512M16HA-083E can serve as working memory in storage controllers, caching systems, and embedded storage platforms where sustained DDR4 throughput is needed. Its 512M x 16 organization can simplify the construction of memory channels that support storage controllers, while 1.2V operation helps constrain power in compact systems. Storage designs should account for refresh behavior, controller training support, VPP supply quality, and the thermal environment around the FBGA. Validate the exact Micron ordering suffix and memory-controller compatibility during design-in.
Recommended
Telecommunications Equipment
The MT40A512M16HA-083E is suitable for telecommunications infrastructure requiring DDR4 memory in baseband, control, or network-processing subsystems. The 8Gbit density supports buffering and protocol workloads, while the 96-ball FBGA package facilitates compact board layouts. Telecommunications equipment commonly requires strict supply-noise, signal-integrity, and long-term availability controls, so the memory controller, power regulators, and thermal design should be qualified together. Verify temperature, endurance, and lifecycle requirements against the exact product documentation.
Recommended
Embedded Control Systems
The MT40A512M16HA-083E can support embedded processors, FPGAs, and industrial SoCs that need external DDR4 memory for working data, graphics buffers, or network queues. Its 16-bit organization is well suited to memory controllers designed for wider DDR channels, and the 1.2V supply reduces system power compared with legacy memory technologies. The design must account for package ballout, routing topology, VPP generation, refresh configuration, and thermal rise. Use the exact Micron datasheet and controller support list to confirm electrical and timing compatibility.

Key Differentiators
- Verified 512M x 16 organization (vs MT40A512M16JY-083E)
- Documented 1.2V pseudo open-drain interface and internal VREFDQ (vs HGD48G16M26)
- Temperature-dependent refresh information (vs MT40A512M16LY-062E)
Design Notes
Route DDR4 command, address, control, and data signals using the topology and impedance requirements in Micron's DDR4 design guidance. The 1.2V pseudo open-drain interface depends on correct return paths, termination networks, and clean references. Avoid long stubs and unnecessary layer transitions, and place fly-by routing components according to the memory-controller requirements.
Provide stable VDD/VDDQ at 1.2V plus or minus 60mV and VPP at 2.5V within the stated -125mV to +250mV tolerance. Use low-noise regulators and place decoupling capacitance close to the memory power balls. Validate ripple and transient response at the device pins rather than relying only on measurements at the power supply.
The 96-ball FBGA requires adequate board copper and, where necessary, thermal vias to spread heat from the memory device. Check junction-temperature limits against the actual ambient temperature, memory activity, airflow, and nearby power components. The supplied data does not provide a complete thermal resistance or operating-temperature specification, so use the exact Micron documentation for final thermal calculations.
Compliance Information
RoHS compliance is stated in the supplied Micron information. REACH, lead-free, halogen-free, and conflict-minerals declarations were not provided and remain unknown.
