MT40A512M16LY-062E:E Overview
A DDR4 SDRAM is a synchronous dynamic random-access memory that uses an 8n-prefetch architecture, dual-rank or single-rank banking, and a bank-group topology introduced in the JEDEC JESD79-4 standard. In the modern memory hierarchy, DDR4 sits between LPDDR4 (mobile, low power) and HBM (high bandwidth, stacked) as the mainstream workhorse DRAM for servers, desktops, embedded computing, and networking. Each generation introduces tighter timing budgets, lower voltage rails, and higher peak transfer rates; DDR4-3200 doubles the peak transfer rate of DDR3-1600 while cutting VDD from 1.5 V to 1.2 V.
The MT40A512M16LY-062E:E supports JEDEC-standard DDR4 features including fine granularity refresh, low-power auto self-refresh (LPASR), per-DRAM addressability, multipurpose register (MPR) readouts, command/address (CA) parity, and gear-down timing modes. The x16 organization with 16-bit data width suits applications that require moderate bandwidth in a small footprint, such as FPGAs, networking line cards, industrial HMI controllers, and embedded vision subsystems.
Industrial temperature grade parts in this family (IT:E suffix) operate from -40C to +95C, while the commercial-grade -062E:E part is typically rated 0C to +95C. The 96-ball FBGA uses a standard JEDEC ballout for x16 DDR4, enabling PCB layout reuse across density variants of the same family.
Typical applications include networking switches and routers, FPGA-based accelerators (as a companion to Kintex/UltraScale FPGAs), industrial PCs and SBCs, telecom baseband processing, and edge-AI inference platforms. Designers commonly pair this part with a memory controller IP core or a host SoC that supports DDR4-3200.
When designing with this device, ensure the PCB fly-by topology recommended by Micron is followed for the address/command/control nets, with VTT termination at the far end and matched DQ/DQS trace lengths. Decoupling must follow the Micron reference layout for the 96-ball FBGA, with VPP decoupling placed within 100 mils of the balls.

Typical Applications
MT40A512M16LY-062E:E is suitable for 6 applications: Networking Switch and Router Line Cards, FPGA-Based Accelerator Memory (Xilinx Kintex/UltraScale), Industrial PC and Single-Board Computing, Telecom Baseband and Radio Unit Processing, Edge AI Inference Platforms, Automotive Infotainment and ADAS.
Networking Switch and Router Line Cards
The MT40A512M16LY-062E:E provides 6.4 GB/s peak bandwidth per x16 device (3200 MT/s x 16 bits) at 1.2 V VDD, fitting packet-buffer and forwarding-table requirements in Ethernet switches and core routers. Its on-die termination (ODT) simplifies the fly-by topology required by networking ASICs, while ZQ calibration and write-leveling compensate board-induced timing skew across long backplane traces. Two x16 devices stacked on a common data bus deliver 12.8 GB/s and 16 Gbit density. Designers pairing this DDR4 with switches like the Marvell Prestera series achieve sub-microsecond packet lookup latency.

FPGA-Based Accelerator Memory (Xilinx Kintex/UltraScale)
The MT40A512M16LY-062E:E pairs with Xilinx Kintex-7, Kintex UltraScale, and Kintex UltraScale+ FPGAs to provide external working memory for DSP, video processing, and AI inference pipelines. The 96-ball TFBGA shares the same footprint as Xilinx memory-interface MIG reference designs, and DDR4-3200 throughput saturates the 16-bit MIG interface at 6.4 GB/s. On-die ECC-free operation suits non-critical datapath buffering; write-leveling and DBI features simplify MIG PHY calibration. Layout follows Xilinx UG583 fly-by routing, with VTT termination at the FPGA far-end.
Recommended
Industrial PC and Single-Board Computing
The MT40A512M16LY-062E:E suits industrial PCs, edge controllers, and SBCs that need DDR4 capacity in a compact footprint. At 7.5 x 13.5 mm, the 96-ball TFBGA fits Mini-ITX and 3.5-inch SBC layouts, and the 1.2 V VDD reduces motherboard power budget versus DDR3L (1.35 V). The -062E speed grade (19 ns tRCD/tRP) is widely supported by x86 SoCs, embedded Ryzen V-series processors, and NXP i.MX8M application processors. Multiple parts can be paralleled for higher density without controller changes.
Recommended
Telecom Baseband and Radio Unit Processing
In 4G/5G radio units and baseband processing boards, the MT40A512M16LY-062E:E provides bulk DDR4 memory for FEC decoding, channel estimation buffers, and protocol-stack queues. DDR4-3200's 25.6 GB/s peak per quad-device array exceeds CPRI and eCPRI throughput requirements. The IT:E industrial-temp variant operates at -40C to +95C for outdoor radio-unit enclosures, and the wide voltage tolerance (1.14 V-1.26 V VDD) accommodates the noisy supplies typical of PoE-powered small cells.
Recommended
Edge AI Inference Platforms
The MT40A512M16LY-062E:E serves as weight/activation memory for edge-AI inference boards based on NPU or FPGA accelerators. Its 8 Gbit capacity holds quantized ResNet-50 or MobileNet weights for embedded vision, while 3200 MT/s throughput feeds activation tensors at >100 fps. The 1.2 V VDD aligns with low-power inference SoCs like NXP i.MX8M Plus and Rockchip RK3588, and ZQ calibration maintains signal integrity at the elevated operating temperatures of fanless edge enclosures.
Recommended
Automotive Infotainment and ADAS
The MT40A512M16LY-062E AUT:E / AAT:E / AIT:E speed-grade variants of this Micron DDR4 family serve automotive infotainment head units, instrument clusters, and ADAS domain controllers. AEC-Q100 qualification, combined with 3200 MT/s throughput, supports simultaneous operation of multi-display cockpit systems and surround-view ADAS pipelines. The x16 organization balances bandwidth and PCB-routing density in space-constrained automotive enclosures. Designers select the AAT:E variant for head-unit use, AUT:E for ADAS, and AIT:E for body controllers.

Key Differentiators
- JEDEC JESD79-4 standard x16 96-ball TFBGA ballout enables PCB reuse across temperature grades (vs AS4C512M16D4A-62BCN)
- Tiered temperature-grade portfolio (commercial, industrial, AEC-Q100) within a single package family (vs MT40A512M16LY-062E IT:E)
- Wide distributor availability with multiple cross-reference documents published (vs AS4C512M16D4B-62BCN)
Design Notes
Follow Micron's fly-by topology recommendation for address, command, and control nets: place termination VTT (0.6 V for DDR4) at the far end of each fly-by chain. Route DQ, DQS_t, DQS_c, and DBI_n as point-to-point 50-ohm impedance-matched differential traces with matched lengths within the byte lane (typically +/- 5 mil). VPP (2.5 V) decoupling capacitors must be placed within 100 mils of the TFBGA balls, with one 1 uF X7R cap per VPP ball plus one 4.7 uF bulk per channel.
Enable write leveling, read leveling, and ZQ calibration per JEDEC JESD79-4 mode-register sequence during controller initialization. The DDR4 command/address parity bit (PAR) must be verified before any read/write operation. CA parity error causes the DRAM to assert ALERT_n, which the controller must handle by re-issuing commands. Data bus inversion (DBI) reduces SSO noise on high-frequency transitions; ensure the controller's PHY supports DBI for x16 configurations to minimize ground bounce.
At full DDR4-3200 data rate with all 16 DQ lines switching, the 96-ball TFBGA dissipates approximately 0.5 W to 0.8 W typical, depending on read/write mix and termination strength. Maintain junction temperature below 95C for commercial grade or 105C for AEC-Q100 Grade 2. Forced airflow of 1-2 m/s is recommended in enclosed chassis. Avoid placing the TFBGA directly above a heat-dissipating component on the PCB backside, as the thin dielectric limits top-side heat spreading.
Do not apply VDD before VPP - the JEDEC JESD79-4 power-up sequence requires VPP (2.5 V) to stabilize before VDD (1.2 V) and VDDQ. Apply power in the order: VPP -> VDDQ -> VDD, with monotonic rise times. After power-up, hold RESET# low for at least 200 us to complete initialization. Do not assert CKE high before RESET# goes high, and do not issue any command before tRFC + tXPR timing window elapses after RESET# deassertion. Failure to follow power sequencing may damage the DRAM.
