MT40A8G4NEA-062E:F TR

The MT40A8G4NEA-062E:F TR is a 32 Gbit TwinDie™ DDR4 SDRAM device implemented as an 8G×4 memory organization with a parallel interface. It combines two Micron 16Gb DDR4 dies into a dual-rank solution supporting JEDEC-standard ball-out in a 78-ball FBGA package (7.5 mm × 11 mm × 1.2 mm).

Designed for high-density DDR4 memory subsystems, this part provides a 3200 MT/s speed grade (‑062E), a 1.14–1.26 V supply range for VDD/VDDQ, and a commercial operating temperature range of 0°C to 95°C, delivering specified timing and refresh behavior for systems requiring robust parallel DRAM capacity.

Key Features

• Memory Architecture  TwinDie™ construction combining two 16Gb DDR4 dies into a single 32Gb (8G×4) device with two ranks (dual CS#, ODT, and CKE balls).
• Density & Organization  32 Gbit total capacity organized as 8G×4 with 16 banks per die and 2 ranks for expanded address space and rank-based operation.
• Performance / Timing  Speed grade -062E targets 3200 MT/s with CL-tRCD-tRP = 22-22-22 and key timing parameter tAA = 13.75 ns (access time 13.75 ns).
• Clock & I/O  1.6 GHz clock frequency with 1.2 V VDD/VDDQ nominal operation and 1.14–1.26 V specified supply range; VDDQ-terminated I/O per datasheet notes.
• Banking & Concurrency  Each rank includes 4 groups of 4 internal banks to support concurrent operation across bank groups.
• Package & Mounting  78-ball FBGA (7.5 mm × 11 mm × 1.2 mm) low-profile package; supplier device package listed as 78-FBGA (7.5×11).
• Temperature & Refresh  Commercial operating temperature 0°C to 95°C with defined refresh cycles: 8192 refresh cycles per 64 ms for 0°C–85°C and per 32 ms for 85°C–95°C.
• JEDEC Compliance  JEDEC-standard ball-out and timing references correlate to Micron’s 16Gb DDR4 SDRAM documentation for detailed electrical and timing specifications.

Typical Applications

• High-density DDR4 memory subsystems  Used where a 32 Gbit parallel DDR4 memory element is required for board-level memory implementations.
• Multi-rank memory designs  Dual-rank layout supports systems that leverage multiple ranks for increased memory capacity and address flexibility.
• Compact module and board designs  Low-profile 78-ball FBGA (7.5×11) packaging supports space-constrained PCBs requiring high-capacity DRAM.

Unique Advantages

• TwinDie two-rank integration:  Combines two 16Gb dies to deliver 32Gb in a single package with dual CS#, ODT, and CKE for rank-enabled designs.
• High-speed DDR4 timing:  -062E speed grade at 3200 MT/s with CL = 22 and tAA = 13.75 ns provides defined high-data-rate operation.
• Bank-group concurrency:  Four groups of four banks per rank permit concurrent operation across bank groups for improved internal access parallelism.
• Nominal 1.2 V operation:  VDD = VDDQ = 1.2 V with an allowed range of 1.14–1.26 V and VDDQ-terminated I/O for standard DDR4 electrical operation.
• Compact FBGA package:  78-ball FBGA (7.5 mm × 11 mm × 1.2 mm) offers a low-profile footprint for high-density board layouts.
• Commercial temperature qualification:  Specified operating range of 0°C to 95°C with corresponding refresh cycle requirements documented for system design.

Why Choose MT40A8G4NEA-062E:F TR?

The MT40A8G4NEA-062E:F TR positions itself as a high-density DDR4 SDRAM component for designs that require 32 Gbit capacity in an x4 parallel interface with dual-rank capability. Its TwinDie architecture, 3200 MT/s speed grade, and defined timing parameters (CL/tRCD/tRP = 22-22-22; tAA = 13.75 ns) make it suitable for systems that demand specified DDR4 performance and rank-based memory organization.

This device is appropriate for engineers specifying compact, board-level DRAM solutions that need JEDEC-standard ball-out in a 78-ball FBGA package, operation at nominal 1.2 V (1.14–1.26 V range), and commercial temperature operation from 0°C to 95°C. Detailed electrical and timing characteristics are provided in the manufacturer documentation to support system integration and validation.
