MT40A1G8WE-075E Übersicht
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is the fourth generation of DDR memory, offering higher speed and lower power than its predecessors. It uses a 1.2V supply (VDD and VDDQ) with a separate 2.5V VPP for wordline boost, and features on-die termination (ODT), internal VREFDQ generation, and pseudo-open-drain I/O. DDR4 achieves data rates up to 3200 MT/s, with the -075E speed grade indicating 2666 MT/s operation.
Key features include a refresh time of 8192 cycles at TC temperature range: 64ms at -40°C to 85°C, 32ms at >85°C to 95°C, and 16ms at >95°C to 105°C. The device supports on-die, internal, adjustable VREFDQ generation and 1.2V pseudo-open-drain I/O. It is available in industrial temperature grades (AIT) and standard temperature grades, with options for automotive (AEC-Q100) qualification in some variants.
Technically, the MT40A1G8WE-075E utilizes Micron's advanced DRAM process technology, achieving high density with low power consumption. The 78-ball FBGA package provides excellent thermal and electrical performance, with a ball pitch of 0.8mm. The device supports burst lengths of 8 and 4, and features programmable CAS latency, additive latency, and write recovery time.
Typical applications include servers, networking equipment, high-performance computing, and embedded systems requiring high memory bandwidth. The 1G x 8 organization is ideal for error-correcting code (ECC) modules and systems with multiple memory channels.
When designing with this component, ensure proper decoupling capacitors near the VDD and VDDQ pins, and follow Micron's layout guidelines for DDR4 routing to maintain signal integrity at 2666 MT/s.

- Proven Micron quality and supply chain (vs. YZ48G08V-F7HPI-M)
Designhinweise
For DDR4 routing at 2666 MT/s, maintain controlled impedance of 40-50 ohms for single-ended signals and 80-100 ohms differential. Keep trace lengths matched within ±10 mils for DQ/DQS groups. Place decoupling capacitors (0.1uF and 1uF) close to VDD and VDDQ pins, and use a solid ground plane beneath the FBGA package.
The MT40A1G8WE-075E has a maximum operating temperature of 105°C. Ensure adequate airflow or heatsinking in high-density modules. The refresh rate increases at higher temperatures (32ms at >85°C), which may impact performance. Monitor junction temperature and derate if necessary.
Use on-die termination (ODT) settings as recommended in the Micron datasheet to minimize reflections. For 2666 MT/s, set ODT to RZQ/7 (34 ohms) for writes and RZQ/6 (40 ohms) for reads. Ensure VREFDQ calibration is performed during initialization for optimal signal margins.
Compliance-Informationen
Standard variant is not AEC-Q100 qualified; AIT:B variant is automotive grade. RoHS compliant per Micron product page.
