MPN: MT41K256M16HA-187EM:E ✓ Hoạt độngMT41K256M16HA-187EM:E Tóm tắt
DDR3L SDRAM (Low Voltage DDR3) is a type of synchronous dynamic random-access memory that operates at 1.35V, reducing power consumption by about 20% compared to standard DDR3 (1.5V). It is part of the DDR3 memory family, which uses double data rate architecture to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is backward compatible with DDR3, allowing operation in 1.5V mode when needed.
Key features include a 16n prefetch architecture, on-die termination (ODT), programmable CAS latency, and burst lengths of 8 and 4 (with burst chop). The device supports auto-refresh and self-refresh modes, and includes a temperature-compensated self-refresh (TCSR) for reduced power in idle states. The 96-ball FBGA package provides excellent thermal and electrical performance, with a ball pitch of 0.8mm.
The MT41K256M16HA-187EM:E operates over a temperature range of 0°C to +95°C (TC) and is RoHS compliant. It features a 1.35V core and I/O supply, with a VDDQ of 1.35V. The device is compatible with JEDEC DDR3L standards, ensuring interoperability with a wide range of controllers.
Typical applications include servers, networking equipment, industrial PCs, and embedded systems where low power and high density are critical. The 4Gb density and x16 organization make it ideal for memory modules and systems requiring 256M x 16 configuration.
When designing with this device, ensure proper decoupling capacitors near the VDD and VDDQ pins, and follow the PCB layout guidelines in the Micron datasheet to minimize signal integrity issues. The device supports a 1.5V compatible mode, allowing it to be used in systems designed for standard DDR3.

Ghi chú thiết kế
Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin to minimize power supply noise. Follow the layout guidelines in the Micron datasheet for DDR3L, including controlled impedance traces for DQ, DQS, and address/command signals. Ensure proper termination for the data bus.
The MT41K256M16HA-187EM:E operates up to +95°C. Ensure adequate airflow or heatsinking in high-temperature environments. The FBGA package has a thermal resistance that should be considered; refer to the datasheet for thermal characteristics and derating curves.
For 1866 MT/s operation, maintain signal integrity by using proper PCB stack-up, impedance matching, and minimizing trace length mismatches. Use on-die termination (ODT) settings as recommended in the datasheet to reduce reflections. Simulate the memory bus to verify timing margins.
