MPN: NT5CB256M16CP-DII ✓ פעילNT5CB256M16CP-DII סקירה
DDR3L SDRAM (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory that operates at a lower voltage (1.35V) compared to standard DDR3 (1.5V), reducing power consumption by up to 20% while maintaining similar performance. It is widely used in computing, networking, and embedded systems where energy efficiency is critical. DDR3L is part of the DDR SDRAM family, which includes DDR, DDR2, DDR3, and DDR4, each offering increased bandwidth and lower power.
Key features include a 16-bit data bus, 8 internal banks, burst lengths of 8 and 4 (with burst chop), on-die termination (ODT), and programmable CAS latency. The device supports auto-refresh and self-refresh modes, with a refresh interval of 7.8us at 85C and 3.9us at 95C. It also features a temperature-compensated self-refresh (TCSR) for improved reliability in high-temperature environments.
The NT5CB256M16CP-DII utilizes Nanya's advanced C-die process technology, enabling high density and low power. The memory operates from a 1.35V core supply and a 1.5V I/O supply (for DDR3L, VDDQ is 1.35V). It supports data transfer rates up to 1600 Mbps per pin, providing a peak bandwidth of 3.2 GB/s per device. The device includes a programmable mode register for configuring CAS latency, burst length, and other operating parameters.
Typical applications include embedded computing, networking equipment (routers, switches), industrial automation, and automotive infotainment systems. Its low voltage and high density make it ideal for power-sensitive designs, while the industrial temperature range (-40C to +95C) ensures reliable operation in harsh environments.
When designing with this device, ensure proper decoupling capacitors near the power pins and follow the PCB layout guidelines in the datasheet to minimize signal integrity issues. The device requires a stable 1.35V supply and a separate VDDQ supply; both must be within specified tolerances.

הערות תכנון
Place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin. Use a solid ground plane and minimize trace lengths for address and data lines to reduce signal integrity issues. Follow the layout guidelines in the Nanya datasheet for DDR3L routing.
The industrial temperature range allows operation up to 95C, but ensure adequate airflow or heatsinking in high-ambient environments. The device's power dissipation depends on operating frequency and load; calculate worst-case power and verify junction temperature stays within limits.
Ensure VDD and VDDQ are within 1.283V to 1.45V. Do not exceed the absolute maximum ratings. Properly terminate the clock and data lines with ODT settings. Verify the mode register programming for correct CAS latency and burst length.
