YZ38F16SBB-9MFD-M Overview
DDR3 SDRAM (Double Data Rate 3 Synchronous Dynamic Random-Access Memory) is a type of volatile memory that transfers data on both edges of the clock, achieving high bandwidth. It is the third generation of DDR memory, succeeding DDR2, and is widely used in computing, networking, and embedded systems. DDR3L is a low-voltage variant that operates at 1.35V, reducing power consumption by about 20% compared to standard 1.5V DDR3, making it ideal for power-sensitive applications.
Key features include a 4Gb density (256M x 16), 96-ball FBGA package, industrial temperature range of -40°C to +85°C, and support for both 1.35V and 1.5V operation. The device meets JEDEC standards for DDR3 and DDR3L, including ZQ calibration with an external 240Ω ±1% resistor. It is designed for reliable operation in harsh environments, with wide-temperature screening and testing.
The YZ38F16SBB-9MFD-M is manufactured using a domestic (Chinese) supply chain, offering a secure and controllable source for critical applications. It is compatible with domestic platforms such as Fudan Micro, Phytium, Loongson, and Rockchip, and is available with development boards for evaluation. The device is also certified with ZZKK (domestic autonomous controllable) and WBK (pseudo-empty package) certifications, ensuring authenticity and quality.
Typical applications include industrial automation, embedded computing, networking equipment, and military/aerospace systems where long-term availability and wide-temperature operation are critical. The pin-to-pin compatibility with industry-standard DDR3 parts simplifies BOM management and reduces supply chain risk.
When designing with this device, ensure proper decoupling and signal integrity practices are followed, including placing 0.1µF and 10µF capacitors near the power pins and maintaining controlled impedance for the data and address lines. The device supports standard DDR3 termination and calibration schemes, so follow the JEDEC guidelines for layout and routing.

- Pin-to-pin compatibility with major brands (vs K4B4G1646E-BYMA)
Design Notes
Ensure proper decoupling: place 0.1µF and 10µF capacitors close to the VDD and VDDQ pins. Use a solid ground plane and maintain controlled impedance for data and address lines (typically 50Ω single-ended, 100Ω differential). Follow JEDEC layout guidelines for DDR3 to minimize signal integrity issues.
The device is rated for -40°C to +85°C. Ensure adequate airflow or heatsinking if the device is placed near other heat sources. The FBGA96 package has a thermal resistance that should be considered; refer to the datasheet for theta_JA values. For high-temperature environments, verify junction temperature stays within limits.
Verify the speed grade and voltage compatibility with your controller. The -9 grade supports DDR3-1866, but if your system is designed for DDR3-1600, it will still work. Ensure the ZQ calibration resistor (240Ω ±1%) is connected to the ZQ pin. Do not mix 1.5V and 1.35V operation without proper configuration.
