IS43TR16256A-15HBL-TR 概要
DDR3 SDRAM (Double Data Rate Type 3 Synchronous Dynamic Random-Access Memory) is a type of synchronous dynamic random-access memory with a high bandwidth interface, double the data rate of DDR2. It achieves higher transfer rates by transferring data on both edges of the clock signal, effectively doubling the data rate without increasing the clock frequency. DDR3 is part of the SDRAM family, which includes DDR, DDR2, DDR4, and DDR5, and is widely used in computing, networking, and embedded systems.
Key features include a 4Gbit density, 16-bit I/O organization, 667 MHz clock speed, and a 20 ns CAS latency. The device supports programmable CAS latency, burst lengths of 8 and 4 (with burst chop), and on-die termination (ODT) for improved signal integrity. It also features auto-refresh and self-refresh modes for power saving, and a temperature-compensated self-refresh (TCSR) option.
The IS43TR16256A-15HBL-TR utilizes a high-performance CMOS process and a bank architecture with 8 internal banks, enabling efficient interleaving and high throughput. The device includes DLL (Delay-Locked Loop) for precise timing alignment and supports write leveling and read leveling for system timing calibration. Its low power consumption and high speed make it suitable for a wide range of applications.
Typical applications include networking equipment (routers, switches), industrial computing, embedded systems, and consumer electronics such as set-top boxes and smart TVs. The 1.5V operation and 96-ball TWBGA package allow for compact PCB designs with good thermal performance.
When designing with this device, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device requires a stable 1.5V supply and a reference voltage (VREF) for the I/O.

設計ノート
Ensure a stable 1.5V supply with adequate decoupling. Place 0.1uF and 1uF ceramic capacitors close to each VDD and VDDQ pin. The VREF voltage should be set to 0.75V (half of VDDQ) and bypassed with a 0.1uF capacitor to ground. Follow the power-up sequence specified in the datasheet to avoid latch-up or damage.
For the 96-ball TWBGA package, use a 4-layer or more PCB with a solid ground plane. Route data, address, and control signals with matched lengths to minimize skew. Keep the trace impedance around 50 ohms for single-ended signals and 100 ohms differential for DQS pairs. Place termination resistors for ODT as recommended in the datasheet.
Use on-die termination (ODT) to improve signal integrity on the data bus. Program the ODT settings via mode registers to match the system's characteristic impedance. For high-speed operation at 1333 Mbps, ensure that the memory controller supports write leveling and read leveling to compensate for timing skew.
