Description and Introduction

256M LVTTL interface SDRAM 133 MHz/100 MHz 4-Mword × 16-bit × 4-bank/8-Mword × 8-bit × 4-bank /16-Mword × 4-bit × 4-bank PC/133, PC/100 SDRAM **Introduction to HM5225165BTT-A6**  

The **HM5225165BTT-A6** is a high-performance **256Mb (16M x 16-bit) SDRAM (Synchronous Dynamic Random-Access Memory)** component designed for applications requiring fast data access and efficient memory management. Operating at a **3.3V supply voltage**, this SDRAM is optimized for use in embedded systems, networking equipment, and industrial electronics where reliable, high-speed memory is essential.  

Featuring a **synchronous interface**, the HM5225165BTT-A6 allows for precise timing control, enabling seamless integration with processors and controllers. Its **burst mode capability** enhances data transfer rates, making it suitable for real-time processing tasks. The component supports **auto-refresh and self-refresh modes**, ensuring data integrity while minimizing power consumption in low-activity states.  

With a **compact TSOP-II package**, the HM5225165BTT-A6 offers space-efficient solutions for PCB designs. Its **industrial-grade temperature tolerance** ensures stable performance in demanding environments.  

Engineers and designers favor this SDRAM for its balance of speed, power efficiency, and reliability, making it a practical choice for memory-intensive applications. Whether used in telecommunications, automation, or consumer electronics, the HM5225165BTT-A6 delivers consistent performance under varying operational conditions.
