What are the main features of the W9825G6KH-6?
The W9825G6KH-6 is a 256 Mbit (32 M × 8 × 4 banks) SDRAM memory chip that operates up to 166 MHz (5 ns access time), with support for clock frequencies up to 200 MHz. It uses a 3.3 V power supply and offers flexible burst lengths (1, 2, 4, 8, and full page), selectable CAS latencies (2 or 3), and modes such as self-refresh, auto precharge, and power-down for efficient power management. It also includes byte masking through LDQM/UDQM control and is packaged in a 54-pin TSOP II format, making it suitable for compact board designs.
What is it used for?
This SDRAM is typically used as main or auxiliary memory in embedded systems, networking equipment, game consoles, industrial controllers, digital appliances, and other applications requiring fast, temporary data storage. It provides high-speed random access, making it ideal for buffering, data processing, and real-time memory needs in microprocessor-based systems.
Does it have alternative parts?
Yes. Similar SDRAM from Winbond’s own family or other manufacturers like Micron, Samsung, and SK hynix can serve as alternatives. For example, 256 Mbit SDRAM parts with comparable speed and package types (such as 54-pin TSOP) from these vendors may be interchangeable depending on your system’s timing, refresh requirements, and board compatibility. Always verify electrical specs and pinout before substituting to ensure design compatibility.
