W9825G6JB-6I TR

The W9825G6JB-6I TR is a 256 Mbit synchronous DRAM (SDRAM) organized as 4M × 4 banks × 16 bits (16M × 16). It implements high-speed, burst-oriented SDRAM operation with an LVTTL memory interface and is offered in a 54‑TFBGA (8×8) package.

Designed for systems that require synchronous, high-throughput volatile memory, this device supports a clock frequency of 166 MHz, a 3.0–3.6 V supply range and an operating temperature range of −40 °C to 85 °C.

Key Features

• Core / Memory Architecture Organized as 4M × 4 banks × 16 bits (equivalent to 16M × 16) delivering 256 Mbit of volatile SDRAM storage.
• Performance Up to 166 MHz clock frequency and 5 ns access time for synchronous burst transfers and high data throughput.
• SDRAM Functionality Supports burst read/write, auto-precharge, self-refresh and power-down modes as described in the device functional command set.
• Interface LVTTL memory interface for standard synchronous control signaling.
• Power Rated for a supply voltage range of 3.0 V to 3.6 V to match common 3V system rails.
• Package 54‑TFBGA (8×8) supplier device package for compact board-level integration.
• Operating Temperature Industrial temperature support: −40 °C to 85 °C (TA) for designs requiring extended ambient range.

Typical Applications

• Industrial control and automation — Extended temperature support and industrial-grade specification (-6I) make it suitable for controllers and PLC modules requiring reliable volatile memory.
• Embedded high-speed buffering — Synchronous burst operation and 166 MHz clock capability enable use as working memory or data buffers in embedded systems.
• Networking and communications equipment — High-throughput SDRAM operation supports buffering and packet handling in synchronous designs.

Unique Advantages

• Industrial temperature capability: Guaranteed operation from −40 °C to 85 °C, supporting deployment in extended‑range environments.
• High synchronous throughput: 166 MHz clocking and 5 ns access time enable fast burst transfers for performance-sensitive memory tasks.
• Standard LVTTL interface: Simplifies timing and signal-level integration with LVTTL-based memory controllers and logic.
• Compact BGA footprint: 54‑TFBGA (8×8) package reduces PCB area while providing a robust soldered connection.
• Comprehensive SDRAM feature set: Supports burst lengths, auto-precharge, self-refresh and power-down modes for flexible memory management.
• Wide supply voltage window: 3.0–3.6 V tolerance accommodates common 3V system rails and reduces supply constraints.

Why Choose W9825G6JB-6I TR?
