W9825G2JB-75

The W9825G2JB-75 is a 256 Mbit synchronous dynamic RAM (SDRAM) device organized as 16M × 16 (4M × 4 banks × 16 bits). It provides a parallel SDRAM interface in a compact 90‑TFBGA (8×13) package and is specified for operation at a 133 MHz clock frequency with a 5.4 ns access time.

This device is designed for use where a parallel SDRAM memory element with defined voltage and temperature ranges is required. Key electrical parameters include a supply voltage range of 3.0 V to 3.6 V and an operating ambient temperature range of 0°C to 70°C.

Key Features

• Memory Type & Architecture 256 Mbit SDRAM organized as 16M × 16 (4M × 4 banks × 16 bits), supporting burst-oriented access.
• Performance Specified for a 133 MHz clock frequency with a 5.4 ns access time to meet mid‑range synchronous memory timing.
• Interface Parallel SDRAM interface suitable for systems that require conventional DRAM bus signaling.
• Voltage Supply Operates from 3.0 V to 3.6 V, enabling compatibility with standard 3.3 V system rails.
• Package 90‑TFBGA (8×13) supplier device package for a small-footprint, surface-mount implementation.
• Operating Temperature Rated for 0°C to 70°C (TA), appropriate for commercial temperature-range applications.

Typical Applications

• Parallel memory expansion — Provides 256 Mbit of SDRAM in a 16M × 16 organization for systems requiring parallel DRAM.
• Embedded systems — Compact 90‑TFBGA package and standard voltage range support space-constrained board designs using a 3.3 V rail.
• Mid-performance synchronous memory — 133 MHz operation and 5.4 ns access time for designs that need deterministic SDRAM timing.

Unique Advantages

• High-density SDRAM — 256 Mbit capacity in a single device reduces component count for designs needing larger DRAM arrays.
• Standard parallel SDRAM architecture — 16M × 16 organization with multiple banks supports burst-oriented access patterns.
• Compact BGA package — 90‑TFBGA (8×13) packaging minimizes PCB footprint while providing a robust surface-mount solution.
• System-level compatibility — 3.0 V to 3.6 V supply and 133 MHz clock support integration with common 3.3 V systems and SDRAM controllers.
• Commercial temperature rating — 0°C to 70°C ambient operating range for standard commercial applications.

Why Choose W9825G2JB-75?
