W9825G6KB-6I

The W9825G6KB-6I from Winbond Electronics is a 256 Mbit high-speed synchronous DRAM (SDRAM) device organized as 4M × 4 banks × 16 bits. It is offered in a 54-TFBGA (8×8) package and uses an LVTTL memory interface.

Designed for systems requiring standard SDRAM functionality, the device supports operation to 166 MHz (166M words per second) with a 5 ns access time and the -6I grade provides an industrial case temperature range of −40°C to 85°C.

Key Features

• Core and architecture — 4M × 4 banks × 16 bits organization yielding 256 Mbit total SDRAM capacity (16M × 16 memory organization).
• Performance — Clock frequency up to 166 MHz and 5 ns access time; parts are sorted to the 166MHz/CL3 timing grade.
• Interface — LVTTL memory interface for standard SDRAM signaling.
• Power — Supply voltage range 3.0 V to 3.6 V.
• Temperature range — Industrial-grade -6I supports −40°C to 85°C (TCASE).
• Package — 54-TFBGA (8×8) supplier device package for compact board integration.
• SDRAM functionality — Supports standard SDRAM commands and modes including power-up and initialization, mode register programming, bank activate, burst read/write, auto-precharge, self-refresh and power-down.

Typical Applications

• PC-class memory subsystems — Suited to designs that follow the personal computer industrial timing standards at 166 MHz/CL3.
• Industrial and embedded systems — Industrial temperature rating (−40°C to 85°C for the -6I grade) for extended-environment use.
• Compact module designs — 54-TFBGA (8×8) package supports space-constrained PCBs requiring 256 Mbit SDRAM.

Unique Advantages

• High-speed SDRAM operation: 166 MHz clock capability with 5 ns access time for predictable data throughput.
• Complete SDRAM feature set: Native support for burst operations, auto-precharge and self-refresh to match standard memory controller flows.
• Industrial temperature support: −40°C to 85°C (TCASE) on the -6I grade for broader operating conditions.
• Compact BGA footprint: 54-TFBGA (8×8) package minimizes board area for high-density designs.
• Standard 3 V power domain: 3.0–3.6 V supply range compatible with typical 3 V SDRAM rails.

Why Choose W9825G6KB-6I?

The W9825G6KB-6I provides a commercial SDRAM option with a 256 Mbit density, a 4M × 4 banks × 16-bit architecture and standard SDRAM command support. Its 166 MHz operation and 5 ns access time address designs that require established SDRAM timing and burst access modes.

Packaged in a 54-TFBGA (8×8) and rated for a 3.0–3.6 V supply, with the -6I industrial temperature range of −40°C to 85°C, the device is appropriate for PC-class and industrial embedded designs where known SDRAM performance, a compact footprint, and industrial temperature capability are required.
