W9751G6KB-25

The W9751G6KB-25 from Winbond Electronics is a 512 Mbit DDR2 SDRAM device in a parallel memory interface, packaged in an 84-ball WBGA. It implements a 32M × 16 memory organization (documented as 8M × 4 banks × 16-bit in the datasheet) and is designed for applications requiring standard DDR2 SDRAM functionality in a compact BGA footprint.

Key electrical and timing characteristics include a 400 MHz clock rating, 1.7 V–1.9 V supply range, a 15 ns write-cycle time (word/page) and an access time listed as 57.5 ns. The device is specified for commercial operating temperatures from 0 °C to 85 °C.

Key Features

• DDR2 SDRAM Technology  Standard DDR2 SDRAM architecture with support for burst read/write operations and parallel data interface.
• Memory Capacity & Organization  512 Mbit total capacity implemented as 32M × 16; datasheet describes an 8M × 4 banks × 16-bit bank architecture for command and bank management.
• Performance  Clock rating up to 400 MHz and documented access time of 57.5 ns, with a write cycle time (word/page) of 15 ns.
• Power  Low-voltage DDR2 operation with a supply range of 1.7 V to 1.9 V.
• Package & Mounting  84-ball WBGA package (84-TFBGA / 84-WBGA, 8 × 12.5 mm) designed for surface-mount PCB assembly.
• Command, Timing & Control  Supports Mode Register and Extended Mode Register programming, On-Die Termination (ODT), DLL enable/disable, and the full DDR2 command set (activate, read, write, precharge, refresh, power-down, self-refresh).
• Operational Range  Specified operating temperature range of 0 °C to 85 °C (TC) for commercial-temperature applications.

Typical Applications

• DDR2 memory for system designs  Use as parallel DDR2 SDRAM memory in systems that require a 512 Mbit density in a compact WBGA package.
• Legacy platform support  Replacement or maintenance of systems designed around parallel DDR2 SDRAM memory interfaces.
• Embedded and industrial-class equipment (commercial range)  Board-level memory expansion where 1.7 V–1.9 V DDR2 operation and a 0 °C–85 °C operating range are acceptable.

Unique Advantages

• 512 Mbit density in a compact BGA: Provides significant memory capacity while minimizing PCB area with an 84-ball WBGA footprint.
• Standard DDR2 feature set: Mode registers, extended mode registers, ODT and DLL controls provide flexible timing and termination configuration for system tuning.
• Low-voltage operation: 1.7 V–1.9 V supply range aligns with DDR2 power domains to reduce system power budget and simplify supply requirements.
• Documented timing and commands: Datasheet includes detailed command, timing, and electrical specifications (activate/read/write/precharge/refresh, power-down/self-refresh) to support deterministic design validation.
• Commercial temperature rating: Specified for 0 °C to 85 °C operation, suitable for a wide range of non-automotive electronics applications.
