W9751G6KB-25 TR

The W9751G6KB-25 TR is a 512 Mbit DDR2 SDRAM device organized as 32M × 16 with an 8M × 4 banks × 16 bit architecture. It provides a parallel memory interface in an 84-WBGA (8 × 12.5 mm) package and is specified for 1.7 V to 1.9 V supply operation and an operating temperature range of 0°C to 85°C.

Designed for applications that require standard DDR2 synchronous DRAM behavior, the device documentation includes detailed support for mode register programming, on-die termination (ODT), DLL control, extended mode registers (EMR), refresh, power-down and self-refresh sequences, and impedance adjustment routines to assist system memory integration.

Key Features

• Memory Core — 512 Mbit DDR2 SDRAM organized as 32M × 16 (8M × 4 banks × 16 bit) to provide parallel DDR2 memory architecture and banked operation.
• Performance — Operates with a clock frequency up to 400 MHz and specified access time of 57.5 ns; supports DDR2 burst and posted CAS/burst modes as described in the device functional documentation.
• Voltage and Timing — Specified supply voltage range of 1.7 V to 1.9 V and a write cycle time (word page) of 15 ns, with comprehensive AC timing and command operation tables in the datasheet.
• On-Chip Control and Configuration — Datasheet details include Mode Register Set (MRS), Extended Mode Registers (EMR), DLL enable/disable, On-Die Termination (ODT), and Off-Chip Driver (OCD) impedance adjustment for runtime configuration and signal integrity tuning.
• Power Management — Functional descriptions cover power-up/initialization, refresh, power-down, and self-refresh modes to support controlled low-power and retention behaviors.
• Package — 84-TFBGA / 84-WBGA (8 × 12.5 mm) package case suitable for surface-mount assembly with ball configuration and pin descriptions provided in the documentation.
• Operating Range — Specified operating temperature condition of 0°C to 85°C as provided in the product specifications and datasheet.

Typical Applications

• Embedded memory subsystems — Use as a 512 Mbit parallel DDR2 memory device in embedded designs requiring banked DDR2 SDRAM and documented mode register control.
• Board-level DRAM modules — Integration into custom memory modules or carrier boards where an 84-WBGA footprint and 1.7 V–1.9 V DDR2 operation are required.
• System memory for synchronous designs — Implement as parallel DDR2 SDRAM for systems that leverage burst read/write and posted CAS features documented in the device specification.

Unique Advantages

• Banked DDR2 architecture: 8M × 4 banks × 16 bit organization enables standard DDR2 banked operations as documented for efficient burst access patterns.
• Configurable termination and drivers: Includes documented ODT and OCD impedance adjustment and extended mode registers for tuning signal integrity on populated systems.
• Compact WBGA package: 84-ball WBGA (8 × 12.5 mm) package minimizes PCB footprint while providing a defined ball configuration and placement information in the datasheet.
• Comprehensive control sequencing: Datasheet provides detailed power-up/initialization, refresh, power-down and self-refresh sequences that support predictable memory behavior in system designs.
• Tight supply and timing specification: Operation at 1.7 V–1.9 V with specified clock frequency and timing parameters aids deterministic design and validation against the provided AC/DC characteristics.
