W9864G6KT-6

The W9864G6KT-6 is a high-speed SDRAM device organized as 1M × 4 banks × 16 bits (equivalent to 4M × 16) providing 64 Mbit of volatile memory with an LVTTL interface. It delivers synchronous DRAM operation up to 166 MHz and is supplied in a 54-ball TFBGA (8×8) package for compact board-level integration.

This device is intended for designs that require synchronous DRAM functionality with predictable timing (5 ns access time) and standard 3.0 V to 3.6 V supply operation, and it implements the common SDRAM command set and power modes for system memory management.

Key Features

• Memory Organization  Organized as 1M × 4 banks × 16 bits (4M × 16), providing a total memory size of 64 Mbit suitable for board-level DRAM needs.
• Performance  Supports operation up to 166 MHz and specifies a 5 ns access time; the device is offered in -6 speed grade optimized for 166 MHz/CL3 operation.
• SDRAM Command and Burst Support  Implements standard SDRAM functions including bank activate, burst read/write, auto-precharge, burst stop, and mode register programming for flexible access patterns.
• Power Management  Supports power-down and self-refresh modes to manage standby power and retain data during low-power intervals (per datasheet functional descriptions).
• Interface and Supply  LVTTL-compatible memory interface with recommended supply voltage range of 3.0 V to 3.6 V.
• Package  54-ball TFBGA (8×8) package offering a compact footprint for space-constrained circuit boards; package specifications are provided in the device datasheet.
• Operating Temperature  Specified operating ambient temperature range of 0°C to 70°C (TA) for the -6 grade device.

Typical Applications

• Board-level memory expansion  Use where a compact 64 Mbit SDRAM footprint is required for system memory or frame buffering on a PCB.
• Embedded system DRAM  Integration in embedded designs that require synchronous DRAM with LVTTL signalling and defined timing behavior.
• Consumer and electronics modules  Suitable for electronic modules and devices needing a small-package SDRAM with standard SDRAM features such as burst transfers and self-refresh.

Unique Advantages

• Clear memory sizing and organization: The 1M × 4 banks × 16-bit architecture (4M × 16) provides a straightforward 64 Mbit memory map for address and bank management.
• Predictable timing: Defined 5 ns access time and operation up to 166 MHz enable deterministic timing for systems designed around CL3 operation.
• Standard SDRAM feature set: Support for burst read/write, auto-precharge, power-down and self-refresh simplifies integration with common SDRAM controllers and memory controllers.
• Compact BGA package: The 54-ball TFBGA (8×8) package reduces board area while providing the required ballout for LVTTL connections and power rails.
• Wide supply tolerance: Operates across a 3.0 V to 3.6 V supply window to accommodate typical 3 V system power rails.
• Documented operation and timing: Detailed functional descriptions and timing diagrams in the device datasheet support design validation and timing closure.

Why Choose W9864G6KT-6?

The W9864G6KT-6 combines a compact 54-ball TFBGA footprint with a standard SDRAM architecture (1M × 4 banks × 16 bits) delivering 64 Mbit of volatile memory and operation up to 166 MHz.
