W9864G6JH-6I

The W9864G6JH-6I is a 64 Mbit synchronous dynamic random access memory (SDRAM) arranged as 4M × 16 (1M × 4 banks × 16 bits). It implements a parallel memory interface and supports standard SDRAM operations and command sequences as documented in the device datasheet.

Designed for systems requiring a compact parallel SDRAM solution, this -6I speed grade is specified to operate up to 166 MHz with CAS latency 3 and supports an ambient operating range of -40°C to 85°C. The device is supplied in a 54-lead TSOP (II) package (0.400", 10.16 mm width) and operates from a 3.0 V to 3.6 V supply.

Key Features

• Core Architecture Organized as 1M × 4 banks × 16 bits (4M × 16), providing a 64 Mbit capacity in a 16-bit data width.
• SDRAM Technology Synchronous DRAM supporting standard SDRAM command set including Mode Register Set, Bank Activate, Burst Read/Write, Auto-precharge, Self Refresh and Power-Down modes (as detailed in the device documentation).
• Performance -6I speed grade specified for operation up to 166 MHz with CAS latency 3 and an access time of 5 ns.
• Voltage and Power Rated supply voltage range from 3.0 V to 3.6 V.
• Package 54-lead TSOP (II) package, 0.400" (10.16 mm) width, for surface-mount implementation.
• Operating Temperature Specified ambient range of -40°C to 85°C for the -6I grade.

Typical Applications

• Parallel memory expansion Use where a 64 Mbit parallel SDRAM organized as 4M × 16 is required for system memory or buffering.
• Embedded systems Suitable for designs that require a 3.0–3.6 V SDRAM device in a compact 54-TSOP II package.
• Temperature-critical deployments Appropriate for applications needing operation across an ambient range of -40°C to 85°C (per -6I grade specification).

Unique Advantages

• Verified -6I speed grade: Provides operation up to 166 MHz with CAS Latency 3, enabling synchronous burst operation at that grade.
• Compact surface-mount package: 54-TSOP (II) footprint (0.400", 10.16 mm width) enables space-efficient board layouts.
• Standard SDRAM command support: Includes Mode Register Set, bank activate, burst read/write, auto-precharge, self-refresh and power-down modes as documented, allowing integration with conventional SDRAM controllers.
• <strong Wide operating voltage range: 3.0 V to 3.6 V supply accommodates common 3.3 V system rails.
• Extended ambient temperature: -40°C to 85°C specification for the -6I grade supports operation in a broad range of thermal environments.

Why Choose W9864G6JH-6I?

The W9864G6JH-6I offers a documented SDRAM implementation with a 64 Mbit capacity, a 16-bit parallel interface, and a compact 54-TSOP II package—an option for designs that require a defined-speed, parallel SDRAM device running up to 166 MHz and operating across -40°C to 85°C. Its support for standard SDRAM commands and modes simplifies integration with controllers designed for conventional SDRAM operation.

This device is suited for engineers specifying a discrete parallel SDRAM with clear electrical, timing and package specifications (3.0–3.6 V supply, 5 ns access time, CAS latency 3 at the -6I grade) and who require the form factor and thermal range provided by the 54-TSOP II package.
