W9864G6JB-6I

Memory IC Overview

The W9864G6JB-6I is a high-speed synchronous dynamic random access memory (SDRAM) manufactured by Winbond Electronics. It features a storage organization of 1M words x 4 banks x 16 bits, providing a total capacity of 64 Mbit. The device supports a maximum clock frequency of 166 MHz with a CAS latency of 3. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 3.3V ± 0.3V power supply. The component is housed in a 60-ball VFBGA package measuring 6.4x10.1 mm.

Memory IC Feature Summary

• Supports burst read and single write operations with programmable burst lengths including sequential and interleave modes.
• Features multiple bank architecture enabling interleaved operations to hide precharging time.
• Includes auto-precharge and controlled precharge capabilities for efficient row management.
• Offers self-refresh mode and power-down mode for optimized power consumption.

Memory IC Applications

• High-performance main memory systems
• Industrial embedded applications requiring wide temperature tolerance
• Consumer electronics utilizing LVTTL interfaces

Memory IC Procurement Notes

Verify the specific speed grade suffix (-6I) against the required operating temperature range and voltage specifications. Confirm that the VFBGA-60 package dimensions align with the target PCB layout. Ensure compatibility with LVTTL interface standards during system integration.

Memory IC Selection Notes

Select this component when a 64 Mbit SDRAM solution is required for industrial environments. The -6I suffix specifically denotes compliance with the -40°C to +85°C operating range. Consider the 16-bit data bus width and 166 MHz performance limits relative to system bandwidth requirements.

Memory IC Part Context

This part belongs to the W9864G6JB series of SDRAMs from Winbond. It shares architectural similarities with other members like the W9864G6KH but differs in packaging and specific electrical characteristics. The series is designed for general-purpose memory applications requiring reliable synchronous data access.

Memory IC Replacement Considerations

Direct substitutes include the W9864G6JB-6A, which shares identical electrical and thermal specifications. Verify pinout compatibility before substitution.
