W9825G6JB-6I

Memory IC Overview

The W9825G6JB-6I is a high-speed synchronous dynamic random access memory (SDRAM) manufactured by Winbond. It features an organization of 4M words x 4 banks x 16 bits, delivering up to 166 MHz clock frequency and compliant with the 166MHz/CL3 specification. The device operates on a 3.3V ± 0.3V power supply with LVTTL interface standards. It supports standard and low-power self-refresh modes, burst lengths of 1, 2, 4, 8, and full page, and includes auto-precharge capabilities. Designed for industrial applications, it guarantees operation within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports interleaved bank operations to hide precharging time and maximize performance through programmable mode registers.
• Features burst read and single write modes with byte data control via LDQM and UDQM pins.
• Includes power down and clock suspend modes to reduce power consumption during idle states.
• Packaged in a lead-free TFBGA 54-ball format compliant with RoHS standards.

Memory IC Applications

• Main memory for high-performance computing applications
• Industrial embedded systems requiring wide temperature tolerance
• Consumer electronics utilizing SDRAM architecture

Memory IC Procurement Notes

Verify component authenticity against official Winbond documentation before integration. Confirm that the specific ordering suffix corresponds to the required speed grade (-6I) and operating temperature range (-40°C to +85°C). Ensure compatibility with system voltage levels (3.3V ± 0.3V) and interface standards (LVTTL). Check for any product change notifications or revision updates that may affect pinout or electrical characteristics prior to final design approval.

Memory IC Selection Notes

Select this component when a 16-bit data bus width and 64Mbit total capacity are required for industrial-grade environments. The -6I suffix specifically denotes compliance with the 166MHz/CL3 specification guaranteed for temperatures between -40°C and +85°C. Consider the TFBGA 54-ball package constraints for PCB layout. Verify that the application benefits from the multiple-bank interleaving feature to optimize memory access latency compared to single-bank alternatives.

Memory IC Part Context

This part belongs to the W9825G6JB series of SDRAMs produced by Winbond Electronics. The series offers various speed grades including -6, -6I, and -75, differentiated primarily by clock frequency compliance and operating temperature ranges. The -6I variant is distinctively rated for industrial temperatures, whereas other variants like -6 or -75 are typically limited to commercial ranges. All variants share the same 4M x 4 Banks x 16 Bits organization and physical TFBGA 54-ball packaging.

Memory IC Replacement Considerations

Direct substitutes include other W9825G6JB variants such as W9825G6JB-6 or W9825G6JB-75 if the industrial temperature rating is not critical. Cross-referencing with similar density SDRAMs from other manufacturers requires careful verification of pinouts, timing parameters, and voltage levels.
