04188CBLBB-25

Overview

The IBM 04188CBLBB-25 is a volatile synchronous static random-access memory (SRAM) integrated circuit. It provides an 8Mbit memory capacity organized for high-speed data processing applications. The component utilizes HSTL (High-Speed Transceiver Logic) interface technology to ensure signal integrity in high-frequency environments. It operates within a supply voltage range of 2.375V to 2.625V and supports an ambient operating temperature range from 0°C to 85°C. The device is housed in a 153-pin ball grid array (BGA) package.

Feature Summary

• Synchronous SRAM architecture for high-speed data access
• HSTL interface technology for reliable signal transmission
• Wide operating temperature range supporting industrial environments

Applications

• High-performance computing systems requiring fast volatile memory
• Network infrastructure equipment utilizing HSTL standards
• Industrial control systems operating within specified thermal limits

Procurement Notes

Verify the exact manufacturer part number against official IBM documentation before procurement. Confirm that the 153PBGA package type matches your board design requirements. Ensure compatibility with HSTL signaling levels and the specified 2.375V to 2.625V power supply rails. Check for any specific ordering suffixes or revisions that may affect electrical characteristics or pinout configurations.

Selection Notes

Select this component when synchronous SRAM performance is required with HSTL interface compatibility. Consider the 153-pin BGA footprint for PCB layout constraints. Evaluate the 0°C to 85°C operating range against your environmental conditions. Verify that the 8Mbit density meets your system's memory capacity needs without exceeding available address space.

Part Context

This component belongs to IBM's SRAM product line, designed for embedded memory solutions in enterprise hardware. Synchronous SRAMs are typically used as cache memory or buffer storage in processors and network controllers. The HSTL standard indicates its use in high-speed digital circuits common in server and storage subsystems.

Replacement Considerations

Consult official IBM replacement guides for direct substitutes. Ensure any alternative maintains identical HSTL interface specifications and 153PBGA package dimensions. Verify voltage and temperature ranges match the original requirements.
