4RCD0232KC0ATG8

Overview

The 4RCD0232KC0ATG8 is a JEDEC-compliant Gen 2.5 DDR4 registered clock driver (RCD) designed for enterprise-class server RDIMMs, LRDIMMs, and UDIMMs operating with a 1.2V supply. It supports data rates up to 3200 MT/s and features a 253-ball FCCSP package with 0.65mm pitch. The device includes integrated PLL functionality and supports CKE power-down modes, direct dual/quad CS modes, and encoded quad CS operation.

Feature Summary

• Provides registered clock driving capabilities compliant with JEDEC DDR4 standards for high-speed memory interfaces.
• Integrates phase-locked loop (PLL) circuitry to generate stable clock signals for memory modules.
• Supports multiple chip select configurations including direct dual, direct quad, and encoded quad CS modes.

Applications

• Enterprise-class server Registered DIMM (RDIMM) designs
• Load Reduced DIMM (LRDIMM) implementations
• Unbuffered DIMM (UDIMM) systems

Procurement Notes

Verify the specific suffix 'C0' against official Renesas documentation to confirm availability and exact electrical characteristics, as datasheets primarily reference the 'KC1' variant. Confirm moisture sensitivity level and lead-free status during procurement. Ensure compatibility with system requirements for 1.2V operation and 253-ball FCCSP packaging constraints.

Selection Notes

Select this component for DDR4 memory applications requiring Gen 2.5 RCD performance. Ensure the design accommodates the 253-ball FCCSP footprint with 0.65mm pitch. Verify that the target memory modules support the required CKE power-down and chip select modes. Confirm thermal management strategies for the specified operating temperature range.

Part Context

This component belongs to the 4RCD0232K family of DDR4 registered clock drivers from Renesas Electronics. These devices are critical for signal integrity in high-density memory subsystems. The family supports various speed grades and packaging options to meet diverse server and workstation memory architecture requirements.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-references may not guarantee compatibility with specific Gen 2.5 timing parameters or pinout optimizations required for the target memory configuration.
