4RCD0232KC1ATG

Overview

The 4RCD0232KC1ATG is a Gen 2.5 DDR4 registered clock driver (RCD) compliant with JEDEC standards, designed for enterprise-class server RDIMMs, LRDIMMs, and UDIMMs. It operates with a 1.2V supply voltage and supports SDRAM types up to 3200 MT/s. The device features a register and PLL function within a 253-ball FCCSP package measuring 13.5 x 8.0 x 1.4 mm with a 0.65mm pitch. It is optimized for DDR4 speeds including 1600, 1866, 2133, 2400, 2667, 2933, and 3200 MT/s.

Feature Summary

• Supports CKE power-down operation modes and direct or encoded quad chip select configurations.
• Provides pinout-optimized PCB layout compatibility for DDR4 RDIMM, LRDIMM, and UDIMM applications.
• Offers access to internal control words for configuring device features and adapting to different system applications.

Applications

• Enterprise-class server Registered DIMMs (RDIMMs)
• Load Reduced DIMMs (LRDIMMs)
• Unbuffered DIMMs (UDIMMs)

Procurement Notes

Verify the specific suffix 'ATG' against official Renesas documentation to confirm the tray carrier type and operating temperature range. Ensure the component matches the required JEDEC compliance level for your target DDR4 memory speed. Cross-reference the package dimensions and lead count with your PCB footprint specifications before procurement.

Selection Notes

Select this component when designing systems requiring a Gen 2.5 DDR4 RCD for enterprise servers. It is suitable for applications needing support for multiple DDR4 speeds up to 3200 MT/s. Consider its compatibility with data buffers like the 4DB0232KC and temperature sensors such as the TSE2004GB2C0 for integrated memory subsystem design.

Part Context

This part belongs to the 4RCD0232K family of registered clock drivers from Renesas Electronics Corporation. It serves as a critical interface component in high-performance computing memory architectures, facilitating signal integrity and timing control for DDR4 memory modules in server environments.

Replacement Considerations

Check for updated suffixes or newer generation RCDs from Renesas that may offer enhanced performance or availability. Verify pin-to-pin compatibility if considering alternative vendors, ensuring all electrical parameters and package dimensions match exactly.
