Short-Form Datasheet 4RCD0232KC1 DDR4RCD02 Register Command Address Buffer and Parity The 4RCD0232KC1 is a 32-bit 1:2 register command, Features address buffer with parity, designed for 1.2V VDD Pinout optimized DDR4 RDIMM PCB layout operation. The device is intended for DDR4-1600/1866/2133/2400/2666/2933/3200 RDIMM/LRDIMM applications. Supports CKE Power Down operation modes Planned decode logic to support DIMMs that Support Quad Chip Select Operation populate eight ranks of memory or higher. Planned Direct Dual CS Mode additional SI features to support DIMMs greater than 30mm height. Direct QuadCS Mode Encoded QuadCS Mode All inputs are pseudo-differential with an external or internal voltage reference. All outputs are full swing Provides access to internal control words for CMOS drivers optimized to drive single terminated configuring the device features and adapting in 25 to 50 traces in DDR4 RDIMM and LRDIMM different RDIMM and system applications applications. The clock outputs Yn t and Yn c and Compliant to JEDEC DDR4RCD02 Specification, the control net outputs QxCKEn, QxCSn and Revision 1.0 QxODTn can be driven with a different strengths to Packaging: 253-ball dual-pitch (0.50mm/0.65mm), compensate for different DIMM net topologies. By 15 20 grid, rectangular BGA disabling unused outputs the power consumption is Available in commercial temp. range (0C to reduced. 70C) and industrial temp. range (-40C to 85C) The 4RCD0232KC1 operates from a differential clock, CK t and CK c. Inputs are registered at the Block Diagram crossing of CK t going HIGH, and CK c going LOW. 4 The input signals could be either re-driven to the 4 5 6BQ 4 & 6BQ 4 :(BQ outputs or they could be used to access device 9UHI 4 > 4 % > 4 %*> 5 6BQ internal control registers when certain input conditions 4 &7BQ & 6BQ 4% 4% :(BQ 4% > > are met.
