7 / 14 page HYR 16xx20G/HYR 18xx20G Rambus RIMM Modules INFINEON Technologies 7 7.00 RDQB8 … RDQB0 B61, A61, B63, A63, B65, A65, B67, A67, B69 I/O RSL Data bus B. A 9-bit bus carrying a byte of read or write data between the Channel and the RDRAM. RDQB8 is non-functional on modules with x16 RDRAM devices. RROW2 … RROW0 B77, A75, B75 I RSL Row bus. 3-bit bus containing control and address information for row accesses. RSCK A59 I V CMOS Serial Clock input. Clock source used to read from and write to the RDRAM control registers. SA0 B53 I SVDD Serial Presence Detect Address 0. SA1 B55 I SVDD Serial Presence Detect Address 1. SA2 B57 I SVDD Serial Presence Detect Address 2. SCL A53 I SVDD Serial Presence Detect Clock. SDA A55 I/O SVDD Serial Presence Detect Data (Open Collector I/O). SIN B36 I/O V CMOS Serial I/O for reading from and writing to the control registers. Attaches to SIO0 of the first RDRAM on the module. SOUT A36 I/O V CMOS Serial I/O for reading from and writing to the control registers. Attaches to SIO1 of the last RDRAM on the module. SVDD A56, B56 –– SPD Voltage. Used for signals SCL, SDA, SWE, SA0, SA1 and SA2. SWP A57 I SVDD Serial Presence Detect Write Protect (active high). When low, the SPD can be written as well as read. V CMOS A35, B35, A37, B37 –– CMOS I/O Voltage. Used for signals CMD, SCK, SIN, SOUT. V DD A41, A42, A54, A58, B41, B42, B54, B58 –– Supply voltage for the RDRAM core and interface logic. V REF A51, B51 –– Logic threshold reference voltage for RSL signals. Module Connector Pad Description (cont’d) Signal Module Connector Pads I/O Type Description |
