The 16Mx64 module is a single-bank DIMM that uses eight 16Mx8 DDR SDRAMs in 400 mil TSOP packages. The DIMM achieves high-speed data transfer rates of up to 266MHz. The DIMM is intended for use in applications operating from 100 MHz to 133 MHz clock speeds with data rates of 200 to 266 MHz. Clock enable CKE0 controls all devices on the DIMM. Prior to any access operation, the device CAS latency and burst type/ length/operation type must be programmed into the DIMM by address inputs A0-A11 and I/O inputs BA0 and BA1 using the mode register set cycle. These DIMMs are manufactured using raw cards developed for broad industry use as reference designs. The use of these common design files minimizes electrical variation between suppliers. The DIMM uses serial presence detects implemented via a serial EEPROM using the two-pin IIC protocol. The first 128 bytes of serial PD data are programmed and locked during module assembly. The last 128 bytes are available to the customer. All NANYA 184 DDR SDRAM DIMMs provide a high-performance, flexible 8-byte interface in a 5.25” long space-saving footprint.

All the DDR SDRAM address and control inputs are sampled on the rising Edge edge of their associated clocks. Negative The negative line of the differential pair of system clock inputs which drives the input to the Edge on-DIMM PLL. Activates the SDRAM CK signal when high and deactivates the CK signal when low. By A ctive High deactivating the clocks, CKE low initiates the Power Down mode, or the Self Refresh mode. Enables the associated SDRAM command decoder when low and disables the command Active decoder when high. When the command decoder is disabled, new commands are ignored Low but previous operations continue. Active When sampled at the positive rising edge of the clock, RAS , CAS , WE define the Low operation to be executed by the SDRAM. Reference voltage for SSTL-2 inputs Isolated power supply for the DDR SDRAM output buffers to provide improved noise immunity Selects which SDRAM bank is to be active. During a Bank Activate command cycle, A0-A11 defines the row address (RA0- RA11) when sampled at the rising clock edge. During a Read or Write command cycle, A0-A9 defines the column address (CA0-CA9) when sampled at the rising clock edge. In addition to the column address, AP is us ed to invoke Autoprecharge operation at the end of the Burst Read or Write cycle. If AP is high, autoprecharge is selected and BA0/BA1 define the bank to be precharged. If AP is low, autoprecharge is disabled. During a Precharge command cycle, AP is used in conjunction with BA0/BA1 to control which bank(s) to precharge. If AP is high all 4 banks will be precharged regardless of the state of BA0/BA1. If AP is low, then BA0/BA1 are used to define which bank to pre-charge.

Slew rate is measured between VOH (AC) and VOL(AC). 12. For command/address input slew rate >= 0.5 V/ns and < 1.0 V/ns. Slew rate is measured between VOH (AC) and VOL (AC). 13. CK/ CK slew rates are >= 1.0 V/ns. 14. These parameters guarantee device timing, but they are not necessarily tested on each device, and they may be guaranteed by design or tester characterization. 15. The specified timing is guaranteed assuming QFC is connected to a test load consisting of 20 pF to ground and a pull up resistor of 150 ohms to Vddq . 16. For each of the terms in parentheses, if not already an integer, round to the next highest integer. t CK is equal to the actual system clock cycle time. For example, for PC2100 at CL = 2.5, t DAL = (15ns/7.5ns) +(20ns/7.0ns) = 2 + 3 = 5. 17. An input setup and hold time derating table is used to increase t IS and t IH in the case where the input slew rate is below 0.5 V/ns.

Input slew rate is based on the lesser of the slew rates determined by either V IH (AC) to V IL (AC) or V I H (DC) to V IL (DC) , similarly f or rising transitions. 2. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on eachdevice. 18. An input setup and hold time derating table is used to increase t DS and t DH in the case where the I/O slew rate is below 0.5 V/ns.

These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on eachdevice. 19. An I/O Delta Rise, Fall Derating table is used to increase t DS and t DH in the case where DQ, DM, and DQS slew rates differ.

Input slew rate is based on the lesser of the slew rates determined by either V IH (AC) to V IL (AC) or V I H (DC) to V IL (DC) , similarly for rising transitions. 2. Input slew rate is based on the larger of AC to AC delta rise, fall rate and DC to DC delta rise, fall rate. 3. The delta rise, fall rate is calculated as: [1/(slew rate 1)] - [1/(slew rate 2)] For example: slew rate 1 = 0.5 V/ns; slew rate 2 = 0.4 V/ns. Delta rise, fall = (1/0.5) - (1/0.4) [ns/V] = -0.5 ns/V Using the table above, this would result in an increase in t DS and t D H of 100 ps. 4. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.
