The DIMMs use -8 and -8B speed sort 8M 8 SDRAM devices in TSOP-54 packages to meet the PC100 requirement. Modules which use -10 parts are suitable for PC66 applications only. Decoupling capacitors are mounted on the PC board. The PC board design is according to INTEL’s PC SDRAM Rev. 1.0 module specification. The DIMMs have a serial presence detect, implemented with a serial E2PROM using the two pin I2C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128 bytes are available to the end user. All SIEMENS 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133.35 mm long footprint, with 1.25“ ( 31.75 mm) height.

The specified values are valid when addresses are changed no more than once during tCK(MIN.) and when No Operation commands are registered on every rising clock edge during tRC(MIN.). Values are shown per module bank. 2. The specified values are valid when data inputs (DQ’s) are stable during tRC(MIN.). 3. All AC characteristics are shown for device level. An initial pause of 100 µs is required after power-up, then a Precharge All Banks command must be given followed by 8 Auto Refresh (CBR) cycles before the Mode Register Set Operation can begin. 4. AC timing tests have VIL = 0.4 V and VIH = 2.4 V with the timing referenced to the 1.4 V crossover point. The transition time is measured between VIH and VIL. All AC measurements assume tT = 1 ns with the AC output load circuit show. Specified tAC and tOH parameters are measured with a 50 pF only, without any resistive termination and with a input signal of 1V/ns edge rate between 0.8 V and 2.0 V. . t CH 2.4 V 0.4 V CLOCK t CL t SETUP tT t HOLD INPUT 1.4 V t AC t LZ t AC I/O 50 pF t OH OUTPUT 1.4 V Measurement conditions for tAC and tOH t HZ SPT03404 If clock rising time is longer than 1ns, a time (tT/2 – 0.5) ns has to be added to this parameter.

Any time that the refresh Period has been exceeded, a minimum of two Auto (CBR) Refresh commands must be given to “wake-up“ the device. 9. Self Refresh Exit is a synchronous operation and begins on the 2nd positive clock edge after CKE returns high.
