The DIMMs use 7-5 speed sorted 256 Mbit Synchronous DRAMs (SDRAMs) to meet the PC133-333 requirements and -8, -8A and -8B components for the standard PC100 applications. Decoupling capacitors are mounted on the PC board. The PC board design is according to INTEL’s PC100 module specification. The DIMMs have a serial presence detect, implemented with a serial E2PROM using the 2-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 Infineon 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.

These parameters depend on the cycle rate. These values are measured at 133 MHz for -7.5 modules and at 100 Mhz for -8 modules. Input signals are changed once during tCK, except for ICC6 and for standby currents when tCK = infinity. All values are shown per memory component. 2. These parameters are measured with continuous data stream during read access and all DQ toggling. CL = 3 and BL = 4 assumed and the VDDQ current is excluded. 3. All AC characteristics are shown on SDRAM component level. An initial pause of 100 µs is required after power-up, then a Precharge All Banks command must be given followed by eight 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 1 V/ns edge rate between 0.8 V and 2.0 V. 5. If clock rising time is longer than 1 ns, a time (tT/2 – 0.5) ns must be added to this parameter. 6. Rated at 1.4 V Data Book 11 12.99 HYS 64/72V64220GU SDRAM-Modules 7. If tT is longer than 1 ns, a time (tT – 1) ns has to be added to this parameter. 8. Anytime the Refresh Period has been exceeded, a minimum of two Auto-Refresh (CBR) commands must be given to “wake-up” the device. 9. Timing is asynchronous. If setup time is not met by rising edge of the clock then the CKE signal is assumed latched on the next cycle. 10.Self-Refresh Exit is a synchronous operation and begins on the second positive clock edge after CKE returns high. Self-Refresh Exit is not complete until a time period equal to tRC is satisfied after the Self Refresh Exit command is registered. 11.This is referenced to the time at which the output achieves the open circuit condition, not to output voltage levels. 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 t OH 50 pF OUTPUT 1.4 V Measurement conditions for tAC and tOH t HZ SPT03404 A serial presence detect storage device - E2PROM - is assembled onto the module.
