256MB Buffered EDO DRAM DIMM 32-Mword x 72-bit, 4k Refresh, 2 Bank Module (36 pcs of 16M x 4 components)
ADE-203-872B (Z) Rev. 1.0 June 23, 1998 Description
The HB56SW3272ESK belong to 8-byte DIMM (Dual in-line Memory Module) family , and have been developed an optimized main memory solution for 4 and 8-byte processor applications. The HB56SW3272ESK is 32 M x 72 Dynamic RAM Module, mounted 36 pieces of 64-Mbit DRAM (HM5165405) sealed in TCP package and 2 pieces of 16-bit BiCMOS line driver sealed in TSSOP package. The HB56SW3272ESK offer Extended Data Out (EDO) Page Mode as a high speed access mode. An outline of the HB56SW3272ESK are 168-pin socket type package (dual lead out). Therefore, the HB56SW3272ESK make high density mounting possible without surface mount technology. The HB56SW3272ESK provide common data inputs and outputs. Decoupling capacitors are mounted beside each TCP on its module board. Note: Do not push the cover or drop the modules in order to protect from mechanical defects, which would be electrical defects.

Notes: 1. AC measurements assume t T = 2 ns. 2. An initial pause of 200 s is required after power up followed by a minimum of eight initialization cycles (any combination of cycles containing RAS-only refresh or CAS-before-RAS refresh). 3. Operation with the tRCD (max) limit insures that tRAC (max) can be met, tRCD (max) is specified as a reference point only; if t RCD is greater than the specified tRCD (max) limit, than the access time is controlled exclusively by tCAC . 4. Operation with the tRAD (max) limit insures that tRAC (max) can be met, tRAD (max) is specified as a reference point only; if t RAD is greater than the specified tRAD (max) limit, then access time is controlled exclusively by tAA . 5. Either t OED or tCDD must be satisfied. 6. Either t DZO or tDZC must be satisfied. 7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition times are measured between V IH (min) and VIL (max). 8. Assumes that t RCD tRCD (max) and tRAD tRAD (max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, t RAC exceeds the value shown. 9. Measured with a load circuit equivalent to 1 TTL loads and 100 pF. 10. Assumes that t RCD tRCD (max) and tRCD + tCAC (max) tRAD + tAA (max). 11. Assumes that t RAD tRAD (max) and tRCD + tCAC (max) tRAD + tAA (max). 12. Either t RCH or tRRH must be satisfied for a read cycles. 13. t OFF (max), tOEZ (max), tWEZ (max) and tOFR (max) define the time at which the outputs achieve the open circuit condition and are not referred to output voltage levels. 14. t WCS , t RWD, t CWD, t AWD and t CPW are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only; if t WCS tWCS (min), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if tRWD tRWD (min), tCWD tCWD (min), and tAWD tAWD (min), or tCWD tCWD (min), tAWD tAWD (min) and tCPW t CPW (min), the cycle is a read-modify-write and the data output will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, the condition of the data out (at access time) is indeterminate. 15. t DS and t DH are referred to CAS leading edge in early write cycles and to WE leading edge in delayed write or read-modify-write cycles. 16. t RASP defines RAS pulse width in EDO page mode cycles. 17. Access time is determined by the longest among t AA , t CAC and t CPA. 18. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device.

HB56SW3272ESK-5/6
19. When output buffers are enabled once, sustain the low impedance state until valid data is obtained. When output buffer is turned on and off within a very short time, generally it causes large V CC/V SS line noise, which causes to degrade V IH min/VIL max level. 20. t HPC (min) can be achieved during a series of EDO page mode write cycles or EDO page mode read cycles. If both write and read operation are mixed in a EDO page mode RAS cycle (EDO page mode mix cycle (1), (2)), minimum value of CAS cycle (tCAS + tCP + 2 tT) becomes greater than the specified t HPC (min) value. The value of CAS cycle time of mixed EDO page mode is shown in EDO page mode mix cycle (1) and (2). 21. Data output turns off and becomes high impedance from later rising edge of RAS and CAS. Hold time and turn off time are specified by the timing specifications of later rising edge of RAS and CAS between t OHR and t OH and between tOFR and t OFF. 22. t DOH defines the time at which the output level go cross. V OL = 0.8 V, VOH = 2.0 V of output timing reference level. 23. XXX: H or L (H: VIH (min) VIN VIH (max), L: VIL (min) VIN VIL (max)) ///////: Invalid Dout When the address, clock and input pins are not described on timing waveforms, their pins must be applied VIH or VIL.
