HB56A232BA/SBA Series
2,097,152-word x 32-bit High Density Dynamic RAM Module
ADE-203-722A (Z) Rev.1.0 Feb. 20, 1997 Description
The HB56A232BA/SBA is a 2M x 32 dynamic RAM module, mounted 4 pieces of 16-Mbit DRAM (HM5117800) sealed in SOJ package. An outline of the HB56A232BA/SBA is 72-pin single in-line package. Therefore, the HB56A232BA/SBA makes high density mounting possible without surface mount technology. The HB56A232BA/SBA provides common data inputs and outputs. Decoupling capacitors are mounted on the module board.

Notes: 1. AC measurements assume t T = 5 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 cycle or CAS-before-RAS refresh). If the internal refresh counter is used, a minimum of eight CAS-before-RAS refresh cycles are required. 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, then 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. 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). 6. 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. 7. Measured with a load circuit equivalent to 2 TTL loads and 100 pF. 8. Assumes that t RCD tRCD (max) and tRCD + tCAC (max) tRAD + tAA (max). 9. Assumes that t RAD tRAD (max) and tRCD + tCAC (max) tRAD + tAA (max). 10. Either t RCH or tRRH must be satisfied for a read cycles. 11. t OFF (max) defines the time at which the outputs achieve the open circuit condition and are not referred to output voltage levels. 12. Early write cycle only (tWCS tWCS (min)). 13. These parameters are referred to CAS leading edge in early write cycles. 14. t RASP defines RAS pulse width in Fast page mode cycles. 15. Access time is determined by the longest among t AA , t CAC and t CPA. 16. 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 / VSS line noise, which causes to degrade V IH min./ V IL max level. 17. All the V CC and VSS pins shall be supplied with the same voltages. 18. 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.
