HYB 514175BJ/BJL-50/-55/-60
256k × 16 EDO-DRAM
The HYB 514175BJ is the new generation dynamic RAM organized as 262 144 words by 16-bit.
The HYB 514175BJ utilizes CMOS silicon gate process as well as advanced circuit techniques to
provide wide operation margins, both internally and for the system user. Multiplexed address inputs
permit the HYB 514175BJ to be packed in a standard plastic 400 mil wide P-SOJ-40-1 package.
This package size provides high system bit densities and is compatible with commonly used
automatic testing and insertion equipment. System oriented features include single + 5 V (± 10 %)
power supply, direct interfacing with high performance logic device families such as Schottky TTL.

Notes
All voltages are referenced to VSS.
ICC1, ICC3, ICC4 and ICC6 depend on cycle rate.
ICC1 and ICC4 depend on output loading. Specified values are obtained with the output open.
Address can be changed once or less while RAS = VIL. In case of ICC4 it can be changed once
or less during a hyper page mode (EDO) cycle
5. An initial pause of 200 µs is required after power-up followed by 8 RAS cycles of which at least
one cycle has to be a refresh cycle, before proper device operation is achieved. In case of using
the internal refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of
8 RAS cycles are required.
6. AC measurements assume tT = 2 ns.
7. VIH (MIN.) and VIL (MAX.) are reference levels for measuring timing of input signals. Transition times
are also measured between VIH and VIL.
8. Measured with the specified current load and 100 pF at VOL = 0.8 V and VOH = 2.0 V. Access
time is determined by the latter of tRAC, tCAC, tAA , tCPA , tOEA. tCAC is measured from tristate.
9. Operation within the tRCD (MAX.) limit ensures that tRAC (MAX.) can be met. tRCD (MAX.) is specified as
a reference point only. If tRCD is greater than the specified tRCD (MAX.) limit, then access time is
controlled by tCAC.
10.Operation within the tRAD (MAX.) limit ensures that tRAC (MAX.) can be met. tRAD (MAX.) is specified as
a reference point only. If tRAD is greater than the specified tRAD (MAX.) limit, then access time is
controlled by tAA.
11.Either tRCH or tRRH must be satisfied for a read cycle.
12.tOFF (MAX.), tOEZ (MAX.) define the time at which the output achieves the open-circuit conditions and
are not referenced to output voltage levels. tOFF is referenced from the rising edge of RAS or
CAS, whichever occurs last.
13.Either tDZC or tDZO must be satisfied.
14.Either tCDD or tODD must be satisfied.
15.tWCS, tRWD, tCWD and tAWD are not restrictive operating parameters. They are included in the data
sheet as electrical characteristics only. If tWCS > tWCS (MIN.), the cycle is an early write cycle and
data out pin will remain open-circuit (high impedance) through the entire cycle; if
tRWD > tRWD (MIN.), tCWD > tCWD (MIN.) and tAWD > tAWD (MIN.), the cycle is a read-write cycle and I/O will
contain data read from the selected cells. If neither of the above sets of conditions is satisfied, the
condition of I/O (at access time) is indeterminated.
16.These parameters are referenced to the CAS leading edge in early write cycles and to the WE
leading edge in read-write cycles.
