MSM548262

Notes: 1. Exposure beyond the "Absolute Maximum Ratings" may cause permanent damage

to the device.

2. All voltages are referenced to V .

3. These parameters depend on the cycle rate.

4. These parameters depend on output loading. Specified values are obtained with the

output open.

5. An initial pause of 200 ms is required after power up followed by any 8 RAS cycles

(TRG = "high") and any 8 SC cycles before proper device operation is achieved.

In the case of using an internal refresh counter, a minimum of 8 CAS before RAS

cycles instead of 8 RAS cycles are required.

6. AC measurements assume t = 5 ns.

7. V (Min.)andV (Max.)arereferencelevelsformeasuringtimingofinputsignals.

Also, transition times are measured between V and V .

8. RAM port outputs are measured with a load equivalent to 1 TTL load and 50 pF.

DOUT reference levels : V /V = 2.0 V/0.8 V.

9. SAM port outputs are measured with a load equivalent to 1 TTL load and 30 pF.

DOUT reference levels : V /V = 2.0 V/0.8 V.

10. t

(Max.) and t

(Max.) define the time at which the

levels. This parameter is sampled and not 100% tested.

11. Either t

or t

must be satisfied for a read cycle.

RCH

12. These parameters are referenced to CAS leading edge of early write cycles, and to

WE leading edge in TRG controlled write cycles and read modify write cycles.

13. t

and t

are not restrictive operating parameters.

AWD

WCS RWD CWD

They are included in the data sheet as electrical characteristics only.

If t ≥ t (Min.), the cycle is an early write cycle, and the data out pin will

≥ t

(Min.), the cycle is a read modify write cycle, and the data

out will contain data read from the selected cell; If neither of the above sets of

conditions are satisfied, the condition of the data out is indeterminate.

14. Operation within the t

(Max.) limit ensures that t

(Max.) can be met.

16. Input levels at the AC testing are 3.0 V/0 V.

17. Address (A0 - A8) may be changed two times or less while RAS = V .

18. Address (A0 - A8) may be changed once or less while CAS = V and RAS = V .

19. This is guaranteed by design. (t
