The MCM6229BB is a 1,048,576 bit static random access memory organized
as 262,144 words of 4 bits. Static design eliminates the need for external clocks
ortimingstrobeswhileCMOScircuitryreducespowerconsumptionandprovides
for greater reliability.
The MCM6229BB is equipped with both chip enable (E) and output enable (G)
pins, allowing for greater system flexibility and eliminating bus contention problems.
The MCM6229BB is available in 300 mil and 400 mil, 28 lead surface–mount
SOJ packages.

ABSOLUTE MAXIMUM RATINGS (See Note)
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised
that normal precautions be taken to avoid
application of any voltage higher than maxi-
mum rated voltages to these high–impedance
circuits.
This CMOS memory circuit has been de-
signed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established. The circuit is in a test
socket or mounted on a printed circuit board
andtransverse air flow of at least500linearfeet
per minute is maintained.

NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to RECOMMENDED OPER-
ATING CONDITIONS. Exposure to higher than recommended voltages for
extended periods of time could affect device reliability.

NOTES:
1. W is high for read cycle.
2. Product sensitivities to noise require proper grounding and decoupling of power supplies as well as minimization or elimination of bus con-
tention conditions during read and write cycles.
3. All timings are referenced from the last valid address to the first transitioning address.
4. Addresses valid prior to or coincident with E going low.

6. Transition is measured ± 500 mV from steady–state voltage with load of Figure 1b.

TIMING LIMITS
+5 V
The table of timing values shows either a
minimum or a maximum limit for each param-
eter. Input requirements are specified from
the external system point of view. Thus, ad-
dress setup time is shown as a minimum
since the system must supply at least that
much time. On the other hand, responses
from the memory are specified from the de-
vice point of view. Thus, the access time is
shown as a maximum since the device never
provides data later than that time.

1. A write occurs during the overlap of E low and W low.
2. Product sensitivities to noise require proper grounding and decoupling of power supplies as well as minimization or elimination of bus con-
tention conditions during read and write cycles.
3. If G goes low coincident with or after W goes low, the output will remain in a high–impedance state.
4. All timings are referenced from the last valid address to the first transitioning address.
5. Transition is measured ± 500 mV from steady–state voltage with load of Figure 1b.
6. This parameter is sampled and not 100% tested.
