CY7C036 Dual-Port Design Consideration
–
Data Sheet Addendum
This design consideration applies to the Internal Power-On-
Reset (POR) circuit used on the CY7C036 and its derivatives
listed below.
Power supply ramp
—
The devices will function properly and
meet all data sheet specifications if the power supply ramp rate
is greater than 100 ns. If ramp is less than 100 ns, you may
see a non-destructive failure in which the device will not re-
spond to changes in address or clock, but the I/Os will respond
to the output enable.
Applications consideration
—
If the power supply ramps in less
than 100 ns, a small resistor (20
–
50
), a large capacitor, or an
RC network can be connected at the output of the power sup-
ply to ground. The addition of a resistor will help clean up the
power lines, while the capacitor will slow down the ramp rate
without the loss of any power. Contact your local Cypress FAE
for assistance as needed.
Troubleshooting
—
If a problem occurs with the part, power
down the device to ground and then power up again at slower
ramp rate (greater than 100 ns) in order to confirm that the
problem might be due to the POR circuit. If the dual-port func-
tions properly once the ramp rate is slowed to 100 ns or great-
er, then the POR circuit is at fault.
Applicable devices
—
All speed/package/temperature combi-
nations of the following:
CY7C09079
CY7C09179
Cypress design change
—
Cypress design team has identified
the root cause. A permanent circuit change and die revision
will be available beginning in October and will be identified by
the letter
“
A
”
in the part number.
