AT28C256-20DM/883 Frequently Asked Questions (FAQ)
-
The AT28C256-20DM/883 has an operating temperature range of -55°C to 125°C.
-
The device should be stored in a dry, cool place, away from direct sunlight and moisture. It should be handled with anti-static precautions to prevent electrostatic discharge (ESD) damage.
-
The recommended power-up sequence is to apply VCC before applying any input signals. The device should be powered up monotonically, with VCC reaching its final value before any input signals are applied.
-
The optimal clock frequency depends on the specific application and system requirements. The AT28C256-20DM/883 can operate at frequencies up to 20 MHz, but the actual frequency used should be determined based on the system's timing requirements and noise tolerance.
-
Using a 5V power supply may exceed the maximum rating of the device and can cause permanent damage. The device is designed to operate at 3.3V, and using a higher voltage can lead to reduced reliability and lifespan.
