Frequently asked questions
How do I connect it to a microcontroller?
It uses a parallel bus: 13 address lines, 8 data lines, and control signals CS, OE and WE. A microcontroller with enough free pins or an external address latch is needed to drive it.
Is it compatible with a 3.3 V system?
The standard device is designed for a 5 V supply. Using it with a 3.3 V system requires checking the datasheet and matching logic levels, so a level shifter may be needed.
