Frequently Asked Questions
How can I operate this module as a 16-bit dynamic RAM?
You can use it by connecting DQ0 and DQ16, DQ1 and DQ17, up to DQ15 and DQ31.
What is the required initial procedure after powering on the unit?
An initial pause of 200ms is required, followed by at least eight RAS cycles (or eight CAS-before-RAS cycles with internal refresh).
What are the typical voltage requirements for this module?
The power supply voltage range is specified as –1 to +7 V. The operational power supply is +5 V.
Can I use this module in both 60ns and 70ns access speed settings?
Yes, ordering codes are available for the -60 (60 ns) and -70 (70 ns) versions, depending on your timing needs.
