Cypress has their datasheet online. Look for cy62256 at www.cypress.com. If you just want a shortcut to backed up RAM, you might investigate Dallas Semi's smartsocket DS1213. Simply replace the socket with DS1213 and piggy back 62256 on top. You (...) (27 years ago, 30-Dec-97, to lugnet.robotics.handyboard)

Hi all, Has anyone prototypes/built a version of the handyboard, etc, that used the non-multiplexed 68hc11F chip? Can you use the dl or dlm to download and use the icc ? If so, did you encounter any issues? tnx les (27 years ago, 30-Dec-97, to lugnet.robotics.handyboard)

Should be. You can probably find the power requirements from the manufacturere of the ram chip on the internet. Or if not, call the maunafacturer up and ask them to send you specs. ---...--- ericson mar Master of Engineering Candidate Project: (...) (27 years ago, 29-Dec-97, to lugnet.robotics.handyboard)
