How should I go about hooking up the SDRAM addressing lines from the K66 to the Micron part MT48LC4M16A2B4-6A IT? I am having trouble figuring it out from the K66 RM. It is a 64Mb SDRAM module organized as 1Mb x 16 x 4 banks. There are 8 column addresses, with 12 address pins and 2 bank select pins. This doesn’t match any of the specific examples in the RM, and I’m not sure I understand it well enough to hook it up right. My best guess would be as follows:
SDRAM Controller Pins: | A9 | A10 | A11 | A12 | A13 | A14 | A15 | A16 | A17 | A18 | A19 | A20 | A21 | A22 |
SDRAM Pins: | A7 | A6 | A5 | A4 | A3 | A2 | A1 | A0 | A8 | A9 | A10 | A11 | BA0 | BA1 |
Is that accurate?”
