Help me interface a static RAM using data bus at 16 bits

INTERFACING RAM *16

hI, I HAVE TO INTTERFACE A STATIC RAM USING A DATA BUS AT 16 BITS.
IS CORRECT THAT I USIGN THIS MAP ?

MICRO SRAM
-----------------------------------------------
A1 ------------------> A0
A2 ------------------> A1
. .

A18 ------------------> A17


tHANKS FOR YOUR REPLIES.

Re: INTERFACING RAM *16

There are several things i dont have clear here, Ax stands for address?

If so, i think u are using one more address pin from the micro that u should, u have from A1 to A18, 18 pins, i thouhgt it was a 16 data bus RAM, one more thing, data bus doen't mean u have to use 16 pins to direction it, it depends on the size of the memopry rather than the data bus, check the address bus for that.

Re: INTERFACING RAM *16

yes sorry, A main Address.
And the data bus is 16 bits wide.

Re: INTERFACING RAM *16

Well, see when u have a micro it can direction some memory, it depends on how many address pins it has, if it has 2 pins it can direcction just 4 addresses 2^2. for more pins more addresses 2`#pin.

Now, u have to build a memory map, that means you have to choose in what range of external componentes the micro con hanlde are u gonna put the ram memory, this will depend on the other external hardware the micro has and the internal memory too, once u have choosen a range of addresses to put your ram, the easier way is to try put it on a range that starts with all 0 for the ram address bus, rg: if the micro has 4 address pins and the ram has 2 addres pins, u can put the ram on the first 2 pins or on the last 2 pins, wheter choice u make the other 2 pins that u are not using are gonna be part of te enable circuitery for the ram memory.

after thaat u just connect the pins from the address bus of the micro to the address bus of the ram....

sorry i extended myself that much,

To answear your question i think the address bus u have selected is ok, with the A0 as your memory enable.

Sorry again for that much text, it seems u already know that.

hope it helped
