Hello,
I'm plannning to use the TMS320C5515 with a non-mobile SDRAM( MT48LC4M16A2 1Mx16x4banks)
and notice the following disclamer in the TMS320C5515 data sheet.
External Memory Interface (EMIF)
Note: The device can support non-mobile SDRAM under certain circumstances. The device also always
uses mobile SDRAM initialization, but it is able to support SDRAM memories that ignore the BA0 and BA1
pins for the 'load mode register' command. During the mobile SDRAM initialization, the device issues the
'load mode register' initialization command to two different addresses that differ in only the BA0 and BA1
address bits. These registers are the Extended Mode register and the Mode register. The Extended mode
register exists only in mSDRAM and not in non-mSDRAM. If a non-mobile SDRAM memory ignores bits
BA0 and BA1, the second loaded register value overwrites the first, leaving the desired value in the Mode
register and the non-mobile SDRAM will work with the device.
Based on my interpretation of what the TMS320C5515's data sheet disclamer said I looked on page 42 of the MT48LC4M16A2
1Mx16x4 data sheet.
Since I do not see the BA0 and BA1 in the Mode Register I’m thinking that this should work in my design.
Would you confirm my suspicions?
thanks...
