Hi Please verify the attached Asynchronous Memory interface with microcontroller for 256K x 16 bits part.
As per the Technical refernce manual :
10.2.5.1 Interfacing to Asynchronous Memory
Figure 10-2
shows the EMIF's external pins used in interfacing with an asynchronous device. Of special note
is the connection between the EMIF and the external device's address bus. Because the device uses 32-bit
data paths internally, the EMIF address pin EM_A[0] always provides the least-significant bit of a 32-bit word
address.
When interfacing to an 8-bit asynchronous device, the EM_BA[1] and EM_BA[0] pins are used to provide the
least-significant bits of the byte address.
Figure 10-3
shows the mapping between the EMIF and the connected device's data and address pins.
Kindly verify and let me know is this interface correct with respect to 16bit SRAM interface with microcontroller.(
Little-endian operating mode
)
Regards
Suresh
