How to connect to external SRAM by SEMC interface of RT1052?

[954041796]

Dear,

As we known, the SEMC interface of rt1052 supports to access SRAM memory. Here we have a chip operated by setting SRAM, which is adv212 and the rt1052 act as the host. The following is the adv212’s operation sequence diagram, we notice that it has the ACK signal, but the rt1052 only has SEMC_RDY pin. Whether the SEMC_RDY pin is the actual ACK pin, can we connect the SEMC_RDY pin of rt1052 to the adv212’s ACK pin? If no, which one can connect to the ACK pin?

ADV212 Write operation,

ADV212 Read operation,

Best regards!

Hi guanghui he ,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
Firstly, SEMC_RDY pin is used as the CS function pin in SRAM mode.
In further, the 24.4.9 SRAM Controller Operations illustrates the different of SRAM operations, however, they're incompatible with the ADV212 operation, so I'd like to suggest you use the FlexIO module to connect the ADV212, as the FlexIO is able to emulate of a variety of complicated serial/parallel communication protocols. You can learn more information about the module in the RM.
Have a great day,
TIC
