4.5

External memory interface

The following sections provide information about external memory interfaces.

4.5.1

SEMC specifications

The following sections provide information on SEMC interface.

Measurements are with a load of 15 pf and an input slew rate of 1 V/ns.

4.5.1.1

SEMC output timing

There are ASYNC and SYNC modes for SEMC output timing.

4.5.1.1.1

SEMC output timing in ASYNC mode

Table 47 shows SEMC output timing in ASYNC mode.

TAHO

Address output hold time

(TCK - 2) 1

1 Address output hold time is configurable by SEMC_*CR0.AH. AH field setting value is 0x0 in above table. When AH is set

with value N, TAHO min time should be ((N + 1) x TCK). See the i.MX RT1160 Reference Manual (IMXRT1160RM) for more

detail about SEMC_*CR0.AH register field.

TADVL

Active low time

(TCK - 1) 2

2 ADV# low time is configurable by SEMC_*CR0.AS. AS field setting value is 0x0 in above table. When AS is set with value N,

TADL min time should be ((N + 1) x TCK - 1). See the i.MX RT1160 Reference Manual (IMXRT1160RM) for more detail about

SEMC_*CR0.AS register field.

3 Data output hold time is configurable by SEMC_*CR0.WEH. WEH field setting value is 0x0 in above table. When WEH is set

with value N, TDHO min time should be ((N + 1) x TCK). See the i.MX RT1160 Reference Manual (IMXRT1160RM) for more

detail about SEMC_*CR0.WEH register field.
