Port Pins Deleted

In the TMP92CF30, the following port pins are deleted as opposed to the

TMP92CZ26A/CF26A.

And TMP92CF30 support the external 32bit bus function except for access to SDRAM.

Added: External 32bit bus function added. (However, if an ICE using the TMP92CF26A is

used to development and debugging, it is possible only to operate by 16 bit bus

• Port F: PF3 (I2S1CKO), PF4 (I2S1DO), PF5 (I2SWS)

• Port P: PP7 (TB1OUT0), PP2 (TA5OUT), PP1 (TA3OUT)

• Port U: PU0 to PU7 (LD16 to LD23)

• Port V: PV0, PV1, PV2, PV3, PV4

• Port W: PW0 to PW7

Maximum Memory Size Accessible with the MMU Function Reduced

With the deletion of the P84 (

can be expanded with the MMU function is reduced, resulting in a reduced number of usable

banks. In the TMP92CZ26A/CF26A the total expandable memory size is 3.1 Gbytes, which is

reduced to 2.1 Gbytes in the TMP92CF30. Accordingly, the number of banks in the Z area is

reduced from 512 banks to 256 banks.

If an ICE using the TMP92CF26A is used for development and debugging, be careful

about registers and banks which are available in the TMP92CF26A but do not exist in the

TMP92CF30. For details, see the chapter on the MMU function.
