• Points to note regarding the MB90F568, 567, and 568 specifications
This section describes the specification differences between the MB90F568/567/568 and the MB90F562/F562B/
562/562A/561/561A.
(1) Functional differences
1) The 5 V to 3 V regulator has been removed in the MB96565 series.
The C pin has been changed to an N.C. pin.
2) The A/D converter unit in the MB96565 series has changed from a 5 V version to a 3 V version.
However, the conversion time and sampling time remain the same.
3) The maximum voltage that can be applied to I/O pins has changed from 5 V to 3 V in the MB96565 series.
4) Added transfer counter clear function to UART in the MB96565 series.
This function restores the UART to its initial state when “0” is written to the UART reset bit.
(2) Points to note when using the devices
The MB90F562, F562B, and F568 use P60 (14) as SIN1, P61 (15) as SOT1, and P40 (60) as SCK0 when
performing on-board programming.
Use the following pin settings when performing on-board programming.

* : These settings are for using a Yokogawa Digital Computer Corporation writer for on-board programming. Alter-
natively, writing can be performed from a PC, but a special write program is required.
