MB90560/565 Series
• Standard configuration for Fujitsu standard serial on-board programming
Fujitsu standard serial on-board programming uses a flash microcontroller writer from Yokogawa Digital Com-
puter Corporation (AF220, AF210, AF120, or AF210) .

• Pins used for Fujitsu standard serial on-board programming
Symbol
Pin name
Function
MD2,
Setting MD2 = 1, MD1 = 1, and MD0 = 0 selects serial programming
mode.
Mode input pins
MD1, MD0
X0, X1
As flash memory serial programming mode uses the PLL clock with the
multiplier set to 1 as the internal CPU operation clock, the internal op-
eration clock frequency is the same as the oscillation clock frequency.
Accordingly, the frequency that can be input to the high speed oscilla-
tion input pin when performing serial programming is between 1 MHz
and 16 MHz.
Oscillation input pin
Write program activation
pins
P00, P01
Input P00 = “L” level and P01 = “H” level.
RST
Reset input pin
SIN1
SOT1
SCK0
Serial data input pin
Serial data output pin
Serial clock input pin
Uses UART0 and UART1 in clock synchronous mode. In programming
mode, the pins used by UART0 in clock synchronous mode are SIN1,
SOT1, and SCK0.
Capacitor/power supply in- Capacitor pin for power supply stabilization. Connect an external ce-
C
put pin
ramic capacitor of approx. 0.1 µF.
If the user system provides the programming voltage (MB90F562 :
5 V ± 10%, MB90F568 : 3 V ± 10%) , these do not need to be connected
to the flash microcontroller writer.
VCC

Power supply input pins
GND pin
Connect to common GND with the flash microcontroller writer.
