I/O Connected Functions
to
I/O MPU
18-bit bi-directional data bus.
8-bit bus interface: DB17-10
9-bit bus interface: DB17-9
16-bit bus interface: DB17-10, 8-1
18-bit bus interface: DB17-0
The pins not used for data transfer must be fixed to Vcc or GND.
Serial data output pin (SDO) to output on the falling edge of SCL
signal in SPI mode.
I/O MPU
18-bit bi-directional data bus.
8-bit bus interface: DB17-10
9-bit bus interface: DB17-9
16-bit bus interface: DB17-10, 8-1
18-bit bus interface: DB17-0
The pins not used for data transfer must be fixed to Vcc or GND.
I/O Oscillation- Connect to an external resistor for R-C oscillation. When
resistor
supplying clocks externally, supply with OSC1, and leave OSC2
open.
I MPU or
Reset pin. Initialize the LSI at low.
Reset
Power-on reset required when turning on the power supply.
generating Supply with either one of RESET1,2,3, and leave the unused pins
circuit
open.
I GND
Test pin. Must be fixed to GND level.
I GND
Test pin. Must be fixed to GND level.
- Power
Logic Vcc: +2.2V ~ +3.3V
supply
Logic-side ground, GND: 0V
- Power
Vcc power supply for internal RAM. Supply same electric potential
supply
as Vcc.
- Power
Analogue-side ground, AGND: 0 V

O Opposing Output GND level.
GND for
Opposing GND for external elements (capacitors, diodes).
external
elements
I Vcc or
Power supply for analogue circuits. Connect to an external power
power
supply of 2.5V ~ 3.3V.
supply
I/O Vcc or
Output internal reference voltage with amplitude between Vci and
power
GND. Reference voltage for step-up circuit1.
supply
Connect to an external power supply of 2.75V or lower, when
internal reference voltage is not used.
I/O Stabilizing Output Vci1 after stepped-up 2~3 times by step-up circuit 1. The
Capacitor or step-up scale is determined with internal register setting. Connect
open
to a stabilizing capacitor. When step-up circuit 1 is not used,
leave open.
I DDVDH or Reference voltage for step-up circuit 2. Connect to DDVDH.
power
Connect to an external power supply of 5.5V or lower, when
supply
DDVDH is not used.
I/O Stabilizing Output voltage with amplitude between VGH and GND after
Capacitor or stepped-up 2~4 times by step-up circuit 2. The step-up scale is
power
determined with internal register setting. Connect to a stabilizing
supply
capacitor. When step-up circuit 2 is not used, connect to an
external power supply of 16.5V or lower.
