Functional Outline
Quartz crystal oscillator connection (tie to digital ground via a 22pF capacitor)
D
I - 27.00 MHz crystal oscillator should be used
- input from 27.00 MHz crystal oscillator is connected to this pin
Quartz crystal oscillator connection (tie to digital ground via a 22pF capacitor)
- 27.00 MHz crystal oscillator should be used.
D
O - this pin outputs DVSS level when PDN = L.
- when a crystal oscillator is not used, this pin can either be left open (NC) or
connected to DVSS
Clock mode set: connect to either DVDD (high) or DVSS (low)
D
I - Low setting: crystal oscillator is used
- High setting: external clock source is used
Output enable
P
I - L : digital output pins are at high-Z
- H : data is available for output
- Hi-Z input on OE pin is prohibited
I2C data
P
I/O
- this pin is pulled-up to PVDD
- Hi-Z input is allowed when PDN is low
- SDA input is not accepted during reset operation
I2C clock input
P
I
- an input level below PVDD should be input
- Hi-Z input is allowed when PDN is low
- SCL input is not accepted during reset operation
Reset signal input
- Hi-Z input to this pin is prohibited
P
I - L: reset
- H: normal operation
Power-down control
P
I
- Hi-Z input to this pin is prohibited
- L: power-down
- H: normal operation
Data clock for output interface
P
I/O - output state is separately controlled by combinations of RSTN/PDN/OE pin
settings (note 1)
- this pin is used as an I/O pin in test mode
Data output (MSB)
P
I/O - output state is controlled by combinations of RSTN/PDN/OE pin settings (note 1)
- this pin is used as an I/O pin in test mode
