High level input voltage
Low level input voltage
SCL, SDA High level input voltage
SCL, SDA Low level input voltage
High level output voltage Iout=-100μA
Low level output voltage Iout=100μA (
SDA Low level output voltage Iout=3mA
Input leak current
Input leak current (pull-down)
Input leak current XTI pin
Note 11. Except for the SCL, SDA pin.
Note 12. Except for the SDA pin.
Note 13. Except for the TESTI pin, XTI pin.
Note 14. The TESTI pin has an internal pull-down device, nominally 150kΩ.
Power supply current (
Note 15. Depends on the system frequency and contents of DSP program.
Note 16. This is a reference value when using a crystal oscillator. Since most of the supply current at the initial reset state
Rev.0.5b_PB
(Ta=-20ºC ~70ºC; AVDD=DVDD=3.0~3.6V)
(Ta=25ºC; AVDD=DVDD=3.0~3.6V(typ=3.3V, max=3.6V))
Normal Operation
Reset (IRESETN= “L” reference data)
AVDD+DVDD
AVDD+DVDD
is in the oscillator section, the value may vary according to the crystal type and the external circuit. This value is
just reference.
