(2) DC Characteristics
(Ta = -40°C ~ 85°C; AVDD = DVDD = 3.0~3.6V; DVDD18 = 1.7~2.0V)
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
SDA Low level output voltage Iout=3mA
Input leak current
Input leak current (pull-down)
Input leak current (XTI pin )
Note 15. SCL (I2CSEL=1) and SDA pins are not included. (SCLK pin is included when I2CSEL=0)
Note 16. SDA pin is not included.
Note 17. The pull-down pins and XTI pin are not included.
Note 18. The pull-down pins (Typ150kΩ) are: TESTI1, TESTI2
(3) Current Consumption
(Ta=25°C; AVDD=DVDD=3.0~3.6V(typ=3.3V,max=3.6V); DVDD18=1.7~2.0V(typ=1.8V, max=2.0V))
Power supply
Power supply current
Note 19. Varies slightly according to the system frequency and contents of the DSP program.
Note 20. This is a reference value when using a crystal oscillator.
MS0581-E-00-PB
1)
2) INIT_RESET = “L” (reference)
Low level output voltage Iout=100μA
a) AVDD
b) DVDD
c) DVDD18
Since most of the supply current at the initial reset state is in the oscillator section, the value may vary slightly
according to the crystal type and the external circuit. This is a “reference value” only.
