7.2 DC Characteristics

Table 7-1. DC Characteristics – All InterfacesApplicable over the recommended operating range from TA = -40°C to +125°C, VCC = +2.7V to +5.5V.
Parameters Test Conditions Symbol Min. Typ. Max. Units Type(1)
Supply Voltage on Pin VCC — VCC 2.7 — 5.5 V A
Supply Current on Pin VCC Active mode(4) IIO_Active — 25 40 mA A
Idle mode(2) (TA = +85°C) IIO_Idle — — 10 mA B
Sleep mode IIO_Sleep — 7 15 uA B
VCC Rise Rate — VRISE — — 0.1 V/µs C
High-Level Input Voltage — VIH 0.7 x VCC — VCC + 0.3 V A
Low-Level Input Voltage — VIL -0.3 — 0.3 x VCC V A
Theta JA — ϴJA — 73 — ℃/W 8-Pin SOIC
41.3 24-pad VQFN
Note:
  1. Type means: A = 100% tested, B = characterized, C = design parameter
  2. Idle means that power is applied, the device is NOT in Sleep mode and no commands nor instructions are running.
  3. The state of the VCC latches will be retained so long as VCC remains above the VPOR level.
  4. Active current is measured with all GPIO pins either driven to ground or configured as inputs. Active current also excludes any DC load on the I/O pins.

Table 7-2. DC Characteristics – SPI Interface, RESET and GPIO PinsApplicable over the recommended operating range from TA = -40°C to +125°C, VCC = +2.7V to +5.5V.
Parameters Test Conditions Symbol Min. Typ. Max. Units Type(1)
Input Current(2) 0.1VCC < Vi < 0.9VCC IL -2 — +2 µA A
Programmable Pull-Up — RPU 24k 40k 62k Ω A
High-Level Output Voltage IOH = -4 mA VOH VCC – 0.4 — — V A
Low-Level Output Voltage IOL = 4 mA VOL — — 0.4 V A
Note:
  1. Type means: A = 100% tested
  2. This specification is only valid when the internal pull-ups are disabled. Otherwise, the input current is determined by the internal pull-up resistance value RPU.

Note:
  1. Type means: A = 100% tested, B = characterized on samples
  2. The input current specification is only valid when the internal pull-ups are disabled. Otherwise, the input current is determined by the internal pull-up resistance value RPU.
