uMMC Electrical Characteristics

Absolute Maximum Ratings

Operating Temperature -55°C to +125°C
Storage Temperature -65°C to +150°C
Voltage on any pin -0.5V to Vcc+0.5V
Maximum Operating Voltage 6.0V

WARNING: Exceeding values beyond these absolute maximum values may cause permanent damage to the device and/or card! Operating at absolute maximum rating conditions for extended periods may affect device and/or card reliability.

  1. Because card active and idle current values vary widely from brand to brand, a maximum cannot be determined. Please refer to your card manufacturers specifications for read/write current consumption values. ↩ ↩2 ↩3

  2. This is the maximum current that the on-board LDO regulator will supply. Cards that require more power than this are not supported. ↩

  3. “Max” means the highest value where the pin is guaranteed to be read as low. ↩

  4. “Min” means the lowest value where the pin is guaranteed to be read as high. ↩
