2. Power Interface
2.1. Power Supply
The host device must provide power to the MC7354B mini card over pins 2, 24, 39, 41 and 52 (VCC)
as detailed in the following table.
Table 1. Power Supply Requirements
Signal
Name
Pin Specification Minimum Typical Maximum Unit
VCC 2, 24, 39, 41, 52
Voltage range 3.0 3.3 3.6 V
Ripple voltage - - 100 mVpp
GND
4, 9, 15, 18, 21,
26, 27, 29, 34, 35,
37, 40, 43, 50
- - 0 - V
Note: The host must provide safe and continuous power at all times; the module does not have an
independent power supply, or protection circuits to guard against electrical issues.
2.2. Electrostatic Discharge (ESD)
The OEM is responsible for ensuring that the Mini Card host interface pins are not exposed to ESD
during handling or normal operation.
Note: The level of protection required depends on your application.
