6.7
The power supply for the F2M03GLA should be chosen carefully. Bad power supply can reduce the
performance and may damage the module. Please use the recommended voltage regulator or consult
Free2move if using another regulator. It is also essential to use a proper reset circuit to the module for
correct operation.
6.7.1
The F2M03GLA has one power supply, +VCC.
The voltage supplied should have low noise, less than 10mV rms between 0 and 10MHz. The transient
response of the regulator is also important. At the start of a Bluetooth packet, power consumption will jump
to high levels. The regulator should have a response time of 20µs or less; it is essential that the power rail
recovers quickly.
Recommended voltage regulator:
XC6209B332MR from Torex or TPS73633DBVTG4 from Texas Instrument
6.7.2
The F2M03GLA has an active low reset (pin nr: 30). The reset pin MUST be connected to either a reset-
circuit (voltage monitor) such as the TC1270ASVRCTR, MAX811S, DS1818 or using an I/O from a
microcontroller. Reset cannot be done with a R-C network. It is recommended to used one of the reset
circuits mentioned above. Special considerations must be taken when using an I/O from a microcontroller; a
pull-down resistor (1.8kΩ) must be placed on the I/O-line.
It is recommended that RESET is applied for a period greater than 5ms.
At reset the digital I/O pins are set to inputs for bi-directional pins and outputs are tristated. The PIOs have
weak pull-downs.
