Damage to the board or host PC may also result. POWER The M52221DEMO utilizes 2 separate voltage rails. The regulator at VR1 energizes the +3.3V rail and provides power to the target MCU and all on-board logic. The regulator at VR2 ener- gizes the +5V rail and provides power the OTG USB bus when the board is configured for host mode applications. -

ON - Input power source connected to +3.3V rail POWER SELECT Two option headers control input power configuration for the M52221DEMO. The PWR_SEL header selects between the on-board, +3.3V, regulator and the USB BDM voltage input. The VX_EN header connects J1-1 directly to the +3.3V rail. The sections below show the different configuration for each option header. -

IIC interface. USB OTG The M52221DEMO features an integrated USB On-the Go (OTG) physical layer (Phy) inter- face. The OTG Phy connects to an MAB connector at J2. Two option headers at DPPD and DMPD provide pull-down configuration for host mode if needed. Installing or removing both jumpers manually controls pull-down configuration. -

Axiom Manufacturing Support CD. ACCELEROMETER The M52221DEMO applies an MMA7260Q, 3-axis accelerometer for tilt and motion-sense ap- plications. The accelerometer supports 4 user selectable sensitivities - 1.5g / 2g / 4g / 6g. The SLEEP* input allows the device to be placed in a low-power mode. Separate (X/Y/Z) axis readings are routed to the MCU An option header at ACC_EN allows the user to disconnect the accelerometer if necessary. -
