NXP Semiconductors Freescale MC13892 User Manual

MC13892 Evaluation Board Supports KIT13892VKEVBEJ and KIT13892VLEVBEJ, Rev. 4.06 Freescale SemiconductorIntroductionCommunication voltage selection - This communication board allows the user to select one of the following threecommunication voltages through hardware, which are very common on most of the applications:• 5.0 V - This voltage comes directly from the USB port and can be selected by connecting J3(1-2). Thisselection ignores the voltage coming from the LDO, and sets the USB voltage as the maximum level forcommunication.• 3.3 V - This voltage can be selected by connecting J5(1-2) and J3(2-3).This selection configures theLDO to supply 3.3 V, and set the voltage as the maximum voltage reference of communication.• 1.8 V - This communication voltage is selected by connecting J5(2-3) and J3(2-3). By connecting thesetwo jumpers, the LDO supplies 1.8 V, and set this voltage level as the maximum voltage reference ofcommunication.3.3 EVBs Operating ParametersKIT13892VXEVBEJ Board• Input voltages:• Battery: 3.7 V• USB/Wall charger: 5.0 V• Power supply for backlighting: 9.0 V• Default output voltages:• Regulators: SW1 = 1.05 V; SW2 = 1.22 V; SW3 = 1.2 V; SW4 = 1.8 V; SWBST = 5.0 V (when a charger is attached, otherwise 0 V).• Linear regulators: VUSB = 3.3 V; VUSB2 = 2.6 V; VPLL = 1.8 V; VDIG = 1.25 V; VIOHI = 2.775 V;VGEN1 = 0 V; VGEN2 = 3.15 V; VGEN3 = 0 V; VSD = 0 V; VVIDEO = 0 V; VAUDIO = 0 V; VCAM = 0 V.• Switching frequency in regulators: 3.1457 MHz (SWBST operates at 2.0 MHz).• Communication interfaces:• SPI - Frequency up to 26 MHz• I2C - Frequency at 400 kHz• Power control signals - RESETB, RESETBMCU, WDI, INT, STANDBY, STANDBYSEC, CHRGSE1B, andCSKITUSBCOMDGLEVME Board• Power supply = 5.0 V (supplied by computer USB port)• Communication Interfaces:• I2C - Frequency up to 3.5 MHz (100 kHz, 400 kHz or 3.5 MHz); Voltage Level = Selectable (5.0 V, 3.3 V, or 1.8 V)• SPI - Frequency up to 4.0 MHz; Voltage Level = Selectable (5.0 V, 3.3 V, or 1.8 V)• UART - Frequency from 2400 bps to 115200 bps; Voltage Level = 12 V (Typ.)• USB - Frequency fixed at 12 Mbps; Voltage Level = 5.0 V (Typ.)• Other Signals:• Four PWM signals (Adjustable frequency up to 4.0 MHz)• Open Drain signals with selectable voltage Level (5.0 V, 3.3 V or 1.8 V)• Three GPIOs (General Purpose I/O pins) Open Drain signals with selectable voltage Level (5.0 V, 3.3 V,or 1.8 V)• Two ADCs (10 bits)• Identifiers - Two ADC signals pulled up to 5.0 V thru 10 kohm resistors.
