3. Terminal Description 3.1 UART Interface This is a standard UART interface for communicating with other serial devices. BCM-DA100-AS UART interface provides a simple mechanism for communicating with other serial devices using the RS-232 protocol. When BCM-DA100-AS is connected to another digital device, UART_RX and UART_TX transfer data between the 2 devices.
3.2 SPI Interface The SPI is capable of communicating with external device. Both 3-wire and 4-wire mode SPI interface are supported. When 3-wire mode is selected, SPI_MOSI would be data I/O pin of the SPI interface. Only master mode supported. The SPI interface is shared with GPIOs and the mapping tables are Listed below.
3.3 I2C Interface The I2C is master interface. It supports 100, 400 and 800Khz clock rates. For controlling EEPROM, A write protect (WP) signal is also supported through GPIO. The I2C interface provides several data formats and can fit various I2C peripherals. Sequential read and write are supported to improve throughputs.
4. Battery Charger 4.1. Battery Charger Hardware Operating Modes The Li-mode battery charger of BCM-DA100-AS provides four modes: ▪ Trickle mode ▪ Constant current mode (CC mode) ▪ Constant voltage mode (CV mode) ▪ Standby mode The below block diagram shows the charge circuit. When an external power supply is connected to AB1122 VCHG pin, PMU will first detect if the VCHG voltage is correct and enable the charger circuit.
WARNING : For BCM-DA100-AS. If you have reflow process multiple times in your product, you must be proceed this module in the final reflow process. If not the Shield can will drop out.
FCC MODULAR APPROVAL INFORMATION EXAMPLES for Manual This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
Validity of using the module certification: In the event that these conditions cannot be met (for example certain laptop configurations or co‐ location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product.
