FLC-BTM101 Datasheet 4. Physical Interfaces 4.1 Power Supply BTM101 contains two regulators: One switch-mode regulator, which generates the main supply rail directly from battery One low-voltage linear regulator with 1.2V output powers digital circuits VDD_PIO is input voltage to power all digital I/Os including PIOs, UART port, SPI port and I2C. 4.2 Reset The module may be reset from several sources: Power-on reset Software configured watchdog timer. 4.2.

They are all powered from VDD_PIO. PIO lines are software configurable as weak pull-up, weak pull-down, strong pull-up or strong pulldown.
FLC-BTM101 Datasheet 5. Serial Interfaces 5.1 UART This is a standard UART interface for communicating with other serial devices. The UART interface provides a simple mechanism for communicating with other serial devices using the RS232 protocol. When the module is connected to another digital device, UART_RX and UART_TX transfer data between the two devices. When selected in firmware PIO[0] is assigned to UART_TX and PIO[1] is assigned to UART_RX.
FLC-BTM101 Datasheet Figure 3: Example of an I2C Interface EEPROM Connection 5.3 SPI Master Interface BTM101 provides a SPI interface to connect an external serial flash memory. The SPI master memory interface in the BTM101 is overlaid on the I2C interface and uses a further 3 PIOs for the extra pins, see Table 6.
FLC-BTM101 Datasheet Figure 4: Memory Boot-up Sequence 5.4 Programming and Debug Interface The BTM101 debug SPI interface is available in SPI slave mode to enable an external MCU to program and control the BTM101, generally via libraries or tools supplied by Flaircomm.
FLC-BTM101 Datasheet protocol of this interface is proprietary. The 4 SPI debug lines directly support this function. The SPI programs, configures and debugs the BTM101. Take SPI_PIO#_SEL high to enable the SPI debug feature on PIO [8:5]. BTM101 uses a 16-bit data and 16-bit address programming and debug interface. Transactions occur when the internal processor is running or is stopped. Data is written or read one word at a time, or the auto-increment feature is available for block access. 5.4.
FLC-BTM101 Datasheet Do not connect the BTM101 in a multi-slave arrangement by simple parallel connection of slave MISO lines. When BTM101 is deselected (DEBUG_CS# = 1), the DEBUG_MISO line does not float. Instead, BTM101 outputs 0 if the processor is running or 1 if it is stopped.

The data here is given only for guidance on solder reflow. ℃ 250 217 210 A 25 0 B 1 2 C 3 D 4 E 5 6 min Figure 10: Recommended Reflow Profile Pre-heat zone (A) — This zone raises the temperature at a controlled rate, typically 0.5 – 2 C/s. The purpose of this zone is to preheat the PCB board and components to 120 ~ 150 C.
FLC-BTM101 Datasheet intermetallic growth which can result in a brittle joint. The recommended peak temperature (Tp) is 230 ~ 250 C. The soldering time should be 30 to 90 second when the temperature is above 217 C. Cooling Zone (E) — The cooling ate should be fast, to keep the solder grains small which will give a longerlasting joint. Typical cooling rate should be 4 C.
