AP6255 Datasheet 6.2 Recommended Footprint Solder paste layer design is generally the same as recommended footprint. (錫膏層設計通常建議和焊墊尺寸相同) If soldering quality with good wetting on upright side is essential for PQC, how to optimize the aperture design in the stencil to adjust the amount of solder paste would be crucial. In addition, a kind of stencil design with stepped thickness in partial area would be considered if the thickness of stencil is about 0.1mm or thinner.

AP6255 Datasheet 8.2 SDIO Interface Description The module supports SDIO version 3.0 for all 1.8V 4-bit UHSI speeds: SDR50(100 Mbps),SDR104(208MHz) and DDR50(50MHz, dual rates) in addition to the 3.3V default speed(25MHz) and high speed (50 MHz). It has the ability to stop the SDIO clock and map the interrupt signal into a GPIO pin. This ‘out-of-band’ interrupt signal notifies the host when the WLAN device wants to turn on the SDIO interface.

AP6255 Datasheet 8.3 PCM Interface Description The PCM Interface on the BCM43456 can connect to linear PCM Codec devices in master or slave mode. In master mode, the BCM43456 generates the PCM_CLK and PCM_SYNC signals, and in slave mode, these signals are provided by another master on the PCM interface and are inputs to the BCM43456.The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI commands.

AP6255 Datasheet 8.4 UART Interface Description The UART is a standard 4-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates from 9600 bps to 4.0 Mbps. The interface features an automatic baud rate detection capability that returns a baud rate selection. Alternatively, the baud rate may be selected through a vendor-specific UART HCI command. UART has a 1040-byte receive FIFO and a 1040-byte transmit FIFO to support EDR.
