FLC-CBM202 Datasheet 4. Physical Interfaces 4.1 WiFi Power Supply 4.1.1 Linear Regulator for Digital Supply A 1.2V LDO in CBM202 powers the core digital circuits and WiFi_VREG_IN_DIG1.8V(Pin17) is the input voltage. The range of this voltage is from 1.45V to 2.0V. WiFi_VDD_DIG (Pin19) is the output of this LDO. A low ESR 2.2uF and a 10nF capacitors to ground should be connected to this pin. 4.1.2 Linear Regulator for Analogue Supply Three 1.
FLC-CBM202 Datasheet 4.3.1 WiFi reset Via the external RST# pin (pin 5) Via an internal core power supply supervisor Using software watchdog timers Via SDIO/CSPI host interface RST# is an active-low reset input that is internally filtered using the internal low frequency clock oscillator to avoid spurious resets. A reset occurs after the signal has been asserted for between 250 and 375 s.
FLC-CBM202 Datasheet 4.5 Host Interface 4.5.1 WiFi Host Interfaces The WiFi of FLC-CBM202 has a single host interface port that can be configured into one of four modes: SD 1-bit SD 4-bit SDIO SPI CSPI The first three modes operate according to the SD Card specifications. The fourth mode is a CSR proprietary variant designed to allow more efficient implementation on hosts without dedicated SDIO host controller. Table 3 shows the usage of the host interfaces pins in each mode.
FLC-CBM202 Datasheet 4.5.1.1.1 SDIO Sleep Signaling FLC-CBM202 supports a variety of mechanisms to enable both itself and the host to efficiently enter and leave low-power modes. 4.5.1.1.1.1 Card Sleep and Wake-up FLC-CBM202 automatically uses its sleep modes to minimize power consumption. Registers in function 0 are always directly accessible by the host, irrespective of the device’s sleep modes. Attempts to access function 1 while the device is in deep sleep are likely to results in SDIO timeouts.
FLC-CBM202 Datasheet The same pin assignments are used for both SD SPI and CSPI as summarized in Table 4. Both the SDIO protocols and CSPI provide access to the same functions and registers within the device; the only difference is with the format of the commands used to perform these accesses. 4.5.2 Bluetooth UART Host Interfaces CBM202 BT UART interface provides a simple mechanism for communicating with other serial devices using the RS-232 protocol.
FLC-CBM202 Datasheet Hardware on the CBM202 for sending data to and from a SCO connection. Up to 3 SCO connections on the PCM interface at any one time. PCM interface master, generating PCM_SYNC and PCM_CLK. PCM interface slave, accepting externally generated PCM_SYNC and PCM_CLK. Various clock formats including: Long Frame Sync Short Frame Sync GCI timing environments 13-bit or 16-bit linear, 8-bit μ-law or A-law commanded sample formats.
FLC-CBM202 Datasheet Generating these signals by DDS from CBM202 internal 4MHz clock. Using this mode limits PCM_CLK to 128, 256 or 512 kHz and PCM_SYNC to 8 kHz. Generating these signals by DDS from an internal 48MHz clock (which enables a greater range of frequencies to be generated with low jitter but consumes more power). To select this second method set bit 48M_PCM_CLK_GEN_EN in PSKEY_PCM_CONFIG32.

FLC-CBM202 Datasheet 8. Recommended PCB Layout and Mounting Pattern Placement and PCB layout are critical to optimize the performances of a module without on-board antenna designs. The trace from the antenna port of the module to an external antenna should be 50 and must be as short as possible to avoid any interference into the transceiver of the module. The location of the external antenna and RF-IN port of the module should be kept away from any noise sources and digital traces.
FLC-CBM202 Datasheet Distance between connection and ground area on the top layer should at least be as large as the dielectric thickness. Routing the RF close to digital sections of the system board should be avoided. To reduce signal reflections, sharp angles in the routing of the micro strip line should be avoided. Chamfers or fillets are preferred for rectangular routing; 45-degree routing is preferred over Manhattan style 90-degree routing.
