With its small form factor and extremely low power consumption, the LS-WIFI8688 is perfect for mobile wireless applications such as asset monitoring, GPS tracking, and battery sensors. The WiFl module incorporates a 2.4-GHz radio, processor, TCP/IP stack, crypto accelerator, power management, and analog sensor interfaces. The module is preloaded with software to simplify integration and minimize application development. In the simplest configuration, the hardware requires only four connections (PWR, TX, RX, and GND) to create a wireless data connection. Additionally, the sensor interface provides temperature, audio, motion, acceleration, and other analog data without requiring additional hardware. The module is programmed and controlled with a simple ASCII command language. Once the module is set up, it can scan to find an access point, associate, authenticate, and connect over any Wi-Fi network. 2.2 Overview ■ Host data rate up to 1 Mbps for the UART ‐ 2 ‐ / 16 ■ Intelligent, built-in power management with programmable wakeup ■ Real-time clock for time stamping, auto-sleep, and auto-wakeup ■ Configuration over UART using simple ASCII commands ■ Remote configuration over WiFi using Telnet ■ Supports over the air firmware upgrade (FTP) ■ Supports WPS pushbutton mode for easy association with access points ■ Secure WiFi authentication using WEP-128, WPA-PSK (TKIP), or WPA2-PSK (AES) ■ Built-in networking applications—DHCP, UDP, DNS, ARP, ICMP, TCP, HTTP client, and FTP client ■ 802.11 power saving and roaming functions ■The modules size: Size: 32mm x 17.5 mm x 3.0 mm 3 Electrical characteristics 3.1 DC/RF CHARACTERISTICS 3.11 Characteristics for IEEE802.11 b 3 / 16 3.12 Characteristics for IEEE802.11g 3.2 Environmental Conditions Parameter WiFi 8688 Temperature Range(Operating) -20°C to +70°C Temperature Range(Storage) -40°C to +85°C Relative Humidity(Operating) ≤90% Relative Humidity(Storage) ≤90% 4 / 16 3.3 Absolute maximum ratings Parameter Minimum Maximum Unit VDD33 -0.3 3.9V V GND - 0 V I/O pin voltage -0.3 VDD33+0.3V V 3.4 Operating conditions Symbol Parameter min Nominal Max Unit VDD33 Supply voltage 3.1 3.3 3.6 V VIH I/O input high voltage 2.3 - Vdd33+0.3 V VIL I/O input low voltage -0.3 - 1.1 V VOH I/O output high voltage 2.57 - - V VOL I/O output low voltage - - 0.4 V 4 Pin-out and signal description 4.1 Pin Pads(Top View): 5 / 16 4.2 Pin Description: No. Terminal Name Type System Connection to IC Terminal Description 1 GND G - VSS Ground 2 NC - - 3 UART_SIN I/O - UART SIN input When not used, this pin should be left floating. 4 UART_SOUT I/O - UART SOUT outpup When not used, this pin should be left floating. 5 NC - - 6 GND G - VSS Ground 7 VDD33 VDD33 - VDD33 3.3V Power Supply 8 GND G - VSS Ground 9 SPI_CLK_REQ/ SD_DAT[3] I/O WLAN SPI_CLK_REQ/ SD_DAT[3] G-SPI Mode: SPI_CLK_REQ G-SPI Clock Request SDIO 4-bit Mode: SD_DAT[3] Data Line Bit[3] SDIO 1-bit Mode: SD_DAT[3] Reserved SDIO SPI Mode: SD_DAT[3] Card Select (active low) 10 SPI_SINTn/ SD_DAT[2] I/O WLAN SPI_SINTn/ SD_DAT[2] G-SPI Mode: SPI_SINTn G-SPI Interrupt Output (active low) SDIO 4-bit Mode: SD_DAT[2] Data Line Bit[2] or Read Wait (optional) SDIO 1-bit Mode: SD_DAT[2] Read Wait (optional) SDIO SPI Mode: SD_DAT[2] Reserved 6 / 16 11 SPI_SDO/ SD_DAT[1] I/O WLAN SPI_SDO/ SD_DAT[1] G-SPI Mode: SPI_SDO G-SPI Data Output SDIO 4-bit Mode: SD_DAT[1] Data Line Bit[1] SDIO 1-bit Mode: SD_DAT[1] Interrupt SDIO SPI Mode: SD_DAT[1] Reserved 12 SPI_SCSn/ SD_DAT[0] IO WLAN SPI_SCSn/ SD_DAT[0] G-SPI Mode: SPI_SCSn G-SPI Chip Select input (active low) SDIO 4-bit Mode: SD_DAT[0] Data Line Bit[0] SDIO 1-bit Mode: SD_DAT[0] Data Line SDIO SPI Mode: SD_DAT[0] Data Output 13 SPI_SDI/ SD_CMD I/O WLAN SPI_SDI/ SD_CMD G-SPI Mode: SPI_SDI G-SPI Data Input SDIO 4-bit Mode: SD_CMD Command/Response SDIO 1-bit Mode: SD_CMD Command Line SDIO SPI Mode: SD_CMD Data Input 14 SPI_CLK/ SD_CLK I WLAN SPI_CLK/ SD_CLK G-SPI Mode: SPI_CLK G-SPI Clock Input SDIO 4-bit Mode: SD_CLK Clock Input SDIO 1-bit Mode: SD_CLK Clock Input SDIO SPI Mode: SD_CLK Clock Input 15 SLEEP_CLK I WLAN SLEEP_CLK Clock Input for External Sleep Clock 16 RESETn I - RESETn Reset (active low) 17 GND G - VSS Ground 18 GND G - VSS Ground 19 GND G - VSS Ground 20 GND G - VSS Ground 7 / 16 5 Functional description 5.1 Functional block diagram 5.2 RF descriptions The LS8688 is equipped with a fully integrated RF to baseband transceiver that operates in both the 2.4 GHz ISM radio band for 802.11g/b WLAN applications, It contains all the circuitry to support both transmit and receive operations. 5.3 On-board antenna specification The LS8688 contains a chip multilayer antenna.
