Bluetooth® adaptive power management mechanism Linux Support Kernel : 2.6.24 ~ 4.15.17 Supported for Windows 7, 8, 8.1 and 10 RoHS, REACH and WEEE Compliant Solution ## **Overview** The LM813 Series Combination Module supports both WiFi 802.11ac with data rates up to 433Mbps and Bluetooth® 4.2. USB Interface module with added terminals for enabling GPIO’s and Bluetooth Functions to enable coexistence. This IPEX, module operates under 2.4GHz or 5Ghz. LM813 is compliant to IEEE 802.11ac/ a/b/g/n, and Bluetooth® v2.1, v3.0 and v4.2 standards. Currently Bluetooth® includes EDR transmission and supports bandwidths up to 2Mbps, or in HS Mode up to 3Mbps. Upgrading the PCB material to -40°C rated components and using a high quality -40°C low temperature crystal. The main IC from Realtek is only rated at 0°C Our temperature testing is conducted up to -40°C and the module has achieved good results. Although the testing period is only subject to a 72h test period, we have run previous modules using the same brand of BOM material in longer periods of temperature testing. These tests are continuous and enable us to support for -20°C Operating and -30°C Storage Temperature under our own 24 month warranty, from date of dispatch. We have added a heat resistant coating to the bottom of the module enabling higher temperature protection during the re-flow processing in production. +44 (0) 207 428 2647 www.lm-technologies.com/contact Page 2 of 13 ## **LM813 WiFi and Dual Mode Bluetooth® Combination Module** Host Controller Interface (HCI) via USB Interface ## |**General Specification**|| |---|---| |Wireless|| |Wireless Standard|WiFi:| ||802.11 a/b/g/n/ac| ||Bluetooth®:| ||v2.1+EDR/v3.0+HS/v4.0/4.2| |Module Type|Host Controller Interface (HCI)| |OS Compatibility|Linux, and Windows versions to be confirmed.| |Security|WiFi;| ||WPA, WPA-PSK, WPA2,| ||Bluetooth®;| ||Simple Paring| |Network Architecture|WiFi;| ||Ad hoc mode (Peer-to-Peer) and Infrastructure mode Software AP; WiFi Direct| ||Bluetooth®;| ||Pico Net; Scatter Net, Low Power Mode(Sniff Mode)| |Hardware|| |Chipset|Realtek Chipset| |Antenna|Single IPEX Connector| |Interfaces|USB 2.0| ## Block Diagram **==> picture [406 x 207] intentionally omitted <==** **----- Start of picture text -----**<br> TX/RX (2.4G / BT)<br>USB Realtek DPX IPEX<br>Interface Chipset<br>TX/RX (5G)<br>XTAL 40Mhz<br>**----- End of picture text -----**<br> +44 (0) 207 428 2647 www.lm-technologies.com/contact Page 3 of 13 ## **LM813 WiFi and Dual Mode Bluetooth® Combination Module** Host Controller Interface (HCI) via USB Interface ## ## RF Characteristics Range (in open space) WiFi: Up to 180m Bluetooth®: Up to 10m Data Transfer Rate WiFi: 802.11b: 1, 2, 5.5, 11Mbps; 802.11g: 6, 9, 12, 18, 24, 36, 48, 433Mbps; 802.11n MCS0 to 7 for HT20MHz, MCS0 to 7 for HT40MHz Bluetooth®: Basic Rate 1Mbps; Enhanced Rate 2, 3Mbps; High Speed 6, 9, 12, 18, 24, 36, 48, 54Mbps Frequency 2.4GHz and 5GHz ISM Band Modulation Scheme WiFi: CCK, DQPSK, DBPSK, BPSK, QPSK,16QAM, 64QAM, 256QAM Bluetooth®: 8DPSK, π/4 DQPSK, GFSKFSK |Spread Spectrum|WiFi:| |---|---| ||IEEE 802.11b: CCK (Complementary Code Keying)| ||IEEE 802.11g/n/a/ac:OFDM (Orthogonal Frequency Division Multiplexing)| ||Bluetooth®:| ||FHSS (Frequency Hopping Spread Spectrum)| |Antenna|IPEX Antenna x 2| |Security|WPA, WPA2| |RF Output Power (tolerance ± 2dBm)|WiFi| ||17dBm – 802.11b@CCK 11Mbps| ||15dBm – 802.11g@OFDM 54Mbps| ||13dBm – 802.11n@MCS7_HT20| ||13dBm – 802.11n@MCS7_HT40| ||13dBm – 802.11a@OFDM 54Mbps| ||9dBm – 802.11ac@NSS1 MCS9_BW20, BW40, BW80| ||Bluetooth| ||Max + 8dBm| +44 (0) 207 428 2647 www.lm-technologies.com/contact Page 4 of 13 ## **LM813 WiFi and Dual Mode Bluetooth® Combination Module** Host Controller Interface (HCI) via USB Interface |Receiver Sensitivity|WiFi| |---|---| ||-80dBm – 802.11b@11Mbps| ||-71dBm – 802.11g@54MBps| ||-67dBm – 802.11n@MCS7_BW20| ||-64dBm – 802.11n@MCS7_BW40| ||-57dBm – 802.11ac@NSS1_MCS9_BW20| ||-54dBm – 802.11ac@NSS1_MCS9_BW40| ||-51dBm – 802.11ac@NSS1_MCS9_BW80| ||Bluetooth| ||-89dBm@1Mbps| ||-90dBm@2Mbps| ||-83dBm@3Mbps| |Operating Temperature|-20°C to +85°C ambient temperature 0 to 95 % (non-condensing)| |Storage Temperature|-30°C to +95°C ambient temperature 0 to 95 % (non-condensing)| |Dimensions (L x W x H)|25mm x 12mm x 2.05mm| |Weight|0.82 g| |Certifications|See our website for certifications| |Compliance|RoHS, REACH and WEEE| ## **Power Consumption** |**Power Consumption**||| |---|---|---| |DC power for 5V|Performance|| |Description|Typ|Units| |Off|10|uA| |Unassociated idle|40|mA| |Associated idle for 2.4GHz band|70|mA| |Data transfer for 2.4GHz|103|mA| |DC power for 3.3V|Performance|| |---|---|---| |Description|Typ|Units| |Off|16|uA| |Unassociated idle|90|mA| |Associated idle for 2.4GHz band|141|mA| |Data transfer for 2.4GHz|168|mA| Note: Data transfer test using the Linux driver: Linux_v4.3.6_11841.20140714 Note: Data transfer test using the Linux driver: Linux_v4.3.6_11841.20140714 +44 (0) 207 428 2647 www.lm-technologies.com/contact Page 5 of 13 ## **LM813 WiFi and Dual Mode Bluetooth® Combination Module** Host Controller Interface (HCI) via USB Interface ## **Pin Outs** **==> picture [149 x 74] intentionally omitted <==** **----- Start of picture text -----**<br> 9 1<br>8 10 14<br>7<br>19 15<br>6<br>**----- End of picture text -----**<br> ## **Pin Assignments** |Pin|Signal|Type|Description| |---|---|---|---| |1|BT_LED|Output|BT LED Pin(Active Low)| |2|VDD|Power|3.3V or 5V by factory option| |3|HSDM|I/O|High-Speed USB D- Signal| |4|HSDP|I/O|High-Speed USB D+ Signal| |5|GND||Ground| |6|WL_LED|I/O|WLAN LED Pin(Active Low), General Purpose Input/ Output Pin| |7|GND||Ground| |8|RFIO_OUT|RF|WLAN(2.4G/5G)/BT RF port (if don’t using IPEX connector)| |9|GND||Ground| |10|BT_WAKE_HOST|Output|Signal from module to wake up host,refer driver source code for details.| |11|GPIO2|I/O|General Purpose Input/ Output Pin| |12|CHIP_EN|Input|This Pin Can externally shut down the RTL8821CU-CG(No Extra Power Switch Required).| |13|GPIO1|I/O|General Purpose Input/ Output Pin| |14|BT_DIS|Input|Shared with GPIO11.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
