## **LM832 WiFi and Bluetooth® Dual Mode Combi Module** Standalone with SDIO and UART Interfaces Product LM832 Part No See Last Page Revised 13/MAR/2018 Version 1.1 > **Android** ye msa **XP** ## **Features** - WiFi 802.11 b/g/n - e Support sophisticated WiFi/BT coexistence mechanism to enhance collection performance - Support Bluetooth adaptive power management mechanism - SDIO for WiFi and UART (High Speed) for Bluetooth - e IPEX Connector or PCB Antenna options - 19mm x 12mm x 2mm - Full speed Bluetooth® Piconet and Scatternet supported - ° 1T 1R, Supporting 150Mbps Bandwidth e - SMT Side and Bottom Pads for easy production - RoHS, REACH and WEEE ## **Overview** The LM832 module incorporates an intelligent coexistances mechanism for WiFi 802.11 b/g/n via SDIO and Dual Mode Bluetooth® v4.1 via UART. This is ideal for significantly minimising the BoM cost and PCB space. running the application. It also incorporates 4 GPIO pins for interfacing with peripheral devices. The LM832 utilises a powerful Cypress chipset, which enables the LM832 HCI Module to be compatible with the latest Android platform, Linux Kernel v4.3.6 and Android4.4_V2.19. It’s SMT side and bottom pads allow for easy manufacture and placement within your product. **LM832** Page 1 of 15 **+44(0) 207 428 2647 | sales@lm-technologies.com** ## **LM832 WiFi and Bluetooth® Dual Mode Combi Module** ## Standalone with SDIO and UART Interfaces Product LM832 Part No See Last Page ## |**General Specification**|| |---|---| |Wireless|| |Wireless Standard|WiFi:| ||802.11 b/g/n| ||Bluetooth:| ||v2.1+EDR / v3.0 / v4.1| |Module Type|Standalone (Embedded Wireless Stack) or Host Controller Interface (HCI)| |Profiles|TBA| |OS Compatibility|Linux, Android and Windows XP| |Security|WiFi:| ||WEP, WPA Personal, WPA2 Personal, WMM, WMM-PS(U-APSD), WMM-SA, WAPI,| ||AES (Hardware Accelerator), TKIP(host-computed), CKIP(Software Support)| ||Bluetooth;| ||Secure Simple Paring| |Network Architecture|WiFi:| ||Ad hoc mode (Peer-to-Peer), Infrastructure mode, Software AP and WiFi Direct| ||Bluetooth;| ||Piconet; Scatternet| |Hardware|| |Chipset|Cypress| |Antenna|PCB Antenna or IPEX Receptical| |Microcontroller (MCU)|ARM Cortex-M3, with 512 kB on-chip flash| |Flash Memory|8 MB| |RAM|128 kB| |Interfaces|WiFi:| ||SDIO 2.0| ||Bluetooth:| ||UART (Baud rates up to 4 Mbps)| |Power Supply|3V6 (VDDIO) or 4V8 (VBAT)| |Crystal Oscillators|26 MHz and 32.768 kHz (External)| |Development Kit|LM522| **LM832** Page 2 of 15 **+44(0) 207 428 2647 | sales@lm-technologies.com** ## **LM832 WiFi and Bluetooth® Dual Mode Combi Module** ## Standalone with SDIO and UART Interfaces Product LM832 Part No See Last Page ## |RF Characteristics|| |---|---| |Tx Output Power|WiFi:| ||17dBm – 802.11b@11Mbps 15dBm – 802.11g@6Mbps 15dBm –| ||802.11g@54Mbps 13dBm – 802.11n@MCS0_HT20 13dBm –| ||802.11n@MCS7_HT20| ||Bluetooth:| ||Class 1| |Rx Sensitivity|WiFi:| ||-76dBm – 802.11b@11Mbps -65dBm – 802.11g@54MBps| ||-64dBm – 802.11n@MCS7_HT20| ||Bluetooth:| ||-89dBm@1Mbps -90dBm@2Mbps -83dBm@3Mbps| |Data Transfer Rate|WiFi:| ||802.11b: 1, 2, 5.5, 11Mbps; 802.11g: 6, 9, 12, 18, 24, 36, 48, 54Mbps;| ||802.11n MCS0 to 7 for HT20MHz| ||Bluetooth:| ||Basic Rate 1Mbps; Enhanced Rate 2, 3Mbps;| ||High Speed 6, 9, 12, 18, 24, 36, 48, 54Mbps| |Frequency|2.4GHz to 2.4835 GHz| |Modulation Scheme|WiFi:| ||802.11b: CCK, DQPSK, DBPSK 802.11g: 64QAM, 16QAM, QPSK,| ||BPSK 802.11 g/n: 64QAM, 16QAM, QPSK, BPSK| ||Bluetooth:| ||GFSK, π/4 DPSK, 8DPSK| |Spread Spectrum|WiFi:| ||IEEE 802.11b: DSSS (Direct Sequence Spread Spectrum)| ||IEEE 802.11g/n: OFDM (Orthogonal Frequency Division Multiplexing)| ||Bluetooth:| ||FHSS (Frequency Hopping Spread Spectrum)| |Operating Channel|WiFi (2.4GHz):| ||11: (Ch. 1-11) – United States 13: (Ch. 1-13) – Europe| ||14: (Ch. 1-14) – Japan| ||Bluetooth (2.4GHz):| ||Ch. 0 to 78| **LM832** Page 3 of 15 **+44(0) 207 428 2647 | sales@lm-technologies.com** ## **LM832 WiFi and Bluetooth® Dual Mode Combi Module** Standalone with SDIO and UART Interfaces Product LM832 Part No See Last Page ## |Physical Characteristics|| |---|---| |Operating Temperature|-20°C to +60°C ambient temperature 5 to 90 % (non-condensing)| |Storage Temperature|-20°C to +70°C ambient temperature 0 to 95 % (non-condensing)| |Dimensions (L x W x H)|19mm x 12mm x 2mm| |Weight|0.44 g (PCB Antenna Module) and 0.46 g (IPEX Module)| |Certifications|See our website for this products certifications| |Compliance|RoHS, REACH and WEEE| **LM832** Page 4 of 15 **+44(0) 207 428 2647 | sales@lm-technologies.com** ## **LM832 WiFi and Bluetooth® Dual Mode Combi Module** Standalone with SDIO and UART Interfaces Product LM832 Part No See Last Page ## **Antenna Options** RF Type 1: PCB Antenna Module RF Type 2: IPEX Connector Module ## **RF Connector Dimensions** **==> picture [422 x 314] intentionally omitted <==** **----- Start of picture text -----**<br> 2.60±0.10<br>0.25<br>0.60<br>0.10<br>A<br>il tes ,<br>A A<br>MAX<br>0.60 A<br>0.60<br>0.050 A B<br>A ø1.70±0.050 fol TT<br>ø1.00<br>B ø0.50±0.050<br>A.

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.
