EC32Lxx Datasheet Introduction WiSmart™ is a versatile, self-contained ultra-low power embedded Wi-Fi modules family for adding Wi-Fi functionality to any existing or new electronic device, sensor, meter or appliance. The EC32Lxx modules are surface mounted WiSmart™ is small in size, high performance design, with models based on the STM32F1x, STM32F2x and STM32F4x families of low power, high performance 32-bit MCUs, combined with the smallest and lowest power consumption Wi-Fi chip in the market. There are three series of WiSmart™ modules differentiating between them on the MCU assembled in the modules. Baseline models:  EC32L11 using STM32F103RD Cortex M3 MCU  EC32L12 using STM32F103RE Cortex M3 MCU  EC32L13 using STM32F103RF Cortex M3 MCU  EC32L14 using STM32F103RG Cortex M3 MCU Advanced models:  EC32L22 using STM32F205RE Cortex M3 MCU  EC32L23 using STM32F205RF Cortex M3 MCU and  EC32L24 using STM32F205RG Cortex M3 MCU High Performance model:  EC32L44 using STM32F405RG Cortex M4 MCU All the models are pin-to-pin compatible, exporting the same HW interfaces. The performance of the exported HW interfaces differs between the models. Please refer to Chapter 8.1 for details on each the available MCU and their HW interface characteristics for the EC32Lxx modules. The EC32L13 Baseline model is the most commonly used, covering most of the IoT and M2M applications. WiSmart™ modules run a powerful software stack provided as library which includes:         TCP-IP stack supporting UDP/TCP sockets, both RAW and BSD format The kernel of ChibiOS RTOS (GNU licensed) Wi-Fi driver Wi-Fi management engine WPA/WPA2 supplicant SSL/HTTPS RTC based Power Management Engine Many free Source Code applications demonstrating the way to add custom application code on top of the provided library. The default WiSmart™ library provides out-of-the-box supports Wi-Fi Ad-Hoc, Wi-Fi client, Wi-Fi AP modes f operation and WPS with Push-Button and PIN options. Customer can make use of the well-defined API exported by the module in order to achieve short REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 5 Introduction WiSmart™ EC32Lxx Datasheet time to market and very short learning curve. There is plenty of FLASH memory left free for any customer application to be developed and run in the module MCU. The RAM/FLASH footprint of the library varies depending to included features. Depending on the application it is possible to provide for entry level models a library with minimal functions. The customer applications (i.e. for reading data from a HW interface and sending them to network) will need only a couple of kilobytes space as almost everything is in the library and the custom code will need just to make calls to the ECONAIS library functions or to STM library functions. WiSmart™ platform and family of products is the ideal development platform for wireless application like but not limited to:           Thermostats Wi-Fi enabled sensors (i.e. CO2 sensors) Smart Meters (Electrical Smart Grid applications), Gas Meters, Water Flow meters Remote Control units, Garage door open system Security/Surveillance (Motion Detector, Fire alarms, Area monitoring) Air-condition units and white appliances Lighting control Building automation Automotive applications Wi-Fi audio solutions REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 6 Introduction WiSmart™ EC32Lxx Datasheet 1.1 Features The following table describes in details the available features.

Typical indoor REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 7 Introduction WiSmart™ EC32Lxx Datasheet range with the chip antenna is between 25m and 50m. When used external antenna, its central frequency should be 2.450 to 2.500 GHz, the bandwidth should be 100MHz, the VSWR should be 1.92 to 2 max and the impedance should be 50 Ohm REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 8 Recommended Operation & Storage Conditions WiSmart™ EC32Lxx Datasheet 2 Recommended Operation & Storage Conditions Table 1 shows the recommended temperature range of temperature for storage and operation of the WiSmart™ modules. Rating Min Max Storage Temperature -50 Operating Temperature -30 Unit +125 °C +85 °C Table 1: Recommended operation & storage conditions NOTE:   If WiSmart™ EC32Lxx will be operated only at -28oC to -30oC range the recommended voltage supply is 3.6V in order to maintain the maximum range. If in this temperature range (-28oC to -30oC) the supply voltage is 3.3V, the range of WiSmart™ is expected to be degraded by a couple of meters. WiSmart™ functionality and network performance is not affected by the voltage or the temperature. If WiSmart™ EC32Lxx will be operated at different temperatures in the range of -30oC to +85 oC the recommended voltage supply is 3.3V. If the device is stored in conditions outside recommended Storage Temperature range it might be damaged. If the device is operated in temperature ranges exceeding the Operating Temperature rage, it might stop performing as designed or stop working. RF output power is expected to degrade up to -2dB as the device temperature closes the limits of the Operating Temperature range. The normal device operation is expected to be resumed as soon as the device returns within the recommended Operating Temperature range. REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 9 Power Supply 3 WiSmart™ EC32Lxx Datasheet Power Supply WiSmart™ typical power supply is 3.3V. For very low temperatures the voltage must be increased. For operation at -30oC the supply voltage should be 3.6V. Power should be supplied to WiSmart™ pins 3, 50 and 51. Please refer to pin assignment table on page 16. Maximum current (peak) for 3.3V power supply using internal clock at 64MHz and having all peripherals enabled iis 282.5mA Maximum current (peak) for 3.3V power supply, using external clock at 72MHz and all peripherals enabled is or 289.5mA.

Item Center Frequency Channel Min Max Unit 2412 2484 MHz 1 14 Channel Numbers Table 5: Channels and frequencies 4.4 Supported Wi-Fi operating modes and features WiSmart™ modules support the Wi-Fi modes of operation and Wi-Fi features as shown in Table 6. Wi-Fi feature Modes of operation Supported mode/feature Client (STA), AP, Ad-Hoc, Description Wi-Fi client (STA mode): WiSmart™ joins and connects to an existing network. In this Wi-Fi network there is a managing device (i.e. an AP or a Wi-Fi router). The AP or Wi-Fi Route is controlling the access of the devices to the Wi-Fi network and the flow of data is through the AP or Wi-Fi router. There is full Wi-Fi power save support for this mode and the power consumption is dramatically decreased. AP mode: In this mode the WiSmart™ becomes the AP and manages the Wi-Fi network. Other devices can connect directly to WiSmart as they would with any other Wi-Fi AP or router. There is full Wi-Fi power save support in this mode. The WiSmart acting as AP need to transmit beacon frames (Wi-Fi management packets) in order for another device to detect it and attempt to connect to it. This increases slightly the WiSmart™ power consumption in this mode comparing to Wi-Fi client mode. WiSmart™ controls the data flow in this mode. Ad-Hoc: WiSmart™ connects directly with other Wi-Fi devices in a peer-to-peer Wi-Fi network without any Wi-Fi network management from any of the participating devices. This is legacy direct device connection. In Ad-Hoc mode there is no Wi-Fi power save feature available for Wi-Fi devices thus the power consumption is increased.

This pin should be connected to the voltage regulator (if any) supplying pins 50 & 51 of the module. The SHUTDOWN pin is active low, so it should be set high during normal operation. Pulling the SHUTDOWN pin low sets Wi-Fi chip in Shutdown mode. This turns OFF most parts of the circuit and minimizes the current consumption. All I/O interface pins are set to predefined states (high, low or high-z) when in Shutdown mode. IT IS STRONGLY RECOMMENDED TO LEAVE THE SHUTDOWN FUNCTION TO BE CONTROLLED BY libwismart AND USE ONLY THE PROVIDED libwismart API TO TURN ON/OFF THE Wi-Fi REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 14 WiSmart™ EC32Lxx pad Assignments 7 WiSmart™ EC32Lxx Datasheet WiSmart™ EC32Lxx pad Assignments EC32Lxx is a surface mounted module.

Table 13: interfaces and resources for EC32L44 models REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 19 Available Interfaces WiSmart™ EC32Lxx Datasheet IMPORTANT NOTE: HW interfaces of the MCU, multiplexed with the SDIO signals (which are used for the communication between MCU and Wi-Fi chip) must not be used. 8.2 Universal synchronous/asynchronous receiver transmitters (USARTs) The available universal synchronous/asynchronous receiver transmitters provide asynchronous communication. They support IrDA SIR ENDEC, multiprocessor communication mode, single-wire half-duplex communication mode and have LIN Master/Slave capability. Some of the USARTs also provide hardware management of the CTS and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication capability. All can be served by the DMA controller. Please refer to MCU Datasheet for details on HW interfaces. 8.3 I2C Bus There are two available I²C bus interfaces for the EC32Lxx able to operate in multi-master and slave modes. I2C supports standard and fast modes, 7/10-bit addressing mode and 7-bit dual addressing mode (as slave). A hardware CRC generation/verification is embedded. I2C can be served by DMA and supports SMBus 2.0/PMBus. 8.4 Serial Peripheral Interface (SPI) There are three SPIs able to communicate in slave and master modes in full-duplex and simplex communication modes. The 3-bit prescaler gives 8 master mode frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification supports basic SD Card/MMC modes. All SPIs can be served by the DMA controller. 8.5 Inter-integrated sound (I2S) There are two standard I2S interface (multiplexed with SPI interfaces), that can be operated in master or slave mode. These interfaces can be configured to operate with 16/32 bit resolution, as input or output channels. When either or both of the I2S interfaces is/are configured in master mode, the master clock can be output to the external DAC/CODEC at 256 times the sampling frequency. 8.6 Controller area network (CAN) The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and 14 scalable filter REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 20 Available Interfaces WiSmart™ EC32Lxx Datasheet banks. 8.7 Universal Serial Bus (USB) The EC32Lxx family embed a USB device peripheral compatible with the USB full-speed 12 Mbit/s. The USB interface implements a full-speed (12 Mbit/s) function interface. It has softwareconfigurable endpoint setting and suspend/resume support. The dedicated 48 MHz clock is generated from the internal main PLL (the clock source must use a HSE crystal oscillator). 8.8 GPIOs (General Purpose Inputs/Outputs) Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current-capable except for analog inputs. The I/Os alternate function configuration can be locked if needed following a specific sequence in order to avoid spurious writing to the I/Os registers. 8.9 ADC (Analog to Digital Converter) Three 12-bit analog-to-digital converters are embedded into WiSmart™ EC32Lxx, and each ADC shares up to 16 external channels, performing conversions in single-shot or scan modes. In scan mode, automatic conversion is performed on a selected group of analog inputs. Additional logic functions embedded in the ADC interface allow:  Simultaneous sample and hold  Interleaved sample and hold  Single shunt The ADC can be served by the DMA controller. An analog watchdog feature allows very precise monitoring of the converted voltage of one, some or all selected channels. An interrupt is generated when the converted voltage is outside the programmed thresholds. The events generated by the general-purpose timers (TIMx) and the advanced-control timers (TIM1 and TIM8) can be internally connected to the ADC start trigger and injection trigger, respectively, to allow the application to synchronize A/D conversion and timers. 8.10 DAC (Digital to Analog Converter) The two 12-bit buffered DAC channels can be used to convert two digital signals into two analog voltage signal outputs. The chosen design structure is composed of integrated resistor strings and an amplifier in inverting configuration. This dual digital Interface supports the following features:   two DAC converters: one for each output channel 8-bit or 12-bit monotonic output REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 21 Available Interfaces WiSmart™ EC32Lxx Datasheet  left or right data alignment in 12-bit mode  synchronized update capability  noise-wave generation  triangular-wave generation  dual DAC channel independent or simultaneous conversions  DMA capability for each channel  external triggers for conversion  input voltage reference VREF+ The DAC channels are triggered through the timer update outputs that are also connected to different DMA channels. 8.11 Temperature Sensor The temperature sensor has to generate a voltage that varies linearly with temperature. The conversion range is between 2V < VDDA < 3.6V. The temperature sensor is internally connected to the ADC1_IN16 input channel which is used to convert the sensor output voltage into a digital value. 8.12 JTAG The ARM SWJ-DP Interface is embedded, and is a combined JTAG and serial wire debug port that enables either a serial wire debug or a JTAG probe to be connected to the target. The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP. REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 22 Other Features 9 WiSmart™ EC32Lxx Datasheet Other Features 9.1 Nested vectored interrupt controller (NVIC) The EC32Lxx family embeds a nested vectored interrupt controller able to handle up to 60 maskable interrupt channels (not including the 16 interrupt lines of Cortex™-M3) and 16 priority levels.  Closely coupled NVIC gives low latency interrupt processing  Interrupt entry vector table address passed directly to the core  Closely coupled NVIC core interface  Allows early processing of interrupts  Processing of late arriving higher priority interrupts  Support for tail-chaining  Processor state automatically saved  Interrupt entry restored on interrupt exit with no instruction overhead This hardware block provides flexible interrupt management features with minimal interrupt latency. 9.2 External interrupt/event controller (EXTI) The external interrupt/event controller consists of 19 edge detector lines used to generate interrupt/event requests. Each line can be independently configured to select the trigger event (rising edge, falling edge, both) and can be masked independently. A pending register maintains the status of the interrupt requests. The EXTI can detect an external line with a pulse width shorter than the Internal APB2 clock period. All the GPIOs could be connected to the 16 external interrupt lines. 9.3 Clocks and startup System clock selection is done during startup sequence however the internal RC oscillator is selected as default CPU clock on reset. An external clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example with failure of an indirectly used external oscillator). Several prescalers allow the configuration of the AHB frequency, the high speed APB (APB2) and the low speed APB (APB1) domains. Please check the MCU datasheet for the maximum frequency of the AHB, the high speed APB domains, the maximum allowed frequency of the low speed APB domain and for details on the clock tree. 9.4 Boot Modes At startup, boot pins are used to select one of three boot options:  Boot from user Flash: you have an option to boot from any of two memory banks. By REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 23 Other Features WiSmart™ EC32Lxx Datasheet default, boot from Flash memory bank 1 is selected. You can choose to boot from Flash memory bank 2 by setting a bit in the option bytes.  Boot from system memory  Boot from embedded SRAM The boot loader is located in system memory. It is used to reprogram the Flash memory by using USART1. The state of the B0 pin determines the boot memory to be used. 9.5 Power supply schemes    VDDIO = 2.0 to 3.6 V: external power supply for I/Os and the internal regulator. Provided externally through VDD pins. VDD, VDDA = 2.0 to 3.6 V: external analog power supplies for ADC, DAC, Reset blocks, RCs and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC or DAC is used). VDDA and VSSA must be connected to VDD and VSS, respectively. VBAT = 1.8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup registers (through power switch) when VDD is not present. 9.6 Power supply supervisor The device has an integrated power-on reset (POR)/power-down reset (PDR) circuitry. It is always active, and ensures proper operation starting from/down to 2 V. The device remains in reset mode when VDD is below a specified threshold, VPOR/PDR, without the need for an external reset circuit. The device features an embedded programmable voltage detector (PVD) that monitors the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is higher than the VPVD threshold. The interrupt service routine can then generate a warning message and/or put the MCU into a safe state. The PVD is enabled by software. 9.7 Voltage regulator The regulator has three operation modes: main (MR), low power (LPR) and power down.    MR is used in the nominal regulation mode (Run) LPR is used in the Stop modes. Power down is used in Standby mode: the regulator output is in high impedance: the kernel circuitry is powered down, inducing zero consumption (but the contents of the registers and SRAM are lost) This regulator is always enabled after reset. It is disabled in Standby mode. 9.8 DMA The flexible 12-channel general-purpose DMAs (7 channels for DMA1 and 5 channels for DMA2) are able to manage memory-to-memory, peripheral-to-memory and memory-to-peripheral transfers. The two DMA controllers support circular buffer management, removing the need for user code intervention when the controller reaches the end of the buffer. Each channel is connected to dedicated hardware DMA requests, with support for software trigger REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 24 Other Features WiSmart™ EC32Lxx Datasheet on each channel. Configuration is made by software and transfer sizes between source and destination are independent. The DMA can be used with the main peripherals: SPI, I2C, USART, general-purpose, basic and advanced-control timers TIMx, DAC, I2S, SDIO and ADC. 9.9 RTC The RTC and the backup registers are supplied through a switch that takes power either on VDD supply when present or through the VBAT pin. The backup registers are forty-two 16-bit registers used to store 84 bytes of user application data when VDD power is not present. They are not reset by a system or power reset, and they are not reset when the device wakes up from the Standby mode. The real-time clock provides a set of continuously running counters which can be used with suitable software to provide a clock calendar function, and provides an alarm interrupt and a periodic interrupt. It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal low power RC oscillator or the high-speed external clock divided by 128. The internal lowspeed RC has a typical frequency of 40 kHz. The RTC can be calibrated using an external 512 Hz output to compensate for any natural quartz deviation. The RTC features a 32-bit programmable counter for long term measurement using the Compare register to generate an alarm. A 20-bit prescaler is used for the time base clock and is by default configured to generate a time base of 1 second from a clock at 32.768 kHz. IMPORTANT NOTE: The RTC cannot be used by customer application. Customer application should use the timers API provided by ECONAIS library 9.10 Timers and watchdogs The EC32Lxx family includes up to two advanced-control timers, up to four general-purpose timers, two basic timers, two watchdog timers and a SysTick timer. The following table compares the features of the advanced-control, general-purpose and basic timers. 9.10.1 High-density timer feature comparison Prescaler factor DMA request generation Capture / Compare channels Complementary outputs 16-bit Up, down, up/down Any integer between 1 and 65536 Yes 4 Yes TIM2, TIM3, TIM4, TIM5 16-bit Up, down, up/down Any integer between 1 and 65536 Yes 4 Yes TIM6, 16-bit Up Any integer Yes 0 No Timer TIM1, TIM8 Counter resolution Counter type REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 25 Other Features WiSmart™ EC32Lxx Datasheet TIM7 between 1 and 65536 Table 14: Timer feature comparison 9.10.2 Advanced-control timers (TIM1 and TIM8) The two advanced-control timers (TIM1 and TIM8) can each be seen as a three-phase PWM multiplexed on 6 channels. They have complementary PWM outputs with programmable inserted dead-times. They can also be seen as a complete general-purpose timer. The 4 independent channels can be used for:  Input capture  Output compare  PWM generation (edge or center-aligned modes)  One-pulse mode output If configured as a standard 16-bit timer, it has the same features as the TIMx timer. If configured as the 16-bit PWM generator, it has full modulation capability (0-100%). In debug mode, the advanced-control timer counter can be frozen and the PWM outputs disabled to turn off any power switch driven by these outputs. Many features are shared with those of the general-purpose TIM timers which have the same architecture. The advanced-control timer can therefore work together with the TIM timers via the Timer Link feature for synchronization or event chaining. 9.10.3 General-purpose timers (TIMx) There are up to 4 synchronizable general-purpose timers (TIM2, TIM3, TIM4 and TIM5) embedded in the EC32Lxx performance line devices. These timers are based on a 16-bit auto-reload up/down counter, a 16-bit prescaler and feature 4 independent channels each for input capture/output compare, PWM or one-pulse mode output. This gives up to 16 input captures / output compares / PWMs on the largest packages. The general-purpose timers can work together with the advanced-control timer via the Timer Link feature for synchronization or event chaining. Their counter can be frozen in debug mode. Any of the general-purpose timers can be used to generate PWM outputs. They all have independent DMA request generation. These timers are capable of handling quadrature (incremental) encoder signals and the digital outputs from 1 to 3 hall-effect sensors. 9.10.3.1 Basic timers TIM6 and TIM7 These timers are mainly used for DAC trigger generation. They can also be used as a generic 16-bit time base. 9.10.3.2 Independent watchdog The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is clocked from an independent 40 kHz internal RC and as it operates independently from the main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog to reset the device REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 26 Other Features WiSmart™ EC32Lxx Datasheet when a problem occurs, or as a free running timer for application timeout management. It is hardware or software configurable through the option bytes. The counter can be frozen in debug mode. 9.10.3.3 Window watchdog The window watchdog is based on a 7-bit down-counter that can be set as free running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the main clock. It has an early warning interrupt capability and the counter can be frozen in debug mode. 9.10.3.4 SysTick timer This timer is dedicated to real-time operating systems, but could also be used as a standard down counter. It features:     A 24-bit down counter Auto-reload capability Maskable system interrupts generation when the counter reaches 0.

REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 36 Power save modes, wake-up times and power consumptionWiSmart™ EC32Lxx Datasheet 17 Power save modes, wake-up times and power consumption All members of WiSmart™ family of modules have implemented advanced algorithms of power save and power management for both MCU and Wi-Fi. The Wi-Fi power save is controlled exclusively by the libwismart library and the customer can only turn ON/OF the total Wi-Fi subsystem. The WiSmart power modes, the wake-up time from each of them and their descriptions are as shown in Table 15. WiSmart Wake-up power mode time Description No power save MCU runs always at full speed. No power save mechanism is used. NO POWER SAVE In this mode the device has very fast reactions and fast threads switching achieving the highest possible performance. CPU and all Peripherals are always on. Wi-Fi connectivity is sustained. Normal level of power save The CPU starts and stops automatically when needed according to the algorithm implemented in the libwismart library. NORMAL POWER SAVE 2 uS All the peripherals are always ON and the only component that is going to sleep mode is the CPU. The device will wake-up from internal or external events/IRQs or the RTC trigger or on incoming Wi-Fi traffic. Wi-Fi connectivity is sustained. High level of power save The CPU starts and stops automatically when needed according to the algorithm implemented in the libwismart library. HIGH POWER SAVE 20 uS Peripherals are disabled and DMA is stopped The device will wake-up only from external IRQs or the RTC trigger or on incoming Wi-Fi traffic. Wi-Fi connectivity is sustained. In this mode RTC cannot used by customer application as Calendar Device not running MCU is stopped and no code is executed. Wi-Fi is powered-off. The device will wake-up and resume operation only from an external IRQs or the RTC module. OFF After wake-up the system is in reset state. This means that the full boot sequence will run including Wi-Fi initialization. After resuming operation the device will restore Wi-Fi and TCP socket connections automatically Wi-Fi connectivity is not sustained. In this mode RTC cannot used by customer application Table 15: MCU power save levels REV.11, 13-May-2014 ©ECONAIS, Proprietary and Confidential 37 Power save modes, wake-up times and power consumptionWiSmart™ EC32Lxx Datasheet Wake-up time is the time from the wake event to the moment of the execution of the first command at the MCU.

Use of encryption or not does not affect power consumption TCP traffic is used which is the case in most of real world applications  An overhead of 10% or even more in lower rates compared to UDP: o In the RX TCP traffic there are also TX packets for acknowledgements o In the TX TCP traffic there are also RX packets for acknowledgements The power consumption is related to throughput. “iperf” is used in the WiSmart™ and on a PC to generate traffic and measure power consumption of complete system (not Wi-Fi only) Figure 9: Power measurement setup Table 14 shows the power consumption of the WiSmart™ with the iperf added to the Serial to WiFi code in the environment described above. All the values in table 14 are in mA. The TCP network traffic expresses the amount of data transmitted or received within the period of one second. The highest possible Wi-Fi link speed is automatically selected by the Wi-Fi chip for every transmission.

There is a known issue with some AP/Routers with specific chipsets in 802.11n mode with which the WiSmart™ has lower performance by about 10%. For these cases is recommended to operate the WiSmart™ in 802.11b/g mode for maximum performance. 2. The VBAT pin of the MCU (pin 10 of the module) is by mistake connected internally to the Wi-Fi VBAT pin (pin 50 of the module). This would prevent the VBAT of the MCU to be supplied when the Wi-Fi part is powered off.
