MKW41Z module  are  fully  integrated  2.4GHz  Bluetooth  Low  Energy  (BLE  4.2)  and  IEEE  802.15.4  compliant transceiver and a powerful 32-bit ARM® Cortex M0+ MCU, up to 512kB flash and 128kB SRAM memory and rich peripherals. The industry standard Micro trace buffer and serial wire SWD programming and debugging interfaces together with the standard ARM system debug components help to streamline any custom software development. Module  has  inbuilt  chip  antenna.  These  antenna  supports  BLE  and  IEEE  802.15.4  protocol  ISM  Band (2.4GHz).  The  voltages  are  monitored  (brown-out  detection)  and  the  built  in  power-on-reset  circuit eliminates  the  need  for  any  external  monitoring  circuitry.  This  module  has  support  of  external  RTC 32/32.768 kHz watch crystal. The MKW41Z512 module have fully integrated DC-DC converter with Buck, Boost and Bypass modes. Module can be easily configured for Buck and Boost mode power operations. For more details please check DCDC converter section.
VT-MKW41Z Module Datasheet  Rev 0.4  Confidential  Copyright © 2017 Volansys   Volansys Technologies  Page | 15 5.2 Antenna The MKW41z Module includes an integrated chip antenna. The MKW41Z Module should be mounted with the PCB chip antenna overhanging the edge of the host board. To further improve performance, a ground plane may be placed on the host board under the module up to the antenna keep out area. The installation of an uninterrupted ground plane on a layer directly beneath the module will also allow you to run traces under this layer. The chip antenna is compact and highly efficient. To maximize range, an adequate ground plane must be provided  on  the  host  PCB.  Correctly  positioned,  the  ground  plane  on  the  host  PCB  will  contribute significantly to the antenna performance; it should not be directly under the chip antenna. The position of  the module on  the  host  board  and overall  design  of  the  product enclosure contribute to  antenna performance.  Poor  design  affects  radiation  patterns  and  can  result  in  reflection,  diffraction  and/or scattering of the transmitted signal. A few design guidelines to help ensure antenna performance: • Never place the ground plane or route copper traces directly underneath the antenna portion of the module • Never place the antenna close to metallic objects • In the overall design, ensure that wiring and other components are not placed near the antenna • Do not place the antenna in a metallic or metalized plastic enclosure • Keep plastic enclosures 1cm or more away from the antenna in any direction 5.3 Module Reset Pin 15 is used as an external reset. The reset pin only contains an active pull down device. This pin can be used for other  functions, such  as  GPIO,  by  setting the  RESET_PIN_CFG option bit of the FTFA_FPORT register to 0. This bit is retained through system resets and low power modes. When the RESET pin is disabled and configured as a GPIO output, it operates as a pseudo open drain output. 5.4 Clock The MKW41z Module requires two clock system.  On module 32MHz crystal used for RF reference oscillator. The clock is used by the RF, analog and digital section interfaces. It can be used also by the MCU core and as a clock source for some internal peripherals. For normal run modes, an internal oscillator can provide the low frequency clock. However, to make full use of reduced power modes an external crystal must be present. The MKW41z Module supports external 32/32.768KHz crystal. This is used as the clock for the RTC and the deep-sleep clock. Symbol Parameter Typ. Max. Unit FNOM_LFXO Crystal frequency 32/32.768 - KHz FTOL_LFXO_BLE Frequency tolerance, BLE applications ±20 ±250 ppm CL_LFXO Load Capacitance 7 12.5 pF Note:  External capacitors are not required for 32KHz crystal.

VDD_1V8 is internal configurable LDO output referred as VDD_1P8OUT.  6.3 DC-DC Converter The MKW41z module contains an integrated DCDC converter which allows for three modes of operation without additional components. When operating in DCDC Buck mode, power consumption from using the radio can be reduced compared to DCDC Bypass mode. DCDC Boost mode allows the use of a single alkaline or other low voltage source. While it is possible to switch between these modes in a single design.
