1 ...the world's most energy friendly microcontrollers EFM G890 MU oard Preliminary The EFM G890 MU oard is a small plugin module for usage with the EFM Gecko evelopment Kit. Features: The worlds most energy friendly microcontroller ompatible with the dvanced Energy Monitoring (EM) system of the EFM Gecko evelopment Kit Leds indicating power and reset MHz crystal.68 khz crystal Reset button and ground-hooks for easy debugging Energy Micro L

2 ...the world's most energy friendly microcontrollers Usage. Placement This board is intended for use with the EFM Gecko evelopment Kit.. Reset utton / Reset LE When pressed, the reset button resets the EFM device. When reset is asserted, a red led next to the button is lit. filter is connected to the reset line in order to reduce bouncing.. LEs Indicating Power The two green LEs indicate poweron the VMU and.v nets, respectively..4 rystal Oscillators The board features one.68khz and one MHz crystal. These are connected through 0-ohm resistors to the respective inputs of the low-frequency and high-frequency crystal oscillators of the EFM. Using these instead of the internal R-oscillators will ensure higher frequency accuracy. However, if the reduced accuracy is acceptable, theese lines can be used as normal IO-lines instead by removing the 0-ohm resistors. In order to export these IO lines to the Kit mainboard, insert resistors for connection to the EFM_ bus. See schematic for details..5 Kit onnection It is possible to access the board controller on the Kit mainboard for example to turn LEs on or off, read push button status or connecting the EMF to specific hardware on the mainboard. The access may either through SPI or the parallel interface (EI), and the access mode is signaled to the board controller by asserting one of two dedicated signal lines. It is recomended to use the oard Support Package (SP) for access to the mainboard. Please see the Kit user guide for furhter description of the SP..6 L The L is a 64 segment display designed for /4 uty, / bias. The operating voltage is.0v and the frame frequency is 64 Hz. Since the EFM only supports 60 segments, the elsius and Fahrenheit along with u and m segments are not connected. However, they may be made available by moving a 0-ohm resistor. See schematic for details. Please see the L software example project for details on how to use the L. For details on segment connections see the attached mapping table and L illustration.. EI / L onfiguration Since many of the IO lines used by the EI are also used by the L, the board is either configured to route the IO lines to the L connector or to the Kit mainboard. The configuration is determined by a set of 0-ohm resistor arrays. This configuration may be altered my moving the arrays. See schematic for details Rev: t000_.00
