It is intended to replace it in the near future. The reason of this evolution is mainly triggered by the fact that E-Mlx needs a parallel port that is disappearing in the new coming PC generations. Differences with E-Mlx Removed functionalities • Not anymore able to mimic old Crash Barrier E5 emulator. • 3 programmable power supplies instead of 4 Use Vbat for the fourth one . • Programmable power supplies limited to 100mA output current No fan . Changed functionality • PC connection through a USB interface USB compatible • No need for power supply for digital MUST Added functionalities • Enhanced MMF processor Transparent to user but run faster with less code . • Support of real time debugging introduced in MICE for MelexCM. • Flash programming through LIN layer and LIN protocol • Flash programming through LIN layer and Melexis Fast LIN protocol • Flexible connection to a remote hardware for conformance test for example . IMPORTANT: Due to the lightly different use of Mini-EMlx compared to E-Mlx MM, the pinning of Mini-Din 9 is slightly different: Pin Name 1 GND 2 TI0 3 VOUT0 4 LINMUST 5 TI1 6 VBAT 7 VOUT1 8 TO 9 VOUT2 Mini E-Mlx Description Ground Digital MUST output LSB Programmable supply 0 LIN or analog MUST output Digital MUST output MSB Car battery Input Programmable supply 1 Test Output of D.U.T Programmable supply 2 Name GND EXTRA1 VOUT0 MUST EXTRA2 VOUT3 VOUT1 MICE VOUT2 Old E-Mlx MM Description Ground Free N open drain Programmable supply 0 Analog MUST output Free N open drain Programmable supply 3 Programmable supply 1 Test output Programmable supply 2 The main difference is that there are now only 3 programmable supplies instead of E-Mlx MM VOUT3 is now removed and replaced by a VBAT. If Mini E-Mlx is used for pure digital exchanges i.e. Test inputs are MUST digital , there is no need to connect this pin. If analog MUST, LIN, Fast LIN or any VOUT is used, a VBAT 12V must be provided to Mini E-Mlx. Page 4 of 15 Mini E-MLX Hardware Description Other differences Although E-Mlx MM was designed to interface analog MUST pin, it was possible to use NMOS open drain outputs EXTRA1 and EXTRA2 to mimic analog MUST in a digital form. The typical schematic used on the evaluation board for such ICs was as shown on Figure Programmable supply E-Mlx MM Vdd From board or Emulator |
