  • Page 11: The Jumpers Of The Minicon-535

    Jumper 3. Jumpers of the MC-535 The operating mode of the miniCON-535 is determined by a series of jumpers, which also consider the battery back-up and the selection of the memory. The jumpers are first described individually and then a typical configuration of the jumper-position is shown.
  • Page 12 1, which is not used by the miniCON-535. For EEPROMs with this option, JP5 should be not installed, other- wise the miniCON-535 will not be operating. Using a 32 KByte-RAM this jumper has to be bridged to A14. The installation with a 32 KByte-EPROM requires a jumper to VCC and a connection of A14 to the middle connection of JP4.

    Memory of MC-535 4. The Memory of the MC-535 4.1 Memory Extension The miniCON-535 provides three 28-pin sockets U3, U4, and U5. The positions of the addresses depend on the address decoder. In section 4.2 several configurations are described for some standard decoders.
  • Page 18 Please connect in this case jumpers JP4,JP5 and JP6 to VCC. For the installation of an 32 KByte-EPROM, jumpers JP5 and JP6 have to be connected to VCC. The pin in the middle of JP4 has to be connected to A14 of JP5 (see section 3.2). © PHYTEC Meßtechnik GmbH 1996 L-002-02...

  • Page 31: Application Of The Clock Chip

    9. Application of the Clock-Chip The Real-Time Clock operates with battery back-up independent from the functioning of the miniCON-535. The crystal oscillator is integrated in the chip. A tuning is not necessary. The clock has an interface of 4 bit for the connection to the bus of the processor. Ac- cording to our standard address decoding, it is placed in the region of the data memory.

    This bit can be read only. Access to registers should be executed only if BUSY is low. BUSY is always high, as long as HOLD is not set to high. After activating HOLD, BUSY will be low at the latest of 190 µsec. © PHYTEC Meßtechnik GmbH 1996 L-002-02...

    Usually the removal of the chip or the voltage supply connector, is not bounce free. A minimum rise time of the supply voltage of 10 msec will eliminate problems with the stimulation of oscillation for the system cycle. © PHYTEC Meßtechnik GmbH 1996 L-002-02...
  • Page 36: The Battery Back-Up

    11. The Battery Back-up Battery back-up with a Lithium battery (3V/120mAh) is not manda- tory for the operation of the miniCON-535. Using EEPROMs, battery back-up should be avoided anyway, if the /WE input of the EEPROM has not a high impedance. The RAM-socket of U4 is permanently connected with the supply voltage.

  • Page 45: Special Features Of The Cmos Version Of The 80535

    The following short description is only for completeness and refers only to the controller itself. This concept was not incorporated into the complete functioning of the miniCON-535. - The first difference between SAB80535 and 80C535 exists in the different bit assignment of the register PCON. By setting of two bits in two consequent machine instructions either the power-down- mode or the idle-mode of the controller is activated.
  • Page 46 Thereafter the controller resumes its normal operation. The power consumption of the controller in idle-mode depends on the activity of the internal peripherals. Note: The miniCON-535 was designed for the NMOS version of the 80535 and therefore doesn’t sup- port all possibiities for the reduction of power consumption in idle-mode.
