The MC68360 Quad Integrated Communication Controller (QUICC™) is a versatile one-chip integrated microprocessor and peripheral combination family that can be used in a variety of controller applications.

The MC68360 particularly excels in communications activities. The QUICC can be described as a next-generation MC68302, with higher performance in all areas of device operation, increased flexibility, and higher integration. The term "quad" comes from the fact that there are four serial communications controllers (SCCs) on the device. However, there are actually seven serial channels which include four SCCs, two serial management controllers (SMCs), and one serial peripheral interface (SPI).

Host controlled setup

Required equipment:

  • +5 V 5 A power supply
  • +12 V 1 A power supply (optional)
  • Host Computer, one of the following:
    • Sun - 4 (SBus interface)
    • IBM-PC/XT/AT
  • ADI board - compatible with the host computer
  • 37 line flat cable with female 37 pin D-type connectors on each end

Stand alone setup

Required equipment:

  • +5 V 5 A power supply
  • +12 V 1 A power supply (optional)
  • VT100 compatible terminal
  • RS-232 cable with male 9 pin D-type connector on the QUADS side.


BDM controller

The slave QUICC enables the M68360QUADS to become BDM controller to control other QUICC devices on the user application. The BDM feature enables the user to download code and provides hardware and software debugging capability of the user application. The 8 pin BDM connector P9 utilizes five pins of the slave QUICC port B. These pins are configured as general purpose I/O pins.

Ethernet controller

The slave QUICC provides Ethernet port for the M68360QUADS by connecting SCC1 to Motorola MC68160 EEST device (U35 in sheet 10). The MC68160 provides two Ethernet interfaces, twisted-pair on P8 and AUI on P7. The LEDs LD3-LD8 are controlled by the EEST, and they provide indications about the status of the Ethernet ports activity. The signals between the slave QUICC and the MC68160 appear on connector P10 for debugging purposes. P10 is a set of wire holes. The socket U24 is installed for internal factory testing only. For proper operation of the EEST, this socket must be empty.= References =
