Minimum and Maximum Mode of 8086 Compiled by- Mrs Savita C. Raut Minimum and maximum Moode Minimum Mode : Uniprocessor Mode Maximum Mode : Multiple processor mode Some Common Components of 8086 system are: 8284- Clock Generator and driver 8282/8283 – Octal Latch 8286 – Octal bus Transceiver 74138- Decoder 8288- Bus Controller Minimum Mode -8086 Maximum Mode- 8086 8284-Clock Generator & driver Clock requirement of 8086: 8284- Pin diagram Interfacing 8284 with 8086 Cntd.. Interfacing 8284 with 8086 Octal Latch – 8282/8283 Cntd..Octal Latch Internal Diagram of 8282/8283 Bus Transceiver 8286 8286: Pin description Interfacing 8286 with 8086 Decoder-74138 8288- Bus Controller Used in maximum mode configuration of 8086. 8288 accepts the CLK signal along with So ,S1, S2 outputs of 8086 and generates the command , control and timing signals at its output. It also provides the bipolar bus drive capability and optimizes the system performance. 8288 8288 8288 Interfacing 8288 with 8086 Timing Diagrams for 8086 All the operations in 8086 are carried out with a particular sequence in a synchronized manner, so it is necessary to understand the Timing Diagrams. Clock Waveform: It represents the crystal controlled signal sent to 8086 from an external clock generator 8284.
