UPD6708 Datasheet Protocol Control Lsi

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD6708 IEBus™ (Inter Equipment Bus™) PROTOCOL CONTROL.

General Description

The µPD6708 is a peripheral LSI for microcontrollers that controls the protocol of the IEBus.

This LSI processes the protocol of the IEBus.

Because it is provided with a transmit/receive buffer, the microcontroller can concentrate on the application processing of the IEBus.

Key Features

  • Protocol control of IEBus.
  • Multi-master system.
  • Broadcast communication function (communication between one unit and multiple units).
  • Choice of three modes with different transmission speeds At 12 MHz Mode 0 Mode 1 Mode 2 Approx. 3.9 Kbps Approx. 17 Kbps Approx. 26 Kbps At 12.58 MHz Approx. 4.1 Kbps Approx. 18 Kbps Approx. 27 Kbps.
  • On-chip IEBus driver/receiver.
  • Transmit/receive buffer Transmit: 4-byte FIFO Receive: 20-byte FIFO.
  • I.
