1.8 Features of MKY02
This section describes the features of the MKY02 HUB-IC for the HLS.
(1) Supports full and half-duplex communication modes.
(2) Supports any baud rates up to 12.5 Mbps, including standard baud rates of 12, 6, and 3 Mbps.
(3) Has a dedicated port (port 0) connecting the center IC and seven ports (ports 1 to 7) connecting satel-
lite ICs.
This can facilitate configuration of a HUB with two to eight ports using one MKY02.
(4) Has output pins that can turn on monitor LEDs when any one or more of the eight ports receive a
packet.
(5) Has output pins for receiving monitor for each port to turn on monitor LEDs when eight ports receive
a packet.
(6) Has output pins that can turn on monitor LEDs when any one or more of the eight ports receive an
error packet.
(7) Has pins for cascade-connection that can add ports.
(8) Can be connected to both 5.0-V and 3.3-V TTL level signals using 5.0-V tolerant signal pins.
(9) Operates on 3.3-V single power supply and available in 0.5 mm pitch, 64 pins, TQFP.
The MKY02 can be used as the CUnet family of HUBs by setting the HC pin (pin 50).
However, HLS and CUnet networks cannot be connected via the HUB. Note that the
MKY02 is not a
“bridge” for connecting networks using different family products.
For details of HUB of the CUnet family, refer to “MKY02 User’s Manual (for CUnet)” .
