Contact us: sales@integrated-circuit.com Website: www.integrated-circuit.com
The RCM5700 and RCM5750 models already have an Ethernet PHY device, the Integrated Cir-
cuit Systems ICS1893BK. The RCM5710 and RCM5760 are identical to the RCM5700 and
RCM5750 respectively, except that they have an integrated 10/100 Base-T magnetic RJ-45 jack
with two LEDs on the MiniCore printed circuit board.
There are four RCM6700 production models. Table 1-2 summarizes their main features.

The Rabbit 6000 has an Ethernet PHY built into the processor. The RCM6710 and RCM6760 are
identical to the RCM6700 and RCM6750 respectively, except that they have an integrated 10/100
Base-T magnetic RJ-45 jack with two LEDs on the MiniCore printed circuit board.
Placing the RJ-45 Ethernet jack on the motherboard, which is what must be done with the
RCM5700/RCM6700 and RCM5750/RCM6750 models, provides significant design advantages
because the core module may then be placed anywhere on the motherboard. Rabbit's Technical
Note TN266, PCB Layout for the Ethernet PHY Interface, provides complete design recommen-
dations. If the RJ-45 Ethernet jack is on the MiniCore printed circuit board, as it is on the
RCM5710/RCM5760/RCM6710/RCM6760 modules, the edge of the MiniCore module with the
Ethernet jack must be positioned along the edge of the motherboard to allow access to the jack
since the entire assembly will likely be inside a customer-designed enclosure.
