Figure 6. RCM3365/RCM3375 Pinouts
The pinouts for the RCM3000, RCM3100, RCM3200, RCM3300/RCM3310, RCM3360/
RCM3370, and RCM3365/RCM3375 are almost compatible, except signals PB0, PC4, and PC5.
PB0, PC4, and PC5 are used for the SPI interface to the serial flash on the RCM3300 and the
RCM3310, but are available on the other modules. PB0 on the RCM3365 and the RCM3375 is
used to sense whether the removable xD-Picture Card card is installed. If you need PB0 for other
purposes, you may remove the surface-mount resistor at R96 (Figure A-5 shows the location of
R96).
Headers J3 and J4 are standard 2 × 34 headers with a nominal 2 mm pitch. An RJ-45 Ether-
net port is also included with the RCM3365/RCM3375.
Pins 29–32 on header J3 are configured using 0 Ω resistors at locations JP4, JP5, JP7, and
JP7 to be PD3, PD2, PD7, and PD6 respectively. They may also be reconfigured to carry
the Ethernet signals TPO+, TPO–, TPI+, and TPI–.
Pins 33 and 34 on header J3 are wired to carry the LINK and ACT signals that illuminated
the corresponding LEDs on the RCM3365/RCM3375 module. These signals may be “dis-
connected” by removing 0 Ω surface-mount resistors R41 and R42 (Figure A-5 shows the
locations of R41 and R42).
