4.1 RCM3900 Inputs and Outputs
Figure 5 shows the RCM3900 pinouts for headers J61 and J62.
Figure 5. RCM3900 Pinouts
The
RCM3300/RCM3305/
pinouts for the RCM3000, RCM3100, RCM3200,
RCM3309/
RCM3365/RCM3375, and RCM3900
RCM3319, RCM3360/RCM3370,
are almost compati-
ble, except signals PB0, PC4, and PC5. are used for the SPI interface to the serial flash on the
RCM3305/
RCM3309/RCM3315/RCM3319 and for the microSD™ Card on the RCM3900/
, but are available on the other modules.
RCM3910
Headers J61 and J62 are standard 2 × 17 headers with a nominal 2 mm pitch. An RJ-45
Ethernet port is also included with the RCM3900.
Pins 29–32 on header J61 are configured using 0 resistors at locations JP9, JP10, JP7,
and JP8 to enable connections to PD2, PD3, PD6, and PD7 respectively. Note that there is
no 0 resistor at location JP9 since PD2/TPO– is not available on header J61. They may
also be reconfigured to carry the Ethernet signals TPO–, TPO+, TPI–, and TPI+, but this
capability is reserved for future use.
Pins 33 and 34 on header J61 are wired via 0 surface-mount resistors at JP2 and JP3 to
carry the
ACT
and
LINK
signals that illuminate the corresponding LEDs on the RCM3900
module. These pins may be “configured” to carry PD0 and PD1, an option that is reserved
for future use.
See Appendix A.6 for more information about the locations of these headers.
