1.2 Comparing the RCM3900/RCM3910 and RCM3365/RCM3375
We can no longer obtain certain components for the RCM3365/RCM3375 RabbitCore
modules that support the originally specified -40°C to +70°C temperature range. Instead of
changing the design of the RCM3365/RCM3375 RabbitCore modules to handle available
components specified for the original temperature range, we decided to develop a new
product line — the RCM3900 series.
The RCM3900 series of RabbitCore modules is similar in form, dimensions, and function
to the RCM3365/RCM3375 modules. We strongly recommend that existing RCM3365/
3375 customers and designers of new systems consider using the new RCM3900 series
RabbitCore modules.
This section compares the two lines of RabbitCore modules.

Temperature Specifications
tured after May, 2008, are specified to operate at 0°C to +70°C. The RCM3900/
RCM3910, rated for -20°C to +85°C, are offered to customers requiring a larger
temperature range after May, 2008.
Removable Mass Storage
device with up to 128MB of memory has been replaced with the miniSD Card with up
to 1GB of memory. The miniSD Card is more readily available today, and is expected
to remain readily available for a long time. In addition, miniSD Cards provide a signif-
icantly larger memory capacity, which has been requested by customers. The trade-off
for the larger memory capacity is that the data transfer rate to/from the miniSD Card is
about an order of magnitude slower than to/from the
Serial Ports
nous serial port on the RCM3365/RCM3375, is used by the RCM3900/RCM3910 as a
clocked serial peripheral interface (SPI) for the miniSD™ Card, and is not brought out
for customer use.
General-Purpose I/O
used to enable/disable the RabbitNet SPI interface when the RCM3365/RCM3375 is
installed on the Prototyping Board. The RCM3900/RCM3900 use PD2 to detect
whether the miniSD™ Card is installed, and so PD2 is not brought out for customer use
on the RCM3900/RCM3910.
