Product overview
20 EL9800
tween PIC and EtherCAT postage stamp is realized using the SPI-Interface. Additionally an EEPROM
(U1004, Type: AT24C16A) is connected to the PIC using the I²C-Interface. Furthermore a crystal (X1000)
with 24 MHz resonant frequency is also connected with the PIC.
For demonstration and testing purposes digital in- and outputs and an analogue input connected with the
PIC are available. Eight LEDs and eight Switches each are building the digital interface of the PIC( pinout
see Table 9). The analogous input is connected to the Port RB3 of the PIC.
State and error indication is available by the LEDs connected to the ports RF1 (RUN) and RF0 (ERR) of
the PIC.

The connectors TP209 and J209 are connected with the Port of the PICs and can be used as test points
and for interfacing with external hardware. The connectors TP209 and J209 pinout is shown in Table 11.
