External Flash
The ATBTLC1000ZR Xplained Pro provides a footprint for an external flash (U101). By default the flash is
connected to the SPI Master/Slave interface of the ATBTLC1000-ZR110CA module, which is also
connected to the Xplained Pro extension header.
The SPI Flash master interface of the ATBTLC1000ZR XPRO can also be used to control the external
flash by reconfiguring the jumper straps (J110-J117) as provided in the following configurations.
External flash Configuration 1:
Short straps J110, J112, J115, and J117
Open straps J111, J113, J114, and J116
External flash Configuration 2:
Short straps J111, J113, J114, and J116
Open straps J110, J112, J115, and J117

Temperature Sensor
The ATBTLC1000ZR Xplained Pro extension board features an AT30TSE758A temperature sensor with
an 8 KB serial EEPROM inside. The sensor includes programmable high and low temperature alarms,
user-selectable temperature resolution up to 12 bits, and an I
