5.3.1. External Flash
ATBTLC1000 Xplained Pro provides a footprint for an external flash (U103), the design is tested with an
ISSI IS25LD020-JNLE 2Mb flash. By default the flash is connected to the SPI Master/Slave interface of
the ATBTLC1000 module, which is also connected to the Xplained Pro extension header.
The SPI Flash master interface of the ATBTLC1000 can also be used to control the external flash by
reconfiguring the jumper straps (J109-J112) as below.
External flash Configuration 1: ATBTLC1000 SPI0 peripheral connected (default)
Short straps J109, J110, J111, and J112
Open straps J113, J114, J115, and J116
External flash Configuration 2: ATBTLC1000 SPI flash peripheral connected
Short straps J113, J114, J115, and J116
Open straps J109, J110, J111, and J112
Refer to Design Documentation and the ATBTLC1000-MR110CA datasheet for further reference.

5.3.2. Temperature Sensor
The ATBTLC1000 Xplained Pro extension board features an Atmel AT30TSE758 temperature sensor with
an 8kb serial EEPROM inside. The sensor includes programmable high and low temperature alarms,
user-selectable temperature resolution up to 12 bits, and an I
