8.1. Technical data
Temperature specification
Operating -30 to +70 °C
Storage -40 to +80 °C
Kernel
Main Processor
NXP™ i.MX8 DualXPlus: ARM 64-bit, 1200MHz, Cortex
®
-A35
Co-processor
STMicroelectronics STM32F071VB, Cortex
®
-M0
Data storage 4 Gbyte, Industrial grade eMMC
(Note)
RAM memory 1 Gbyte, LPDDR4
Note: The eMMC is used in pseudo SLC mode and implements both static and dynamic wear levelling to
reach the best reliability. The number of program/erase cycles is between 20k to 60k depending on the
manufactures and temperature. Our recommendation for the application software is to temporary
cache in RAM and to write larger chunks of data to the eMMC. This recommendation is not specific to
eMMC but is applicable to all flash memories.

External fuse recommendation
Current rating
2-3 A* (including maximum external loads)
* This assumes that the fuse is in accordance with IEC 20127 i.e. can be continuously operated at
100% of rated current.
CAN interfaces
Type
Non-isolated, ISO 11898-1, CAN 2.0B with cable shield decoupling
according to J1939-11.
Supports ISOBUS
CAN transceiver NXP TJA1051T/3
Baud Rate
20 – 250 kbps (up to 1 Mbps)*
* Internal CAN bus filters have a capacitance of 100pF (typ) as stated in the J1939 specification. This
puts restrictions on the CAN bus topology considering bus length, number of CAN nodes etc. when
running at bit-rates higher than 250 kbps.
Protection Short circuit protected to -36V to +36V
