16,00€ Net VAT excluded

RTC option with battery on M7 Cortex CPU. NOT purchased separately, sold only in conjunction with CPU.
This option is produced on demand, so the quantity in stock is usually 0.
Average delivery time is 1 week from order.

This option, installed on ARM Cortex M7 CPUs, adds RTC functionality with battery.
The Cortex M7 Base CPUs do not have RTC working with the system off, so in some cases it may be necessary to install this option.
On the latter, system-off operation is guaranteed by a lithium battery with a minimum life of 5 years with the system off.
The product can NOT be purchased separately, but only in combination with a Cortex M7 CPU (Cod. MPS054**00, MPS056**10, PCB137**00, PCB141**10).
