PVG valve power supply ratings

DOUT/PVGpwr pins can provide the battery supply voltage required by Danfoss PVG valve electronics for
those control strategies requiring application software control of the valve power source.
When enabled, the DOUT/PVGpwr pin passes battery (reference) voltage to the PVG valve electronics.
One DOUT/PVGpwr pin can power up to 3 PVG valves. Refer to individual module API documents for PVG
power pin characteristics.

FRAM memory

Write/erase cycles
Description
FRAM write/erase cycles
FRAM used in the MC0XX-1XX controller, is rated for 100 trillion read/write cycles per sector. Sector size is
32 bits. When a value is written to FRAM, all 32 bits in a particular sector are always written, regardless of
the size of the saved value. If the value being saved in a sector is less than 32 bits (such as. U8, S16, BOOL,
etc) adjacent bits in the same FRAM sector are rewritten with their previous value. The implication of this
memory property is that if two values are being written to the same memory sector, the useful life of the
sector is determined by the value being written most frequently. If that value exceeds 100 trillion read/
write cycles, all values in the sector may be compromised if the useful life is exceeded.

Vault memory

Some variants of PLUS+1 ® modules have 2 Mbyte of serial flash vault memory (also referred to as
application logging memory).
Application developers can use this memory to log machine event data and use the PLUS+1
to extract the logged data. As there is no real time clock on PLUS+1
stamped.
Accessing non-volatile or application log memory can delay the service tool scan.
