Frequently asked questions
Does the 4K EEPROM share the same endurance and write-cycle rating as the 256KB main FLASH?
On the LPC1549 the 4K EEPROM region is emulated in FLASH sectors — it is not a discrete EEPROM die. The endurance and data-retention characteristics follow the FLASH endurance specification, not a standalone EEPROM spec, which matters for data-logging designs that write frequently to the parameter storage area.
What does the -40°C to 105°C rating mean for enclosed-panel placement?
The 105°C ambient rating exceeds the 85°C ceiling common on standard industrial MCUs, which reduces the thermal derating constraint in sealed enclosures or panels near heat sources. For a 72MHz ARM Cortex-M3 running at full clock with USB and CAN active, the actual junction temperature and PCB thermal design still govern — the ambient rating confirms headroom exists, but a thermal analysis of the specific board layout is the final call.
