IO-Link Firmware Update Reference Design Leveraging MSP430 FRAM Technology
Description
IO-Link offers new options for communication between the system control and field level. Today: even the smallest sensors have a powerful microcontroller and several thousand lines of software code. Firmware updates may occasionally be necessary: for example: to fix bugs or to enable new functionalities. This reference design demonstrates the advantages when using a MSP430 microcontroller with FRAM technology for firmware updates with IO-Link instead of using a MCU with flash memory.
Features
- Updating FRAM takes 100x less time and there is no pre-erase requiredData can be written to FRAM on-the-fly right out of the IO-link channel: with no buffering requiredCPU is not held in the process of writes and interrupts are not blockedData will not be lost in case of power failureIP encapsulation module: protect portions of memory from unwanted readsComplies to IO-link specification v1.1 and to IO-link profile BLOB transfer and firmware updates v1.0
