CC3100/CC3200 embedded systems contain a serial flash component to store firmware, configuration files and user data for usage by an MCU. The processor sporadically writes data into this serial flash for updating the contents. Inclusion of serial flash memory poses unique challenges for the system designer
- A typical serial flash guarantees a data endurance of 100K write cycles per sector and 20 years data retention. The write endurance and data retention characteristics must to be taken into account by the application developer
- The serial nature of reads and writes results in long access times and this raises the challenge of maintaining a stable system supply voltage for the duration of the access.
This CC3100 & CC3200 Serial Flash Guide provides guidelines and recommendations for system designers working with CC3100/CC3200 file system.
