Summary
Flash technology is constantly changing, providing faster program and erase cycles, a bigger number of guaranteed erase and re-program cycles and longer data retention. Flash technology put on-chip with microcontrollers has now reached the point, where the in-application usability greatly improved.
In the past, storing of configuration data that stays available after a power-down and power-up cycle required an additional EEPROM or other storage device. Today, this functionality can be provided by on-chip Flash, further decreasing the parts count of embedded applications: an additional external EEPROM or SRAM might not be required anymore.
