In computing, firmware is software that provides low-level control of computer hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionalit

…erase blocks (as small as one byte) and a long lifetime (typically 1,000,000 cycles). Many past microcontrollers included both (flash memory for the firmware and a small EEPROM for parameters), though the trend with modern microcontrollers is to emulate EEPROM using flash. As of 2020, flash memory costs much…
Firmware is commonly stored in an EEPROM or Flash memory, which makes use of an I/O protocol such as SPI.
