Description
The BR9040 is a serial EEPROM that can be connected directly to a serial port. It can be erased and written electrically, and the writing and reading are performed in word units using four types of operation commands. The communication occurs through CS, SK, DI, and DO pins, while the WC pin control is used to initiate a write-disabled state, enabling these EEPROMs to be used as one-time ROMs. During writing, operation is checked via the internal status check.
