Writing and reading is perfomed in word units, using four types of operation commands. Communication occurs through CS, SK, DI, and DO pins, 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. zApplication General-Purpose zFeatures 1) BR9010-W / F-W / FV-W / RFV-W / RFVM-W (1k bit) : 64 words×16bit BR9020-W / F-W / FV-W / RFV-W / RFVM-W (2k bit) : 128words×16bit BR9040-W / F-W / FV-W / RFV-W / RFVM-W (4k bit) : 256words×16bit 2) Single power supply. 3) Serial data I/O. 4) Self-timed programming cycle with auto-erase. 5) Low supply current.
