The BR90XX series are serial EEPROMs that can be connected directly to a serial port and can be erased and written

electrically. 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.

Application

General-Purpose

Features

1) BR9010-W / F-W / FV-W / RFV-W / RFVM-W (1k bit) : 64 words×16bit
