The BR93LC46-W series are CMOS serial input / output-type memory circuits (EEPROMs) that can be programmed electrically. Each is configured of 64 words × 16 bits (1,024 bits), and each word can be accessed individually and data read from it and written to it. Operation control is performed using five types of commands.
●The commands, addresses, and data are input through the DI pin under the control of the CS and SK pins. In a write operation, the internal status signal (READY or BUSY) can be output from the DO pin.
●Features
●1) 64 words × 16 bits EEPROM
●2) Operating voltage range
● When reading : 2.0 to 5.5V
● When writing : 2.7 to 5.5V
●3) Low current consumption
● Operating (at 5V) : 3mA (Max.)
● Standby (at 5V) : 5µA (Max.)
●4) Address can be incremented automatically during read operations.
●5) Auto erase and auto complete functions can be used during write operations.
●6) A write instruction inhibit function allows :
● - write protection when power supply voltage is low.
● - write disable state at power up.
● - writing using command codes.
●7) Compact packages
●8) Display of READY / BUSY status
●9) TTL-compatible input / output
●10) Rewriting possible up to 100,000 times
●11) Data can be stored for ten years without corruption.
●Applications
● VCRs, TVs, printers, car stereos, cordless telephones, short wave radios, programmable DIP switches, and
●other battery-powered equipment requiring low voltage and low current
