BR93LC46-W Datasheet PDF - ROHM Semiconductor

●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
