BR93A46RFJ-WE2 ROHM Memory

BR93A46RFJ-WE2 Overview

The BR93A46RFJ-WE2 is a serial EEPROM, which means it communicates using a serial interface (such as I2C or SPI) and is designed for data storage that can be read, written, and erased electronically. It offers a small storage capacity of 1 Kbit (128 bytes), making it suitable for applications where modest non-volatile memory is needed.

Features

1) 3-line communications of chip select, serial clock, serial data input / output (the case where input and output are shared)

2) Actions available at high speed 2MHz clock(2.5~5.5V)

3) Speed write available (write time 5ms max.）

4) Same package and pin layout from 1Kbit to 16Kbit

5) 1.8~5.5V (BR93L□□-W Series), 2.5～5.5V(BR93A□□-WM Series) single power source action

6) Highly reliable connection by Au pad and Au wire

7) Address auto increment function at read action

8) Write mistake prevention function

Write prohibition at power on

Write prohibition by command code

Write mistake prevention function at low voltage

9) Program cycle auto delete and auto end function

10) Program condition display by READY / BUSY

11) Low current consumption

At write action (at 5V) : 1.2mA (Typ.)

At read action (at 5V) : 0.3mA (Typ.)

At standby action (at 5V) : 0.1μA (Typ.)(CMOS input)

12) TTL compatible( input / output s)

13) Compact package SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J*1

14) Data retention for 40 years

15) Data rewrite up to 1,000,000 times

16) Data at shipment all addresses FFFFh
