Technical Note
●Description
BR93L□□-W Series, BR93A□□-WM Series are serial EEPROM of serial 3-line interface method
●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
