High Reliability Series Serial EEPROMs

SPI BUS

BR25□□□□family

BR25S

□□□

Series

●Description

BR25S

□□□

series is a serial EEPROM of SPI BUS interface method.

●Features

1) High speed clock action up to 20MHz (Max.)

2) Wait function by HOLDB terminal

3) Part or whole of memory arrays settable as read only memory area by program

4) 1.7½5.5V single power source action most suitable for battery use

5) Page write mode useful for initial value write at factory shipment

6) Highly reliable connection by Au pad and Au wire

7) For SPI bus interface (CPOL, CPHA) = (0, 0), (1, 1)

8) Auto erase and auto end function at data rewrite

9) Low current consumption

At write action (5V)

: 1.5mA (Typ.)

At read action (5V)

: 1.0mA (Typ.)

At standby action (5V)

: 0.1μA (Typ.)

10) Address auto increment function at read action

11) Write mistake prevention function

Write prohibition at power on

Write prohibition by command code (WRDI)

Write prohibition by WPB pin

Write prohibition block setting by status registers (BP1, BP0)

Write mistake prevention function at low voltage

12) SOP8/SOP-J8/SSOP-B8/TSSOP-B8/MSOP8/TSSOP-B8J/VSON008X2030 Package

13) Data at shipment Memory array: FFh, status register WPEN, BP1, BP0 : 0

14) Data kept for 40 years

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