Serial EEPROM Series Standard EEPROM

SPI BUS EEPROM

BR25Sxxx-W Series

(32K 64K 128K 256K)

●General

Description

BR25Sxxx-W series is a serial EEPROM of SPI BUS interface method

●Features

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

Wait function by HOLDB terminal

Part or whole of memory arrays settable as read only

memory area by program

1.7V to 5.5V single power source action most suitable

for battery use

Page write mode useful for initial value write at

factory shipment

Highly reliable connection by Au pad and Au wire

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

Auto erase and auto end function at data rewrite

Low current consumption

At write action (5V)

: 1.5mA (Typ.)

At read action (5V)

: 1.0mA (Typ.)

At standby action (5V) : 0.1μA (Typ.)

Address auto increment function at read action

Write mistake prevention function

Write prohibition at power on

Write prohibition by command code (WRDI)

Write prohibition by WP pin

Write prohibition block setting by status registers

(BP1, BP0)

Write mistake prevention function at low voltage

Data kept for 40 years

Data rewrite up to 1,000,000 times

Data at shipment

Memory array: FFh

Status register: WPEN, BP1, BP0 : 0
