DESCRIPTION

· The BR25Lxxx-W series is a serial EEPROM utilizing the SPI BUS interface method, designed for high reliability and efficiency in data storage and retrieval.

FEATURES

· Supports high-speed clock operations up to 5MHz.
· Features a wait function via the HOLD terminal.
· Allows setting parts or all of the memory arrays as read-only.
· Operates on a single power source from 1.8V to 5.5V, ideal for battery-powered devices.
· Includes a page write mode for initial value settings during factory shipment.
· Ensures highly reliable connections using Au pad and Au wire.
· Compatible with SPI bus interface modes (CPOL, CPHA) = (0, 0), (1, 1).
· Offers auto erase and auto end functions during data rewrite.
· Low current consumption: 1.5mA (Typ.) at write, 1.0mA (Typ.) at read, and 0.1 μA (Typ.) at standby.
· Includes an address auto increment function during read operations.
· Provides multiple write mistake prevention functions including power-on write prohibition, command code write prohibition, WP pin write prohibition, and block setting via status registers.
· Ships with memory array initialized to FFh and status registers WPEN, BP1, BP0 set to 0.
· Data retention guaranteed for 40 years.
· Supports up to 1,000,000 data rewrite cycles.

APPLICATIONS

· Suitable for a wide range of applications requiring reliable non-volatile memory storage, particularly in environments where battery power is utilized.
