ROHM Semiconductor BR25G-5 SPI BUS EEPROMs
ROHM Semiconductor BR25G-5 SPI BUS EEPROMs are 16Kbit serial EEPROMs with an SPI BUS interface and 4 million write cycles. These EEPROMs feature a 32-byte page size, 2048 x 8-bit format, 1.6V to 5.5V supply voltage range, 20MHz clock frequency, and 3.5ms maximum write time. The ROHM Semiconductor BR25G-5 SPI BUS EEPROMs include an address auto-increment function at read operation and auto-erase and auto-end functions at data rewrite. Typical applications include AV equipment, OA equipment, telecommunication equipment, home electronic appliances, and amusement equipment.
