The 5 ms write cycle time per word or page means the bus is held during writes; the host firmware must account for this delay in the I²C transaction sequence.","metaTitle":"ROHM BR24T04F-WE2 EEPROM 4Kbit I2C 400kHz 8-SOP","metaDescription":"ROHM BR24T04F-WE2 EEPROM, 4Kbit, I²C 400kHz, 1.6-5.5V, -40 to +85°C, 8-SOP.
