• Manufacturer Part Number: BR24L04F-W
• Description: 5128 bit electrically erasable PROM
• Manufacturer: Rohm

Memory ICs
• If an Acknowledge is detected, and no STOP condition is generated by the master (µ-COM), the device will continue to
• If an Acknowledge is not detected, the device will terminate further data transmissions and await a STOP condition
• The Sequential Read operation can be performed with both Current Read and Random Read.
Sequential read
transmit the data. [ It can transmit all data (4kbit 512word) ]
before returning to the standby mode.
Note) If an Acknowledge is detected with “Low” level, not “High” level, command will become Sequential Read.
LINE
SDA
So the device transmits the next data, Read is not terminated. In the case of terminating Read, input
Acknowledge with “High” always, then input stop condition.
