S-24C16D

2-WIRE SERIAL E2PROM

Unspecified 

Rev.3.0_02_U

 Initial Delivery State

Initial delivery state of all addresses is "FFh".

2-WIRE SERIAL E2PROM

S-24C02D/04D/08D16D

 Operation

1. Initialization operation after power-on

By a power-on-clear circuit, this IC initializes the internal circuit at the time of power-on. Perform the beginning (start

condition) of the instruction transmission to this IC after the initialization by the power-on-clear circuit. Regarding the

datails of power-on-clear, refer to "5. Power-on-clear circuit" in " Usage".

2. Start condition

Start is identified by a "H" to "L" transition of the SDA line while the SCL line is stable at "H".

Every operation begins from a start condition.

3. Stop condition

Stop is identified by a "L" to "H" transition of the SDA line while the SCL line is stable at "H".

When a device receives a stop condition during a read sequence, the read operation is interrupted, and the device

enters standby mode.

When a device receives a stop condition during a write sequence, the reception of the write data is halted, and this IC

initiates a write cycle.
