lc75100m Sanyo Semiconductor Corporation, lc75100m Datasheet - Page 9

• Manufacturer Part Number: lc75100m
• Description: Digital Echo Ic With Microphone Amplifier Circuit
• Manufacturer: Sanyo Semiconductor Corporation

2 Serial data input
(2) I
Data is transferred MSB first.
One unit is made up of 8 bits. ACK is returned by the slave for acknowledgement.
The slave IC reads the data on the rising edge of SCL.
The master IC changes the data on the falling edge of SCL.
1 Control registers
• CL: Normal Hi
• CL: Normal Low
Note: The LC75100M can be used in the receive only mode if the LSB is set to 0.
• Slave Address
I
The I
It controls the start and stop condition with SDA (Serial Data) and SCL (Serial Clock). The outputs of these signals
are of open drain type and wired OR.
