PCM3052A
SLES160 – NOVEMBER 2005
The several built-in functions of the PCM3052A can be controlled through the I2C format serial-control port, SDA
(pin 18) and SCL (pin 19). The PCM3052A supports the I2C serial bus and the data transmission protocol for
standard mode as a slave device. This protocol is explained in I2C specification 2.0.
Serial control is available even during the power-down state and without a system clock, except when the MRST
bit = 0 or I2CEN (pin 21) = LOW.

The PCM3052A has seven bits for its own slave address. The first six bits (MSBs) of the slave address are
factory preset to 100011. The next bit of the address byte is the device select bit which can be user-defined by
ADR (pin 20). A maximum of two PCM3052As can be connected on the same bus at one time. Each PCM3052A
responds when it receives its own slave address.
A master device must control packet protocol, which consists of start condition, slave address with read/write bit,
data if write or acknowledgement if read, and stop condition. The PCM3052A supports slave receiver function.
