Architecture Overview

SLES061B—November 2002—Revised January 2004
TAS5036A
The TAS5036A supports the standard-mode I
2
C bus operation (100 kHz maximum) and the fast I
2
C bus
operation (400 kHz maximum). The TAS5036A performs all I
2
C operations without I
2
C wait cycles.
The I
2
C bus employs two signals, SDA (data) and SCL (clock), to communicate between integrated circuits
in a system. Data is transferred on the bus serially one bit at a time. The address and data are transferred in
byte (8 bit) format with the most significant bit (MSB) transferred first. In addition, each byte transferred on the
bus is acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with
the master device driving a start condition on the bus and ends with the master device driving a stop condition
on the bus. The bus uses transitions on the data terminal (SDA) while the clock is high to indicate start and
stop conditions. A high-to-low transition on SDA indicates a start, and a low-to-high transition indicates a stop.
Normal data bit transitions must occur within the low time of the clock period. These conditions are shown in
Figure 213. The master generates the 7-bit slave address and the read/write (R/W) bit to open
communication with another device and then waits for an acknowledge condition. The TAS5036A holds SDA
low during acknowledge clock period to indicate an acknowledgement. When this occurs, the master transmits
the next byte of the sequence. Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte).
All compatible devices share the same signals via a bidirectional bus using a wired-AND connection. An I
2
C
external pullup resistor must be used for the SDA and SCL signals to set the high level for the bus.

C Sequence
There are no limits on the number of bytes that can be transmitted between start and stop conditions. When
the last word transfers, the master generates a stop condition to release the bus. A generic data transfer
sequence is also shown in Figure 213.
The 7-bit address for the TAS5036A is 001101X, where X is a programmable address bit. Using the CS0
terminal on the device, the LSB address bit is programmable to permit two devices to be used in a system.
These two addresses are licensed I
2
C addresses and do not conflict with other licensed I
2
C audio devices.
To communicate with the TAS5036A, the I
2
C master uses 0011010 if CS0 = 0 and 0011011 if CS0 = 1. In
addition to the 7-bit device address, an 8-bit register address is used to direct communication to the proper
register location within the device interface.
Read and write operations to the TAS5036A can be done using single-byte or multiple-byte data transfers.
2.5.1 Single-Byte Write
As shown in Figure 214, a single-byte data write transfer begins with the master device transmitting a start
condition followed by the I
2
C device address and the read/write bit. The read/write bit determines the direction
of the data transfer. For a write data transfer, the read/write bit is 0. After receiving the correct I
2
C device
address and the read/write bit, the TAS5036A device responds with an acknowledge bit. Next, the master
transmits the address byte or bytes corresponding to the TAS5036A internal memory address being
accessed. After receiving the address byte, the TAS5036A again responds with an acknowledge bit. Next, the
master device transmits the data byte to be written to the memory address being accessed. After receiving
the data byte, the TAS5036A again responds with an acknowledge bit. Finally, the master device transmits
a stop condition to complete the single-byte data write transfer.
