The PA5331 is a high performance, low power and low cost
audio CODEC. It consists of 2-ch ADC, 2-ch DAC,
microphone amplifier, headphone amplifier, digital sound
effects, and analog mixing and gain functions.
The multi-bit delta-sigma modulators make the device with low
sensitivity to clock jitter and low out of band noise.

CLOCK MODES AND SAMPLING FREQUENCIES
According to the input serial audio data sampling frequency, the device can work in two speed modes: single speed or double speed.
The ranges of the sampling frequency in these two modes are listed in Table 1. The device can work either in master clock mode or
slave clock mode.
In slave mode, LRCK and SCLK are supplied externally. LRCK and SCLK must be synchronously derived from the system clock with
specific rates. The device can auto detect MCLK/LRCK ratio according to Table 1. The device only supports the MCLK/LRCK ratios
listed in Table 1. The LRCK/SCLK ratio is normally 64.

MCLK/LRCK Ratio
Single Speed
8kHz – 50kHz
256, 384, 512, 768, 1024
Double Speed
50kHz – 100kHz
128, 192, 256, 384, 512
In master mode, LRCK and SCLK are derived internally from MCLK. The available MCLK/LRCK ratios and SCLK/LRCK ratios are
listed in Table 2Table 2 Master Mode Sampling Frequencies and MCLK/LRCK Ratio

MICRO-CONTROLLER CONFIGURATION INTERFACE
The device supports standard SPI and 2-wire micro-controller configuration interface. External micro-controller can completely
configure the device through writing to internal configuration registers. Please see section for the details of configuration register
definition.
The identical device pins are used to configure either SPI or 2-wire interface. In SPI mode, pin CE, CCLK and CDATA function as
SPI_CSn, SPI_CLK and SPI_DIN. In 2-wire mode, pin CE, CCLK and CDATA function as AD0, SCL and SDA. To select SPI mode,
apply high to low transition signal to CE pin. Otherwise the device will operate in 2-wire interface mode.
SPI
PA5331 has a SPI (Serial Peripheral Interface) compliant synchronous serial slave controller inside the chip. It provides the ability to
allow the external master SPI controller to access the internal registers, and thus control the operations of chip.
All lines on the SPI bus are unidirectional: The SPI_CLK is generated by the master controller and is primarily used to synchronize
data transfer, the SPI_DIN line carries data from the master to the slave; SPI_CSn is generated by the master to select PA5331.
The timing diagram of this interface is given in Figure 1. The high to low transition at SPI_CSn pin indicates the SPI interface
selected. Each write procedure contains 3 words, i.e. Chip Address plus R/W bit, internal register address and internal register data.
Every word length is fixed at 8 bits. The input SPI_DIN data are sampled at the rising edge of SPI_CLK clock. The MSB bit in each
word is transferred firstly. The transfer rate can be up to 10M bps.

Figure 1 SPI Configuration Interface Timing Diagram
2-wire
2-wire interface is a bi-directional serial bus that uses a serial data line (SDA) and a serial clock line (SCL) for data transfer. The
timing diagram for data transfer of this interface is given in Figure 2. Data are transmitted synchronously to SCL clock on the SDA line
on a byte-by-byte basis. Each bit in a byte is sampled during SCL high with MSB bit being transmitted firstly. Each transferred byte is
followed by an acknowledge bit from receiver to pull the SDA low. The transfer rate of this interface can be up to 100k bps.
Figure 2 Complete Data Transfer for 2-wire Interface
A master controller initiates the transmission by sending a ―start‖ signal, which is defined as a high-to-low transition at SDA while SCL
is high. The first byte transferred is the slave address. It is a seven-bit chip address followed by a RW bit. The chip address must be
001000x, where x equals AD0 (pin CE). The RW bit indicates the slave data transfer direction. Once an acknowledge bit is received,
the data transfer starts to proceed on a byte-by-byte basis in the direction specified by the RW bit. The master can terminate the
communication by generating a ―stop‖ signal, which is defined as a low-to-high transition at SDA while SCL is high.

In 2-wire interface mode, the registers can be written and read. The formats of ―write‖ and ―read‖ instructions are shown in Table 3
and Table 4. Please note that, to read data from a register, you must set R/W bit to 0 to access the register address and then set R/W
to 1 to read data from the register. There are no acknowledge bit after data to be written or read, this is the only difference from the
2
I C protocol.

CONFIGURATION REGISTER DEFINITION
SPI and 2-wire configuration interface share the same registers because there is only one interface active at any time. There are total
of 53 user programmable 8-bit registers in this device. These registers control the operations of ADC and DAC. External master
controller can access these registers by using the slave address specified in RAM (Register Address Map) register as shown in the
Table 5.

DIGITAL AUDIO INTERFACE
The PA5331 provides four formats of serial audio data interface to the input of the DAC or output from the ADC through LRCK, SCLK
2
and SDIN/SDOUT pins. The four formats are I S, left justified, right justified and DSP/PCM mode. DAC input DSDIN is sampled by
PA5331 on the rising edge of DSCLK. ADC data is out on ASDOUT and changes on the falling edge of ASCLK. The relationship of
SDATA (SDIN/SDOUT), SCLK and LRCK with the three formats is shown through Figure 3 to Figure 7.
