Functionality

RAC

Row Address Clock; an open drain output. The RAC pin goes LOW TRACLO

before the end of each row of memory, and returns HIGH at exactly the end

of each row of memory.

INT

Interrupt Output; an open drain output indicating that a set EOM bit has

been found during Playback, or that the chip is in an Overflow (OVF)

condition. This pin remains LOW until a Read Status command is executed.

MCLK

This pin allows the internal clock of the Voice record/playback system to be

externally driven for enhanced timing precision. This pin is grounded for

most applications. It is required for the CODEC operation.

SCL

Serial Clock Line is part of the I

2C serial bus. It is used to clock the data into

and out of the I

2C interface.

SDA

Serial Data Line is part of the I

2C serial bus. Data is passed between

devices on the bus over this line.

Input pin that supplies the LSB for the I

2C Slave Address.

Input pin that supplies the LSB +1 bit for the I

2C Slave Address.

MIC+

Differential positive Input to the microphone amplifier.

MIC-

Differential negative Input to the microphone amplifier.

MICBS

Microphone Bias Voltage

ACAP

AGC Capacitor connection. Required for the on-chip AGC amplifier.

SP+

Differential Positive Speaker Driver Output.

SP-

Differential Negative Speaker Driver Output. When the speaker outputs are

in use, the AUX OUT output is disabled.

AUX IN

Auxiliary Input.

AUX OUT

Auxiliary Output. This is one the analog outputs for the device. When this

output is in use, the SP+ and SP- outputs are disabled.

SDI

Serial Digital Audio PCM Input.

SDIO

Serial Digital Audio PCM Output or I

2S Input/Output.

Digital audio PCM Frame sync (FS) or I

2S Word Sync (WS).

SCK

Digital audio PCM or I

2S Serial Clock.

VCCD

7,8

1,28

Positive Digital Supply pins. These pins carry noise generated by internal

clocks in the chip. They must be carefully bypassed to Digital Ground to

ensure correct device operation.

VSSD

13,14

6,7

5,6

Digital Ground pins.

VSSA

1,15,21

8,14,22

11,14,23

Analog Ground pins.

VCCA

Positive Analog Supply pin. This pin supplies the low level audio sections for

the device. It should be carefully bypassed to Analog Ground to ensure

correct device operation.

No Connection
