9 / 57 page  October 2000 Page 8 2.3 PINOUT TABLE Pin Name Pin No. 28-pin TSOP Pin No. 28-pin SOIC Functionality RAC 3 24 Row Address Clock; an open drain output. The RAC pin goes LOW TRACLO 1 before the end of each row of memory and returns HIGH at exactly the end of each row of memory. INT 4 25 Interrupt Output; an open drain output that indicates 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. XCLK 5 26 This pin allows the internal clock of the device to be driven externally for enhanced timing precision. This pin is grounded for most applications. SCL 8 1 Serial Clock Line is part of the I 2C interface. It is used to clock the data into and out of the I 2C interface. SDA 10 3 Serial Data Line is part of the I 2C interface. Data is passed between devices on the bus over this line. A0 11 4 Input pin that supplies the LSB for the I 2C Slave Address. A1 9 2 Input pin that supplies the LSB +1 bit for the I 2C Slave Address. MIC+ 16 8 Differential Positive Input to the microphone amplifier. MIC- 17 10 Differential Negative Input to the microphone amplifier. ANA OUT+ 18 11 Differential Positive Analog Output for ANA OUT of the device. ANA OUT- 19 12 Differential Negative Analog Output for ANA OUT of the device. ACAP 20 13 AGC Capacitor connection. Required for the on-chip AGC amplifier. SP+ 23 16 Differential Positive Speaker Driver Output. SP- 21 14 Differential Negative Speaker Driver Output. When the speaker outputs are in use, the AUX OUT output is disabled. ANA IN 25 18 Analog Input. This is one of the gain adjustable analog inputs of the device. AUX IN 26 19 Auxiliary Input. This is one of the gain adjustable analog inputs of the device. AUX OUT 27 20 Auxiliary Output. This is one the analog outputs of the device. When this output is in use, the SP+ and SP- outputs are disabled. VCCD 6,7 27,28 Positive Digital Supply pins. These pins carry noise generated by internal clocks in the chip. They must be carefully bypassed to Digital Ground to insure correct device operation. VSSD 12,13 5,6 Digital Ground pins. VSSA 2,15,22 9,15,23 Analog Ground pins. VCCA 24 17 Positive Analog Supply pin. This pin supplies the low level audio sections of the device. It should be carefully bypassed to Analog Ground to insure correct device operation. NC 1,14,28 7,21,22 No Connect. 1 See the Parameters section of on page 38. |
