1. Overview

Serial sound interface

 Six-channel bidirectional serial transfer

 Duplex communication (channels 0, 1, 3, and 5)

 Support of various serial audio formats

 Support of master and slave functions

 Generation of programmable word clock and bit clock

 Multi-channel formats

 Support of 8, 16, 18, 20, 22, 24, and 32-bit data formats

 Support of eight-stage FIFO for transmission and reception

 Support of TDM mode

 Support of WS continue mode in which the SSIWS signal is not stopped.

 Support of direct transfer to the SCUX module

 A change of the sampling frequency can be detected.

Media local bus

 Conforms with version 2.0 of the MediaLB standard. Data transfer at up to 50 Mbps is possible.

SCUX

 Sampling rate conversion

—Asynchronous or synchronous sampling rate conversion is possible.

—Sampling rate (synchronous mode)

Note: The selectable sampling rates depend on the number of used channels and rate ratio.

Input [kHz]: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48, 64, 88.2, or 96 is selectable.

Output [kHz]: 8, 16, 24, 44.1, 48, or 96 is selectable.

—Sampling rate (asynchronous mode)

Note: The selectable sampling rates depend on the number of used channels and rate ratio.

Input/output [kHz]: 1 to 96

—Data format: 16 or 24 bits

 Digital volume and mute functions

—The digital volume can be set within the range from a multiple of 0 to 8 (−120 to 18 dB)

—Volume ramping supports soft mute, fade-in, and fade-out.

—The zero crossing mute function can apply muting at zero-crossing points.

 Mixer

—Data of two to four source systems can be mixed (added together) into one system.

—The ratio to add the sources can be set.

—Direct transfer to the serial sound interface module is supported.

CAN interface

 Five channels

 ISO11898-1 compliant

 Message buffer:

—Up to 64 5-channel receive message buffers: shared among all channels.

—16 transmit message buffers per channel

IEBusTM controller

 Conforms with the IEBus protocol (communication modes 1 and 2).

 Transfer rates: approximately 18 kbps (in communication mode 1),

approximately 27 kbps (in communication mode 2)

 Maximum numbers of bytes for transfer: 32 bytes/frame (in communication mode 1),

128 bytes/frame (in communication mode 2)

 Operating clock: 8 MHz

Note: Input of peripheral clock 0 (P0φ) running at 32 MHz is required.

Renesas SPDIF interface

 Support of IEC60958 standard (stereo and consumer use modes only)

 Sampling frequencies of 32 kHz, 44.1 kHz, and 48 kHz

 Audio word sizes of 16 to 24 bits per sample

 Biphase mark encoding

 Double buffered data

 Parity encoded serial data

 Simultaneous transmit and receive

 Receiver autodetects IEC 61937 compressed mode data.

CD-ROM decoder

 Support of five formats: Mode 0, mode 1, mode 2, mode 2 form 1, and mode 2 form 2

 Sync codes detection and protection

 (Protection: When a sync code is not detected, it is automatically inserted.)

 Descrambling

 ECC correction

—P, Q, PQ, and QP correction

—PQ or QP correction can be repeated up to three times.

 EDC check

Performed before and after ECC

 Mode and form are automatically detected.

 Link sectors are automatically detected.

 Buffering data control

Buffering CD-ROM data including Sync code is transferred in specified format, after the data is

descrambled, corrected by ECC, and checked by EDC.
